CVS And Solaris

[Steve P]

First of all, I would like to thank Mr. Knowles for his fine help with my
previous post.  I wish there was a way I could rate it.

Here's another scenario I need some help with:  At school, we have a Solaris
machine we do all of our schoolwork on, and, of course, it has CVS.  If I'm
at school (or communicating via SSH), I can check in / check out projects
from my cvs root on the Solaris machine to my Solaris account.

Here is where the problem comes in.  I have WinCVS set up here at home and I
want to be able to do the same thing.  I have SSH set up here and I use
WinCVS to communicate with a linux machine.  Again, no problems.  However,
when I try to use WinCVS to communicate with the Solaris machine, I get the
following error:  cvs [checkout aborted]: end of file encountered.  The
settings are the same for the Linux machine and the Solaris machine (of
course, the paths, etc. are different), but I still cannot access my
repository on Solaris.  If I do the following:

     ssh -l username host 'cvs'    I get a "cvs:  command not found"

        but, if I do the following:

     ssh -l username host 'ls'    I get a list of my files.  This tells me
SSH is working correctly.

     My question:  Has anyone encountered anything like this before?  Is
there a way for the Solaris admin to disallow this kind of file transefers
from one machine to another (in other words, turn off "cvs" from external
machines)?  Is there a way to check?

     Thank you very much in advanced,

     Steve
