Um. "lsof -P -c ossec-remoted" ? There should be a line like this:

ossec-rem 3378 ossecr    4u  IPv4  11436       UDP *:1514

which you should be able to get by being a bit more restrictive:

# lsof -P -a -i -c ossec-remoted
COMMAND    PID   USER   FD   TYPE DEVICE SIZE NODE NAME
ossec-rem 3378 ossecr    4u  IPv4  11436       UDP *:1514

Also, you say you checked logs. This includes /var/ossec/logs/ossec.log
too? That's where OSSSEC puts all its info, including any failure
messages.

Subject: [ossec-list] ossec-remoted not binding to 1514/udp?

Hello,

I believe I'm having an issue with ossec-remoted binding to port
1514/udp.


** Basic Configuration/OS Information **

OS: Linux <server_name> 2.6.32-27-server #49-Ubuntu SMP Thu Dec 2
02:05:21 UTC 2010 x86_64 GNU/Linux
ossec: 2.5.1

make setmaxagents
Specify maximum number of agents: 4096
./install.sh

/etc/security/limits.conf have the following entries (and server was
restarted afterwards):
*       soft    nofile  4096
*       hard    nofile  4096


** Issue Description **

As stated, it appears that while ossec-remoted is running, it is not
binding to 1514/udp.  I've been troubleshooting this and have not been
able to get any helpful information out of the logs, debug mode, or
stracing the process.


When I run a tcpdump, I see the agents trying to connect to the server
on 1514/udp, but the server responds back with the following:

ICMP <server_ip> udp port 1514 unreachable, length 109

Which indicates there's no process listening on the port. netstat does
not show 1514 in use.


I verified 1514/udp connectivity by utilizing netcat (nc) and
successfully connected to the server on 1514/udp.


strace show's the following for ossec-remoted:
recvfrom(4,


I have the following in ossec.conf with relation to remoted:
  <remote>
    <connection>syslog</connection>
  </remote>

  <remote>
    <connection>secure</connection>
    <allowed-ips>192.168.0.0/16</allowed-ips>
    <port>1514</port>
    <local_ip>(server_ip_address)</local_ip>
  </remote>


If there's any addtional information that might be helpful, please let
me know.

I've been researching using google but have found no resolutions to
this specific problem.  Any ideas?

Thanks in advance,
Patrick
