[SOLVED] ssh connection closed immediately after logged in

gqqnbig · 07-02-2011, 02:50 AM

I'm using Ubuntu 11.04. I've bought an account in a SSH sever.

Code:

loveright 02:41:54 ~$ ssh gqqnb@205.185.123.107
gqqnb@205.185.123.107's password:
Last login: Sat Jul  2 14:41:53 2011 from 123.137.120.69
Connection to 205.185.123.107 closed.

I've tried many times, the issue persists. ssh localhost is ok.

I go to Windows, run Bitvise Tunnelier. After providing corresponding information, connection is established.

Code:

So, how can I fix? Any hints?

Try first a verbose connection :

Code:

ssh -vvv gqqnb@205.185.123.107

It's fixed now.
I contracted the custom service, he said it was because of the configuration of the server. He fixed it and I can log in successfully.

Hi
try to debug. Type ssh -vvv gqqnb@205.185.123.107 and check what difference in output
from Bitvise Tunnelier.
