This module is used to remove conntracks under different criteria.

Usage: Remove conntrack matching tuple.dst, presented as network-endian. FORMAT: "proto:ip:port" proto: 0 for UDP, 1 for TCP. The total string length would always be 16 bytes(extra ' ' appended).

bash> insmod dummy_rmct or bash> insmod dummy_rmct clearance_interval=10 clearance_interval is interval in second to do the clearance.

Add a criterion. bash> echo '1:0a07c906:0050' > /proc/rmct_list Which is to match destination as "TCP 10.7.201.6:80"

Once module proceeds criteria. It'll then remove them.

See what's been add but has not been removed bash>cat /proc/rm_list

bash> rmmod dummy_rmct

BUILD: I build and test it under kernel 2.6.26. bash> cd /path/to/module-source/ bash> echo "obj-m += dummy_rmct.ko" > Makefile bash> make -C /usr/src/linux/ M=/root/src/dummy_rmct modules
