An attempt to track some of my thoughts on being a system administrator. Scanner characterization (free) to correct the colors in scanned pictures. That seems to do what I want, but it's not exactly the clearest documentation for someone who doesn't do digital image workflow for a living. But here's what I've figured out so far:. There's a zip of Windows executables. They seem to run on my Win7 laptop. First, we generate a "target". Targen -v -d 2 target. And now I'm waiting to pick up that picture.

An attempt to track some of my thoughts on being a system administrator. Small Business Server crash and recovery. I'm the "tech guy" for my parents' small business, and the new point of sale software for them runs on top of MSSQL on Windows Server. Step 1: Buy a system with Windows Server 2012 on it. (Check. $900 from Microcenter). Step 2: Take it home and set it up so that the POS people can install their software on it. Luckily, I have a spare 1TB hard drive in stock.

An attempt to track some of my thoughts on being a system administrator. Using Windows (Active Directory) passwords for Ubuntu. For various auditing reasons, we have centralized our passwords into our Active Directory environment. (Also because everybody gets a Windows account, and AD can easily enforce password changes, strong passwords, etc). And then go in and change your /etc/shadow entry to lock out the password you initially set for your username, by changing the encrypted string to *KRB*.

An attempt to track some of my thoughts on being a system administrator. OpenSSL to Java keystores. I've been creating SSL configurations for various groups in the company, and since I like the standard command line, I've been doing it via OpenSSL. However, some groups use Java-based SSL servers that need their .key and .cert in the Java Keystore format. So to get the whole instruction set together in one place,. Openssl genrsa -out servername.key 2048. Subscribe to: Posts (Atom). Sites I read daily.

An attempt to track some of my thoughts on being a system administrator. Common Event Format parsing. I've got some data in "Common Event Format" from our new Arcsight appliance, and I need to get it (or at least major parts of it) into a relational database. This should be fairly straightforward, except that the CEF format doesn't lend itself to be parsed easily. It's the 8th column that's giving me fits, though. In order to make CEF a useful standard, everything interesting about the event is stuff...

An attempt to track some of my thoughts on being a system administrator. Mostly to install this into my NVRAM, but also because there seems to be a shortage of quick instructions for this. Using VLC Media Player (Windows, version 1.1.2 in my case). Disc tab, No Menus, adjust title/chapter if needed. Add a destination file and optionally "Display Locally". I added a custom profile, MPEG-PS, Video and audio codec "Keep Original". Then rename the .ps to .mpeg or .mpg or whatever. Subscribe to: Posts (Atom).

An attempt to track some of my thoughts on being a system administrator. One of our many applications wouldn't start, with an obscure message that had nothing to do with the underlying problem (nsrexecd "Cannot start portmapper", to be specific and to make sure this is googleable for the next person).

Enterprise SA: Greenplum DCA and my roll-my-own ETL host
http://enterprise-sa.blogspot.com/2013/09/greenplum-dca-and-my-roll-my-own-etl.html
An attempt to track some of my thoughts on being a system administrator. Greenplum DCA and my roll-my-own ETL host. I'm trying to get my new Dell server with its 10gigE network cards to talk to the back-end switch of my greenplum DCA. Once there's a link at the SFP layer, however, the greenplum switches are not set up for ETL work out of the box. And of course, since these back-end switches are not connected to the "real" network, I have to ssh-tunnel to get to the Switch Admin web tools. And finally, ba...
