Hi,


I would like to configure snmpd to allow my client, IPMONITOR (from solarwinds) to be able to monitor CPU, DISK and memory on my ubunto box.

I am able to get the client to monitor the ports that are open along with ping, but i am not sure what my configuration should look like for the other monitors or even if it is possible to do with ipmonitor.
One of my config files is below.

my second question is whether it is safe to use snmp over the internet? obviously nothing is safe but an unplugged computer 2km's in the ground, but are other people doing this? and are their known exploits?

my third and final question is: what is a trap?

thanks!

system-group-read-community  public

system-group-write-community  public

read-community  public

write-community  public

trap  localhost.localdomain

trap-community  public

managers  localhost.localdomain

Depends which version of SNMP you are talking about.  SNMP v3 (the latest) has security enhancements over earlier SNMP versions.

If you are going to run SNMP, the very first thing you should do is to change the read and particularly the write community names from public to something a lot more secure.

You can think of SNMP traps as an alert.  Certain devices can be configured to send a trap based on some threshold being exceeded (eg: disk space, memory etc) and the SNMP server receives the traps and can perform some action based on the trap, eg: send an email or pager alert.
