Hello everyone,

I'm working on a program that uses libnetfilter_queue, and after the program crashes or I have to kill it I get the following error starting up:

NFNETLINK answers: File exists
Error during nfq_bind_pf(): File exists

Rebooting fixes it so I guess the netlink socket in question is a "virtual" one. What I'd like to know is how to clear this error without rebooting?

Thank you for your help,

João Valverde

Could you post the code of your program?
