I am having trouble getting a subagent to work.
I have attempted to follow the rules of support and first check alternative
sources.
I have been through the wiki and tutorials many times.
I hope this is not one of thoes cases where the answer is obvious and I have
complete overlooked it.
If that is the case then I am sorry.
Below is the process I used in detail.
0)
Tested the MIB with "snmptranslate".
It appeared to work fine.
I havent registered a number with IANA yet
so using 82 temporarily. Sorry "Auspex Systems, Inc".
1)
I inputted this line
env MIBS="+PS-TEST6-MIB" mib2c psTest6MIB
this was the response
OID: psTest6MIB
numeric translation 1.3.6.1.4.1.82
number of scalars within: 1
I choose Net-SNMP style code and to "tie interger values to integer scalars"
As expected is generated psTest6MIB.c and psTest6MIB.h
2)I then compile-subagent
net-snmp-config --compile-subagent psTest6MIB psTest6MIB.c
resulting in
"subagent program psTest6MIB created".
3)I start net-snmp
snmpd
Then I start the subagent
./psTest6MIB
All seems fine. No errors.
4)Testing
When using an SNMP manager connected to "localhost"
-Asking for the variable "1.3.6.1.2.1.1.1.0" does return the
"sysDescription". The SYSTEM tree does work.
-Asking for the variable "1.3.6.1.4.1.82.2" which belongs to the subagent,
returns null.
snmpget -v1 -c public localhost PS-TEST6-MIB::psTest6MIB
returns
"Eror In packet"
"Reason: (noSouchName) There is no such variable in this MIB"
"Failed object: PS-TEST6-MIB::psTest6MIB"
snmpget -v2c -c public localhost PS-TEST6-MIB::psTest6MIB
returns
"No Such Object available on this agent at this OID"
snmpgetnext -v1 -c public localhost PS-TEST6-MIB::versionTag
returns
"Unknown Object Idenfitier"
snmpwalk -v1 -c public localhost PS-TEST6-MIB:psTest6MIB
returns
"End Of MIB"
snmpwalk -v2c -c public localhost PS-TEST6-MIB::psTest6MIB
returns
"No more variables left in this MIB View(Is is past the end of the MIB
tree)"
Using
"snmpd -DpsTest6MIB" to start the agent
returns some errors

5)Confirgation
I added
rocommunity public 192.168.1.0/16
to the configuration. after that didn't worked I also added the following
lines
com2sec readonly default public
com2sec readwrite default private
That still didnt work
I also made sure that
master agentx
was uncommented in snmpd.conf
