How to disable clipboard redirection for my users from their local systems in xrdp

I am an administrator of the Ubuntu Server. I have 7 users. They log in through RDP. So I need to disable the clipboard from their local machine to the remote system. How to achieve this?

Ubuntu 20.04.3 LTS.

Solution 1:

By default, xRDP indeed will allow clipboard redirection and drive redirection. If you edit the following file

/etc/xrdp/xrdp.ini

Scroll through the file and locate the section

[Channels]

You will see something like this

[Channels]
; Channel names not listed here will be blocked by XRDP.
; You can block any channel by setting its value to false.
; IMPORTANT! All channels are not supported in all use
; cases even if you set all values to true.
; You can override these settings on each session type
; These settings are only used if allow_channels=true
rdpdr=true
rdpsnd=true
drdynvc=true
cliprdr=true
rail=true
xrdpvr=true
tcutils=true

Change value to false for the cliprdr (clibpoard redirection) and rdpdr (drive redirection). So, your file should look like this

[Channels]
; Channel names not listed here will be blocked by XRDP.
; You can block any channel by setting its value to false.
; IMPORTANT! All channels are not supported in all use
; cases even if you set all values to true.
; You can override these settings on each session type
; These settings are only used if allow_channels=true
rdpdr=false
rdpsnd=true
drdynvc=true
cliprdr=false
rail=true
xrdpvr=true
tcutils=true

Then restart your xrdp service to use the new settings.

Hope this help Till next time See ya
