Public Wave: Monitoring your Church’s internet usage internally

Trying out another public wave. This one is on Monitoring the internet access of the church network.

Monitoring your Church’s internet usage internally

Currently I am mirroring the outbound port of the last switch on our network and sending all of that data to a machine with two NICs. One simply gulps on the network firehose and the other allows me to RDP in.

I monitor the traffic with WireShark using the statistic options with IPv4 conversations, I/O, and HTTP requests.

There has got to be a better way to have ongoing monitoring on a tight budget.

Any questions or suggestions?

Trying a public Google Wave

I am trying out the Public Wave option using public@a.gwave.com with this post, but you will still need a Google Wave Account to join in.

This is a wave asking questions about Open-Mesh.

I am using the Wavr Plugin for Wordpress to embed the wave, but you can go directly to it here: The Open-Mesh Wave.

Tool: Wireless Keyboard & Touchpad

As a way to share tools I use regularly with others and find out tools that other IT people are using. So, I am going to start off with a tool I keep on hand and use at odd situations.

Wireless Keyboard & Touchpad

Logitech® Cordless MediaBoard Keyboard for PlayStation®3
or the
Logitech Cordless MediaBoard Pro Wireless Keyboard

The one pictured above is just the cordless mediaboard, but it is currently more expensive that the MediaBoard Pro and harder to find. It was originally bought to use with a media center PC attached to a big LCD TV, but plans changed and I put it into regular use at the church.

Some Points about the Hardware:

The USB dongle is the same size as a standard thumbdrive

There was no way to attach the dongle to the keyboard for storage so I superglued a magnet in a place underneath where the dongle could be held out of the way.

The keyboard feels flimsy and cheap, but it holds up pretty well.

They say the reach is 30 feet, however I plugged it into a computer and then walked out of the house and down the road probably 50 feet before the characters went goofy. This was through a standard exterior wall that had hardy board siding added onto it, and hardy board does a lot of damage to readio signals.

There is no software to install and windows recognizes it instantly. Macs will, of course, pop up the dialog to ask you to hit the key next to shift so it can be identified as a non-Mac keyboard but it works just fine.

The keyboard uses 2 AA batteries. I love this since it means that when I pull it out for use I can just take 2 AAs with me and not worry about the condition of the rechargeable integrated batteries that some remote keyboards use.

Uses:

Obviously it is good for presentations done by people who don’t like using an air mouse and do like a touchpad.

It also works well when assisting someone with a presentation. It is nice to be able to quickly plug into someone’s laptop so that if they do have problems during a presentation you are ready as a helper.

It works well in your lap when at a distance from the screen, but I would not use it as my daily desk keyboard. It isn’t comfortable enough for that position and duration.

We keep it as an emergency USB keyboard in my office. Since nobody wants it at their desk it isn’t going to go into circulation. I used it in the server room when a keyboard cord to the KVM had been knocked loose and the server came up without recognizing the KVM’s keyboard. It was easy to get into place without dealing with a cord, and the mouse was integrated.

And of course, it is good for pranks. Especially if you set up some good shortcut keys in advance.

Some Additional Stuff:

I need a keyboard and touchpad setup for a kiosk going into the bookstore. There isn’t enough room for a mouse on the ledge, and it seems too cumbersome, so I was looking at the Adesso Slim touch Desktop Keyboard. It is currently $37 at buy.com, but if you have any suggestions I would be glad to hear them.

Linux Command Line – SSH and Telnet

I just grabbed this from an old forum post of mine. It was originally written in 2002 or so, but I wanted to post it here as one of my reference items since this blog is where I come to find that stuff anyway.

This covers typical Linux commands used in web hosting.

Nobody Considers the Hole

It’s just Larry this and Larry that

Sure, most people completely overlook the necessary work in the background but background work is best when nobody thinks about it. Let’s just hope they have a boss who understands the task and knows a good hole when he sees it.

Update of the 10 Immutable Laws of Security

It’s been a while since I posted about the 10 Immutable Laws of Security, but with an update on it I need to have it marked here for future reference.

Windows Installer Service in Safemode

I’ve not tried this yet, but it is worth noting here.

Who’s that MAC?

Another item I looked for on the blog. The search page for finding the manufacturer of a network adapter based on its MAC address

Vendor/Ethernet/Bluetooth MAC Address Lookup and Search 

List of Available TCP and UDP Ports

Personal Note: Link to list of TCP and UDP ports.

I tend to search on the blog for this link, but I can never find it. That is because I never linked it here. So, here it is.

Wikipedia listing of TCP and UDP ports.

I usually expect to find it on the post about using a different Remote Desktop ( RDP ) port: Changing Remote Desktop Port.

That should be enough key words for my searches.
