Because the log is dumped in a file, sometimes the IP address is incomplete and will be inserted in cbq file as it is. In this case the network coresponding to the IP will be shaped (see cbq docs for more). My recomandation is to have a cbq file cbq-0105.netadmins (as is in tar.gz file) that contain all your netadmin IP. In this way you will not be affected if the p2p_grab script fail to extract the IPs.
The following is a fail log inserted in cbq-0200.kazaa_users file:
--- start cbq-0200.kazaa_users file ---
DEVICE=eth0,100Mbit,10Mbit
RATE=32Kbit
WEIGHT=3Kbit
PRIO=5
RULE=192.168. # wrong (incomplete) IP dumped !!!
--- end cbq-0200.kazaa_users file ---
The above line (RULE=192.168.) means that all 192.180.0.0 networks are shaped which is not good because we want to insert only individual IPs and not networks!!! My opinion...
In case that you do not have a cbq file for netadmins and if you're in the same network (192.168.0.0) you will be shaped as well.
