If you cannot get the admin of the firewall to open up port 5999 how about
port 21 for ssh. It seems that most people have that open anyway so it may
not be much of an issue.
Here's where I am going.
1) You need to get shell access on a remote machine outside the firewall.
This shouldn't be too hard, either your machine at home, a friends machine
or one of those many that are offering free shell access. We'll call it
2) From your FreeBSD machine behind the firewall you would open up a
tunnel between yourself and the friendly machine on port 5999 for cvsup.
$ ssh -L 5999:cvsupmirror.freebsd.org:5999 loginid at friendly.excample.com
replace "cvsupmirros.freebsd.org" with an actual one from the list of
mirrors. loginid is your login name on the remote machine.
3) From another command prompt you run cvsup while pointing to your
localhost as the cvsup server.
# cvsup -g -L2 -h localhost /path/to/cvsupfile
Cheers and good luck,
