just FYI in case you run into the same problem:
From the SF site status page:
( 2008-03-07 05:25:00 - Project CVS Service, Project Shell Service,
Project Subversion (SVN) Service, SourceForge.net Web Site ) On
2008-03-06, during a routine security audit, SourceForge.net staff
identified a deficiency in systems data control. We are unaware of any
exploitation of this data, which was present in encrypted form. In
addition to removing the data, as a preventative measure we have also
forced password changes for all SourceForge.net user accounts.
so if you have trouble using the developer cvs access, going to the SF
site and changing you password might help (if you are using ssh keys
this probably won't affect you until you start setting up a new machine
for an out-of-house demo ;) ).
