About

LibreNMS has an easy to use IRC-Interface for basic tasks like viewing last log-entry, current device/port status and such.

By default the IRC-Bot will not start when executed and will return an error until at least $config['irc_host'] and $config['irc_port'] has been specified inside config.php.

If no channel has been specified with $config['irc_chan'], ##librenms will be used. The default Nick for the bot is LibreNMS.

The Bot will reply the same way it's being called. If you send it the commands via Query, it will respond in the Query. If you send the commands via a Channel, then it will respond in the Channel.

Examples

Server examples:

Unencrypted Connection to irc.freenode.org:

   ...
   $config['irc_host'] = "irc.freenode.org";
   $config['irc_port'] = 6667;
   ...

SSL-Encrypted Connection to irc.freenode.org:

   ...
   $config['irc_host'] = "irc.freenode.org";
   $config['irc_port'] = "+6697";
   ...

SSL-Encrypted Connection to irc.localdomain with Server-Password and odd port:

   ...
   $config['irc_host'] = "irc.localdomain";
   $config['irc_port'] = "+12345";
   $config['irc_pass'] = "Super Secret Passphrase123";
   ...

Channel notations:

Channels can be defined using Array-Notation like:

   ...
   $config['irc_chan'][] = "#librenms";
   $config['irc_chan'][] = "#otherchan";
   $config['irc_chan'][] = "#noc";
   ...

Or using a single string using , as delimiter between various channels:

   ...
   $config['irc_chan'] = "#librenms,#otherchan,#noc";
   ...

Extensions?!

The bot is coded in a unified way. This makes writing extensions by far less painful. Simply add your command to the $config['irc_external'] directive and create a file called includes/ircbot/command.inc.php containing your code. The string behind the call of .command is passed as $params. The user who requested something is accessible via $this->user. Send your reply/ies via $this->respond($string).

A more detailed documentation of the functions and variables available for extensions can be found at IRC-Bot Extensions;

Confused? Here an Echo-Example:

File: config.php

   ...
   $config['irc_external'][] = "echo";
   ...

File: includes/ircbot/echo.inc.php

   //Prefix everything with `You said: '...'`  and return what was sent.
   if( $this->user['name'] != "root" ) {
      return $this->respond("You said: '".$params."'");
   } else {
      return $this->respond("root shouldn't be online so late!");
   }
