Hi Dave,
I am still not able to solve the issue.. I tried to omit the
if-mib in the make file and started seeing the errors like
./.libs/libnetsnmpmibs.so: undefined reference to `Interface_Scan_Init'
./.libs/libnetsnmpmibs.so: undefined reference to `Interface_Scan_Next'
./.libs/libnetsnmpmibs.so: undefined reference to `run_exec_command'
./.libs/libnetsnmpagent.so: undefined reference to `vacm_standard_views'
I searched the lists and found your suggestion to omit other mibs like "at".
"ip" but still not able to compile. What other mibs need to be excluded?
With that being said, when we exclude the if-MIB and provide our own
implementation, we need to provide support for these dependent mibs also?
Please help..
Regards,
Malathi

Hi Dave,
Further to my observations below, the line of the debug out put
says
trace: trace: ifTable_index_to_oid(): if-mib/ifTable/ifTable_interface.c, 432:
ifTable_index_to_oid(): if-mib/ifTable/ifTable_interface.c, 432:
verbose:ifTable:ifTable_index_to_oid: verbose:ifTable:ifTable_index_to_oid:

I would like to know, when I exclude the ifTable from the agent, why it has to
ask the agent code for the ifTable details? it should be asking my
subagent code right?
While excluding the ifTable, I was excluding only at run time using
"I-ifTable", do we need to "disable" the IF-MIB in Net SNMP make file as well??
I tried doing that but it has other dependencies on other MIBs namely IP-MIB
and it wont compile..
Am I in the right path?
Thanks and Regards,
Malathi

Hi Dave,
If I dont use -DALL, I do not see any debug out other than the seg
fault message.
This time I tried running only the standard agent and including all the
modules.. Everything works fine. udpTable shows up without any issues..
The moment I exclude the "ifTable" it starts giving the segfault. So it looks
like when I exclude the "ifTable" from the agent I should take care of
something more??
Do we need to handle any other MIB code when ifTable is implemented by
subagent? What are the other dependencies?
Thanks for all your efforts.
Regards,
Malathi

No - you turned on *ALL* debugging.
So any useful information promptly gets buried in a mass of output.
There's also not a lot of point in turning on the udpEndpointTable
debug output if you also disable this module altogether.
I suggested that you turned on debugging, *OR* disabled the
module - two mutually exclusive alternatives.
Please try the original suggestion first - enable the selected
debugging tokens *only*, and leave all modules active.

What happens if you don't run
your subagent?
Try *just* starting the standard Net-SNMP agent, and
run a GetNext on the udpEndpointTable.
Does the agent crash?
What does the debug output look like?
