Has anyone any idea on how to read packets from user space which are queued by setting rule in iptables with target as QUEUE in Colibri imx6 ?
I want to use QUEUE as target in iptables rule and later read the packet in user space through API library like netfilter queue. However, I am not able to find libnetfilter_queue header files and library. iptables is present and I am able to set rule for target like QUEUE. How to fetch these queued packets from user space ?
My systems details are as follows.
Colibri iMX6DL 512MB
Colibri Evaluation Board V3.2
Linux Kernel v4.9.220 - Angstrom distribution
Here we need more details to understand issue. Are you not able to compile application with libnetfilter_queue?
Have you compiled SDK with the library included ?
At the moment we do not have any sample code for same that said, this is not specific to Colibri and rather general Linux specific question.
Thanks for the reply.
I am able to compile and generate exe using libnetfilter queue. However, upon execution of exe, response is as similar to the one, which we get for non root user. I checked output of non-root user on development PC and root user on Colibri board.
