fd.o's CVS migration is finally complete. CVS has moved from gabe.freedesktop.org (formerly 'the freedesktop.org machine') to kemper.freedesktop.org, a new secure host. Anonymouse CVS and ViewCVS now run on annarchy.freedesktop.org.

This means that, technically, you should now be committing to:
username@cvs.freedesktop.org:/cvs/reponame
and checking out anonymously from:
:pserver:anoncvs@anoncvs.freedesktop.org:/cvs/reponame

Anything using '@freedesktop.org' or '@pdx.freedesktop.org' is incorrect and may, at some point in the future, stop working. Anything using '@cvs.freedesktop.org' is incorrect, but will probably keep working for the time being. The canonical URL for ViewCVS is now http://webcvs.freedesktop.org; cvs.freedesktop.org will probably keep issuing 302s, but that too may disappear at some point in the future, so update your URLs.

Some code has moved to GIT, too. I can't remember exactly what the process for committing there is, but the process for checking out is:
git-clone git://anongit.freedesktop.org/modulename

The pserver redirection to anoncvs.fd.o wasn't working for a while. I'll post what I did, and see if you can figure out why:
root@kemper:~% iptables -t nat -A PREROUTING -d kemper.freedesktop.org -p tcp --dport cvspserver -j DNAT --to-dest 131.252.208.36:2401
