The ettercap project's CVS data is in read-only mode, so the project may have switched over to another source-code-management system. To check, visit the Project Summary Page for ettercap and see if the menubar lists a newer code repository, such as SVN or Git.

The CVS data can be accessed as follows. You can run a per-module CVS checkout via pserver protocol:

cvs -z3 -d:pserver:anonymous@a.cvs.sourceforge.net:/cvsroot/ettercap co -P ettercap

cvs -z3 -d:pserver:anonymous@a.cvs.sourceforge.net:/cvsroot/ettercap co -P ettercap_ng

You can view a list of files or copy all the CVS repository data via rsync (the 1st command lists the files, the 2nd copies):

rsync -a a.cvs.sourceforge.net::cvsroot/ettercap/

rsync -ai a.cvs.sourceforge.net::cvsroot/ettercap/ /my/local/dest/dir/

If you are a project admin for ettercap, you can request that this page redirect to another repo on your project by submitting a support request.
