I'm having a heck of a time to get this command to work.
On all of the sub commands I'm getting this error
Error: Operation not supported
Debugging the "nfsdctl listener" command
the nl_recvmsgs() erroring out with -95
I'm assuming "nfnetlink" is the module
and it is loaded.
Something is missing... for all the commands
to fail like that... Not clear to what it is.
steved.
