[Linux-Client] use device failed from cli

Submitted by yair.asraf on #1

HI,

I have virtual here linux server that run on private lab network,

and i have anather server that trying to use a device...

 

I'm running the command for using a device - 

labuser@yaira-lab:/etc$ /usr/sbin/vhclientx86_64 -t "USE,labpc.1311"
 

But getting 'FAILED'

didnt see any logs in virtual here servers that indicate that i try to connect the device.

Maybe i need to open other ports in the firewall for connect to device ? (except  7575)

You need to purchase a license

Hello,

I've bought and activated a license, restarted both the server and client. However, when trying to connect to device from linux client, I still encounter a 'FAILED' error with no corresponding logs on the server.

labuser@yaira-lab:/etc$ sudo /usr/sbin/vhclientx86_64 -t "USE,labpc.1311"
FAILED

(Note: I successfully executed list commands on the Linux client.)

Additionally, I've successfully connected to multiple devices from the Windows client command prompt.

Have a look in /var/log/syslog on the client machine where you are running vhclientx86_64 USE ... and see if it shows messages there

I cant see 

vhci_hcd            
usbip_core  

modules listed. Did you install usbip client drivers? ubuntu comes with those by default

Is this a normal install of ubuntu, or is it locked down somehow? E.g selinux rules

The reason is that the virtualhere client creates a linux domain socket (a special socket but just in memory) to talk to the usbip client driver

When it tries to then bind to this socket it fails with the error you have.

Can you send me the output of

sudo lsof -p `pidof vhclientx86_64`

Now i see that when i'm running sudo /usr/sbin/vhclientx86_64 (not in deamon), I'm getting this error when i trying to use a device -

labuser@yaira-lab:/etc/systemd/system$ sudo /usr/sbin/vhclientx86_64 -a
The VirtualHere Client drivers could not be loaded.

Try rebooting your machine and running VirtualHere Client again.

(I tried to reboot the mechine and it didn't help)

 

What virtual here drivers sould be installed ?

Thanks for the help

 

***After Edit -

I can see error in cat /var/log/syslog -

What about if you uninstall the virtualhere client service 

Reboot, then open a terminal and type

sudo ./vhclientx86_64 -n

then

./vhclientx86_64 -t "USE,labpc.1311"

Does that work?

I Can't belive it but i find the issue.

I'm Running on the same linux PC Digi client (It's a different tool that provide solution for remote serial)

And when Digi client are running, virtual here failed to connect with error: VirtualHere Client: bind unix domain socket server, error 98 (Address in use).

But when DIgi client are not running virtual here client 'USE' command is working.

Probebly they both run on the same socket, do you have a solution for that ?? can i configure a different socket address ?

I need the digi & virtual-here clients to run parallel 

 

Thanks.

Ah OK! Yes digi licensed virtualhere a while ago for their digi anywhere plus product. So their client is actually a custom version of virtualhere client, so you wont be able to run both on the same machine.
