Active agent/server port 80

[thysk]

Hi all

I want to setup my active agents to communicate with the Zabbix server over port 80, I have tried to configure my server to listen on port 80 but it won’t start with this setting.

/etc/zabbix/zabbix_server.conf
ListenPort=80

Has anybody done something like this before and are there any issues with this I need to consider when monitoring servers over the internet ?

As port 80 is used for HTTP i guess you might run into various problem.

And the server not startin while listening on port 80 is mostly due to a webserver allready listening on this port. Any logs?

I have configured Apache to listen on 8080 so that should not be a problem. Unfortunately it does not write anything to the /var/log/zabbix/zabbix_server.log even when its set to debug level 4.

In the config file is does state the following range...
### Option: ListenPort
# Range: 1024-32767

The system starts fine when its configured on any port on that range but it wont start on port 80..

How do you start the server? Through a script or directly? I found that if started directly if gives some more debug info.

check netstat -tulpn or ss -pan to see if there is something allready listening on port 80
