Hi,
I created a MIB, and tried to allocate values to new OID
You find attached my MIB file, data_set.c and data_set.h.
After that I copied the files data_set.c and data_set.h in the source
directory of Net-SNMP: net-snmp-5.1.1/agent/mibgroup /
I continued as follows :
# ./configure --with-mib-modules="data_set host"
# make
# sudo make install
after that I started the SNMP agent :
#/etc/init.d/snmpd start
Then i tried to see if the daemon knows about *new enterprise*, for this
reason i did :
#snmpwalk -v 2c -c private 127.0.0.1 .1.3.6.1.4.1.4890.1.1
which outputs are : SNMPv2-SMI::enterprises.4890.1.1 = No Such Object
available on this agent at this OID
So I guess that snmpd is telling me he can't find anything under this tree,
because nothing has been set yet.
So I tried to set this test variable with snmpset on the shell command :
#snmpset -v 2c -c private 127.0.0.1 .1.3.6.1.4.1.4890.1.1.2.\"mtdcsun0\" i
89
which outputs are :
Error in packet.
Reason: notWritable (That object does not support modification)
Failed object:
SNMPv2-SMI::enterprises.4890.1.23.2.8.109.116.100.99.115.117.110.48
and as root, but with no success
But when I do a snmptranslate, I can see that the MIB is parsed correctly
Would you help me to solve my problem ?
Best regards,
