I believe the agent is running as root.
It is started automatically on system boot by chkconfig.
When I make config changes in snmpd.local.conf I "service snmpd restart" as
root.
#service snmpd status
snmpd (pid 1330) is running...
#ps -U root -u root u | grep 1330
root 1330 0.0 0.8 83308 8204 ? S<l 16:12 0:00
/usr/sbin/snmpd -Lsd -p /var/run/snmpd.pid -a
I run the snmpget/set/walk commands as a non-privileged user.
I also tried running snmpwalk as root and still get this error:
#snmpwalk .1.3.6.1.4.1.15966.1
SNMPv2-SMI::enterprises.15966.1 = No Such Instance currently exists at this
OID

That file is present with mode 644, owner:group is root:root and has a time

Damn! It's like when you take your car to the mechanic and the funny noise
doesn't happen.

I don't think so.

I do not see any messages in /var/log/snmpd.log. it has a timestamp of March
11, and is zero bytes in length.
