SSH error: end of file from server

[Andrew Wood]

Any idea why I cant access a repository to checkout a project remotely,
but I can on the local machine.
I'm trying to do it with CVS on Mac OS X which is installed by default,
along with OpenSSH. I'm also trying it with TortoiseCVS on Windows, which
I beleive includes i'ts own SSH client (a copy of PuTTY?).

The server is running the latest version of CVS on Linux. I can SSH into
the server and get a shell, and do anything, including checking out the
project into my home dir on the server, but trying to do it from another
machine (OS X) gives the following error:

Operation timed out
cvs [checkout aborted]: end of file from server (consult above messages if
any)

The command I'm using is:

cvs -d :ext:address@hidden:/cvsroot checkout test2

On Windows, I get a different error:

Cannot open CVS/Entries for reading. No such file or directory

I've looked through the archives and a couple of people seem to have had a
similar problem but I couldnt find a real solid solution, other than a
hint that SSH isn't connecting, which would fit seeing as it isn't
prompting for a password (on OS X), yet on Windows it does :S
Thanks
