OpenSSH has the ProxyJump command (and its corresponding argument: -J): `ssh -J user1@proxy1,user2@proxy2 targetuser@targethost` Or in `~/.ssh/config`: ``` Host targethost ProxyJump user1@proxy1,user2@proxy2 ``` Then you just interact with `targethost` as if it was local. http://man.openbsd.org/ssh_config#ProxyJump Older OpenSSH versions can utilise `ProxyCommand` with `nc` or `netcat`. ``` Host targethost ProxyCommand ssh -q user2@proxy2 nc targethost 22 Host proxy2 ProxyCommand ssh -q user1@proxy1 nc proxy2 22 ``` http://man.openbsd.org/ssh_config#ProxyCommand If you're using something other than OpenSSH, investigate the equivalent settings in your SSH client implementation. -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere. ___________________________________________________________________________ Sent via: Wireshark-users mailing list <wireshark-users () wireshark org> Archives: https://www.wireshark.org/lists/wireshark-users Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org?subject=unsubscribe
