would do what has been suggested to you already ... format and re-install .... seriously (restore from a CLEAN backup) the last part there is tremendously important ...

Thanks a lot to all of you for your responses.
I have just rebooted my local box and 2 days after that,
it doesn't attempt any attempt to ssh the remote box.
After then it again has started to log into the remoet
box with the right users and with a pubkey. Actually I
loginto the remote box with pubkey and somehow the hidden
process learn that !!!

I really don't know how to stop this :-(

Maybe it's not a hidden process? Have you checked last logon records? Any
unauthorized logon? See anything interesting with netstat -anop ?
