When I try to tunnel my traffic from my one system to another I get an ssh error and the connection breaks. But if I simply connect to my ssh server the connection works fine.
On googling I found people saying that deleting the "known_hosts" file in .ssh directory can fix it (because of corruption due to newline character). But it also didn't work.

I tried to do the same in BT5, BT5r2, BT5r3 and I m facing the same problem in all of them.
Anyone else facing the same problem?
Re: SSH Error
My experience says it's the ~/.ssh/authorized_keys file, not known_hosts. Try moving it elsewhere or deleting it entirely.
Re: SSH Error
Thank you. But there is no such file in my .ssh directory.
Re: SSH Error
The problem was with the SSH server. I was using freesshd. I replaced it with winsshd and it worked perfectly.
