Enable remote SNMP access?

djkrite Nov 20, 2008 4:34 PM

Hello,

I'm running:

JBoss 4.2.2 and Java 5. I've been successful in setting up Cacti to get SNMP data from JBoss via, the snmp-adaptor on my local machine (localhost). However I have been unsuccessful get the data into Cacti from a remote JBoss server. How do enable remote SNMP access for the snmp-adaptor? Here is my current managers.xml:

<?xml version="1.0"?>
<manager-list>
 <manager>
 <address>localhost</address>
 <port>1162</port>
 <local-address></local-address>
 <local-port></local-port>
 <version>1</version>
 </manager>
 <manager>
 <address>192.168.1.1</address>
 <port>162</port>
 <local-address></local-address>
 <local-port></local-port>
 <version>1</version>
 </manager>
</manager-list>

Thank you,

TK

I was able to get this to work with iptables and some redirecting:

#!/bin/sh IPT="/sbin/iptables" INT="eth0" $IPT -F $IPT -F INPUT $IPT -F OUTPUT $IPT -F FORWARD $IPT -F -t mangle $IPT -F -t nat $IPT -X $IPT -P INPUT ACCEPT $IPT -P OUTPUT ACCEPT $IPT -P FORWARD ACCEPT $IPT -t nat -A OUTPUT -p udp -d 192.168.1.1 --dport 1161 -j REDIRECT --to-port 1161

I also removed the 2nd manager attribute listing in the managers.xml file.

You need to bind jboss to some visible IP, e.g.

run -b xx.xx.xx.xx

Ah, thank you. It worked! The above routing with iptables only worked for me when I was on the actual box. Seems "REDIRECT" option for iptables takes locally -generated packets and sends them to 127.0.0.1, so when I used snmpwalk from a remote box the command timed out.
