ssh to multiple lan machines from the internet - How?
 

I have a question regarding using ssh to access a machine on a personal network from a remote location?

Is it required to use different incoming ports for each machine on the lan eg

10.0.0.1:400
10.0.0.2:401

and if so, what files would i need to change.

If their is a simpler method/approach, could you point me to the answer.

Thx

Ports sounds like the way to do it.

I assume you are using a singe machine with a single ip address as a gateway. You will need to add either iptables or ipchains rules to that machine that point to the internal one(s) you want to access.

I am using a router for dhcp etc, plugged into it are 3 switches and a whole load of machines. SSH from the lan side is easy, but i want to be able to go on holiday and still do remote admin, from net cafes abroad :)

Thx anyways

do you have a linux firewall before the router? if you have a linux firewall then you can use the iptables or ipchains rules (as david pointed out ) to forward all the traffic to a specified port to a internal machine. you can then run the ssh server on the internal machine on the specified port. if you dont have a linux firewall then you need to confiure port forwarding on the router.
you need to setup the individual ssh servers on the internal machines to listen on different ports.

Either that or just forward to one box and then ssh from there to the others - the choice is yours.
