Cannot connect to [my_agent] [Connection refused]

I've went through the forums and tried to solve my problem, but I can't get past it. I'm trying to use the Unix_t template, the SNMP template_works for another host, I can telnet to the machine using port 10051, netstat shows it listening, zabbix_server is running along with the agent daemon, and I've checked iptables and there is no firewall running. Here are my config files.

Any thoughts?

It looks like the agent on the host is set to listen on port 10050, in zabbix on the host configuration screen for this particular host, do you have the same number listed in the port box there?

Hostname

I do not know if this matters or not.

I noticed that in your posted conf file, you have

hostname=my_zabbix_server.com

I believe that the hostname it is looking for is the local hostname, not the hostname of the server. Try changing it to:

hostname=client_hostname

Make sure that the hostname is listed in the local /etc/hosts or that the client can resolve the hostname to the client IP address.

That actually shouldn't be giving the error he is getting, but if he wants to do any active checks, that's when that must be set correctly.

Yes, the Port is 10050.

Still having problems with this. As I understand it, my zabbix_server is working fine. The problem is with the agent. I start the agent and it creates the zabbix_agentd.pid, but when I run ps aux | grep zabbix(or zabbix_agentd) nothing shows up.
