remote access ssh behind wireless

Asked by John Zorro

Win XP Laptop, Ubuntu 10.04 Desktop need local and remote access to Ubuntu via FreeNX running SSH. Both hooked to a wireless router Linksys WT54G. I've read of so many different ways to do this but this looks the best in security and cost. So many questions and to much information. I don't believe I need a static IP with Dyn, I don't think I need NAT tables. I've read some directions where you need to give a "sample". What is a sample when you are giving directions? Are chains the same as stings? I think this is a common set up and it would be great if somebody could redo a step by step template. I believe I've set up SSH but don't know. I have the client side installed from nomachine on the laptop. Thanks

Are both PCs on the same LAN?

Hi John,

Can you simply tell me what do you want to do exactly? You want to acess ssh of ubuntu from windows XP?

Yes I would like to access ubuntu from windows xp locally and remotely with the security of SSH. They access the internet on the same Linksys WRT54G. When I am remote and local I have dual monitors. I would like to view each OS on it's own monitor sharing laptop keyboard and mouse for both. Ubuntu is CAT5 to the Linksys and WinXP is wireless to the Linksys but cannot see each other. Thanks

You can use VNC. and the remote OS will be viewable in a window which you can drag to the other monitor. The wired connection section will make things a lot faster as it is directed media rather than slow broadcast which the wireless is.

Ubuntu comes with an inbuilt VNC server and you can use any VNC viewer for windows you can get your hands on.

Why do you want the other systems screen? There are often more graceful methods to achieve your goals as many apps have web interfaces built in. Torrent clients are a classic here.

I looked at VNC but from what I read I need SSH for security disallow passwords and use keys. If I can use VNC with SSH could you tell me how?

ouu are only accessing the system over LAN so security isn't an issue. You only need to use VNC over SSH if you are accssing it over WAN ro secure the data as VNC uses no encryption. Here is a guide on how to use VNC through an SSH tunnel if you are convinced you need one (but you don't):

Win XP is a laptop and I will need remote access. Isn't FreenNX a "lighter" solution? I'll keep playing with it thank you all for the help just the same.
