We provide CVSup, CVSync, and AnonCVS access to the OpenBSD source repositories. The collections are updated every 3 hours from the main repository in Canada. This machine is hosted in Nürnberg, Germany and maintained by Armin Wolfermann. It is also known as anoncvs2.de.openbsd.org, cvsync2.de.openbsd.org and cvsup2.de.openbsd.org.
As of 2009-09-03 the OpenBSD-all CVSup collection includes OpenBSD-xenocara. Please take a look at your CVSup configuration file if you still have enabled both of them (and disable OpenBSD-xenocara).
CVSup configuration files: getting the CVS repository or getting the checked out sources
CVSync configuration file: getting the CVS repository
Anoncvs usage: cvs -e ssh -d anoncvs@mirror.osn.de:/cvs get src
