I have a question which is probably elementary, but I am a
network ninny, and it puzzles me.
I have been ssh'ing into several other folks computers to assist
with stuff from time to time. One of them recently added a router
to his configuration and I am now unable to reach his machine. He
formerly had a cable modem going direct to his ethernet card, and
now that modem goes to his router, and from there two cables
emerge, one to his ethernet card and the other to the family
Windows machine.
Are there router configuration options that can restore my access
to his system? What should be changed to let me access him again?
The router is a Linksys something or other.
Thanks
Chuck

In the router configuration system there should be a place where you can forward ports on the external interface (the one hooked to the modem) to the internal interface to which the linux computer is attached. The port you want to forward is 22. Also most routers have an option which lets you use a computer on your network as a dmz. This means that all the ports that are not specifically forwarded elsewhere will go there. If you choose this your friend will want to be sure he has a firewall running on the linux box as it will be reachable by the internet.

Yup. At least on this linksys, go to setup, then advanced, then port forwarding. Then you'll see a form you have to fill out, first goes the service name, put ssh. Next come the range of ports, put 22 for both of those, in other words it will forward from port 22 to port 22. Check the boxes for the protocols, two of them, and the one to make it active. Also, it will have another edit box to enter the IP address of the user's local machine. They will have to assign it a fixed IP to make this work. Hope this helps. -- Currently playing: Dogon - Unit 33 Smokes A Beedee Good Vibes Radio: http://clearwhitelight.org/goodvibes Omeron - Effortless Union with the Divine "This quest may be attempted by the weak with as much hope as the strong.
