It’s probably a naming or DNS issue… As a temp test, create a hosts file with all the systems in it. If it works fine then try and isolate that DNS issue…

openssl and Signatures
A checksum can be used to determine if a file has been tampered with at a later date. To run a checksum use the following command: openssl dgst -HASHTYPE path_to_file HASHTYPE would then be md2, md4, md5, mdc2, rmd160, sha or sha1. Let’s go ahead and do a checksum of our smb.conf file: openssl dgst -md5 /var/db/smb.conf You should then see output similar to the following: MD5(/var/db/smb.conf)= e4b58a63c6682b298aeca3ad40734c1e MD5(/var/db/smb.conf)= e4b58a63c6682b298aeca3ad40734c1e

The Hidden Google
I originally posted this at http://www.318.com/TechJournal Google is a key tool for just about every Web user these days, and it remains the most popular web search engine in use today. But many of Google’s coolest features often get overlooked. Here are some of Three18’s favorite Google tools: Google Toolbar (toolbar.google.com): Windows users can save themselves the step of navigating to Google’s homepage by adding the Google Toolbar to their Internet Explorer browser. In addition to fast access to web searches, you also get a history of your most recent searches, bars indicating relevance of your searches, and links to other Google resources. But its most welcome bonus is its…

Packet 8
I originally posted this at http://www.318.com/TechJournal Voice over Internet Protocol (VoIP) is the technology used to transmit voice conversations over data (computer) networks using the Internet. The data network can be T-1, DSL, Cable Modems or any other high-speed Internet (broadband) connection. In the past few years, Vonage took the country by storm, offering low cost unlimited long distance using VoIP. For most residential users, Vonage is perfect. Vonage is easy to setup and use and has all of the features a standard phone would have for a fraction of the cost for most people. ViaTalk, Sun Rocket, ITP, Lingo, SpeakEasy and TalkTimes.net are all competitors to Vonage, but while…

The location and contact information are also reset. The settings for drives, drive cache, prefetch and other array based information will not be reset. If you only want to reset the password of an Xserve RAID you…

Xsan: Backing up the Configuration
cvgather is a tool that can be used to “gather” up all the relevant information (cfg files, etc) on your Xsan and back them up to a specified location. Any time you will be fussing around with the SAN, etc. then you should run this first. Additionally the copy of the config files can provide you with an escape clause with regard to certain issues that could cause the volume to get destroyed so I would have a copy of all your info on a location other than the SAN at all times anyway. This isn’t to say that cvgather will actually back the SAN itself up. It very specifically…
