Update: still valid for 18.04
Where are the MIB files ?
I’m in the middle of upgrading old servers but it was just only yesterday that I found Ubuntu 12.04 didn’t install the MIB files. Even if you install the SNMP applications. It was really strange to launch
tkmib and just see a couple of nodes.
The explanation is simple. Just check the preamble of
# # As the snmp packages come without MIB files due to license reasons, loading # of MIBs is disabled by default. If you added the MIBs you can reenable # loaging them by commenting out the following line. mibs :
Sure, but how can I install them ?
Fortunately there is a package to deal with that.
$ sudo apt-get install snmp-mibs-downloader
It will download the IETF MIB files and install them under the usual
If for any reason you don’t see it happen force it with
$ sudo download-mibs
You can repeat this command later to update any new MIB file.
Well, almost. At this time your tools still won’t work correctly. Just remember the text on
/etc/snmp/snmp.conf. You have to comment out the
mibs : line! Now everything is by the book. Enjoy!
