New Features
New Features in 8.10.2
PROXY Pro 8.10.2 introduces the following new features and capabilities:
 Host on Demand for Macintosh OS X: The PROXY Pro Web Console
now supports launching a Host on Demand on the Macintosh OS X
operating systems.
 Select Single Monitor of Multi-monitor Host: The installed Master
and Click-Once Connection Window supports a new option to set the
view to be only one monitor of a Host that has multiple monitors.
 Automatic Recording: When this feature is enabled, all matching live
Master connections to Hosts for remote control will be recorded. This
will be configurable in the Web Console and includes features like local
disk free space monitoring.
 HOD “Elevate” is now “Pin” and there will be “Session” or
“Pinned” HODs: The type of session will be identifiable in the Web
Console with new graphics. An on demand Host will be marked with a
“D” and a separate “pin” icon will be highlighted if the HOD session is
pinned.
 ClickOnce connection window can suppress Host mouse and
keyboard input: This now brings functionality available only in the
installed Master to the ClickOnce connection window.
 Utility to clear the Windows ClickOnce cache: The Windows
operating system does not provide a convenient way to do this. We
have now built this functionality into the Web Console itself.
 Improved ability to customize and retain Web Console changes on
upgrade: Customization of the Web Console landing page and colors
are now easier to put in place and will be maintained when the software
is upgraded.
New Features in 8.10.1

PROXY Pro 8.0.2 introduced the following new features and capabilities:
 Concurrent User License Mode: In this mode, the Gateway will
monitor the number of simultaneous Gateway users according to
account type (Administrative, Master, Personal) (see PROXY Pro Web
Console Operating Guide)
 Inactivity Timeouts: To free up concurrent user licenses when users
are connected to the Gateway but not active, Web Console, Master and
Gateway Administrator will be automatically disconnected from the
Gateway, and input control will be automatically released from Remote
Desktop or Master Connection Window (see PROXY Pro Gateway
Administrator Guide)
 Automatic Grouping of Hosts: Ability to configure Hosts to
automatically report to custom Gateway group(s) according to custom or
generic rules (see PROXY Pro Gateway Administrator Guide)

 Web Console: A new server-side application that enables browser-
based access to the Gateway Server (see PROXY Pro Web Console
Operating Guide)
 Remote Desktop Window: Ability to launch a Remote Desktop window
through the Web Console, bypassing need to have an installed Master.
No administrative rights needed and no reboot required (see PROXY
Pro Web Console Operating Guide)
 Citrix XenApp support: Option to restrict injection of Terminal Services
Host instances into "desktop" sessions only, and not into "application"
sessions. Requires XenApp Enterprise or Platinum Edition. (see PROXY
Pro Host Guide)
 Kernel-mode Screen Capture driver: The kernel-mode screen capture
driver is now available for Windows 7, Vista and Windows 2008 Server.
In many situations, the kernel-mode screen capture driver will
outperform the default user-mode screen capture driver (see PROXY
Pro Host Guide)
 Input Suppression: Ability to turn off keyboard and mouse input on the
remote desktop machine for Windows 7, Vista and Windows 2008
Server (see PROXY Pro Host Guide)
 Assignment of Hosts: Ability to automate the assignment of Hosts to
custom Gateway Groups using Windows PowerShell scripting (see
PROXY Pro Host Guide)
 Address Bindings: Ability to bind the SSL and TCP network protocols
to all addresses or to select specific addresses on the Gateway Server
(see PROXY Pro Gateway Administrator Guide)
New Features in 7.0.5
PROXY Pro 7.0.5 was performance enhancement release.
New Features in 7.0.4
PROXY Pro 7.0.4 introduced the following new features and capabilities:
 Connection notification enhancements: Additional connection
information is included in “popup toast” notification on the Host, in
particular the identity of the Master user requesting connection. If initial
connection is Gateway-managed, subsequent connections will cause
the toast popup to reappear. Previously, the Host toast notification only
appeared on the first connection.
 Active users list: A new option is available when right-clicking the
Proxy icon in the system tray on the Host which will show all the active
users (Masters) connected to it and/or any active recordings.
 End-to-end authentication: For certain services (such as file transfer,
remote Host administration, and remote management), the Master end-
user may be asked to authenticate directly to the Host, even if the
Master has already authenticated successfully to the Gateway.
6 PROXY Pro 8.10.2 January 2015
Previously, the Host simply denied these services if proper credentials
were not available.
 Extension tags: To support extensibility for 3rd-party applications that
want to integrate the PROXY Pro solution, extension tags are now
available for collecting and persisting metadata attributes of the Host or
Host connection (e.g. phone extension for the phone next to the Host
computer). Extension tags are name/value pairs that can be used to
collect custom information for any Host. A field for an extension tag has
also been added to store custom information about a PROXY Pro
recording.
 Restart in Safe Mode: The Host now includes the ability to reboot in
Safe Mode. Note that Host will run with user-mode screen capture
capabilities only since the goal is to minimize the number of kernel
drivers loaded on a safe-boot.
 Display option enhancements: The Fit-to-Window display option in the
Master has been modified to preserve the Host screen aspect ratio, and
to center the display in the available space. Also, text mode screen is
now centered in available space in all display modes.
New Features in 7.0.3
PROXY Pro 7.0.3 was an internal maintenance release.
New Features in 7.0.2
PROXY Pro 7.0.2 introduced the following new features and capabilities:

glass on Windows Vista and Windows 7 desktops.
 Clipboard now supports automatic sharing between Host and Master.
 Master tool bar and menu include several improvements including new
option for sending Ctrl-Alt-Del to Host from toolbar.
 Queue for Status Update enables the Gateway to immediately poll any
Host for a status update.
 Active Host Status and Reverse Connections group which is located
in the Active Status folder on the Gateway, has been split into two
separate groups: Pending Host Status Updates and Reverse
Connections groups.
 PHSETUP command now has a reset option.
New Features in 7.0.1
PROXY Pro 7.0.1 introduced the following new features and capabilities:
 TS Host configuration: The Root Host can be configured to restrict the
injection of a Host image to Terminal Services sessions that meet
predetermined criteria (previously, the Root Host injected a Host image
into every TS session) The criteria for determining which TS sessions
should receive a Host image are available on the Terminal Services tab
in the Root Host control panel.
Release Notes PROXY Pro 8.10.2 7
 Full Screen mode now supports auto-scrolling in all directions.
 Screen capture at startup and at subsequent checkpoints are now
using higher compression and therefore transmit faster.
 Deployment Tool now includes support for customizing missing Host
security settings.
New Features in 7.0.0
PROXY Pro 7.0.0 introduced the following new features and capabilities:
 Windows 7 support: PROXY Pro 7.0.0 provides full support (remote
access, remote control, remote management) for Windows 7 computers,
including 32- and 64-bit platforms.
 Windows Server 2008 R2 support: PROXY Pro 7.0.0 provides full
support (remote access, remote control, remote management) for
Windows Server 2008 R2 computers (64-bit platforms only).

 Screen Recording Playback via URL: PROXY Pro 7.0.0 includes ability
for Master to playback a PROXY Pro screen recording from a standard
web server over HTTP or HTTPS.
 RDP compatibility: If a remote computer is hosting an active RDP
session, PROXY Pro 7.0.0 Host will capture and provide input control to
the RDP session.
 Active Directory integration: PROXY Pro 7.0.0 Deployment Tool can
now be used to discover computers and OUs in Active Directory
domains, install new PROXY Pro software, upgrade existing software,
and/or push configuration changes to existing software.
8 PROXY Pro 8.10.2 January 2015
Enhancements and Fixes
New Enhancements and Fixes in 8.10.2
Following is a list of major enhancements in PROXY Pro 8.10.2:
 Updated Web Console graphics: Better distinction between the
various types of Hosts (e.g. Installed, On demand session, On demand
pinned, Terminal Services, VDI)
 Automatic Elevation/Pinning of HOD: When a Host on Demand is
launched, it will automatically start as elevated/pinned if the console
user has administrative rights.
 Expanded search functionality for recordings in Web Console: The
Web Console “Recordings” page will allow the user to search for
recordings based on more criteria.
 WC improved load time and performance with large numbers of
Hosts: The time it takes for the Web Console landing page and
dashboard to show up has been reduced. This is particularly noticeable
in environments with thousands of Hosts reporting in.
 Copy Text and Graphics to Clipboard: The installed Master and Click-
Once Connection Window now support copying both text-format data
and a graphic image when the Host screen is in “plain text” display
mode. Note that this primarily occurs with certain error messages, and
for the Gateway Server “System” Hosts. This change merges the
former “Copy Text to Clipboard” and “Copy Graphics to Clipboard”
functions into a single “Copy Host Screen to Clipboard” option.
 Gateway Server Host Grouping Rule for Active Directory: The
Gateway Server now supports two styles of Active Directory-based Host
grouping rules.
 Various SDK improvements: Updates to the SDK for better
compatibility with newer versions of Visual Studio have been
made. Additionally, the SDK support for x64 is now included in the main
packaging.
 Alignment of the installed Master and ClickOnce connection
windows: Changes have been implemented upon both products in
order to make them as close as possible despite being different
underlying technologies.
Following is a list of major defect fixes in PROXY Pro 8.10.2:
 Improved compatibility for remote controlling devices without a mouse:
(e.g. Kiosks and touch-screen tablets)
 Replaced OpenSSL library with version 1.0.1l, which is a security
release of OpenSSL. Customers with internet-facing Gateway Servers
listening for SSL connections are encouraged to upgrade to this release.
 Improved handing of X-Forwarded-For header processing
 Host station name was not being updated at the Gateway Server if Host
maintained a reverse connection with the Gateway.
 Gateway Server now ensures the Gateway Companion Service
(required by the Web Console) is running when it starts.
 Fixed issues that impacted the PROXY Pro Remote Desktop application
for iOS. Note well that the iOS app version 8.10.1051 or later is
required for use with PROXY Pro v8.10.2.
Release Notes PROXY Pro 8.10.2 9
 Various improvements to the ClickOnce connection window application
launched from the Web Console, including: Host station name is shown
instead of Host ID in dialog prompts; error messages and reporting is
improved.
New Enhancements and Fixes in 8.10.1 (Hotfix #3)
Following is a list of enhancements in PROXY Pro 8.10.1 hotfix#3:
 An error in the TCP/WS transport resulted in a resource leak if an HTTP
request was made to a Gateway Server or Host on the port it was
listening for TCP connections. This eventually resulted in 0xC004C055
errors. All customers are encouraged to upgrade their Gateway Servers
running v8.10.0 or later to this release, and are encourage to plan to
upgrade Hosts as well.
 The Gateway Server could end up with a completely blank workstation
record instead of a properly deleted record under very specific
circumstances; this no longer occurs.
 Web Console has a performance fix that resolves issues when users
have access to large numbers (multiple thousands) of Hosts. Customers
with over 5000 managed Hosts are encouraged to upgrade the Web
Console to this release.
 Web Console now supports an alternate addin to provide ClickOnce
deployment support for the Google Chrome browser. Note that Chrome
support for addins is changing this year, and the new addin may not
provide a long-term solution. A future maintenance release will provide
support for the new Chrome browser.
New Enhancements and Fixes in 8.10.1 (Hotfix #2)
Following is a list of major defect fixes in PROXY Pro 8.10.1 (Hotfix #2):
 Gateway Server and Host have compatibility fixes for the PROXY Pro
Remote Desktop application for iOS. Customers using the iOS
application in their environment are encouraged to upgrade to this
release to avoid any issues.
 New Host station name macros are introduced. These macros get
values from Active Directory about the logged-in console user. The
properties are:
o %USERUPN% is the user principal name format of the console
user, or blank if the user is not a domain account
o %USERUPN+% is the same as above, but provides the
“authorityusername” account name for local accounts.
o %USERDISPLAY% is the user display name
o %USERDISPLAY+% is the user account display name, or the
account name in “authorityusername” format if the account
display name is not set
o %USEREMAIL% is the user account email address, or blank if
the user is not a domain account
10 PROXY Pro 8.10.2 January 2015
o %USEREMAIL+% is the same as above, but provides the
“authorityusername” account name if the email address is blank.
 Web Console and Gateway Server now respect the X-Forwarded-For
header on HTTPS (for Web Console) and WS/WSS (for Gateway Server)
connections. In conjunction with the “trusted device list” setting in the
Gateway Server, this allows the software to work well with reverse proxy
servers like Microsoft Application Request Routing (ARR).
 Master and Connection Window send entered keyboard input to Host
promptly; previously, the keystrokes could be cached briefly, introducing
delay in typing feedback.
 Host did not send status reports to Gateways with which it had an active
status reverse connection in v8.10.0 or later. This primarily affected the
updating of the logged-in console user, or Host station name changes,
and is fixed in this release.
 Replaced OpenSSL library with version 1.0.1i, which is a security release
of OpenSSL. Customers with internet-facing Gateway Servers listening
for SSL connections are encouraged to upgrade to this release.
 Web Console now marks cookies as “secure” and “httpOnly” (when
possible) for increased security. All Web Console installations are
encouraged to upgrade to this release.
New Enhancements and Fixes in 8.10.1 (Hotfix #1)
Following is a list of major defect fixes in PROXY Pro 8.10.1 (Hotfix #1):
 Replaced OpenSSL library with version 1.0.1h, which includes fixes for
newly found security vulnerabilities post the “Heartbleed” fix. Anyone with
Gateway Server version 7.0.x through 8.10.1 should upgrade to PROXY
Pro Gateway 8.10.1 (Hotfix #1), especially if Gateway Server is
configured to listen for connections directly from the Internet.
New Enhancements and Fixes in 8.10.1
Following is a list of major enhancements in PROXY Pro 8.10.1:
 Explicit web proxy support: If a customer uses a web proxy server to
manage internet traffic coming into or going out of its network, PROXY
Pro applications that are outside the network (such as Host or Master)
will be able to negotiate automatically with the web proxy to reach a
Gateway server inside the network.
 JSON file delivery mode: If Web Console is behind a firewall, the location
of the JSON file for Host on Demand can be pre-configured, eliminating
the need to make an additional HTTP request.
 Host services enabled by default configuration option is now applicable
only to Host on Demand. Default settings are available in the Web
Console Settings > Host on Demand section of the Gateway tab in the
Web Console.
Release Notes PROXY Pro 8.10.2 11
 Local network address exceptions: The Gateway server allows for one or
more addresses or address ranges to be reclassified as external, even if
they appear in the range of local network addresses.
 Trusted Device list: If the Windows account user has any trusted
devices, they can be added to list of machines that will be granted
access to the Gateway server.
New Enhancements and Fixes in 8.10.0 (Hotfix #1)
Following is a list of major defect fixes in PROXY Pro 8.10.0 (Hotfix #1):
 Replaced OpenSSL library with version 1.0.1g, which includes fix for the
"Heartbleed" vulnerability. Anyone with Gateway Server version 7.0.x
through 8.10.0 should upgrade to PROXY Pro Gateway 8.10.1 (Hotfix
#1), especially if Gateway Server is configured to listen for connections
directly from the Internet.
New Enhancements and Fixes in 8.10.0
Following is a list of major enhancements in PROXY Pro 8.10.0:
 View/edit Host services enabled at connection time: Host user will be
able to specify which Host services to enable by default when Remote
Desktop connections are established; if Permission to Connect is
enabled, then Host user will be able to view/edit the list of Host services
to enable for each Remote Desktop connection request.
 Permission to Connect suppression option: If Permission to Connect is
enabled, this new option will suppress the Permission to Connect
requirement if the Host desktop is locked or waiting for logon
 Toast notification for any active connections: When the Host user logs in,
he/she will be presented with a list of any Account Users with active
Remote Desktop connections to the Host in a toast popup notification
window
 Import/export Host settings in JSON format: Host settings can be
exported to a text file in JavaScript Object Notation (JSON) format; Host
settings can also be imported from a text file in JSON format.
 Connect to Host settings options: New security options for accessing
Host settings from the Host tray icon and the Host Control Panel itself
allow for connection to the Host settings as different user.
 Web Console database overflow protection: Unneeded data is now
regularly purged from the SQL database.
 More Host Grouping Rules: Additional grouping rules have been added
to allow for more flexibility in creating custom collections of Hosts (see
PROXY Pro Gateway Guide)
 Peer-to-Peer Host Administration: Allows access to Host settings when
Host is configured to accept connections through listed Gateways only.
Particularly useful for certain operations involving the Deployment Tool.
Following is a list of major defect fixes in PROXY Pro 8.10.0:
12 PROXY Pro 8.10.2 January 2015
 Duplicate GUID protection. Duplicate Host GUIDs can occur when the
HostPrep utility is not run on a Windows OS image containing PROXY
Pro Host software prior to deployment. This condition resulted in
unexpected behavior.
 Host for Terminal Services Session Host process injection issue
resolved. This was a regression from version 7 to version 8.0 and was
seen only on Windows Server 2003. (Back-ported to 8.0.2 Hotfix #4).
This allows for more robust compatibility with software like Citrix XenApp.
Release Notes PROXY Pro 8.10.2 13
Additional Notes
Note on Encryption Fix in 7.0.4
Connection encryption, which in some circumstances was found to be
intermittent, has been fixed. Below is additional information about the defect, the
circumstances in which the defect may affect performance, and mitigation
options.
Defect Description
By default, connections between Proxy components (for example, Master-to-
Host, Gateway-to-Host, Master-to-Gateway) use encryption (the current version
is set by default to use the AES 256-bit cypher). We have determined that in
certain circumstances, a defect in the encryption code occasionally causes
encryption to be dropped, even though one or both Proxy components are
configured to use encryption.
This defect has been identified in Gateway and Workstation Editions of PROXY
Pro versions 5.20.0 through 7.0.2.
Defect Scenarios
This defect can affect both peer-to-peer and Gateway-managed connections.
There is no indication to the user when encryption is dropped (for example, the
Lock icon will still show in the status bar of the Master, and Gateway
Administrator will indicate encryption method being used in several places), nor
is there any error message associated with this defect.
However, the defect does not affect the following circumstances:
 Does not affect SSL connections. With SSL protocol, encryption is
explicitly enforced and is unaffected by this defect.
 Does not affect reverse connections. Reverse connections are typically
utilized when Host is outside the domain of the Gateway. Reverse
connections allow Hosts to safely and seamlessly navigate NATs and
firewalls and connect to a Gateway. This is arguably the most vulnerable
connection type (since it can involve sending information over the public
Internet) but it is not affected by this defect, i.e. encryption has been
observed to be always in force.
 The initial connection between Proxy components is not affected by this
defect, so the very first service activity (e.g. remote viewing, recording
playback) will not be affected.
Mitigation Options
Following are mitigation options for this defect:
 No action. For most customers, the intermittent enforcement of
encryption may not be a significant issue, and no action may be
necessary:
14 PROXY Pro 8.10.2 January 2015
o Only peer-to-peer or Gateway-managed connections within the
same domain are vulnerable to this defect, but most corporate
domains are protected and considered safe environments.
o Proxy data, while not encrypted, is encoded in a proprietary
format and compressed, so intercepting and decoding that data
would not be a casual challenge. Also note that this defect does
not affect the initial connection between Proxy components.
o The initial connection between Proxy components is not affected
by this defect, so connections made to accomplish one and only
one task will not be affected.
 Upgrade to version 7.0.4. This maintenance release contains a fix for
the root cause of the defect. The fix will enforce encryption when a 7.0.4
Proxy “client” (typically Master in peer-to-peer connections, or the Master
connecting to a Gateway in the first half of a Gateway-managed
connection, and the Gateway connecting to a Host in the second half)
communicates with a 7.0.2 or older component. Customers should
upgrade all Proxy components to 7.0.4 in order to ensure persistent
enforcement of encryption on their connections. At a minimum,
customers should upgrade Masters (and Gateways if present) to 7.0.4 to
ensure encryption is enforced. Hosts can be a client in reverse
connections but those are not affected by this defect. If a 7.0.2 or older
Proxy client application tries to connect to a 7.0.4 Host, and encryption is
requested but not enforced, the connection will be terminated and a new
error code generated (0xC004DEAD).
 Registry modification to existing Proxy components. For customers
with Proxy components from version 6.0.2 through 7.0.2, a simple
registry patch can be used to work around this defect. (Note: Customers
with Proxy components from version 5.20.0 to 6.0.1 must either upgrade
(at least the clients) to 7.0.4 or take no action.) As with the upgrade
option, customers should apply the registry patch to all computers
running Proxy software, but at a minimum, customers must apply the
patch to Masters (and Gateways if present). Also note that customers
must monitor deployment of new Masters and Gateways, and ensure that
registry patch is applied if 7.0.4 (or later) software is not used. If a new
Master or Gateway comes online and the patch is not applied, the defect
may be active and will not be noticeable.
o The registry setting for Windows x86 systems is:
[HKEY_LOCAL_MACHINESOFTWAREFunk Software, Inc.Proxy
v5Transport] "ShareSession"=dword:00000000
o The registry setting for Windows x64 systems is:
[HKEY_LOCAL_MACHINESOFTWAREWow6432NodeFunk Software,
Inc.Proxy v5Transport] "ShareSession"=dword:00000000

Note on Host for Terminal Services on Server 2003 x64 Fix
There is a bug in 64-bit Windows Server 2003 that hinders our ability to get the
identity of the user that’s logged in to the terminal services session. As a result,
the following limitations may be observed:
 If “%USER%” is in the station name, the name “Not-Logged-In” may be
seen instead of the real user name.
 The “User” column in the Gateway Administrator views should eventually
get the correct user name, but this is not guaranteed.
 We cannot impersonate the logged-in user, so end-to-end services like
file transfer and remote management will not work if simple password
authentication is used. Note that use of Windows Authentication is
strongly recommended over simple password, especially in terminal
services environments.
 File transfer with Windows Authentication cannot evaluate the paths for
the “Personal” and “Common” folder collections (which include
“Desktop”, “My Documents”, “Shared Documents”, etc.). Users can
navigate to these folders using their real paths, but the shortcuts do not
appear in the file transfer user interface.

If initial connection is Gateway-managed, subsequent connections will cause the toast popup to reappear. Previously, the Host toast notification only appeared on the first connection.  Active users list: A new option is available when right-clicking the Proxy icon in the system tray on the Host which will show all the active users (Masters) connected to it and/or any active recordings.  End-to-end authentication: For certain services (such as file transfer, remote Host administration, and remote management), the Master end- user may be asked to authenticate directly to the Host, even if the Master has already authenticated successfully to the Gateway.
  • 6. 6 PROXY Pro 8.10.2 January 2015 Previously, the Host simply denied these services if proper credentials were not available.  Extension tags: To support extensibility for 3rd-party applications that want to integrate the PROXY Pro solution, extension tags are now available for collecting and persisting metadata attributes of the Host or Host connection (e.g. phone extension for the phone next to the Host computer). Extension tags are name/value pairs that can be used to collect custom information for any Host. A field for an extension tag has also been added to store custom information about a PROXY Pro recording.  Restart in Safe Mode: The Host now includes the ability to reboot in Safe Mode. Note that Host will run with user-mode screen capture capabilities only since the goal is to minimize the number of kernel drivers loaded on a safe-boot.  Display option enhancements: The Fit-to-Window display option in the Master has been modified to preserve the Host screen aspect ratio, and to center the display in the available space. Also, text mode screen is now centered in available space in all display modes. New Features in 7.0.3 PROXY Pro 7.0.3 was an internal maintenance release. New Features in 7.0.2 PROXY Pro 7.0.2 introduced the following new features and capabilities:  Color depth reduction has been introduced in the Host screen capture algorithm to provide another option for bandwidth throttling.  Manage Visual Effects has been improved to include support for Aero glass on Windows Vista and Windows 7 desktops.  Clipboard now supports automatic sharing between Host and Master.  Master tool bar and menu include several improvements including new option for sending Ctrl-Alt-Del to Host from toolbar.  Queue for Status Update enables the Gateway to immediately poll any Host for a status update.  Active Host Status and Reverse Connections group which is located in the Active Status folder on the Gateway, has been split into two separate groups: Pending Host Status Updates and Reverse Connections groups.  PHSETUP command now has a reset option. New Features in 7.0.1 PROXY Pro 7.0.1 introduced the following new features and capabilities:  TS Host configuration: The Root Host can be configured to restrict the injection of a Host image to Terminal Services sessions that meet predetermined criteria (previously, the Root Host injected a Host image into every TS session) The criteria for determining which TS sessions should receive a Host image are available on the Terminal Services tab in the Root Host control panel.
  • 7. Release Notes PROXY Pro 8.10.2 7  Full Screen mode now supports auto-scrolling in all directions.  Screen capture at startup and at subsequent checkpoints are now using higher compression and therefore transmit faster.  Deployment Tool now includes support for customizing missing Host security settings. New Features in 7.0.0 PROXY Pro 7.0.0 introduced the following new features and capabilities:  Windows 7 support: PROXY Pro 7.0.0 provides full support (remote access, remote control, remote management) for Windows 7 computers, including 32- and 64-bit platforms.  Windows Server 2008 R2 support: PROXY Pro 7.0.0 provides full support (remote access, remote control, remote management) for Windows Server 2008 R2 computers (64-bit platforms only).  Mac, Linux support: PROXY Pro 7.0.0 provides support (remote access, remote control) for Macintosh and Linux computers running VNC server software (standard on Macs).  Wake-on-LAN support: PROXY Pro 7.0.0 includes ability to turn on remote computers that are configured to listen for Wake-on-LAN signal.  Remote Power Scheme management: PROXY Pro 7.0.0 includes new remote management tools that allows Master user to view and change power scheme settings on remote computers.  Screen Recording Playback via URL: PROXY Pro 7.0.0 includes ability for Master to playback a PROXY Pro screen recording from a standard web server over HTTP or HTTPS.  RDP compatibility: If a remote computer is hosting an active RDP session, PROXY Pro 7.0.0 Host will capture and provide input control to the RDP session.  Active Directory integration: PROXY Pro 7.0.0 Deployment Tool can now be used to discover computers and OUs in Active Directory domains, install new PROXY Pro software, upgrade existing software, and/or push configuration changes to existing software.
  • 8. 8 PROXY Pro 8.10.2 January 2015 Enhancements and Fixes New Enhancements and Fixes in 8.10.2 Following is a list of major enhancements in PROXY Pro 8.10.2:  Updated Web Console graphics: Better distinction between the various types of Hosts (e.g. Installed, On demand session, On demand pinned, Terminal Services, VDI)  Automatic Elevation/Pinning of HOD: When a Host on Demand is launched, it will automatically start as elevated/pinned if the console user has administrative rights.  Expanded search functionality for recordings in Web Console: The Web Console “Recordings” page will allow the user to search for recordings based on more criteria.  WC improved load time and performance with large numbers of Hosts: The time it takes for the Web Console landing page and dashboard to show up has been reduced. This is particularly noticeable in environments with thousands of Hosts reporting in.  Copy Text and Graphics to Clipboard: The installed Master and Click- Once Connection Window now support copying both text-format data and a graphic image when the Host screen is in “plain text” display mode. Note that this primarily occurs with certain error messages, and for the Gateway Server “System” Hosts. This change merges the former “Copy Text to Clipboard” and “Copy Graphics to Clipboard” functions into a single “Copy Host Screen to Clipboard” option.  Gateway Server Host Grouping Rule for Active Directory: The Gateway Server now supports two styles of Active Directory-based Host grouping rules.  Various SDK improvements: Updates to the SDK for better compatibility with newer versions of Visual Studio have been made. Additionally, the SDK support for x64 is now included in the main packaging.  Alignment of the installed Master and ClickOnce connection windows: Changes have been implemented upon both products in order to make them as close as possible despite being different underlying technologies. Following is a list of major defect fixes in PROXY Pro 8.10.2:  Improved compatibility for remote controlling devices without a mouse: (e.g. Kiosks and touch-screen tablets)  Replaced OpenSSL library with version 1.0.1l, which is a security release of OpenSSL. Customers with internet-facing Gateway Servers listening for SSL connections are encouraged to upgrade to this release.  Improved handing of X-Forwarded-For header processing  Host station name was not being updated at the Gateway Server if Host maintained a reverse connection with the Gateway.  Gateway Server now ensures the Gateway Companion Service (required by the Web Console) is running when it starts.  Fixed issues that impacted the PROXY Pro Remote Desktop application for iOS. Note well that the iOS app version 8.10.1051 or later is required for use with PROXY Pro v8.10.2.
  • 9. Release Notes PROXY Pro 8.10.2 9  Various improvements to the ClickOnce connection window application launched from the Web Console, including: Host station name is shown instead of Host ID in dialog prompts; error messages and reporting is improved. New Enhancements and Fixes in 8.10.1 (Hotfix #3) Following is a list of enhancements in PROXY Pro 8.10.1 hotfix#3:  An error in the TCP/WS transport resulted in a resource leak if an HTTP request was made to a Gateway Server or Host on the port it was listening for TCP connections. This eventually resulted in 0xC004C055 errors. All customers are encouraged to upgrade their Gateway Servers running v8.10.0 or later to this release, and are encourage to plan to upgrade Hosts as well.  The Gateway Server could end up with a completely blank workstation record instead of a properly deleted record under very specific circumstances; this no longer occurs.  Web Console has a performance fix that resolves issues when users have access to large numbers (multiple thousands) of Hosts. Customers with over 5000 managed Hosts are encouraged to upgrade the Web Console to this release.  Web Console now supports an alternate addin to provide ClickOnce deployment support for the Google Chrome browser. Note that Chrome support for addins is changing this year, and the new addin may not provide a long-term solution. A future maintenance release will provide support for the new Chrome browser. New Enhancements and Fixes in 8.10.1 (Hotfix #2) Following is a list of major defect fixes in PROXY Pro 8.10.1 (Hotfix #2):  Gateway Server and Host have compatibility fixes for the PROXY Pro Remote Desktop application for iOS. Customers using the iOS application in their environment are encouraged to upgrade to this release to avoid any issues.  New Host station name macros are introduced. These macros get values from Active Directory about the logged-in console user. The properties are: o %USERUPN% is the user principal name format of the console user, or blank if the user is not a domain account o %USERUPN+% is the same as above, but provides the “authorityusername” account name for local accounts. o %USERDISPLAY% is the user display name o %USERDISPLAY+% is the user account display name, or the account name in “authorityusername” format if the account display name is not set o %USEREMAIL% is the user account email address, or blank if the user is not a domain account
  • 10. 10 PROXY Pro 8.10.2 January 2015 o %USEREMAIL+% is the same as above, but provides the “authorityusername” account name if the email address is blank.  Web Console and Gateway Server now respect the X-Forwarded-For header on HTTPS (for Web Console) and WS/WSS (for Gateway Server) connections. In conjunction with the “trusted device list” setting in the Gateway Server, this allows the software to work well with reverse proxy servers like Microsoft Application Request Routing (ARR).  Master and Connection Window send entered keyboard input to Host promptly; previously, the keystrokes could be cached briefly, introducing delay in typing feedback.  Host did not send status reports to Gateways with which it had an active status reverse connection in v8.10.0 or later. This primarily affected the updating of the logged-in console user, or Host station name changes, and is fixed in this release.  Replaced OpenSSL library with version 1.0.1i, which is a security release of OpenSSL. Customers with internet-facing Gateway Servers listening for SSL connections are encouraged to upgrade to this release.  Web Console now marks cookies as “secure” and “httpOnly” (when possible) for increased security. All Web Console installations are encouraged to upgrade to this release. New Enhancements and Fixes in 8.10.1 (Hotfix #1) Following is a list of major defect fixes in PROXY Pro 8.10.1 (Hotfix #1):  Replaced OpenSSL library with version 1.0.1h, which includes fixes for newly found security vulnerabilities post the “Heartbleed” fix. Anyone with Gateway Server version 7.0.x through 8.10.1 should upgrade to PROXY Pro Gateway 8.10.1 (Hotfix #1), especially if Gateway Server is configured to listen for connections directly from the Internet. New Enhancements and Fixes in 8.10.1 Following is a list of major enhancements in PROXY Pro 8.10.1:  Explicit web proxy support: If a customer uses a web proxy server to manage internet traffic coming into or going out of its network, PROXY Pro applications that are outside the network (such as Host or Master) will be able to negotiate automatically with the web proxy to reach a Gateway server inside the network.  JSON file delivery mode: If Web Console is behind a firewall, the location of the JSON file for Host on Demand can be pre-configured, eliminating the need to make an additional HTTP request.  Host services enabled by default configuration option is now applicable only to Host on Demand. Default settings are available in the Web Console Settings > Host on Demand section of the Gateway tab in the Web Console.
  • 11. Release Notes PROXY Pro 8.10.2 11  Local network address exceptions: The Gateway server allows for one or more addresses or address ranges to be reclassified as external, even if they appear in the range of local network addresses.  Trusted Device list: If the Windows account user has any trusted devices, they can be added to list of machines that will be granted access to the Gateway server. New Enhancements and Fixes in 8.10.0 (Hotfix #1) Following is a list of major defect fixes in PROXY Pro 8.10.0 (Hotfix #1):  Replaced OpenSSL library with version 1.0.1g, which includes fix for the "Heartbleed" vulnerability. Anyone with Gateway Server version 7.0.x through 8.10.0 should upgrade to PROXY Pro Gateway 8.10.1 (Hotfix #1), especially if Gateway Server is configured to listen for connections directly from the Internet. New Enhancements and Fixes in 8.10.0 Following is a list of major enhancements in PROXY Pro 8.10.0:  View/edit Host services enabled at connection time: Host user will be able to specify which Host services to enable by default when Remote Desktop connections are established; if Permission to Connect is enabled, then Host user will be able to view/edit the list of Host services to enable for each Remote Desktop connection request.  Permission to Connect suppression option: If Permission to Connect is enabled, this new option will suppress the Permission to Connect requirement if the Host desktop is locked or waiting for logon  Toast notification for any active connections: When the Host user logs in, he/she will be presented with a list of any Account Users with active Remote Desktop connections to the Host in a toast popup notification window  Import/export Host settings in JSON format: Host settings can be exported to a text file in JavaScript Object Notation (JSON) format; Host settings can also be imported from a text file in JSON format.  Connect to Host settings options: New security options for accessing Host settings from the Host tray icon and the Host Control Panel itself allow for connection to the Host settings as different user.  Web Console database overflow protection: Unneeded data is now regularly purged from the SQL database.  More Host Grouping Rules: Additional grouping rules have been added to allow for more flexibility in creating custom collections of Hosts (see PROXY Pro Gateway Guide)  Peer-to-Peer Host Administration: Allows access to Host settings when Host is configured to accept connections through listed Gateways only. Particularly useful for certain operations involving the Deployment Tool. Following is a list of major defect fixes in PROXY Pro 8.10.0:
  • 12. 12 PROXY Pro 8.10.2 January 2015  Duplicate GUID protection. Duplicate Host GUIDs can occur when the HostPrep utility is not run on a Windows OS image containing PROXY Pro Host software prior to deployment. This condition resulted in unexpected behavior.  Host for Terminal Services Session Host process injection issue resolved. This was a regression from version 7 to version 8.0 and was seen only on Windows Server 2003. (Back-ported to 8.0.2 Hotfix #4). This allows for more robust compatibility with software like Citrix XenApp.
  • 13. Release Notes PROXY Pro 8.10.2 13 Additional Notes Note on Encryption Fix in 7.0.4 Connection encryption, which in some circumstances was found to be intermittent, has been fixed. Below is additional information about the defect, the circumstances in which the defect may affect performance, and mitigation options. Defect Description By default, connections between Proxy components (for example, Master-to- Host, Gateway-to-Host, Master-to-Gateway) use encryption (the current version is set by default to use the AES 256-bit cypher). We have determined that in certain circumstances, a defect in the encryption code occasionally causes encryption to be dropped, even though one or both Proxy components are configured to use encryption. This defect has been identified in Gateway and Workstation Editions of PROXY Pro versions 5.20.0 through 7.0.2. Defect Scenarios This defect can affect both peer-to-peer and Gateway-managed connections. There is no indication to the user when encryption is dropped (for example, the Lock icon will still show in the status bar of the Master, and Gateway Administrator will indicate encryption method being used in several places), nor is there any error message associated with this defect. However, the defect does not affect the following circumstances:  Does not affect SSL connections. With SSL protocol, encryption is explicitly enforced and is unaffected by this defect.  Does not affect reverse connections. Reverse connections are typically utilized when Host is outside the domain of the Gateway. Reverse connections allow Hosts to safely and seamlessly navigate NATs and firewalls and connect to a Gateway. This is arguably the most vulnerable connection type (since it can involve sending information over the public Internet) but it is not affected by this defect, i.e. encryption has been observed to be always in force.  The initial connection between Proxy components is not affected by this defect, so the very first service activity (e.g. remote viewing, recording playback) will not be affected. Mitigation Options Following are mitigation options for this defect:  No action. For most customers, the intermittent enforcement of encryption may not be a significant issue, and no action may be necessary:
  • 14. 14 PROXY Pro 8.10.2 January 2015 o Only peer-to-peer or Gateway-managed connections within the same domain are vulnerable to this defect, but most corporate domains are protected and considered safe environments. o Proxy data, while not encrypted, is encoded in a proprietary format and compressed, so intercepting and decoding that data would not be a casual challenge. Also note that this defect does not affect the initial connection between Proxy components. o The initial connection between Proxy components is not affected by this defect, so connections made to accomplish one and only one task will not be affected.  Upgrade to version 7.0.4. This maintenance release contains a fix for the root cause of the defect. The fix will enforce encryption when a 7.0.4 Proxy “client” (typically Master in peer-to-peer connections, or the Master connecting to a Gateway in the first half of a Gateway-managed connection, and the Gateway connecting to a Host in the second half) communicates with a 7.0.2 or older component. Customers should upgrade all Proxy components to 7.0.4 in order to ensure persistent enforcement of encryption on their connections. At a minimum, customers should upgrade Masters (and Gateways if present) to 7.0.4 to ensure encryption is enforced. Hosts can be a client in reverse connections but those are not affected by this defect. If a 7.0.2 or older Proxy client application tries to connect to a 7.0.4 Host, and encryption is requested but not enforced, the connection will be terminated and a new error code generated (0xC004DEAD).  Registry modification to existing Proxy components. For customers with Proxy components from version 6.0.2 through 7.0.2, a simple registry patch can be used to work around this defect. (Note: Customers with Proxy components from version 5.20.0 to 6.0.1 must either upgrade (at least the clients) to 7.0.4 or take no action.) As with the upgrade option, customers should apply the registry patch to all computers running Proxy software, but at a minimum, customers must apply the patch to Masters (and Gateways if present). Also note that customers must monitor deployment of new Masters and Gateways, and ensure that registry patch is applied if 7.0.4 (or later) software is not used. If a new Master or Gateway comes online and the patch is not applied, the defect may be active and will not be noticeable. o The registry setting for Windows x86 systems is: [HKEY_LOCAL_MACHINESOFTWAREFunk Software, Inc.Proxy v5Transport] "ShareSession"=dword:00000000 o The registry setting for Windows x64 systems is: [HKEY_LOCAL_MACHINESOFTWAREWow6432NodeFunk Software, Inc.Proxy v5Transport] "ShareSession"=dword:00000000 Following table summarizes the impact of different mitigation options: Table 1.

As a result, the following limitations may be observed:  If “%USER%” is in the station name, the name “Not-Logged-In” may be seen instead of the real user name.  The “User” column in the Gateway Administrator views should eventually get the correct user name, but this is not guaranteed.  We cannot impersonate the logged-in user, so end-to-end services like file transfer and remote management will not work if simple password authentication is used. Note that use of Windows Authentication is strongly recommended over simple password, especially in terminal services environments.  File transfer with Windows Authentication cannot evaluate the paths for the “Personal” and “Common” folder collections (which include “Desktop”, “My Documents”, “Shared Documents”, etc.). Users can navigate to these folders using their real paths, but the shortcuts do not appear in the file transfer user interface.
