Hi... I am currently using iptables (1.2.5) and libipq to develop a user program (using the QUEUE target) that would introduce an extra delay for packets going through a bridge (bridge-utils-0.9.5). While using ping, the program works fine. But when i test it with Microsoft Netmeeting to transmit voice (no video yet), i quickly receive a message as below:-
read(): Failed to received netlink message: No buffer space available my program ended with the message above. My questions: [1] how big is this buffer? [2] how can i go about to solve this problem? I typically need to introduce a round-trip delay of 500ms (i.e. 250ms from src to dest through the bridge)? [3] can i do anything to enlarge this buffer? Thank you in advance.
