I don't know if cvs itself supports a proxy, but CVS_RSH can point to a
program that supports a proxy.  You just have to make sure the connection is
8-bit clean.  (If it is not 8-bit clean you will run into what seems to be
random errors.)  For example, if you wish to use cvs with 'ssh' you would
point it to a script like:

$ echo '#!/bin/bash' >ssh-noescape
$ echo 'exec ssh -T -e none "$@"' >> ssh-noescape
$ chmod ugo+x ssh-noescape
$ export CVS_RSH=`pwd`/ssh-noescape
$ cvs -z3 -d:ext:username AT hostname:pathname checkout modulename

I used 'ssh' in this example, because many companies now days are leaving
port 22 as an open port to connect outside their firewalls.

I'm actually quite surprised, there does't seem to be an "open source"
version of sock5.  So if you need proxy tools to connect you might need to
hop through another machine in your internal network which has the proxy
tools installed.  i.e.

$ echo '#!/bin/bash' > proxy-ssh-noescape
$ echo 'exec ssh -T -e none unixhost prsh "$@"' >> proxy-ssh-noescape

where unixhost is the name of a machine with a utility like "prsh".  i.e.
rsh compiled with sock5 support.

Yet another option is you download something like connect.exe and use it to
connect the remote port to a local port.  i.e.

    connect.exe -p 22022 -S user AT foo DOT com hostname 22

Then you would use a command like:

$ echo '#!/bin/bash' >ssh-noescape-connect
$ echo 'exec ssh -p 22022 -T -e none "$@"' >> ssh-noescape-connect
$ chmod ugo+x ssh-noescape-connect
$ export CVS_RSH=`pwd`/ssh-noescape-connect
$ cvs -z3 -d:ext:username AT hostname:pathname checkout modulename
$ export CVS_RSH=`pwd`/ssh-noescape-connect
$ cvs -z3 -d:ext:username AT localhost:pathname checkout modulename

                                         Bill
