XRDP on Cent OS 7

Hi,

I have been working on how to set up XRDP on a centos 7 machine. For some reason XRDP is not in the EPEL repo. Maybe it is a 64bit arch thing since my machine is 64 bit?

I started with the directions posted on the XRDP site here:


This didn't work.
The X11rdp build step requires the package libxml2-python.

Next systemctl complain that the EnvironmentFile setting in xrdp-sesman.service points to a non-existent file. I tried copying ./instfiles/default/xrdp to /etc/sysconfig/xrdp.
Next xrdp-sesman and xrdp are installed in /usr/local/sbin, but the xrdp-sesman.service and xrdp.service points to /usr/bin.

So changed these things, reboot and nada. The systemctl status says xrdp starts fine after boot, but if I try to connect from a windows machine, xrdp gets shut down.

Aug 30 17:03:30 blackhole systemd[1]: Stopping xrdp daemon...

/var/log/xrdp-sesman.log shows

I hope the info above about installing on a centos box is helpful. I also hope you can suggest where to go next so I can get this up and running.

rate limit keyboard input

My security people are concerned about a particular attack vector and we haven't found anything on Google to help. I'm hoping someone here can -

The concern is if someone is remoting into a machine we have 'locked down' (stripped out a lot of packages/etc) and then they copy/paste or use a keyboard emulator to retype an entire application into the remote machine. For instance:

Local machine:
Take executable binary and convert to hexadecimal for easy copy/paste
Install software that emulates keyboard and will retype entire contents of the local machines clipboard (because we disabled copy/paste in xrdp)
connect to remove machine and create a file in remote home directory
Let software/keyboard emulator start retyping the entire executable


We think doing a keystroke logger on the remote end and pumping the logs somewhere could help monitor part of it. But we'd really like to rate-limit the incoming keystrokes because if the attacker aims too high (re: large exploit file size) then we can at least delay the inevitable and hope we notice in time. Particularly on the system in place where keystrokes would be very minimal (essentially a kiosk driven largely by mouse clicks).

Any thoughts or input would be appreciated.

xrdp-0.5.0-0.13.el6.x86_64.rpm

Hi,

I would like to request xrdp-0.5.0-0.13.el6.x86_64.rpm installer as my linux is not permitted to connect to the internet due to some constraints and I am not able to update my openssl libs as it is used by the application that is running on my RHEL 6 server. Apreciate if you could share the RPM for xrdp-0.5.0-0.13.el6.x86_64.rpm.

Regards,
Maizen

I got error during XRDP installation

Usually, the method of XRDP installation is as known as typing command "# apt-get install xrdp".
I tried so but I got the error, "E: Unable to locate package xrdp" despite I tried "# apt-get update"
Then I downloaded tar.gz (package) files from www.xrdp.org then I followed the instructions(README.txt & install.txt) but I got failed too.
Is there compatibility problem of device / OS version? Or.. is server operation discontinued?

(I used Raspberry Pi B+ & Raspbian)

H264 support

Hello,
I am trying to control remote desktop where most of the screen is
occupied by video playback (H264). This works well with Windows 10
remote desktop server, even over internet. Does not look well with
x11rdp though. I saw that over the years there were some discussions
about adding support for MS-RDPEVOR or implementing H264 codec in
librfxcodec. Is this still in the plans?

I looked at vrplayer and xrdpvr code (built it for Ubuntu 14.10 and
15.04)  but this does not work for me at all, (contrary to what I read
in previous discussion it does not look like RDPEVOR). Had it ever
worked?

log for rdp module from Xorg

Hello
Currently the default configuration for the rdp module from xorg in 
sesman.ini is set  to send logs to /dev/null

I find it more conveniant to remove this default config: For a non root 
user, Xorg logs are sent to XDG_DATA_HOME/xorg/Xorg.n.log which points 
to $HOME/.local/share/xorg/Xorg.n.log for most distributions

This permit to keep trace for debugging, and it's stored on each 
user'HOME which fix permissions issues

Question about session

Hello xrdp developer,

I got a problem about sessions which could not be deleted when the session timeout or other situations. How can I close the zombie sessions? Could you apply it?

Thanks for your reading,

xrdp version problem

Hello, All:

I'm seeing the newest version of xrdp is 0.6.1 in www.xrdp.org. But on GitHub the newest version is 0.8.0, and I'm wondering if there is some difference on these version and which version should I choose? And is the version 0.9.0 is under development?

Thanks.

XRDP access log

Hi,

I successfully install XRDP(0.6.1) and VNCServer on a XRDPserver.

When I remote logon to the XRDPserver from my NB(Windows 7),

Can you kindly help to inform me where the access log is?

I assume the access log should include my NB IP, user name, logon timestamp…ect.

Thanks.

 

Best regards,

Edward

vncpasswd

Hello,

In every xrdp/vncserver tutorial it is indicated to use the command `vncpasswd` after creating a new user but I see that it is enough if I set the user into the tsusers group and set an entry for it in the `/etc/sysconfig/vncserver` file. When I login through the RDP client with the user's password it lets me in, seems to be working without any problems.

I'm building a system of scripts which creates users with RDP access, I would love to skip dealing one more time with the user's password if it is stable this way as well. I hope it's not a bug but the default behavior of vncserver and not a bug that will be "fixed" in a future release. What are your thoughts on skipping the `vncpasswd`command?


Running on a Centos 6.4 I use the following packages:

    tigervnc-server-1.1.0-8.el6_5.i686
    tigervnc-server-module-1.1.0-8.el6_5.i686
    xrdp-0.5.0-0.13.el6.i686


Thanks.
