  Compiled with OpenSSL 3.2.2 4 Jun 2024

Operating system & version

Fedora 41

Installation method

dnf / apt / zypper / pkg / etc

Which backend do you use?

xorgxrdp

What desktop environment do you use?

KDE

Environment xrdp running on

KVM virtual machine

What's your client?

Windows 10 RDP client

Area(s) with issue?

File transfer / drive redirection

Steps to reproduce

  1. Fresh install Fedora 41 KDE spin
  2. Install packages: sudo dnf install -y plasma-workspace-x11 xrdp xorgxrdp
  3. Enable xorgxrdp in /etc/xrdp/xrdp.ini, then sudo systemctl start xrdp
  4. Login to this machine using Windows 10's built-in RDP client with a mapped drive
  5. Try to copy a file into ~/thinclient_drives/<YOUR_DRIVE> graphically using Dolphin

✔️ Expected Behavior

Copy succeeds

❌ Actual Behavior

Copy fails; Dolphin indicates no free space available on drive

Anything else?

This problem was mentioned in passing in #1429 (comment):

It seems like xrdp is always reporting 0 available space on mapped drives. KDE checks this value before the copy commences, hence the error. If we instead use a tool that doesn't check it (e.g. cp/mv), the operation would succeed.

There's no solution in xrdp at the moment I'm afraid, as we don't have the plumbing in place yet to query the remote file space. If you can disable the check in Dolphin, that would also work, but I don't know if that's possible.

See also #3246 where this issue is discussed.

Thanks for the swift response; that's good to know.

If you can disable the check in Dolphin, that would also work, but I don't know if that's possible.

This behaviour doesn't look like it's configurable, but I'll go consult KDE devs to be sure.
