snmp - How to create SNMPv1 community string?

Question

I'm currently working on SNMPv1 and I'm wondering how to define a community string generally on my server.

Using snmpset and snmpget, I have to specify a community name, but I can only use community names that are registered somewhere, like public or private. How can I add one?

Thanks in advance!

The most detailed guide on how to configure SNMP agents on common UNIX or Linux system is from Essential SNMP book,

http://docstore.mik.ua/orelly/networking_2ndEd/snmp/ch07_03.htm

Under 7.3.4. Net-SNMP (Formerly UCD-SNMP) you can find the steps and it applies to all systems that uses Net-SNMP. That's why @PP. asks you to check /etc/snmp/snmpd.conf, which is the Net-SNMP configuration file.

My personal suggestion is that you directly go to 7.3.4.2. Creating a configuration by hand and create the config file by hand. Then you can easily set rwcommunity and rocommunity. That's the community names you would like to set.

If you do have time later on, make sure you go through this small book, as it does include most of the details about SNMP you should be aware of.
