MariaDB > create user identified by 'sekritpass' This is normal, and I will not repeat this line below.Ĭreate the database user we will use to log traps with, and give that user all rights to tables in that database: After every successful command you give the database engine, you will get a line stating Query OK, xxx row affected (0.03 sec). You can add that terminating semicolon at the ' ->' prompt. Always terminate an sql command with a ' '. If you end up with a ' -> ' prompt, you have forgotten the terminating semicolon in the command above. Keep the database name ' net_snmp' for the purpose of logging traps. Type '\c' to clear the current input statement.Ĭreate the database we will log traps to: Server version: 5.5.44-MariaDB-1ubuntu0.14.04.1 (Ubuntu)Ĭopyright (c) 2000, 2015, Oracle, MariaDB Corporation Ab and others.

When prompted, provide the password you gave during install of MariaDB. Now, we need to create the database the traps will be stored in, as well as the database user we will use when logging mysql -u root -p We don't need snmpd at the moment, so we will stop and disable sudo service snmpd sudo update-rc.d snmpd disable The command above adds mysql and snmpd to your default services, and starts them both. The names of the binaries and the startup-scripts are the same for MySQL and MariaDB. I choose MariaDB over MySQL, as MariaDB had support for an option not present in the version of MySQL available to me at the moment. MariaDB is a drop-in replacement for MySQL. Writing the admin user and password down and keeping it in a safe place is a good idea. Note that MySQL/MariaDB both use an internal user database, unrelated to the system userdatabase. You will be prompted for an admin user/password etc. Then, I logged in and sudo apt-get install mariadb-server mariadb-client snmp snmpd snmp-mibs-downloader I got my friendly sysadmin to spin up a virtual Ubuntu machine for me. A link to suggested reading materials is provided at the end.

The trap receiver typically runs on a server.

The agent typically runs on a piece of network equipment, like a router, switch, firewall or even a server. An SNMP agent is a process which can be queried (read) and possibly configured (write), as well as emit traps ('alerts') directed at an SNMP trap receiver.It is more like a username, for which there is no password. Having no write community enabled until you really need it, it is a good idea. It is common to have separate SNMP communities for read and write access to an SNMP agent.See your friendly firewall admin for advice. An adversary can flood spoofed packets from anywhere. Easily eavesdropped upon, easily spoofed. SNMP version 1 and 2c are not encrypted protocols.The following is an account of how I get the messages into a database, and how I can query the database to extract the information I want.īefore we start, y ou should be aware of a few important things with regards to SNMP: The wireless controllers already emit a huge stream of SNMP traps to another network device which makes use of them to match usernames with IPaddresses. Can I make a simple tool that assists superusers and the servicedesk in simple debugging of wireless access clients? And we'd rather not let more users have access to these tools than strictly required. But they are not extremely user friendly. Our provider of wireless network gear got tools to manage the wireless network, which may or may not assist with counting devices per user.

Ideally, we would give users nice feedback. Because they are not aware of the limit, because they have forgotten about one or another device in their backpack, or because someone is abusing the account in question. Hence they will call servicedesk to request help getting their device on the network. But whenever a user tries with a third, there is no useful feedback to the end user that the number of devices has been exceeded. The reason for the request is that we enforce a maximum of two devices per user. "How can our servicedesk count the number of devices a user has on our wireless network." I recently got a request formulated approximately like this:
