[cvsnt] History logging is not enabled on this repository

[Sabahat Adil]

Hi All,
I can't take commercial support coz i am learning CVS for myself.
I spend extra time for learning cvs.
I am running below command but following error is coming
cvs -d:sspi:test90:/myrepo history -z -0844

***** CVS exited normally with code 1 *****

cvs [server aborted]: History logging is not enabled on this repository
Regards,
