[syslog-ng] Syslog-ng not receiving messages

[keshava V]

Looks like it is getting blocked somewhere as you thought. How come tcpdump
output is seeing all the udp syslog-ng messages?

[root at aspsyslog ~]# /etc/init.d/syslog-ng start
Starting syslog-ng:                                        [  OK  ]
[root at aspsyslog ~]# /etc/init.d/syslog-ng stop
Stopping syslog-ng:                                        [  OK  ]
[root at aspsyslog ~]# nc -u -l 514

getting nothing...!
