Question how to enable snmp on redhat box

1. How to enable snmp on linux redhat 6.2 ? so i can take mrtg snap ? I am getting following error while trying to make mrtg.cfg file from my linux box's (NAT) nic card to monitor bandwidth utilization.

--base: Get Device Info on public@x.x.x.x:
SNMP Error:
receiving response PDU: Unknown error
SNMPv1_Session (remote host: "x.x.x.x" [x.x.x.x].x)

SNMPWALK Problem for on public@x.x.x.x::::::v4only

--base: Writing mrtg.cfg

seems like snmp is not configured on the to get it and start running on the server?

hope you have snmpd installed and running, Check with

#netstat -l

whether ports 161 is open.

If it is down,

#chkconfig --level 2345 snmpd on //will start snmp services every time your machine boots.
#service snmpd start

I had exactly the same problem setting up snmp on RH9 with a view to get MRTG working. MRTG is now working well, and it was worth the hassle... It was a while ago and I cannot remember of the top of my head exactly how I fixed it.

From what I remember...

You need to play around with the /etc/snmp/snmpd.conf file a fair bit to get it working, as the conf file (at least to me) does not seem to intuitive.

Here is the top part of my /etc/snmp/snmpd.conf

com2sec notConfigUser default public

group notConfigGroup v1 notConfigUser
group notConfigGroup v2c notConfigUser

view systemview included .
view systemview included .

com2sec mynetwork mycommunity

group MyRWGroup v2c local
group MyROGroup v2c mynetwork

group MyRWGroup v2c otherv3user

view mib2 included fc

access MyROGroup "" any noauth 0 all none none
access MyRWGroup "" any noauth prefix all all all

com2sec notConfigUser default public

com2sec notConfigUser default public

group notConfigGroup v1 notConfigUser
group notConfigGroup v2c notConfigUser

These top setting were the ones I played with most.

Dont foget to use snmpwalk when you are trying to get it working, again from what I remeber it gives you good debugging info

also dont forget to try public@localhost, public@ (or whatever) public@your.IP.add.ress

Hope this gives you some clues....
