Zenoss - locations

I've tried setting up and running Zenoss a couple times and the newest version 3.0.1 is pretty nice. Like previous versions it's easy to download, install and get up and running. Some of the options are in new places so it took me a little time to figure out where they were, but again the same ease of use was there.

One thing that was not so straight forward was how to get devices to show up in their locations. This isn't, as I thought, information that is pulled out of SNMP, but rather information that you define. As it turns out though, it is as simple as clicking just to the left of the device name and dragging it into the location you have defined. Once you have done that you will be able to manage your device both by device type that you defined at discovery as well as by location that you can customize as you like.

Cisco: connecting the old with the new

I spend as much time working with older network gear as I do the new stuff. On a recent project I found myself needing to connect an old Cisco 2950G with a new Cisco 3750E and was running into issues getting the duplex settings configured correctly.

To keep a long story short I headed out with my crossover cable as I often do, connected the two switches together and could not get the two switches to run the same duplex without CRC errors.

Turns out a standard patch cable and the assistance of auto mdix on the 3750e is all you need.

On the 2950G I did the following
int fa0/1
speed auto
duplex auto

On the 3750E I did the following
int gig 1/0/1
speed auto
duplex auto
mdix auto

Suddenly I have two error free interfaces running 100/Full.

If you have run into this issue, you might want to give this a shot, it has worked for me every time I have tried it since stumbling onto this.

Need old versions of Java?

If you're like me you have run into apps from time to time that will only work with a specific version of java. If you're like me and you are in the habit of cleaning up old files, you probably no longer have those previous versions available. I'll save you some digging, not that it is overly hard to come by in the first place, below is a link the the java archives page. There you should be able to find the java version you need to get up and running.
