Hi,
Something happened and I can't log in via ssh anymore:
I haven't done any changes to ssh config recently, I used to log in using pub_key auth method everyday. I don't have physical access to machine and I have root password.
I believe that I can manage to reestablish connection using currently existing ssh socks tunnel:
This tunnel has been opened couple of hours ago hour later I couldn't connect via ssh anymore.
Things I've already tried:
I really believe that I can do something with this ssh socks connection (which is still alive). Do you, guys, have any idea how to inject commands to be executed on this remote host via ssh socket?
I was thinking about netcat and -e flag, but it seems that BSD version of netcat does not work as i expected.
Regards
Dud

I believe that I can manage to reestablish connection using currently existing ssh socks tunnel:
Code:
ssh -qTfnN -D 7070 -C login@hostname
Things I've already tried:
- logging in using password method
- logging in from different hosts
- logging in from different ips
