I have a IPv6 only router and i want to connect my monitoring system with the router. So i need SNMP enabled.

A short netstat shows: ‚NO ONLY IPv4‘ :/

root@router1337:~# netstat -taunp | grep 161
udp 0 0 0.0.0.0:161 0.0.0.0:* 14039/snmpd
root@router1337:~#

The Config File is /etc/config/snmpd (normal linux will have the same settings – but differnent location):

root@router1337:~# cat /etc/config/snmpd

agentaddress udp6:161
rocommunity6 HOMEDIRRO1337 2a04:4f8:cccc:aaaa::1

2a04:4f8:cccc:aaaa::1 is the ip of the monitoring server (query host with snmpwalk/get)

Success:

root@router1337:~# netstat -tanunp | grep 161
udp 0 0 :::161 :::* 14219/snmpd
root@router1337:~#

*HAPPPPY*

BTW:

How to install:

opkg update

opkg install snmpd

Short log of how to debug the start:

root@router1337:~# /usr/sbin/snmpd -Lf /tmp/snmpd.log -f -c /etc/config/snmpd &
root@router1337:~# cat /tmp/snmpd.log
