[twill] twill Digest, Vol 8, Issue 14

[John Mudd]

Thanks!  VNC works much better than ssh alone.

The only stumbling block is that the remote Linux box has all but port
22 (ssh) blocked.  So running vncviewer at home couldn't access the
port (5901) published by the remote vncserver.  But it's easy to
forward the remote port home with the following command.

    ssh -2 -n -R 2024:localhost:5901 -N <my home IP addr>

I chose port 2024 arbitrarily.  Now I can connect from home using the following.

    vncviewer localhost:2024

It works great.  This remote Linux box only gives me about 30 KB/sec
net access but now that I'm using VNC I have a Linux desktop that
works well.  Now I can try Firefox and Seleniun-IDE.

John
