Re: [PLUG] Puzzling openssh problem

Thank you, you're right: the 127.0.1.1 is puzzling and I have no idea where it's coming from, because ip addr show clearly shows the IP address as 127.0.0.1. I may have to go in myself tomorrow to try to figure it out (right now one of our developers is in the office and I'm working remotely).

I have a really puzzling problem now in that ssh localhost does not work (it says Connection closed by 127.0.1.1 port 22)

Is localhost defined in your ~/.ssh/config file?   I’m surprised your localhost would be defined as 127.0.1.1. 

Also, your ssh_config file may not allow you to open IPv6 connections, whereas telnet clearly does. 

Finally, check iptables rules for IPv4 localhost port 22.
