Re: Tunneling

martin, I think we've done something similar when we were (well, you 
still are) connecting to netbeans.org from sun network.
we used a java ssh tunneling application which was listening on the 
local machine on the cvs port (4201), our cvs connected to local machine 
using the pserver access method, but it was tunneled by the ssh app 
through the http proxies or something (i'm on shaky ground here, not 
intranet/firewall expert) and connected to the cvs port on the 
netbeans.org server.
Is that what you intend to do, Jim?

in this scenario, on the client side the cvs library was used as is, 
only with different cvs root. (eg. :pserver:mkleint@localhost:/cvs 
instead of :pserver:[email protected]:/cvs)
the hard part prolly setting up the server to allow tunneling, set up 
the proxies and all the rest of the firewall bussiness I have no clue 
about.. :)
