About the only thing I can think of off the top of my head. There might
be some sysctl option to disable UDP, but I dont know it if it does

How come tcpdump output is seeing all the udp syslog-ng messages?<br>

[root@aspsyslog ~]# /etc/init.d/syslog-ng start<br>

if the problem is before it gets to syslog-ng or after. Shut syslog-ng

out all traffic received. If it gets it, the problem is syslog-ng, if
it doesnt get it the traffic is getting blocked somehow.</font></font><br>
