Router and SSH, etc.

[theroguechemist]

Hello again. I'm talking mostly about/around SSH'ing here. I have a iMac that's linked with some other computers in my house to a router, connected to a dsl line. My question is this: How can I SSH in to my computer from another computer, across the plain old internet? Is that even possible? Or do I need to buy something more for it to work? I've been searching endlessly, I think it has something to do with SSH tunneling, but I don't know what that is or how it works.

My best thought on this is that:

Some other computer > my dsl line IP > router IP> Mac computer IP(assigned by router).

I'm hopelessly lost. Any help would be great.

Since you said "any help would be great":
how will you manage your temporary ip from your dsl-line? Or are there some dns2go-services for macs too?
Ok, I know it is possible what you are trying to do. The only thing that is confusing me is how you can specify your lan-machine. Maybe through ports?
Sorry for being no help, but I am sure some other ppl will help you out. I was just interested how you manage the temporary ip problem...

Textbook example of what you want to do.

As long as your router supports port-forwarding, all you need to do is open a port on TCP/22 (or whatever you choose to use on your SSH server) from the external interface to the internal IP address of your machine.

As far as a dynamic DNS name being mapped to your public IP address, any of the services work although not all have OS X clients; you can always use one of your other computers as well to poll your external IP and update the dynamic DNS record. Some routers provide this functionality as well.

Cheers.
