Include Asterisk SNMP MIBs in build by default

[tmo]

It seems that all the piaf versions do not include asterisk snmpd support. This is rather unfortunate as it requires one to rebuild asterisk at each update if the functionality is desired.

CLI> module show like snmp
Module Description Use Count
0 modules loaded

looks like other flavors are mostly built "–with-snmp" ...

Please consider this.

I'll second that request.

I'll second it as well...

Can someone who has done it document the steps necessary? That'll save a bunch of time. Thanks.

Happy New Year to all.

When I get back in the office, I will more than gladly provide a step by step

For those that are not aware, SNMP v1 is a security risk as the only "authentication" is via a clear text community name that can easily be sniffed. So normally, SNMP v1 is only used for monitoring.

SNMPv2 combined the RMON (Remote Network Monitoring) MIB definition and Secure SNMP. Secure SNMP provides strong authentication and privacy mechanisms suitable for network management in a generally open environment.

In addition, SNMPv2 was extended to address the concerns over protocol efficiency and safety (acknowledgements of Trap). Two new protocol functions (PDUs) were added (GetBulk and Inform Request) to allow efficient reading of tables and provide reliable communications.

NOTE: SNMPv1 and SNMPv2 do not interoperate. The two versions must be translated to communicate with each other.

Current builds will require rebuiling with snmp modules, ie: "./configure –with-net-snmp" support enabled.

then, it's a simple matter of getting asterisk and snmp setup to use the mibs:

cp /usr/src/asterisk/doc/asterisk-mib.txt /usr/share/snmp/mibs/ASTERISK-MIB.txt
cp /usr/src/asterisk/doc/digium-mib.txt /usr/share/snmp/mibs/DIGIUM-MIB.txt
mkdir /var/agentx
touch /var/agentx/master
chown -R asterisk:asterisk /var/agentx
cp /etc/asterisk/res_snmp.conf.save /etc/asterisk/res_snmp.conf

Add the following lines to /etc/snmp/snmpd.conf:

master agentx
agentXperms 0660 0550 asterisk asterisk

Then restart snmpd and asterisk. Once complete, you can test it out using:

export MIBS=+ASTERISK-MIB
snmpget -v2c -c public localhost 1.3.6.1.4.1.22736.1.5.1.0
