Re: agents with net-snmp 5.4

Dave,
*It's not clear whether this is the Sun or the Net-SNMP agent. *
But the oid error happen when the sun master agent is not running ...


*Which agent is responsible for this MIB object ?
*it's the net-snmp agent code which implements this mib ...
I dont' know if that answer to this question...


I remove the proxy line of snmpd.conf file,
and I execute following command :

/usr/local/bin/snmpwalk -v 1 -c public localhost:7075 =

..1.3.6.1.4.1.2390.1.3.1

the end of answer is now correctly :
SNMPv2-SMI::enterprises.2390.1.3.1.15.2.1.0 =3D INTEGER: 0

I excute the following to use the master agent
/usr/local/bin/snmpwalk -v 1 -c public localhost .1.3.6.1.4.1.2390.1.3.1

the end of answer is not correctly :

I launch the agent with command :


I request it with:
/usr/local/bin/snmpgetnext -v 1 -c public localhost:7075 =

I don't see the forwarding to the master agent ...
