Have this problem on several servers we run. I can ssh to a remote servers IPv4 address successfully on the default port 22 and any other port I change the remote servers ssh port to.
I can successfully ssh to the remote servers IPv6 address but only if its on port 22, if I change the ssh port on the remote server to another port, restart sshd, then try to connect the connection hangs before timing out. No error messages. Disabling the firewall makes no difference.
I am of course using the p switch eg: ssh -pxxx [email protected] address.
Also tried with ssh -6 -pxxx [email protected] address.
Any ideas what up?
