Re: [PLUG] Question about Remote Desktop through a NAT
|
I've actually been thinking about this recently too - its pretty
straightforward to set up nicely - setting it up will most likely require
you having ssh access to his machine, so set it up when hes directly
plugged into the modem:
-get a dyndns account on *your* internet connection, and forward port 22
somewhere useful
-create a passwordless SSH key on his machine, so ssh from his machine to
yours works sans interaction
-still on his machine, in ssh_config, set it up so that an ssh session from
his machine to yours uses the -R flag to reverse port forward 590* from your
machine, across the tunnel to his. This will enable you to sit at the
machine that has been ssh'd *to*, and vnc to localhost, which will be
forwarded to his machine regardless of what his private IP is.
It should take a little legwork to set up initially, but should do the
trick. To take it one step further - I know on macs you can create .term
files, so that double clicking on the icon will run a shell command. I
imagine this is possible on Linux too. If not, you could just set his
machine up so he pulls up a terminal and types "connect" or some such, and
it will do the rest.
