I’m trying to find some good open source network monitoring software.

Continuation here https://michaelellerbeck.com/2008/08/04/network-monitoring-zenoss-spiceworks-nagios-hyperic/

First I downloaded the vm version of Zenoss, it fired up pretty easily and I was in to the web interface. I was looking around for some way to do an autodiscovery of the network but couldn’t finid it quickly so I guess I will have to read the manual 🙂

First strangeness I encountered, following the manual I try to change the password for ‘Zope’ by entering zenpass. But it doesn’t work. I don’t like that. The next thing I notice is an error, something about a problem pinging localhost?? thats strange.

Ok, the interface is pretty confusing. This is what it says

From the left navigation menu select networks. The Networks Overview page appears.
2.  Click the checkbox next to the network you want to add all of the devices from. You can also use Subnetworks table menu to add a new network to the list.
3.  Once you have selected the network, open the Subnetworks table menu and select Discover Devices.
4.  The Discover Device page will appear showing you the status of all the device collections going on.

So what the heck is the table menu you might ask?? Well it looks exactly like a sort column arrow.

Would you guess to select that arrow?

Hmm ok, so It looked like it started doing something… although now I’m getting a bunch of errors?

I deleted and re added the network, and now it was able to find a few machines… but the console keeps on saying Neighbour table overflow???

Well, all and all, it looks cool but still has a few issues to work out.

Because of Open Source you have no excuse! Anyone who needs it should have a VPN connection

Imagine that Avian flu comes a chirping, killer bees come a stinging, and some crucial bridges fall over so that none of your workers can get in to the office. What’s your backup plan? Where’s your disaster recovery.

This is a case for duh dah dah da (can you hear the trumpets) Captain Open Source with one of his trusty sidekicks OpenVPN.

Then again if you were a small business and just wanted your workers to have remote access then OpenVPN is also a good solution for that.

But back to the disaster… let’s say your CEO needs access to his super secret Intranet strategic management portal. What are you going to do? How are going to provide access? Let’s say a hundred of your stranded employees need access.

Get yourself any old box (well if you had a lot of users you would probably want a more decent box) install OpenVPN, create your certificates, encrypt and send the certificates and setup file to your employees. Have them install the OpenVPN client and drop the setup file into the config folder. Done. Remote Access. Free and Good. What can be better?

I’ve been working on the ‘mellerbeck guide to OpenVPN’ it will show you how easy it is!
