Looks like it is getting blocked somewhere as you thought. How come tcpdump output is seeing all the udp syslog-ng messages?<br><br>[root@aspsyslog ~]# /etc/init.d/syslog-ng start<br>Starting syslog-ng: [ OK ]<br>
[root@aspsyslog ~]# /etc/init.d/syslog-ng stop<br>Stopping syslog-ng: [ OK ]<br>[root@aspsyslog ~]# nc -u -l 514<br><br>getting nothing...!<br><br><br><br><div class="gmail_quote">

<font size="-1"><font face="Helvetica, Arial, sans-serif">Ok, lets see
if the problem is before it gets to syslog-ng or after. Shut syslog-ng
down and do 'nc -u -l 514' and see if it gets anything. That'll dump
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>
