cannot mkdir /tmp/cvs-servpid

[address@hidden]

Hello all,

I have been using for a while now (at least for the past year) cvs
through ssh. My install is the following:

A WinXP home pc running cygwin and the following 'cygwin apps' : ssh
and cvs. I have a cvs repository sitting on that PC.

I am connecting from a work pc (running WinXP as well) via ssh to the
home pc with passauthentication set to no and this ssh connection works
fine. I have configured cvs (for that I have set the CVS_RSH and the
proper CVSROOT) on the work pc so as to access the repository sitting
on the home PC. For the past year, everything went fine and worked
correctly.

Recently I had to re-install WinXP on my home pc. I have re-installed
cygwin on this home pc, did all the necessary configuration at ssh and
cvs layers but I can no longer do any cvs operation (checkout, update,
etc. do not work) but ssh still works fine as before. I have
cross-checked every possible configuration and version details on both
PCs. Even from the home pc, I have tried to connect via ssh to the
repository (CVS_RSH=/bin/ssh and
CVSROOT=:ext:address@hidden:/cygdrive/c/arcroot ) but I am getting the
same error.

The error message is
cannot mkdir /tmp/cvs-serv2916/.
No such file or directory

I have run cvs commands with the global -t option and nothing
particular seems to be displayed.
 -> main loop with
CVSROOT=:ext:address@hidden:/cygdrive/c/home/arcroot23qld1j
 -> safe_location( where=(null) )
 -> Starting server: /bin/ssh -l teggy localhost cvs server
S-> my_module (backup, Updating, , )
cannot mkdir /tmp/cvs-serv2916/.
No such file or directory
 -> Lock_Cleanup()
 -> Lock_Cleanup()

What puzzles me is that cvs is trying to mkdir /tmp/cvs-serv2916/. and
indeed this command with the trailing /. cannot work ("mkdir
/tmp/cvs-serv2916" works but "mkdir /tmp/cvs-serv2916/." does not work)

Has anyone come across this problem ?

The latest cvs version downloaded via cygwin setup is 1.11.21 ...

Please helppp !!!!!! I'm now short of hints to try :)
