Are you running this as yourself, or as root?
Port 162 is a "privileged port",
so you need root access to listen on it.

This is probably easiest if you use the 5.1 (or 5.1.1) version of
the trap handler. We've re-structured the internals to make this
sort of this much more straightforward.

You'll still need to tweak the code to include your function,
and tell the trap handler (when) to call it. This can't be
done from the config file. But the basic operation should
be much cleaner.

It's not a command. It's a config directive within the 'snmptrapd.conf'=

file. You specify the command that you want to be run.
For example:

traphandle linkUp /usr/local/bin/handle_links
traphandle linkUp /usr/local/bin/handle_links
traphandle ROYAL-MAIL::fragile /usr/local/bin/handle_with_care
traphandle default /usr/local/bin/handle_the_rest

You'd need to write the commands 'handle_links', 'handle_with_care'
and 'handle_the_rest' (which could be shell scripts, tcl scripts,
C programs or whatever you like)
The 'snmptrapd' command would take care of invoking them appropriately

Hi,=20

Thanks for all ur replies. I'm able to do it as root. I've one more
question. I would like to capture trap messages and pass it to a
procedure (function) which parses the trap message. How to do this? I
tried to use "traphandle" command. But I don't find such command at all.
I found one, but the file type is commands text. So i'm wondering where
can I find traphandle command in net-snmp.=20

Is anybody using net-snmp with tcl? If so can you plese let me know how
r u handling trap messages.=20

bash-2.03$ pwd
/automation/usr/local/share/snmp/snmpconf-data/snmptrapd-data
bash-2.03$ type traphandle
traphandle is hashed (./traphandle)
bash-2.03$ ls
formatting snmpconf-config traphandle
bash-2.03$ type traphandle
traphandle is hashed (./traphandle)
bash-2.03$ file traphandle
traphandle: commands text

Thanks
Kousalya
