Re: [PLUG] Puzzling openssh problem

[Michael Lazin via plug <plug@lists.phillylinux.org>]

I was curious about 127.0.1.1 and so I looked it up and that address exists as localhost on debian systems only.  See https://serverfault.com/questions/363095/why-does-my-hostname-appear-with-the-address-127-0-1-1-rather-than-127-0-0-1-in

I have two possible suggestions which may get you moving in the right direction.  One is try this again and then look at your syslog.  The other is to set the flag for verbose ssh.  I am on my phone right now so I am working from memory but I believe you want ssh -vv but you might want to check the man page because it has been a long time since I have used verbose ssh to troubleshoot an issue and I am going from memory.  I hope that this helps.   Thanks,

On a Debian Stable system, I installed (via pinning) golang and clang from Testing which together brought in a bunch of new packages. 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), but telnet localhost 22 says:

Trying ::1...

Connected to localhost.

Escape character is '^]'

SSH-2.0-OpenSSH_7.9p1 Debian-10+deb10u2

(and after a while, the daemon closes the connection)

Any ideas as to what could be wrong? I am not even sure where to look. Thank you.
