ReadyNAS Duo V2: SNMP: No Response

[m0urs]

I have enabled SNMP on my ReadyNAS with the following parameters:

Community: public
Hosts allowed access: 192.168.0.10

In SNMPD.CONF on ReadyNAS the following lines are present:

com2sec readonly 192.168.0.10 public
trapcommunity public

If I try to acces SNMP from 192.168.0.10 there is no response:

snmpwalk -v1 -c public 192.168.0.50
Timeout: No Response from 192.168.0.50

I tried also snmpwalk directly on the ReadyNAS but with the same result.

The SNMPD process is running

ps -ef | grep snmp root

root 4838 1 0 08:20 ? 00:00:00 /usr/sbin/snmpd -Lsd -Lf /dev/null -I -smux -p /var/run/snmpd.pid
root 4840 1 0 08:20 ? 00:00:00 /usr/sbin/snmptrapd -Lsd -p /var/run/snmptrapd.pid

I already did an OS reinstall on my device but with no success also.

Do you have any idea why SNMP is not responding?

Thanks, Michael

P.S. There is no local firewall issue on my Linux box. If I do a "snmpwalk" another device (e.g. a Netgear switch) an answer comes back ...

I found the root cause of the issue.

I needed to change the line

com2sec readonly 192.168.0.10 public

to

rocommunity public 192.168.0.10

and restart the SNMP task with "service snmp restart".

Afterwards I was able to successfully connect via SNMP to that device.

However: It seems that this type of NAS only supports a basic subset of SNMP IDs so that I am e.g. unable to read temperature, fan status, RAID status etc. so for me it does not make sense to monitor it 😞
