No CVS working, despite of SSH connection

[Ralf Junge]

Hi,

we have a big problem. On a new server we installed a cvs and want to 
connect to our repository.
We can connect to the repository from other servers.
CVS root (CVSROOT) and connection method (CVS_RSH) is already set correct.
We can also connect to the repository from the new server via ssh, but 
all cvs commands are out of work and return the following error message:

cannot get working directory: No such file or directory

Has anybody any ideas?

Greetings

Ralf
