MIBS problem

Post by MPIvan »

Hi all

sorry for opening similar posts but i think that this topic should have separate post.

Here is what i think more of us have this kind of problems. Im using Ubuntu server 12.04 LTS and I was following the tutorial of NET-SNMP and i have this errors and problems that i can't figure out what is going on and what is the problem ... so if you can gave me some hints or help me to solve this arrogant problem :evil: i will be very thankful !
here is the problems and errors i have ....
root@nagios:/usr/share/mibs/netsnmp# net-snmp-config --default-mibdirs
/root/.snmp/mibs:/usr/share/mibs/site:/usr/share/snmp/mibs:/usr/share/mibs/iana:/usr/share/mibs/ietf:/usr/share/mibs/netsnmp
root@nagios:/usr/share/mibs/netsnmp#

in more cases i have this error about MIB search path ... and in the first paragraph i can't understand tha MIBS path that i get from the "net-snmp-config --default-mibdirs" command. Because when i try to find the MIBS i have this

/usr/share/mibs
/usr/share/snmp/snmpconf-data/snmp-data/mibs
/var/lib/mibs

and this lines i can't understand ....

Hmm so it seems that snmptranslate is looking in paths that either do not exist or are not default paths for mib placement in ubuntu. Have you tried symlinking one of the non existing directories to one that ubuntu uses?

Hi sreinhardt,

Paths like exist
/usr/share/mibs/iana
/usr/share/mibs/ietf
/usr/share/mibs/netsnmp

well considering you would want this to run as nagios you would really want /home/nagios/.snmp/mibs. However lets start by listing the existing directories and seeing what we find. Symlinking is a common practice in Linux that allows you to create a link in one folder to another actual folder. This allows you to appear to duplicate files and information without taking up more space.

Code: Select all

ls -la /usr/share/mibs/iana
ls -la /usr/share/mibs/ietf
ls -la /usr/share/mibs/netsnmp

OK so /usr/share/mibs/netsnmpp looks like the folder to place mibs in and it seems that at least for testing, your permissions are fine. Lets try a grep through your existing mibs to see if they contain the oids you have been looking for.

Code: Select all

cd /usr/share/mibs/netsnmp
grep -i 'iso.3.6.1.2.1.1.3.0' ./*
grep -i '.1.3.6.1.2.1.1.3.0' ./*
grep -i 'sysUpTime' ./*

OK, so you do have the sysUpTime short name for oid .1.3.6.1.2.1.1.3, however you are adding an additional 0 to the end which for my mibs gois to a DISMAN-EVENT-MIB that I do not see listed in your mib directory listing. Also note how none of the oid numerical greps resulted in anything. Just to verify 100% snmptranslate sees sysUpTime try this:

Code: Select all

 snmptranslate .1.3.6.1.2.1.1.3
Should return something like:
SNMPv2-MIB::sysUpTime
