 Posted: Wed Aug 17, 2005 12:59 am Post subject: Domain for accessing internal network |
 |
|
| I have purchased a domain, lets call it "mydomain.com", and I'd like to use it to access the computers on my internal network remotely with ssh. I have a dynamic ip address and have configured a computer as a router (and webserver) to provide access to my other machines. I've had some success with No-IP in accessing the router machine, lets call it "router.mydomain.com". However, I haven't yet figured out how to configure my network so as to access the other machines behind the router, lets call them "machine1.mydomain.com, machine2.mydomain.com, etc". I've looked into a bit, and think I might have to run some dns software, but I figured I'd see what people recommend before I get too into it. So does anyone have any suggestion, or had success with a similar setup? |

You could always access the other machines behind your router by IP address, although if you have a lot of them with DHCP configurations that would be less than desirable. I only have 3-10 machines up behind my router at a time so I assign them static IP addresses and access them by IP address after I connect to the one machine that is accessible from the Internet.

| Yes, I am aware of that. But I was hoping for a more elegant solution, its a bit of a nuisance to log into a machine just to log into another one. |

| You could map different external port numbers to specific machine's IP and port 22. Then you ssh to [external IP] port 2201 (say) and get machine 1, 2202 etc. We do this kind of think at work. |

Thats actually how I have it configured now.
So is there no way to access machineX.mydomain.com, behind the router, directly without specifying port numbers or logging into the router first? |

You would need a seperate Internet facing IP address for each machine in question for that to work, AFAIK.

You need to specify the port numbers. You don't log into the router. |

That's right, it is generally a poor security practice to allow access to your router from the Internet. That would make your router a target for many attacks -- which is a very bad thing. You should only allow access to your router from your local network.
