Internal Error have not been able to connect #54

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Install neatx on an LFS install
2. Install a client on a Ubuntu machine
3. Try to connect

What is the expected output? What do you see instead?

The expected output is a working nx session
Instead I get NX> 500 Internal Error

What version of the product are you using? On what operating system?

The server is running on our company's embedded linux system, which is 
built from scratch. And the client is running on Ubuntu 9.10

Everything is up to date with the SVN

Please provide any additional information below.

Here is what I am able to get from the /var/log/user.log

(p.s. logging in as root is not the issue, this happens for any user)

I'm doing a similiar thing, but client side is ubuntu 9.10 64bit desktop, and 
server is 10.04 x86 desktop with neatx.

I see the same problem.  Ubuntu 10.04 x86_64 server with both Ubuntu 10.04 
nxclient and Windows client.  (Implies problem may be with server?)  This log 
is from windows client, but linux output looks similar.

Is there any way of killing the session, so that I can regain graphical access 
to the server?  A reboot doesn't do it.

Thanks,

Chris.

to restart session i'm doing this:
cd /var/lib/neatx/sessions && rm -rf *

then reboot to kill all X app's and after that connecting again.

on Debian/testing, getting the same generic nondescript "500 Internal error" 
when I try to reconnect to a session I've been disconnected from. tried using 
various wm's; openbox, awesome, i don't see a gnome 2.x to try and add in 
debian.

i'm afraid no one on this chain really knows what to do to generate more useful 
debugging information for this ticket. :( the 500 Internal error is so generic.
