Thomas,
Thanks for the input. I am going to try to beat my proxy statement into
submission. Below is some debug details for the record.
I would also be interested in testing the new AIX related snmp code when it
comes into play as well as try to figure out how AIX pulls that
information from the kernel.
The output of the command is
source$ snmpwalk -v1 -c public aix01:1610 1.3.6.1.2.1.4.20
Timeout: No Response from aix01:1610
source$
while the box shows that it is running and that the port is listening.
Occasionally the log for the AIX snmpd will get updated and a packet flagged
in it when you walk the host.
