If you have not been compiling as you went along, try and compile now.

make -f ifTable_Makefile
|
After running make, you should have an executable named ifTable.
You can run the ifTable agent as a regular SNMP agent, or as an AgentX
sub-agent. The default is to run as a sub-agent. While testing, the -f
(do not fork into background) and -L (log to stderr) options are
recommended.
|
|
AgentX Sub-agent:
|
ifTable -f -L
|
|
|
Standard SNMP Agent:
|
ifTable -M -f -L [udp[:port]]
|
Note that running the sub-agent application as a master agent will
runwithout any access control. All SNMPv1 and SNMPv2c requests will be
accepted, regardless of the community string.
For that reason, when testing I run as a regular user (not root), and
only bind to the localhost interface, like so:
|
|
$./ifTable -f -L -DifTable -M localhost:1161
2004-04-21 21:51:47 ifTable:init_ifTable: Registering ifTable as a mibs-for-dummies table.
2004-04-21 21:51:48 ifTable: using linux 2.2 kernel /proc/net/dev

A simple snmpwalk will quickly test the module:
|
|
$snmpwalk -v1 localhost:1161 ifTable

If you ran the agent with debugging, you should see something like this:
|
|
$./ifTable -f -L -DifTable -M localhost:1161
2004-04-21 21:51:47 ifTable:init_ifTable: Registering ifTable as a mibs-for-dummies table.
