Remote destop app fails - connection closed

[ookooboontoo]

Hi all,

I have two Ubuntu Hardy machines though one has additional kde and xfce desktops installed but I have been working in GNOME.

I set up in System>preferences>remote desktop to view one of the pcs. When I go to the other computer through remote desktop viewer, I can find the computer to remote into but when I do, it returns

Connection to host adrian-laptop was closed.

I have tried playing with other port numbers, tried it the other way round and checked in case it was wireless playing up.

This is on a local network through a DG834 NETGEAR ADSL Router.

It seems my experiences are similar to this http://ubuntuforums.org/showthread.php?t=856413 but I have always got connection closed. I tried with the IP instead of the hostname but still no joy.

Has anyone any ideas?

Thanks

try using vnc

My situation may be different from yours, but for some reason when I get the "closed" message, I open up a terminal and ping the remote machine I'm trying to connect to.
After I do this, the remote desktop software immediately connects.

try using vnc

Thanks,

I tried that, with both java and tightvnc and still no joy.
in java I put in vncviewer adrian-desktop:3
and get
java.net.UnknownHostException: adrian-desktop

I put in vncviewer 192.168.0.3:3
and get
java.net.ConnectException: Connection refused

not quite sure which password tightvnc wanted me to put in but all trys failed.

Thanks, tried it but did not seem to work

did you ping it once or kept pinging?

I find the out put from remote desktop viewer is
Connection to host "adrian-desktop.local:5901" was closed.
Does that look right?

When I enter this into terminal:
ping ipaddresshere

I just let it sit there and ping my work machines IP until the viewer connects. Usually about 10-15 pings.
Don't know why it works for me though. Maybe it's "poking" my work computer awake. don't know.

Thanks for the idea I will try it tomorrow.

seems like a connection issue similar to firwall/nat block . When i used to get this kind of issues i used to try a smal http server like webfs(http://linux.bytesex.org/misc/webfs.html) and try to access the http://ipadress . If its working then the problem is specific to remote desktop.Also can try http://127.0.0.1 to check whether loopback is working. Best wishes

I tried this in several ways but sadly to no avail.

Thank you for this idea, I wonder if it is the router I am using. I think I will try first to hook it up to an independent hub to see if it will work itself out. This is going to bug me until fixed, I will need to see if I can RD a a Windows PC. I used to be able to on my old netgear router.

Thank you for your continued thoughts on this.
