Hi, I'll give some more informations. Basically we would like to have servers on primary schools and remotely control/watch them from our main head computer. Also at off hours video surveillance application runs on them (called "motion"). So I guess I'd need somekind of secure connection with all of them (is VPN the solution?) to configure/maintain them and also to have some sort of heartbeat mechanism to detect failure at once - especially when used in security surveillance mode. All servers are basically local servers for local networks and also connected to Internet through router. Hope this helps a bit, thanks in advance, Robert. ----- Original Message ----- From: "Lyle Giese" To: "Robert Rozman" Sent: Sunday, June 27, 2004 4:56 PM Subject: Re: [suse-security] Recomendations for surveillance/configuration/heartbeat tool for remote servers

Off the top of my head, I can think of several products and/or custom perl scripts. Nagios is one such package that would ping/poll services and report outages. MRTG is one performance reporting package. But I can't tell if your network topology/connectivity will support either of these.

But to really get a flavor for your needs, I am thinking you need to post more information. Are these remote servers on one subnet behind one router or is each on it's own Internet connection behind their own or a shared router? Do you have any control over the router or is this in a colo site and you have no control over the router controls?

I am not an expert and you should repost to the list some more information if you want a realistic answer.

Hi,

I have a network of servers and I'd like to get some recomendations for selecting the right tools for this task: - I have a series of simple servers connected on the Internet - I'd like to remotely: - control all those servers, - watch their behaviour, - implement somekind of heartbeat function (servers send heartbeat packets in regular time intervals - if not received -> alarm), - statistics framework for performance analysis - if possible to have secure connections (possibly in software) also for other communication ports that other applications use ...

I found some tools like Argus, but as newbie I'm not sure if they satisfy my needs...

Any recomendation, idea, pointer to more info would be great,

thanks in advance,

Robert.
