Hello,

I am trying to get the Dell Troubleshooting Tool for OSMA to connect correctly to openSUSE systems via SNMP.  The error I am receiving is:

The SNMP read request has failed for Get Community name - this-domain

I cannot figure out where to change the community name on the SUSE system.

Please advise.

Thank you,

Don

If you have installed net-snmp-utils (which installs the snmp daemon 'snmpd', the config file is under /etc/snmp/snmpd.conf
The line you are looking for is
rocommunity public
Change "public" to whatever you want the ro community, restart snmpd.

If you have not installed net-snmp-utils, you can do so with the command
zypper install net-snmp-utils

I have net-snmp installed.  When I try to install net-snmp-utils I receive the error:

Package 'net-snmp-utils' not found

I don't have a SUSE box here to test directly, but I do believe net-snmp includes the -utils and phyton, from what I"m seeing.

Do you have a service named "snmpd" and an snmpd.conf? Usually found under /etc/snmp/snmpd.conf

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Yes and I set rocommunity to the proper name, but it is still not working.

Are you getting the same read request error? And you did restart the snmpd service to re-read the config, right? (Sometimes it's the little things...)

DO you have a firewall blocking ports 161-162?

Can you locally poll?
snmpwalk -v2c -c communityname localhost?

If that provides you a response, this means you have a software firewall blocking access to udp/TCP port 161
Open the port on the software firewall.

I had the rocommunity set at name 127.0.0.1.  Set to name only then it worked!  Thank you!
