The If the up.time Linux agent has a built-in daemon option that allows users to run the up.time agent without (x)inetd installed on their server. The daemon allows access to be restricted to a specific hostname belonging to the up.time monitoring station as detailed belowAgent is managed by xinetd (default option), it is possible to limit access to the Agent with xinetd's "only_from" parameter. Setting only_from parameter to the up.time Monitoring Station hostname or IP address will restrict any other system from issuing requests to the up.time Agent.
To implement, update the /etc/xinetd.d/uptimeagent configuration file and add the following line at the end.
| Code Block | ||
|---|---|---|
| ||
/opt/uptime-agent/bin/uptmagnt-daemon -p <port> -b <hostname> | ||
only_from = uptime_ms |
If using an IP address, the only_from line is similarAn example launch may look like this:
| Code Block | ||
|---|---|---|
| ||
/opt/uptime-agent/bin/uptmagnt-daemon -p 9998 -b my.uptime.host.com | ||
only_from = 10.1.1.1 |
With the /etc/xinetd.d/uptimeagent configuration file updated, restart the xinetd service to read in the changeA common error is to include uptimesoftware.com in the bind option. For example, the launch command below incorrectly binds the agent daemon to only accept connections from uptimesoftware.com.
| Code Block | ||
|---|---|---|
| ||
/opt/uptime-agent/bin/uptmagnt-daemon -p 9998 -b uptimesoftware.cometc/init.d/xinetd restart |
Now, only the up.time Monitoring Station system can access the up.time Agent.
