ssh problems

[sniker]

I've got a server that running knoppix hdinstall, It works fine, no problems, but when I'm trying to connect to it with ssh from school I've got this "error" messege:

ssh_exchange_identification: Connection closed by remote host

I can use ssh everywhere else, but not at school. My school have not blocked port 22, I know that becouse I've got many friends at the same school who has servers runnings at their homes, and i works fine to connect via ssh to their servers.

Any suggestion?

(sorry for bad English)

sniker, you need to do more fault finding. Can you ssh to your server from itself? What about from a box on the same local LAN? What ssh programs/versions are you using on each side? (there have been ssh incompatabilities historically). Try to upgrade your ssh client (putty?) and server (openssh?) to the latest same versions. Capture your ssh -vv output and post to a more appropriate forum than this, e.g. comp.security.ssh. Sorry I can't help better but there is not enough information and I don't know ssh well enough to guess from that fragment of error message.
