Hi, Joan,
 
I just tried it and it didn't work... what's the version of net-snmp you
used?
 
On Linux tried: 
    kill -1 <pid>
    kill -SIGHUP <pid>
    kill -s SIGHUP <pid>
    kill -s 1 <pid>
    kill -hup <pid>
 
Thanks,
Feng

kill -hup pid, where pid = the snmpd process id.
 
worked when I tried it.

Hi,
 
This is Feng. I am poking net-snmp software 5.4 on x86 Linux (ubuntu
7.4) and trying to see how it can reloads the new configuration (such as
the updated community string). Googled some articles, I thought SIGHUP
signal needs to be sent to snmpd process. I also took a look at the code
and it seems that on Linux it installs the signal handler for SIGHUP to
set a reconfig flag. But for me, snmpd always simply died after I "kill
-s SIGHUP <snmpd_pid>".
 
Snmpd was started with the following command line options:
"
-u 0 -Ls5 -Lf /dev/null -p <PID_FILE_FULL_PATH> -c
<SNMP_CONFIG_FILE_FULL_PATH> -M <MIB_DIRS>"
"
 
Thanks for any feedback here.
Feng
