@derelict Derf, yep I mentioned the kernel version. The TNSR version is 21.07.0-1.
Anyway, sudo clixon_cli worked to get the commands operational (and that's using my custom user, not tnsr)
[Now I see the part of the docs that caused this issue, since I created a custom user during install:
Default TNSR Permissions where only root and tnsr users are allowed into the CLI.
For others' reference, here's how to fix that (once in the CLI via sudo):
configure t
nacm group admin
member USERNAME
exit
configuration copy running startup
exit
More info on NACM config here in the docs
After that, just entering clixon_cli without sudo will work just fine...
