Simple LDAP authentication domain server and client
Here, I’ll admit it. One of the things I’ve always been a little scared of, in terms of Linux server administration, is LDAP. It’s obviously incredibly useful in many ways, not the least of which, it’s the most current and secure way of centralizing user, group and system configuration information, even across the web. And [...]
Set up NIS client and server systems with autofs home
NIS is a bit of an old-school solution on UNIX systems for sharing user information, including logins, across systems. This allows administrators to centralize all user account information, as well as home directories, across any number of physical machines. There are some security implications (like having to disable iptables on the server, see below), and [...]
read and convert 3GP video using FFmpeg
Something I found out today when I decided to make a quick edit to a video taken on my cellphone: Newer GSM cell phones and devices (such as my now-dated Android G1) now tend to save video in 3GP format. This shiny new multimedia format may have many advantages, but it is not widely supported [...]
saving image dimensions with file_column
A minor UI detail in development required that we include the width and height of certain images in the HTML and XML views. Since we were using the file_column plugin, which doesn’t normally save any image information besides the file name, this turned out to require some hacking.
exporting NFS shares from Linux to OS X with iptables
This seems to be a very popular subject to write about for those of us with the fix-it-and-forget-it mentality. But everything I dug up either contained outdated information or set up too unnecessary hoops (like this Redhat KB article for instance). So as my attempt to better the world today (and make a record for [...]
ASUS Eee 1008HA – I fixed that for you
The ASUS Eee 1008HA is the latest in the popular line of ‘netbooks’ that are reportedly taking over the world, or at least the consumer electronics portion thereof. We picked one up from Amazon for about $419 as a way to keep in touch during summer travels (because, really, what good is a vacation if [...]
How to setup a SSL certificate for use by courier-imap and qmail in Plesk
lifted from here This howto will show you how to setup an SSL certificate on a Plesk server so that it will be used when people connect through secure pop, smtp and imap. To do the following, you need a certificate. It can be self signed or CA signed. Using a self-signed cert will of [...]
jail time: chroot’ed sftp with rssh
Installing rssh to allow scp/sftp sessions only for user accounts is a breeze. Getting them into a chroot jail took a bit more reseach, but in the end turned out to be pretty easy. This is on CentOS 4.6, but this technique should work almost identically for any Linux system thanks to the l2chroot script.
a really easy migration to github from subversion
Yep, I’m trying to git on the bandwagon too. Last fall I dropped a small set of plugin files into github as a test, which was easy enough. But never had the time to figure out how to get all the other plugins, libraries and frameworks we use in there without moving everything over, including [...]
TiVo file and app sharing with a linux-based home network
Set this up late last year, and just documenting now in case I forget, or if any of my legions of readers are curious. Galleon is a open-source java client/server app that uses Tivo’s Home Media Engine system to allow all sorts of file and application sharing between a Tivo and other networked entities. It [...]
