ssh server close connection after password attempt - ssh

Question

I am trying to access to remote server via ssh. I couldn't do it via ssh command in CLI, but with same credentials I can access via putty ssh.
I am using ubuntu 12.04.
I don't have access to ssh server, so I can't change sshd config file.
Access to ssh server is possible form other machines via ssh CLI command, but from my mashine this is not working. Credentials are proper because I can connect via putty, and I don't get any message from server when I enter password. It just close connection.
command i use to connect via ssh in CLI is:
ssh -vv someuser#somehost.com
This is output:

Answer 1

First you can try with ssh -o GSSAPIAuthentication=no someuser#somehost.com ; it should make the Unspecified GSS failure messages disappear.
Then, if you are able to connect with putty, you can connect and then run sshd in debug mode on a higher port (you do not need to be root to do that, but you need no firewall blocking all the ports) :
/usr/sbin/sshd -d -e -p1234
and then you can try to connect in CLI with
ssh -p 1234 someuser#somehost.com
and you will see, in your putty session, the reason why the server closes the connection.

Answer 2

Check /etc/ssh/sshd_config for one of the following,
LoginGraceTime and make sure that is set to a time limit that you can enter your password. Otherwise it will close the connection if your request doesn't get authenticated within the timeframe. (example: this will give you a 1min window, LoginGraceTime 60)
"UseDNS no" will make sure sshd would not try to resolve the hostname. If the ssh client computer and the server are using two different nameservers and they point to different IPs for the same hostname might end up locking you out. So "UseDNS no" would resolve such problems.
"PasswordAuthentication yes" will make sure the SSHd accepts user entered passwords.
That's all I have come across for this issue.
