- 1. Beginning Custom Projects with Raspberry Pi Connecting with SSH
- 2. 64 Connecting with SSH ▪ Secure Shell (SSH) ▪ Shell = “command line interpreter” ▪ Secure, because it is encrypted ▪ SSH establishes encrypted tunnel to a remote shell ▪ Requires SSH server to be running on Raspberry Pi ▪ Requires client on your local computer ▪ SSH server is disabled by default
- 3. 65 Enabling First-Boot SSH Server ▪ For added security, SSH is disabled ▪ Must tell Raspberry Pi to enable it ▪ microSD has two partitions “boot” (small partition) “root” (large partition) ▪ Raspberry Pi OS looks for any file called “ssh” in boot partition. Enables SSH server, deletes the file
- 4. 66 Enabling First-Boot SSH Server ▪ Add file “ssh” to boot partition ▪ Reinstall in Raspberry Pi ▪ Power on ▪ Verify networking with ping ▪ Connect with SSH ▪ run raspi-config to enable SSH server
- 5. 68 SSH Clients ▪ Linux and MacOS native SSH client in terminal ▪ Windows Putty https://putty.org to download
- 6. 70 Summary ▪ Enable SSH server on first-time boot Any file named “ssh” in boot partition ▪ Retrieve IP from router DHCP logs ▪ Connect with SSH client ▪ First SSH session requires verifying encryption key ▪ Permanently enable SSH server using raspi-config
