Hello All
I am trying to get vna-qt program in linux to connect to my SAA2.
I have loaded the software into my win 10 machine and it works fine with the vna.
I have vna-qt running in ubunto linux but when I try to connect to it, it gives me an error message dialog box which reads:
"Exception
Permission denied"
Any ideas what may be wrong?
Thanks in advance.
Cheers

Is the username (you are logged in as) a member of the "dialout" group?

If you look at /dev/ you can probably find it, and see the permissions for the comm port.? Typically, serial ports (and emulations thereof) are "owned" by dialout.? The default permissions on /dev/tty{whatever} are read for everyone, rw for the group.


you can also run python as superuser (sudo python nanovna_saver)

Example for

$ls -al /dev/tty*

crw--w---- 1 root tty?????? 4,? 8 Nov? 8 08:17 /dev/tty8
crw--w---- 1 root tty?????? 4,? 9 Nov? 8 08:17 /dev/tty9
crw-rw---- 1 root dialout 204, 64 Nov? 8 08:38 /dev/ttyAMA0
crw------- 1 root root????? 5,? 3 Nov? 8 08:17 /dev/ttyprintk

Thanks for the tip.
It is working now.
Cheers
