USB forwarding from Debian 10 (Enterprise Client)

[gnoacco]

Hello everyone !

I’m a happy user of NoMachine since a few years, running it on different machines: PCs, Servers, RaspberryPis…
I’m encountering an issue with USB Forwarding from a Debian 10 (LXDE) – Enterprise Client (6.10.12), to a Debian 10 (LXDE) – NoMachine (6.10.12) server: when I’m connected to the remote desktop, and try to choose a USB device to forward to the server, the list of available local USB devices is empty.

But it works if I connect from a Windows 8.1 Enterprise Client.

For context:
– The nxusb.ko module is compiled, without error (it is in /usr/NX/bin/drivers/nxusb.ko), on the client and the server.
– The nxusb module is loaded without error (listed in lsmod)

When I inspect the session log on the client, I notice this error when I try to load the USB device forwarding list:
“3875 3981 08:52:44 606,568 DeviceIoUsbUnixClient: WARNING! Could not open lock file.”
I also noticed multiple errors:
“4212 4212 08:55:34 582 nxexecGetVarFromCfg: ERROR: Cannot open file ‘/usr/NX/etc/node.cfg'”
“4212 4212 08:55:34 582 ERROR: Cannot retrieve variable ‘EnableDebug’ from node.cfg.”
“4212 4212 08:55:34 582 nxexecGetVarFromCfg: ERROR: Cannot open file ‘/usr/NX/etc/server.cfg'”
“4212 4212 08:55:34 582 ERROR: Cannot retrieve variable ‘EnableDebug’ from server.cfg.”

And indeed, node.cfg and server.cfg are not in the /usr/NX/etc folder.

I’ve tried reinstalling NoMachine Enterprise Client multiple times, nothing changes.
Has anyone already encountered this issue ?
Do you know how to solve it ?

Thanks a lot

Hi,

I wasn’t able to reproduce the same issue on my Debian machine, and most probably it’s caused by some issue with user rights.

Can you please check the few following things?

1. Does this directory exists?

/usr/NX/var/run/nxusb/

This folder should have the following rights drwxr-xr-x

2. Does it contains “/usr/NX/var/run/nxusb/lock” file?

If the directory exists but there is no “lock” file, please try to create it manually and set the following rights: rw-rw-r–
