Navigation does not work in thinclient_drives with the last PKG

[JM-Teule]

Hello,

With the latest "Sudo Apt -Get Update - Upgrade" in my Buster Raspberry Pi distribution, XRDP has been updated.

The following packages will be updated: "... Vim-Tiny Wireless-Regdb XRDP Xserver-Common Xserver-Xorg-Core XXD"

Since then, navigation does not work in thinclient_drives. The shared file folder appears empty continuously.

The previous version that works (OK):

"PKG_CONFIG_PATH =/BUILD/XRDP-Q47NHL/XRDP-0.9.9/PKGCONFIG"

The current version that does not work (KO):

"PKG_CONFIG_PATH =/BUILD/XRDP-X6KNLD/XRDP-0.9.9/PKGCONFIG"

What does dpkg -l xrdp give you for both? Has xrdp been patched by the distro?

[JM-Teule]

1- dpkg -l xrdp xRDP OK ii xrdp 0.9.9-1+deb10u1 armhf Remote Desktop Protocol (RDP) server

xRDP KO ii xrdp 0.9.9-1+deb10u3 armhf Remote Desktop Protocol (RDP) server

2- Has xrdp been patched by the distro?

with sudo apt-get update + sudo apt-get upgrade

The differences between xrdp 0.9.9-1+deb10u1 and xrdp 0.9.9-1+deb10u3 don't seem to be related to this area:-

xrdp (0.9.1-9+deb9u3) stretch; urgency=high

  * Fix patch for CVE-2017-16927. (Closes: #884702)
    + Off-by-one mistake could crash xrdp in some cases.

xrdp (0.9.1-9+deb9u2) stretch; urgency=medium

  * Fix CVE-2017-16927. (Closes: #882463)
  * Fix high CPU load on ssl_tls_accept. (Closes: #884453)

Get a command prompt up. What do you get for ls ~/thinclient_drives?

[JM-Teule]

ls ~/thinclient_drives
My_LC

`ls /home/pi/thinclient_drives/My_LC

2019-10-11-125251_1920x1080_scrot.png '3d Tag Cloud.livecode' 'Achat Web.livecode' advanced-multimedia.livecode aGarderEtiquettesQR.livecode alignement.livecode .... ` and all the share is on the shell but not in pcmanfm of raspbian buster...

One more thing, I uninstalled XRDP and I reinstalled it: no difference.

[matt335672]

Sorry, I don't understand what you are saying. What is My_LC? Is it a share?

[JM-Teule]

Yes from Microsoft Remote Desktop

[matt335672]

I still don't understand. It sounds to me like xrdp is working properly. Is it just the file manager on the desktop that isn't allowing the browsing?

[JM-Teule]

yes, xrdp working fine, not the mount of thinclient_drives, after the last update of xrdp or something else.

That's just what I indicated from the first post

[matt335672]

@JM-Teule

I don't think we're understanding each other.

When I say "xrdp is working properly", I'm including the remote mount in that. You can browse files which are being exported by your xrdp client in your xrdp session from the command line using standard command like cd and ls. Is that right?

Can you access the files from the command line? What do you get for these commands:-

ls -l ~/thinclient_drives/My_LC/2019-10-11-125251_1920x1080_scrot.png
cksum ~/thinclient_drives/My_LC/2019-10-11-125251_1920x1080_scrot.png

Hello,

Sorry for that.

2 short videos will be better than long texts :

I'm afraid I'll have to insist on the textual description.

Other people may be reading this and searching for a solution to their problem. Also, viewing unsolicited videos simply isn't safe on the modern internet.

[JM-Teule]

I have no more time for that !

[JM-Teule]

The share is running int shell but not in graphic way !

[matt335672]

I'm sorry @JM-Teule. I'm not trying to upset you, but I have to think about the other users we have who read these forums. Videos make it very hard for anyone searching for information to find it. They also have an annoying habit of disappearing so these issues no longer make sense to anyone in the future.

If we can work together using text to solve this, everybody benefits.

If the shell is working fine, but the GUI application isn't there must be a simple solution to this.

I don't think it's an xrdp problem as such. xrdp just presents the files over the network in a particular directory - that's how we test it. It has no interface at all with any graphical components.

However, I can think of a possible way this could happen. There could be a race condition between the filesystem mount and the client connection.

If your file manager is managing to open the My_LC directory before xrdp mounts the filesystem, the file manager would see an empty directory.

Can I ask you some more questions :-)

• Has your file browser pcmanfm changed as well?
• Have you got My_LC in any favourites folder on pcmanfm? If so what happens when you remove it?
• Are you able to restart pcmanfm after the client connection is made?
