Remote desktop connection Q?: How do I help across DHCP ISP?
Hello! I would like to be able to help someone on their MEPIS machine, preferably without going out there. I would imagine the Remote Desktop Connection is a good start, except it wants to use static IP addresses and neither of the ISPs that we use give those away for free (we're just home users without desire to purchase a static address).

In that other OS, you can start a remote desktop session through the MSN chat protocol. Is there any similar way to do that in Linux, with a GUI environment?

try this

looking at this:

ssh -R remote_port:localhost:22 your_home_computer
ex. ssh -R 2048:localhost:22
At home, you would then run ssh -p 2048 localhost to log into your work computer via ssh.
it seems to me that i still need a static location at at least one of the two, i.e.

am i missing something there?

Does your ISP assign you a private address (10.x.x.x / 172.16.x.x-172.31.x.x / 192.168.x.x)?

If your ISP does not assign any of the above addresses, you can use the dyndns ( or similar services ( . You can then connect to your friend's system using (I am not sure of their naming system) And in this case, you can safely ignore my previous posting as dyndns will keep track of the IP address changes.

thanks! I'll look into this (on both ends) and get back if I have questions... thanks again.

yeah i have a 10.XX.XXX.1 private IP...

any way to do a traceroute to from both ends and find a common link and then somehow tunnel through there? Probably not, huh...

I know that there is an "Invite Remote Desktop Session" in KDE but I think that we'd need to be on the same subnet or have a static IP for this to work...

no way to grab a chat session and go over that protocol?

If you are still looking for a solution ...

1. What is the IP that is assigned to your computer
2. Is this IP assigned by the router
3. What is the IP assigned to your router (by your ISP)

If the IP on the router's external interface is not private, you can enable NAT on your router.

this is my traceroute to

generic@1[~]$ traceroute

what is useful here? I'm not sure how to read it. Please note line 2 has two addresses that were slightly different (I also changed them to W, X, and Y for my safety)

I am not sure what the traceroute is from the other machine (the one that I'd prefer to administer remotely)
