Server=10.0.10.183 (zabbix_server)

Check the IP address for your server. Try and telnet from the command line to the agent

telnet 10.0.2.66 10050

When you connect type "agent.version". It should return version information for the agent.

If that does not work that means the agent is rejecting the connection as the inbound IP address does not match the one it has for the server. If it does work then its possible the server is using a different IP address to originate the connection than the one used for your telnet test, this is only a problem for a multi homed host.

There are many posts regarding this problem in the forums, if you need further help just ask. :-)

i tried telnet to the agent ip address as you suggest and it returns like this

zabbixII# telnet 10.0.2.66 10050
Trying 10.0.2.66...
telnet: connect to address 10.0.2.66: Connection refused
telnet: Unable to connect to remote host

any other suggestions?thanks nelson..

That would mean that the agent is refusing the connection from the server. Did you bind the server to a different IP address than the one in the agent config? Is there a NAT firewall between the server and the agent? If so you'll have to use the NAT address of the firewall for the server IP in the agent config.

hanarina. i hope u can help me. bcoz we work the same thing.

[zabbli]

you can only connect to the server or IP which you have defined as listen address in the config file

[kasunmr]

Check the firewall?
