Code:
The file in /etc/xinetd.d/cvs is
# default: off
# description: The CVS service can record the history of your source \
# files. CVS stores all the versions of a file in a single \
# file in a clever way that only stores the differences \
# between versions.
I think the file should be named /etc/xinetd.d/cvspserver not cvs.
CVSROOT ?? make sure to set it properly. My server is up with both pserver and ext methods.
