I can't ssh from any machine to one of our servers (in the same network). I try to run ssh in verbose mode but do not get any error :
vincent@feed01:/var/cache/feed$ ssh -vvv email@example.com OpenSSH_5.9p1 Debian-5ubuntu1.1, OpenSSL 1.0.1 14 Mar 2012 debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to feed02.xxx.com [192.168.0.161] port 22. debug1: Connection established. debug1: identity file /home/vincent/.ssh/id_rsa type -1 debug1: identity file /home/vincent/.ssh/id_rsa-cert type -1 debug1: identity file /home/vincent/.ssh/id_dsa type -1 debug1: identity file /home/vincent/.ssh/id_dsa-cert type -1 debug1: identity file /home/vincent/.ssh/id_ecdsa type -1 debug1: identity file /home/vincent/.ssh/id_ecdsa-cert type -1
And from that moment nothing happens, I have to Ctrl-C to regain access to the terminal.
auth.log doesn't capture anything either.
We have tried from different machines, different users, same issue.
iptables -L INPUT -v -n | less
What could be the issue ?
