Getting pgsnmpd using rsync/sup

I checkout the pgsnmpd using command
"cvs -d pserver:anonymous@cvs.pgfoundry.org:/cvsroot/pgsnmpd checkout -r REL1_0 pgsnmpd"

Now, I want to setup the local mirror and wants to checkout the sources from there. I use the following command:

$rsync -av cvs.pgfoundry.org:/cvsroot/pgsnmpd/* .
Password:

But, it asks me for password. What password should I enter?

$ rsync -av cvs.pgfoundry.org::
pgfoundry          Mirror: ftp.postresql.org
pgfoundry_all      Backup: tribble.postresql.org
pgfoundry-cvs      pgFoundry CVS
pgfoundry-files    pgFoundry files

Please help. Thanks.

Sandeep.
