    ok...I can ssh into a solaris 10 box. From this solaris box, I can ssh into my work desktop (ubuntu 5.10). I can run freenx on my work desktop, but not on the solaris box. Is there any way of tunneling / proxying through the solaris box directly to the ubuntu box? x forwarding isn't really an option as I only have a dsl connection.

    AFAIK, only port 22 on the solaris box is open,externally and access is controlled by external IP.

    Do we have a sticky on Tunnelling etc as per Khannie's title?

    Would find it useful if all the NIX heads could stick up suggetsions / howtos or point in the general direction of good info sources on same.

    Sorry for the hijack (oops the Brits will probably be after me now) Khannie.

    I think thats why no-one is answering. A workaround would probably mean putting daemons on the sun box and possibly the other box to route the traffic via an ssh connection. :eek: Very haxy stuff.

    I don't know much about FreeNX, but I'm going to assume that it listens on a single, fixed port number on your work PC, let's say 1234. If so, ssh has a port-forwarding option -L you can use, which opens a (listening) port on the local PC. When a connection is made to this port it's forwarded to the requested destination host and port. So, something like: 
    ssh -L 5678:ubuntupcname:1234 username@solarisbox
    should work. You can then point your FreeNX client at localhost:5678 and ssh will pass that on to port 1234 of the ubuntu PC.

    Wouldnt a VPN be a better option for multiple machine access?

    SSh tunnel forwarding is the only way im aware of to do this. How would DSL rule this out?

    That is fantastic! I must remember to use this one.
