- 5. Born on December 1998 IPv6 is a new layer 3 protocol which will supersede IPv4 Formerly called as SIP, SIPP Major changes in IPv6 are the redesign of the header, including the increase of address size from 32 bits to 128 bits IPv6 – A Quick Tour
- 6. IPv6 Features Increased address space 128 bits = 340 trillion trillion trillion addresses (2 128 = 340,282,366,920,938,463,463,374,607,431,768,211,456) = 67 billion billion addresses per cm 2 of the planet surface Hierarchical address architecture Improved address aggregation More efficient header architecture Neighbor discovery and autoconfiguration Improved operational efficiency Easier network changes and renumbering Simpler network applications (Mobile IP) Integrated security features
- 7. IPv6 Addresses Example 3ffe:3700:0200:00ff:0000:0000:0000:0001 This can be written as 3ffe:3700:200:ff:0:0:0:1 or 3ffe:3700:200:ff::1
- 8. 0 bits 31 Ver IHL Total Length Identifier Flags Fragment Offset 32 bit Source Address 32 bit Destination Address 4 8 24 16 Service Type Options and Padding Time to Live Header Checksum Protocol Existing System - IPv4 Header Removed Changed
- 9. 0 31 Version Class Flow Label Payload Length Next Header Hop Limit 128 bit Source Address 128 bit Destination Address 4 12 24 16 Proposed System -IPv6 Header
- 10. Supported RFCs for our project RFC1886: DNS extension for IPv6 RFC2373: IPv6 addressing architecture RFC2428: FTP extensions for IPv6 & NATs RFC2452: IPv6 MIB: TCP RFC2463: ICMP for IPv6 RFC2464: IPv6 over ethernet RFC2466: IPv6 MIB: ICMP RFC2553: Basic socket API for IPv6

- 12. Our Project Scheduled Module 1 Study about Linux. Kernel Compilation and Creation of Batch Work. Module 2 Study about DNS And BIND. DNS Configuration Settings. Module 3 Sockets for connection between IPv4 and IPv6. Construction of java code with Swing and testing. Our Discussion
- 13. Topics of Discussion Introduction Project Scheduled About Kernel Compilation About DNS Configuration Conclusion
- 14. Why Compile a Kernel? Optimization "Lower" memory footprint Speed, compiled for your hardware Additional drivers Enabling additional features (security patch for example) Use a more recent kernel than prebuilt kernels (for example, an RC version)
- 15. Obtaining and Extracting the Kernel Download the source from: http://www.kernel.org/pub http://carroll.aset.psu.edu/pub/linux/kernel Extracting the sources cd /usr/src; tar xvfj linux-kernel-2.4.2.tar.bz2
- 18. Building the Kernel Kernel # make dep -> dependency check # make clean -> parameter check # make bzImage -> Extracting Kernel image Modules # make modules -> configuring modules # make modules_install -> installing modules
- 19. Installing the Kernel New kernel is in arch/i386/boot, copy it somewhere (i.e. /boot/vmlinux-KENRELVERSION) Copy System.map to /boot/System.map-KERNELVERSION ln -s /boot/System.map-KERNELVERSION /boot/System.map GRUB: Add to /boot/grub/menu.lst title RedHat Linux Enterprise 3 GNU/Linux, kernel 2.4.8 root (hd0,0) kernel /boot/vmlinuz-2.6.8 root=/dev/hda1 ro

- 29. DNS in Nut Shell DNS is the Domain Name System It translates (or "maps" as the jargon would have it) from name to address and from address to name, and some other things. Allow machines to be logically grouped by name Domains Provides email routing Information Forward Lookup Hostname into IP address Reverse Lookup IP address into Host Name
- 30. DNS Server Functions Internet Domain Support - Accessing servers through remote network Local Name Resolution - Resolve the hostnames of systems on your LAN Internet Name Resolution - Most often used for this is the ISP's DNS servers
- 31. Graphical Representation DNS Configuration
- 32. Name Server Hierarchy Master Name Server Contains the master copy of data for a zone. Slave Name Server Provides a backup to the master name server. Caching Name Server Provides a backup of queries and answers
- 33. DNS upside-down tree structure
- 34. Service Profile :DNS Type : System V-Managed Service Packages : bind, bind-utils Daemons : named, rndc Script : named Ports : 53(domain), 953(rndc) Configs : /etc/named.conf, /var/named/* /etc/rndc.*
- 35. DNS Startup # Service named start - Starting the named service # Service named stop - Stoping the named service # Service named restart - Restarting the named service # Chkconfig named on - Starting at the time of boot
- 36. Configuring BIND BIND –Berkeley Internet Name Domain Widely used DNS server on the Internet Red Hat Enterprise Linux uses BIND 9 Maintained by ISC( Internet Software Consortium) Default Configuration file in BIND is /etc/named.conf
- 37. DNS TOOLS Debugging tools named-checkconf, named-checkzone DNS lookup tools nslookup dig
