Re: Introducing BlueMaemo

is anyone having problems running ssh in the new ubuntu 8.10? Before, everything worked fine, but now it says that the display can not be found and stuff. I am not trying to x-forward, just use normal ssh to control the computer! I WANT it to run on the server, not the nokia, but nothing works.

$ ssh -l name@ip firefox
cannot find display (or something like that)

I have dsa keys already setup, and they work...

Nothing works, but I have not tried cmd line apps yet... It would be great if i could get the auto connect to work...

Re: Introducing BlueMaemo

There was problem with somes keys,
look at your host messages (/var/log/auth i guess)
if you get a message like
48:de:55:22:xx:yy:zz:yy:xx:yy:zz:yy::88:e8:87:47 blacklisted (see ssh-vulnkey(1))
that's you need to re-create your key on client and re-send on host.

You realize that if you don't use X-Forwarding, you can only do command line apps, right? Graphical apps require X-Forwarding or VNC.

Unless... you're trying to start an application from the ssh command line, and have it run on your primary computer's display?

Re: Introducing BlueMaemo

maybe he just want to launch firefox on remote computer Xorg ...

Exactly. I have no idea why this is not working. I'll try some stuff like the DISPLAY and see what happens.

But, does anyone use the new ubuntu and have these problems? Is it to do with the new Xorg configuration (or lack thereof)?

Code:

ssh thesandlord@172.16.10.13

Linux thesandlord-desktop 2.6.27-7-generic #1 SMP Thu Oct 30 04:18:38 UTC 2008 i686

thesandlord@thesandlord-desktop:~$ firefox

Error: no display specified

thesandlord@thesandlord-desktop:~$ rhythmbox

Cannot open display:

Run 'rhythmbox --help' to see a full list of available command line options.

thesandlord@thesandlord-desktop:~$

It also looks like 8.10 hates static IP, so now my internet is broken. Back to 8.04 for me...

Edit: I don't want to hijack this thread, and I don't think its a tablet problem, so...

Re: Introducing BlueMaemo

No, it has nothing to do with Ubuntu.

I told you:

DISPLAY=:0.0 firefox

Now, listen.

I guess I'll check if logging is enabled in sshd_config. Don't know why I'm doing all this hehe.. I still gotta plug in the bluetooth dongle into my laptop when I wanna use it.

Re: Introducing BlueMaemo

The DISPLAY worked, even though it is horribly slow... Due to a number of problems, im switching back to 8.04 or Mint, in which Bluemaemo work perfectly, ssh did not need all this complicated stuff, networking actually allowed static IP...

Re: Introducing BlueMaemo

8.10 just came out. Give it some time. Any new software release has rough edges. 8.10 (+ GNOME) also has some issues with BlueTooth. People report issues with suspend to RAM (I can confirm).

If you SSH into a computer it should not have a DISPLAY variable set. You have to do this manually. It should not be horribly slow, and this shouldn't have anything to do with SSH because the command is running remotely. Does it work fast when you run the application local? If you put ssh -fXT user@ip DISPLAY=:0.0 $1 in script.sh, chmod +x, and then ./script.sh firefox you have no TTY is assigned and the command is forked into the background. It then runs remotely, and shows on remote screen.

If you'd add the -X flag to the ssh command you'd run it local without assigning TTY, forking in background. You can also add -C for compression (but overhead on lil NIT might or might not be worth it; I don't know).

You can also run QtNX a client for running remote X applications with low latency, heavy compression, and resuming on the server. Its like a 'screen for X' with the speed of RDP.

Latter 2 are for showing the application on the NIT running the app remotely.

PS: If you run nothing on the remote computer except a plain X server with no apps running, and you fire up Firefox, a lot of libraries have to be loaded. This takes some time. If you'd already run GNOME (with GTK2, and a lot of other libraries) many of these libraries are already loaded. [This is only true for shared libraries; but that is the case here.]
