[Pavel Stehule]

Hello, I have a problems still :-(

on local connect cvs works well

export CVSROOT=:local:/usr/local/cvs:
/usr/local/bin/cvs ls
Listing modules on server

CVSROOT
test


[root at stehule CVSROOT]# cat /usr/local/cvs/CVSROOT/admin
root
stehule

Maybe I have wrong CSVROOT
[root at stehule CVSROOT]# /usr/local/bin/cvs login
Logging in to :pserver:stehule at localhost:2401:/usr/local/cvs/
CVS password:
cvs [login aborted]: No valid repository roots defined.  Aborting.

What is wrong? CVSROOT?
