Lately i'm having problem with udp masq entry in my internet leaf-router with a lot of messages like this: IP_MASQ:ip_masq_new(proto=UDP): could not get free masq entry (free=36864) here's my network looks like : ------------- ----------------------- |leaf-router| |RH9 squid & dnscachex| to -----|eth0 eth1|---|HUB|--|eth0 eth1| internet| | | | ------------- ----------------------- | | |switch| | | | subnet A - | | | subnet B --- | | subnet C ------| everytime i stop dnscachex, the messages also stop. am i having dns abuse from my internal network? or is it because there are too many clients in my internal network? how do i deal with it? any suggestion will be very appreciated. regards, gregor __________________________________ Do you Yahoo!?
