Having worked on XenClient XT for the past year I’ve experienced the pain of debugging vendors TXT implementations first hand. TXT may be a nearly 6 year old technology but it’s just now coming into use and many vendors platforms have only received internal testing. We’ve found a number of ways for platforms to fail [...]
There’s lots of software out there that sets up a “sandbox” to protect your system from untrusted code. The examples that come to mind are Chrome and Adobe for the flash sandbox. The strength of these sandboxes are an interesting point of discussion. Strength is always related to the mechanism and if you’re running on [...]
It’s been a while since I’ve posted any new content but that’s not because I haven’t been doing anything worthy of mention. During the few breaks I’ve had from my day job I took the time to replace my QNAP 419p NAS with a custom system to host NFS shares. Here’s just a quick laundry [...]
I’ve been working on a set of scripts to backup the wordpress instances on my server. While structuring these scripts I realized that I hadn’t structured my WP installs consistently. I had played around with using table prefixes and hosting multiple WP instances in a single database but eventually I just broke them out into [...]
Working out of my “home office” these past two weeks I’ve found a few short comings in my setup. While on my first teleconference last week I spent an hour holding my cellphone to my head. Miserable. I never thought I’d miss a land line / speaker phone. Easy problem to solve though, just get [...]
Started with a new employer (Citrix) today. Naturally my first task of setting up a development system was more work than I wanted it to be. Turns out the EliteBook 2560p has Intel 83579LM network hardware and the Debian Squeeze e1000 driver predates it. Using ‘testing’ is always an option but not a very stable [...]
I’ve been working on a fix to a system script that passes around and manipulates IP addresses. With IPv6 becoming more prevalent this script must work with IPv6 addresses not just v4. While working on this and digging around the web I ran across some stuff that I think is worth sharing. The first thing [...]
Spent a few minutes searching for a howto for setting up ethernet interface bonding on a new file server I’m building today. Nothing special but I found a bunch that aren’t that great … I know, welcome to the internet right? But I did find one that’s awesome from tuxhelp.org. My final config went like [...]
I spent much longer than I’d like to admit moving my mail server today. The Debian exim4 package is very easy to configure and setting up TLS and authentication is a snap with the help of a very good Debian Administration article. Also I’ve had to tweak the address_file transport to support Sieve and the [...]
I’ve had a HP DL360 hosting my blog, MySQL, SMTP and IMAP servers for a while now. The server’s been great and I’ve always intended to add an online spare (a.k.a. hot spare) for a little piece of mind. I’ve finally got around to it and it turns out that the syntax for using the [...]
