The instructions at http://www.ca.postgresql.org/devel-corner/docs/postgres/cvs.html#ANONCVS do not work.
pgtest@dugite pgtest$ cvs -d :pserver:anoncvs@postgresql.org:/home/projects/pgsql/cvsroot login
(Logging in to anoncvs@postgresql.org)
CVS password:
cvs login: authorization failed: server postgresql.org rejected access to /home/projects/pgsql/cvsroot for user anoncvs
pgtest@dugite pgtest$
I produced the above error by cutting and pasting.
My cvs update (which was working) hasn't worked for some days.
