The other day I posted a couple of questions re: FreeBSD and the port of
the CMU CNMP package to it. I now have most of the answers to those
questions to one degree or another.
In order to have the agent work correctly in a FreeBSD which does not have
the ether pseudo-device confgured into the kernel you need to make the
following small change to snmp_vars.c in the agent code:
2089a2090,2095
> if (nl[N_ARPTAB_SIZE].n_type == N_UNDF) {
> arptab_size = 0;
> arptab_current = 0;
> return;
> }
This just checks to see if the ARP table really is in the kernel and sets
its size to 0 if it is not found.
Also, in general, I think that the snmpwalk program should not be used
with the -v 1 flag, because it does *not* generate true V1 protocol
behaviour... i.e. snmpwalk still issues get-bulk type requests in this case
even though get-bulk is part of the V2 protocol.
