Do you have SELinux running on the machine by any chance? If so, did you install xrdp-selinux package?

Also, new TigerVNC packages require some extra options, which are mentioned in README.Fedora file. Did you apply those to your config?

Comment 4

Dean Hunter

2017-06-26 22:12:22 UTC

Thank you for your response.  Yes, I have SELinux running.  No, originally I had not installed xrdp-selinux, but since filing this bug report I found the README.Fedora.  I did:

1. sudo dnf -y install xrdp-selinux
2. sudo reboot
3. logged into Gnome
4. xfreerdp /v:localhost

but the problem persists.  Then I editted the VNC stanza of sesman.ini and restarted xrdp, and again the problem persists.

Comment 5

2017-06-26 22:24:24 UTC

By the way, README.Fedora references /etc/X11/Xwrapper.config which dies not exist in my installation.

If you're running xorgxrdp, you will need to create that file. Does not apply to VNC.

Anything in the audit logs about SELinux denials?

Also, what you you have in /etc/pam.d/xrdp-sesman? Default or Gnome specific stuff (i.e. gdm-password entries)?

Comment 8

Dean Hunter

2017-06-27 21:39:23 UTC

Thank you for the note about Xwrapper.config.  I have had not notices about SELinux denials.  Please remind me how to search the audit log for denials.

>cat /etc/pam.d/xrdp-sesman
#%PAM-1.0
# Generic Fedora config
auth       include      password-auth
account    include      password-auth
password   include      password-auth

#account    include      gdm-password

#session    include      gdm-password

Comment 9

Bojan Smojver

2017-06-27 21:42:37 UTC

To search for denials, try:

grep denied /var/log/audit/audit.log

You may also want to convert that into a more readable SELinux format:

grep denied /var/log/audit/audit.log | audit2allow -m denials

Try using Gnome specific stuff in xrdp-sesman PAM configuration. That is what I have on my VM that runs xrdp and Gnome.

Modified /etc/pam.d/xrdp-sesman to be:

#%PAM-1.0
# Generic Fedora config
#auth       include      password-auth
#account    include      password-auth
#password   include      password-auth

# Gnome specific Fedora config
auth       include      gdm-password
account    include      gdm-password
password   include      gdm-password
session    include      gdm-password

then restarted xrdp but the problem persists.

I'm out of ideas, so try to strace the xrdp processes when you login to see what's happening. There were problems with IPv6 at one point as well, so you may want to try disabling that.

Comment 13

Dean Hunter

2017-06-29 00:42:17 UTC

I am not familiar with strace.  Can you give me the command lines for which you would like to see the output?

Comment 14

Bojan Smojver

2017-06-29 00:45:46 UTC

Posting all of strace output will probably not be practical - the program prints out system calls. So, you would need to be able to determine which system call is resulting in the problem that may be related.

Normally, you want to see which xrdp processes are running when the service is started and then run:

strace -f -p <pid> -p <pid>...

This will then follow the forks of these processes as well.

Looked at the strace output and I can only see what appear to be timeouts to be back end (i.e. the VNC process), if I'm reading that correctly. I'm not any smarter after it, I'm afraid. :-(

Comment 19

Bojan Smojver

2017-07-20 00:35:23 UTC

Do you have this set in /etc/xrdp/sesman.ini when you're running the VNC session:

param=-AcceptCutText=0
param=-SendCutText=0
param=-SendPrimary=0
param=-SetPrimary=0

Comment 20

Dean Hunter

2017-07-24 17:13:06 UTC

So xrdp is timing out while trying to connect to VNC?  I have only the default configuration of VNC provided by a new install of Fedora 26.

Installed Packages
tigervnc-license.noarch                     1.8.0-1.fc26               @anaconda
tigervnc-server-minimal.x86_64              1.8.0-1.fc26               @anaconda

None of the parameters you listed are set in the sesman.ini built by a new install of Fedora 26 and I have not changed the file.  In which stanza do they belong?

Comment 21

Dean Hunter

2017-07-24 17:40:09 UTC

I found that I had tried this test before with a ticket opened with Neutrino Labs: https://github.com/neutrinolabs/xrdp/issues/765  So I added the params to the [Xvnc] stanza, restarted xrdp, and tried again with the same erroneous results.

I see some new information in the ticket from grishin-a that says there is a problem with xrdp-selinux.  Can you review it and advise whether it really applies to this problem?

Comment 22

Dean Hunter

2017-07-24 18:14:02 UTC

grishin-a is using the MATE desktop where I am using the standard Gnome desktop.  grishin-a is installing oddjob-mkhomedir which is not installed with Fedora 26 Workstation.  His changes to xrdp-selinux seem to be limited to to including oddjob-mkhomedir.

Per README.Fedora:
---------------
TigerVNC 1.8.0 enables clipboard support by default (i.e. no need to run
vncconfig), which may cause disconnections in xrdp. To avoid the issue, these
can be added to [Xvnc] stanza in /etc/xrdp/sesman.ini:

param=-AcceptCutText=0
param=-SendCutText=0
param=-SendPrimary=0
param=-SetPrimary=0

Of course, cut and paste support will not work with these set.
---------------

This was sprung upon us in xrdp world without any notice and there must be some kind of bug in xrdp that is causing disconnections. Given that recent Fedoras can have both version 1.7.x and 1.8.x of TigerVNC installed, I didn't want to set this as default.

Also, without patched xrdp, passing that =0 would not work anyway.

I know, less than ideal...

The SELinux theories are always easy to prove/disprove - just turn it off or put it in permissive mode. If it starts working, it was SELinux.

Comment 26

Dean Hunter

2017-07-26 17:36:41 UTC

I created a new VM with gnome-boxes and Fedora-Workstation-Live-86_64-26-1.5.iso.  I applied all updates then installed, configured using all of your advice, and tested.  Xrdp still does not work.  I have attached the log of my work, see Comment 25.

I know you said Xrdp works in your VM, what am I doing that is different?

Comment 27

Bojan Smojver

2017-07-27 03:00:45 UTC

I am thinking that maybe some component is missing to run gnome properly. Can you run gnome all by itself on that VM?

Comment 28

Dean Hunter

2017-07-27 23:09:00 UTC

Yes, Gnome seems to work.  I have used Activities to run Terminal to install and test Xrdp, Files to find the configuration and log files, Text Editor to edit the configuration files, and Software to update the installation of Fedora 26.

Did you use Fedora 26 Workstation for your VM?

My VM is an upgrade from (I think) F25. I think I may have used the workstation product to install it.

Comment 30

Dean Hunter

2017-08-02 16:51:47 UTC

I created a new VM using Fedora-Workstation-Live-x86_64-25-1.3.iso, then followed the same procedure as in Comment 25 to install, configure, and test Xrdp.  This installs the same version of Xrdp as with Fedora 26, and, without surprise, produces the exact same erroneous results.

I was trying to reproduce your VM where you say Xrdp works.  So I will not be able to compare a working installation with the installation created from Fedora 26 Workstation Live.  Please, can you tell me what is missing?

> Please, can you tell me what is missing?

I honestly wish I could. There is bound to be something that I must have done by hand to get mine working (although I don't remember it), but I cannot remember what any more, if anything.

I do have root logins turned off in my sesman.ini. That surely cannot be it.

Comment 32

Dean Hunter

2017-08-03 00:01:16 UTC

I REALLY do not understand.  Could you not create a Fedora 26 Workstation VM, as I have done, and compare it to the VM where you say Xrdp is working?

I will do that when I get an opportunity.

Comment 34

2017-08-03 01:12:02 UTC

Here is another data point: I built another VM using CentOS 7.0, updated, installed, and tested Xrdp.  It works with the default configuration.  The first difference I see is that CentOS 7 is using a different version of TigerVNC:

Try:

Then reboot. Then try an RDP connection. See if that works.

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

24 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

Hmm, interesting. I set up an F26 VM and installed xrdp on it. Originally it was set to boot in graphical.traget and the logs were showing Gnome Shell errors when I tried to connect to it (probably some kind of clash with gdm's shell). Once I switched to multi-user.target (i.e. non-graphical), I could connect to it using remote desktop client in Windows over RDP.

Just to avoid confusion, I blew away the F26 VM I created earlier and set it up again. I did that on Windows 10 with VMware Player 12 something (the free download from their site). I use x86_64 live image of F26 workstation to set up the VM, all defaults. I added user test (with password).

Once I booted into the installed VM, I switched to VT2 and did the following (paraphrasing here):

- systemctl set-default multi-user.target
- dnf install xrdp-selinux (this installs xrdp as well)
- dnf -y update
- cut/pasted TigerVNC stuff from README.Fedora into Xvnc stanza of sesman.ini
- edited /etc/pam.d/xrdp-sesman and enabled gdm stuff instead of standard
- firewall-cmd --add-service=ms-wbt --permanent (or something to that effect)

Then I rebooted and used remote desktop client from Windows 10 to connect to the address of the VM. You will see the result in the image I'll attach. Basically, Gnome ran just fine.

Thank you for your patience.  I have verified that it is necessary to shut down the graphical interface for the console on the machine running Xrdp.  This is something new to me on Fedora, although it has been a few years since I have tried this.  And it is not necessary on CentOS 7 running the same version of Xrdp.  Can you spare a few more minutes to explain why it is necessary?

I feel I must apologize for being an idiot.  Shutting off the graphical interface to the console worked because it forced me to use another VM workstation to test the connection instead of trying to connect to localhost, as I have been able to do with CentOS.

I followed instruction on comment #39, so that the Vnc username and password can pass.

But then the RDP session will got cut immediately afterwards.  

I can see the Gnome desktop wallpaper show up for a while before connect is cut.
