Ever heard about ARP spoofing or man in the middle attacks? If not then this may not be for you, but if on the other hand “Yes” then here is a tool for you..
Our pal Irongeek has released this nifty small util “DecaffeinatID:” that will sit in your tray until it detects something nasty going on (like eg. attempted ARP spoofing of your default gateway) and then raise hell and bells to warn you.
Basically what it does it to monitor the MAC address of your default gateway, if this for some reason changes (which it never should) you will be warned and can take precautions.
Besides this ARP ‘shield’ the util offers a few other nifty security tricks, anyway check it out at;

I just heard one of my favorite podcasts this morning, in this they talked about Carbonite and how they have actually changed their crypto policy lately. Before you had to rely on their crypto keys, which meant that although all your data was encrypted both during transport and storage it could basically be decrypted by Carbonite employees (yes yes, court order and all I know, but still I like my data to be 10000% private), however now you can set your own AES key (256bit as I recall) and thus data is 100% private..
This does make Carbonite an interesting player once again… I may just have to give them a spin to see how it works.
Yet another player came to my attention, I have not heard about this before nor do I know much more than stated on their website; www.backblaze.com
So to summarize;
Idrive (I use this myself, but am considering Carbonite to get more space)
Pros;Cheap (around 55$ a year), versioning of files, good gui with tons of tweaking, scheduled backup
Cons;“only” 150gb storage, gui could do with an update lots of options but not pretty

Carbonite (I have not tested this myself and thus know only little about it)
Pros; Cheap (around 55$ a year), UNLIMITED storage
Cons;no versioning of files (only the latest version is backed up)

Just learned about it, don’t know much about it.

Just learned about it, don’t know much about it. (I was warned it should be very costly).

If you are a sysadmin, then you know the problem with services of vital equipment that keep failing every now and again!? So what do you do? Wait for the users to start calling, buy an expensive monitoring solution or just do some simple scripting?
Well I’ll just give you a quick brief on how to setup the cheap (free) scripted solution that will help keep your users happy and the services running.
I was inspired by an article at; http://www.intelliadmin.com/index.php/2010/01/get-notified-when-a-service-fails/
which was quite cool except he rely on a third party utility for mailing AND he does not relaunch the service.. I have chosen to create a VBS script that will E-Mail AND re-launch the failed service in one sweep.
Ok here goes.
- First of all log on to the server/workstation in question (the machine where the service is running).
- Download my vbs script here (you may need to rightclick and choose save as)
- Modify this part of the script in notepad with your details (smtp server, email address etc)
- Save the file to somewhere on the C drive (I usually use “c:\windows\schedule”)
- Now enter “Computer management” (right click on My Computer and choose “Manage”)
- Select the service you wish to modify/monitor and double click it
- Modify the service as follows (you will need to modify this if you use another location for the script)
You will note that I set the script to run at the “second fail” not the first, you can set it to run at the “first fail” if you like – to avoid being bombarded I just choose first to be informed the second time a service fail. - The service name (described in the script) is NOT the displayname, it is the REAL name of the service, you can find this here;
And viola you are done, from now on you will get an E-Mail every time a service has failed twice (or the first time if you prefer).. It’s all very basic but neat.
