[jason1987]

One of my host's states the above message. This is my first pre-compiled 2 agent, so I extracted it, placed the scripts in relevant places (/sbin/zabbix-agentd and /usr/local/etc/zabbix-agentd.conf) configured as I have previously;

Server:

* [root@XXX ~]# ncat -v xx.xx.xx.xx 10050
Ncat: Version 5.51 ( http://nmap.org/ncat )
Ncat: Connected to xx.xx.xx.xx:10050

* Log Doesn't mention the host in question.

* In the WebUI the hostname, IP and port match.

Host:

*root@XXX:/usr/local/etc# netstat -ntl|grep 10050
tcp 0 0 0.0.0.0:10050 0.0.0.0:* LISTEN

* :/usr/local/etc# vi zabbix_agentd.conf
Server=xx.xx.xx.xx #matches server
ServerActive=xx.xx.xx.xx #later added for troubleshooting matches server
StartAgents=0 #troubleshooting
Hostname=XXX #matches hostname in WebUI config

DebugLevel=4 #Troubleshooting
Timeout=9 #Troubleshooting


There the relevant checks I've done, I done understand the system 100% so please make allowances.

Any help greatly appreciated.
