NoAccess error in snmpset

Question

Hi,

I have a MIB object with read-write permission. MIB section looks like this:

EnableHalt OBJECT-TYPE SYNTAX Integer32 MAX-ACCESS read-write STATUS current DESCRIPTION "implemented in NetSnmpcodsMr.c file." DEFVAL { 0 } ::= { Scalars 4 }

When I do a set on this object I get: sudo snmpset -v 2c -c public localhost 1.3.6.1.4.1.8072.2.2.4.0 i 1 Error in packet. Reason: noAccess Failed object: NET-SNMP-MIB::netSnmp.2.2.4.0

When I do a get:

snmpget -v 2c -c public localhost 1.3.6.1.4.1.8072.2.2.4.0 NET-SNMP-MIB::netSnmp.2.2.4.0 = INTEGER: 1

All is fine!

In snmpd.conf I added the line:

rwcommunity public localhost

Still noAccess issue. I'm using net snmp 5.4.2.1 on Ubuntu

What am I doing wrong? Please advice Thanks Gil

Gil,

If that object is read-only, then you probably will receive notWritable instead of noAccess.

So I think it is still a Net-SNMP configuration issue and you can post to Net-SNMP mail list or check out the archive,

It's nine months since you asked this but in case it's helpful...

Is your community string correct? You specified it as "public", which is the default read-only community string. Perhaps it should be "private" instead, which is the default read-write community string.
