Connection issue

Sling Box — 2013-05-16T13:12:01

Hi,

I just installed the latest version of xrdp on a SUSE Linux Enterprise
Server 11 SP2 install, but I get the following when trying to connect from
a client system:

connecting to sesman ip 127.0.0.1 port 3350
sesman connect ok
sending login info to sesman
login successful for display 10
started connecting
rdpx11 channel is not present
X11 RDP server started
Screen depth is not 24

I hit OK (the only option), and the connection terminates.

Can anyone point me in the right direction? I followed the install
instructions here:

Hi,

----- Original Message -----

X11rdp is the one backend that allows for session disconnection / reconnection with arbitrary resolutions and colour depth.

IMHO, go for X11rdp.

Xvnc or X11rdp

Abraham Macías Paredes — 2013-05-15T14:38:30

Hi everybody,
I've read that XRDP Works with Xvnc or X11rdp.
Which one offers a better performance?

I've looked at the source code and I can't understand how it works.
In what C source code file is made the communication between the Xvnc server of the user session and the XRDP server?
Where and how it's done the transformation from the application X windows system calls into RDP packages?
Is there any detailed documentation?

Thank you very much!

Abraham Macías Paredes

Hello,


Did you have tried DMX instead of X11rdp ?

Suse use 0.4 xrdp version, i think it will be not easy to integrate in

Suse have develop this for their feature "NOMAD".

Yes (if you want to use X11rdp)


Because I took the original Debian packacking, replaced xrdp with the version from GIT and than enabled X11rdp.
Since Debian never built X11rdp, they never experienced the permission problem and took the right approach to not run an network facing daemon with root permissions.
In our UCS package we took the easy root and run xrdp as root, but I'd advise you not make that network port publically available.


That's part of our univention-xrdp package, which also contains the integration into our management system.

Re: How to disable clipboard on xrdpv0.6.0

Oops, sorry Philipp, I'll get this in now.

Lee, I don't think the [channels] section will work with 0.6.  I think
that was added later.
0.6.0 does not have drive redirection so there is nothing to disable
and the clipboard was pretty limited.

RDP_NORMAL_LOGON in xrdp_constants.h

Stephen Yorke (DN — 2013-05-11T01:31:09

Jay,
After talking to some MS RDP experts/developers, we have found an error in your code.

Your RDP constants header file show:
   RDP_NORMAL_LOGON = 0x0033

It should actually be set to 0x0013.

0x0033 sets the Maximize bit (0x0020) and 3rd party RDP developers would have issues with this if they are expecting/requiring 0x0013 as a normal response.

I currently patch my 0.7.0 xrdp with this and all works fine for all 3rd party RDP stuff that I use.  I only had a person look at it because I could not get logged on properly using a certain piece of software but figure I would bring it up to you first here because there may be a specific reason why you are using 0x0033 for a Normal Logon request.

Thanks in advance,
-Stephen

Re: /etc/init.d/xrdp in version 0.6.0?

Stephen Yorke (DN — 2013-05-08T19:57:32

I have used xrdp 0.6.0 from source in the past few days and can assure you that the xrdp.sh script works.

One thing you will need to make sure of though is X11rdp...if that is not there then it will not work.

Personally, I think you should move to xrdp 0.7.0 and not touch 0.6.0...

Absolutely, it is standard practice in just about every installer that I

none of the above are detected it is normal practice.

pulse sink

Jay Sorg — 2013-05-07T23:40:59

Hello,

I create some pulse sink notes at
http://www.xrdp.org/index.php?option=com_content&view=article&id=19:xrdp-pulse-sink&catid=2:documents&Itemid=7

configure xrdp without --enable-simplesound for this.  I think I'll
remove the pulse simple API option if the sink method works.

With the simple API, it was a pulse monitor that had to pull the pulse
audio server.  That mean that even if no audio is playing, the loop is
running.  With the sink model, all threads are resting nicely when
nothing is playing.

In the future I could see this sink going into the pulse upstream and
even add a way to detect if it's an xrdp session and default to the
appropriate sink.

I changed startem.sh to autodetect but when a session is started but
we can't do that with the pam file.

Is it OK for 'make install' to look for these files and install the correct one?

/etc/init.d/xrdp in version 0.6.0?

Re: startwm.sh

Jonathan Buzzard — 2013-05-02T22:37:02

The usual thing is to look in /etc for redhat-release, debian_version or
SuSE-release. Then depending on what you find install stuff where 
required with some default if none of the above. It also gives you the 
option of doing something different if say RHEL5 is different from RHEL6 
by looking at the contents of the file.

Re: startwm.sh

Hi,


That is cool!


I would just suggest that you keep the pam.d file variations in the repository. The community can contribute with changes when/if needed for those files. And then we all can package directly from the repository.

startwm.sh

Jay Sorg — 2013-05-02T19:03:28

I've noticed the localtion of Xsession on Suse 12.1 is
/etc/X11/xdm

Debian / Ubuntu is
/etc/X11

EL is
/etc/X11/xinit

Is this right?
I can change the script to auto detect it's location.

I don't know what we can do with the pam.d file.

As part of installation, maybe a manual step.

Re: /etc/pam.d/xrdp-sesman

Gustavo Homem — 2013-05-01T19:56:00

Stephen,

I think the problem is that EL, Suse and Mandriva use system-auth whereas Debian (and Co.) call it common-auth. Same goes for account, session and password.

So, it is the same thing with different names.

Ways to solve this within the xrdp repo

1- have a default file that works for Debian, Ubuntu, etc and an extra file (xrdp-sesman.EL) that works for EL, Suse, etc
2- have a default file that works for EL, Suse, etc and an extra file (xrdp-sesman.Ubuntu) that works for Debian, Ubuntu, etc

Either the Debian people or the EL people will have to copy a file in their building scripts. But that's trivial to whoever is able to package anything :-)

I really think the repository should keep *both* files, so that packagers don't have to carry along a separate files all the time.

We can work together to have 1) ou 2) so that the central repository works for everyone.

Suggestion: ask Jay to integrate the pam file that works for EL in the way he prefers and adapt your script accordingly, to build directly

Re: /etc/pam.d/xrdp-sesman

Stephen Yorke (DN — 2013-05-01T00:42:09

Jay,

Xsession on EL is located in /etc/X11/xinit.
On Debian based systems, it is usually in /etc/X11.


As for the /etc/pam.d/xrdp-sesman, I think we should discuss the best way to do it.  I know for my EL builds, I find it easiest to use the system-auth links that I posted in a previous e-Mail.  Others said that will not work on all distributions though.  Which I do not really understand because it is pam.  Shouldn’t it work the same way on all systems?  I am actually going to look into this a little more because I want to write a single script which will build my systems whether they are EL or Debian based distributions.  My current script works perfectly for EL (CentOS and Red Hat) and after running it, everything ‘just works’.

I'm planning to put the file
/etc/pam.d/xrdp-sesman
back like it was.
Also, I seen a system that does not have

so I think I'll check for the existence and if it's not there, do the old way.
