Hi Team,

I am seeing an issue where NCPA is not running on a linux machine shows status as active(exited).
ncpa listener logs show error as "[Errno 97] Address family not supported by protocol".
Can you help in resolving the issue.

Hi

Hi

In your /usr/local/ncpa/etc/ncpa.cfg please change or add
ip = 0.0.0.0

and restart the ncpa_listener service
service ncpa_listener restart

Let me know the result. If you are still having problems please include a fresh copy of ncpa_listener.log as well as
your /usr/local/ncpa/etc/ncpa.cfg file.

Thanks

Hi,
