rdesktop/xrdp: error - problem connecting (to 127.0.0.1 5910)

[mikko.ostlund]

Hi!

Abstract: I have installed xrdp in Fedora Core 5, but fail to connect to
it with "rdesktop localhost". I'm hoping someone can help me to get it
working.

Details about my system:
* "uname -a": Linux desktop 2.6.17-1.2174_FC5 #1 Tue Aug 8 15:30:55 \
EDT 2006 i686 i686 i386 GNU/Linux
* Gnome version: 2.4.13
Distributor: Red Hat, Inc
Build date: 08/02/2006
* rdesktop version: 1.4.1
* xrdp version: 0.3.1
* Firewall: "Disabled" (in dialog "System"->"Administration"->
->"Security Level and Firewall")
* SELinux: "Disabled" (in the same dialog as the firewall above)

Details about how I installed xrdp:
1. I browsed to
http://sourceforge.net/project/showfiles.php?group_id=112022&package_id=195021&release_id=435591"
and downloaded "xrdp-0.3.1.tar.gz".
2. I unpzipped it with "gunzip xrdp-0.3.1.tar.gz".
3. I untared it with "tar xvf xrdp-0.3.1.tar".
4. I entered the xrdp-0.3.1 directory with "cd xrdp-0.3.1".
5. I built the whole project by running "make" in the xrdp-0.3.1 directory.
6. I switched to the root user with "su".
7. I installed everything with "make install".

Details about how I ran it and how the problem occurred:
1. I started xrdp by running, still logged in as root, "/usr/local/xrdp/xrdpstart.sh".
2. In another terminal window, logged in as a normal user, I ran "rdesktop localhost".
3. A window, titled "rdesktop - localhost", appeared.
4. Inside the "rdesktop - localhost" window a subwindow appeared. The title of the subwindow was "Connection Log".
5. In the subwindow, the following text appeared:
"started connecting
connecting to sesman
sending login info to sesman
receiving sesman header
receiving sesman data
sesman started a session
connecting to 127.0.0.1 5910
error - problem connecting"
6. End of story; nothing further happened.

Contents of file "/usr/local/xrdp/sesman.log":
[20060824-16:27:30] [DEBUG] starting sesman with pid 3727
[20060824-16:27:30] [DEBUG] listening...

[20060824-16:27:41] [DEBUG] session 3730 - user mikko - terminated

The following files contained nothing (size 0 bytes):
"/usr/local/xrdp/sesman.boot.log"
"/usr/local/xrdp/xrdp.boot.log"

The user "hela" of this forum, seems to have got around the problem by
installing "kubuntu-desktop" (refer to the posting
http://www.ubuntuforums.org/showthread.php?t=239616), but I would like to
see the problem actually solved for the Gnome desktop.

Appreciating any attempts to shed some light on this,

Found this little tidbit, don't know if you tried this or not yet:

/usr/local/xrdp/startwm.sh

should look like this

#!/bin/sh

gnome-session

Make sure you make a backup of startwm.sh before anything.

[mikko.ostlund]

Yeah, I already tried that; no visible difference. Thanks anyway, Sbassett!

I made the following experiment to get more information.
I made the file "/usr/local/xrdp/startwm.sh" look like this
(the dashed lines just symbolize the beginning and the end
of the file):

-----------------------------------------------------
#!/bin/sh
gnome-session >/home/mikko/gnome_session_log.txt 2>&1
-----------------------------------------------------

(I.e. I redirected the standard output and standard error of
gnome-session to the file "gnome_session_log.txt" in my home directory.)

Having run "/usr/local/xrdp/xrdpstart.sh", followed by "rdesktop localhost",
again, the contents of the file "/home/mikko/gnome_session_log.txt" was
as follows:

[mikko@desktop ~]$ cat gnome_session_log.txt
SESSION_MANAGER=local/desktop:/tmp/.ICE-unix/4355
The program 'gnome_segv2' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
(Details: serial 470 error_code 8 request_code 72 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
Window manager warning: Log level 32: could not find XKB extension.
Window manager warning: Lost connection to the display ':10.0';
most likely the X server was shut down or you killed/destroyed
the window manager.
[mikko@desktop ~]$


It is obvious that something is wrong, but what? Can anyone help
me here?

I appologize for having added this thread to Ubuntuforums;
it's a Fedora Core 5 issue. It was by mistake; I have an
Ubuntu laptop from which I want to rdesktop to a Fedora
Core 5 desktop. However, the Ubuntu is not yet involved
here. This thread is (at least so far) only about the
problem I saw then running "rdesktop localhost" on the
Fedora.
