Remote Checks

[Hari Sekhon]

I know this is a tired subject but I'm now needing to expand beyond my 
nagios server and have have check run locally on machines in my 
infrastructure to make them tell me things like how much disk space is 
left etc...

I've looked at nsca but it appears to me that this requires a nagios 
instance to run on every machine. Please correct me if this is not the 
case. I guess you could wrap the plugin in another script which is then 
cronned to do the check and then send the results via nsca to the nagios 
server?

Nrpe take the more active approach but this seems weak from a security 
point of view to simply test the sender's ip address. Ip spoofing has 
been around for a while as I'm sure everybody here knows...

Then there's net-snmp. I've had a brief look but this is a little 
strange and I find it to be a bit complicated considering I'm not used 
to using snmp. Also, when I tried it out against stuff I know has snmp 
like printers, I couldn't get any info out of them unless I dropped to 
v1 even though after reading the docs I would think everything modern 
would use the more secure v3....


Could I get some advice/opinions about what I should do since I want to 
do this soon.

Thanks

Hari
