How to get this snmp value?

[kenlok]

IP-MIB::ipAdEntAddr.161.33.46.73 = IpAddress: 161.33.46.73
IP-MIB::ipAdEntAddr.192.168.10.254 = IpAddress: 192.168.10.254
IP-MIB::ipAdEntAddr.192.168.55.254 = IpAddress: 192.168.55.254

161.33.46.73 is a dynamic wan IP.
How can I get this value in zabbix?

Thanks

I am looking into that as well. The issue is with the snmpget.

Is there anyway in Zabbix to use snmpgetnext?

Example:

snmpget -On x.x.x.x -c public -v 2c .1.3.6.1.2.1.4.20.1
.1.3.6.1.2.1.4.20.1 = No Such Object available on this agent at this OID

AND:

snmpgetnext -On x.x.x.x -c public -v 2c .1.3.6.1.2.1.4.20.1
.1.3.6.1.2.1.4.20.1.1.x.x.x.x = IpAddress: x.x.x.x

Ideas?

So this is so far what I tested:

snmpwalk returns:

IP-MIB::ipAdEntAddr.x.x.x.x = IpAddress: x.x.x.x

I was reading:

https://www.zabbix.com/documentation/2.0/manual/config/items/itemtypes/snmp/dynamicindex

So I tried:

IP-MIB::ipAdEntAddr["index","IP-MIB::ipAdEntAddr","IpAddress"]

However, I get NOT FOUND error.

I create a shell script to get the value
It will return the WAN IP

######################################
#!/bin/bash

qq=$(/usr/bin/snmpwalk -v 2c -c public $1 ipAdEntAddr | awk -F" " '{print $4}')
arr=$(echo $qq | tr " " "\n")

for x in $arr
do
FirstIp=$(echo ${x:0:3})
if [ "$FirstIp" -ne "192" ]
then
echo $x
fi
done

Thanks for the post! I was thinking to write a script too, but that's only a workaround.

Does anyone know why this returns not found error:
IP-MIB::ipAdEntAddr["index","IP-MIB::ipAdEntAddr","IpAddress"]

As per the guide below, it should be working.

Can anyone tell me if it is a bug?

As per:

https://support.zabbix.com/browse/ZBX-4793

snmpwalk returns:

snmpwalk -v 2c -c public x.x.x.x ipAdEntAddr
IP-MIB::ipAdEntAddr.x.x.x.x = IpAddress: x.x.x.x
IP-MIB::ipAdEntAddr.x.x.x.x = IpAddress: x.x.x.x
IP-MIB::ipAdEntAddr.x.x.x.x = IpAddress: x.x.x.x
IP-MIB::ipAdEntAddr.x.x.x.x = IpAddress: x.x.x.x

The first entry should be found and used.

Anyone?

Now I am sure this is a bug with Zabbix. Unfortunately I do not know how to re-open that bug or get more visibility on it.

Thanks for the bash script. My workaround is a little different:

In zabbix_agentd.conf I added:

UserParameter=public.ip,snmpwalk -v 2c -c public -On 192.168.1.1 ipAdEntAddr | grep -v "IpAddress: 127" | grep -v "IpAddress: 169" | grep -v "IpAddress: 192" | awk '{print $4}'

I created an item in zabbix and trigger for it which flags if the IP changes.
