Hi all im running suse 10 on 3 computers,the problem is this i have only just installed suse and when i ssh from my laptop to a second computer called compaq i get this error message.
"master@laptop:~> ssh master2@compaq
buffer_get_ret: trying to get more bytes 4 than in buffer 0
buffer_get_int: buffer error
master@laptop:~>

I only got this message after changing my ip address on compaq so i am guessing this error is some kind of authetication problem.Now after doing some reading i believe there is a file called "known_hosts" which could be the problem.
I can still ssh from compaq to my laptop,i just can not ssh from laptop to compaq.Thanks Nige

ok i changed my ip back to what it was and now i can ssh from my laptop to compaq,but only as root.If i try to ssh in to a user as in the example above i get the same error message.nd just for the record i found that file here. "~/.ssh/known_hosts"
Anyway i can ping from my laptop the username on compaq so i guess that rules out dns issue.Ill have another look in the ssd_config see if tere is something there.
THanks Nige.

It would seem i was so close yet so far away all i had to do was clear the file "~/.ssh/known_hosts" and everything was ok.

You might want to look into securing your SSH server. Never good practice to allow remote login to a Linux server as ROOT. That is why they have the Substitute User (SU) and SUDO commands.

Linux can be just as vulnerable as Windows if you don't take precautions to harden your system security!
