Had I found something I understood there I would not have posted.

I have a remote shell account that I can use as the gateway and in
fact have been able to successfully set that up for http:

  ssh -L 8080:www.google.com:80 some.host.com <==remote shell account

When I run the command it logs me into my remote shell account

Then from a different xterm:
lynx localhost:8080 connects to google thru my remote shell account.

For gnus I tried:
ssh -L 5119:news.gmane.org:119 some.host.com

However when I attempt that with gnus, I'm told:
  >>> (error localhost:5119/nntp node name or service name not known)
  nntp (localhost:5119) open error: '>>> (error localhost:5119/nntp
  node name or service name not known)'

I wasn't sure what to put in gnus but I vaguely remember doing
something like:
   (setq gnus-select-method '(nntp "localhost:5119"))

But that is what got the error above.

Telnet can see localhost 5119 and show new.gmane.org is there.

So maybe its just a matter of getting the right syntax in gnus.
