To check which version of OpenSSH the Palo Alto Networks firewall PAN-OS is running, make a telnet session to the firewall’s management interface on port 22, which will simulate a SSH session. The firewall will close the session and will reply with a connection status message that includes OpenSSH version used.
Here is an example:
dragoslav@dragoslav:~$ telnet 10.193.80.51 22 Trying 10.193.80.51... Connected to 10.193.80.51. Escape character is '^]'. SSH-2.0-OpenSSH_11.1 Connection closed by foreign host.
In this example, the Palo Alto Networks firewall is using OpenSSH version 11.1.
