After the great disk crash, sourceforge changed all the project names. In each case you need to start over (i.e. recheckout) the project with the project name at the start. In snd it's: cvs -d:pserver:anonymous@snd.cvs.sourceforge.net:/cvsroot/snd login cvs -z3 -d:pserver:anonymous@snd.cvs.sourceforge.net:/cvsroot/snd co cvs-snd
