SnmpHelp

Some help on getting snmpd running on a PTP Node.

What is snmpd?

snmpd is a SNMP (Simple Network Management Protocol) daemon that responds to requests for information about a host and responds with that information. Many different types of information can be returned, including information about processes running, disk space, load average, uptime, and bandwith usage.

Why would I want snmpd running on my PTP Node?

To measure bandwith usage. Setting up snmpd allows you to be included on [http://www.personaltelco.net/mrtg/ this MRTG-like page], which shows the bandwidth utilization for various PTP nodes.

How do I configure snmpd to allow PTP to measure bandwidth usage?

(These instructions are for [http://net-snmp.sourceforge.net Net-SNMP] running on Linux.)

snmpd can be restricted in various ways. For example, it can be restricted so that it doesn't respond to requests from outside a LAN, or so that it only responds to request for certain types of information and not others.

We're going to configure snmpd so that it only responds to requests from bone.personaltelco.net and provides read-only access to all information. In just 3 easy steps...

• 1) Choose a "Community Name" that acts like a password. (The default is "public".)

  2) Add the following line to your snmpd.conf file, (replacing <Community Name> with your actual community name).

  • {{{rocommunity <Community Name> bone.personaltelco.net

}}}

• 3) Restart snmpd.

I configured snmpd and it's running. Now what?

Contact TomOffermann and send the following information:

• 1) The IP address or domain name of your node. (Must be publicly accessible, of course.) 2) The port that snmpd is running on. (Port 161 is the default.) 3) The community name you chose.

Once I receive your information, I'll add you to the system and you'll soon see your node's bandwidth usage on http://www.personaltelco.net/mrtg/.
