[cvsnt] error when access cvsnt from linux

[zhousp]

hi,all

I set up a cvsnt box on windows 2003 as server,then I want access my server
from linux:

[root at redflag bin]# cvs -d :pserver:ansi at 192.168.0.226:e:/cvsroot login
cvs login: CVSROOT may only specify a positive, non-zero, integer port (not `e:').
cvs login: Perhaps you entered a relative pathname?
cvs [login aborted]: Bad CVSROOT: `:pserver:ansi at 192.168.0.226:e:/cvsroot'.

How can I access cvsnt from linux?

many thanks.
