Lazy Umounting
I came across a mounted sdb1 partition, but the physical device didn’t exist. This was on a Red Hat EL 5 box.
No files in the mount point, obviously, no users logged in but me, and I wasn’t standing in the directory. Even lsof couldn’t show me anything about that directory, and I almost cried when fuser -km reported nothing killed.
Umount gave this error:
# umount /dev/sdb1 umount: /dev/sdb1: device is busy umount: /dev/sdb1: device is busy
In the man page, I found the -l option for umount. The Lazy unmount. It says this:
Detach the filesystem from the filesystem hierarchy now, and cleanup all references to the filesystem as soon as it is not busy anymore.
Sounds good to me, and it worked, too. Just watch out for data loss.

Add your www with mod_rewrite
about 1 month ago - No comments
It’s been said a million times, why do we need the www in the URL? The answer is simple: we want our sites to look professional. Here’s how to automatically prepend the www when some crazy hippie forgets it. In the LoadModules section of the config, make sure mod_rewrite is enabled. On Red Hat or
Plesk 9 and PCI compliance
about 4 months ago - No comments
The basics are easy, as one can attest with a Google search: Apache, Mail, etc. But, I’ve found that the Plesk CP for Plesk 9 doesn’t run on Apache, it runs on Lighttpd. To disable weak ciphers on a Plesk/Red Hat box, edit /etc/sw-cp-server/applications.d/plesk.conf and add this line: ssl.cipher-list = “TLSv1+HIGH !SSLv2 RC4+MEDIUM !aNULL !eNULL

So, Apple turned at off by default, cause who uses at, right? Well, I do. Here’s how you can too: $ sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.atrun.plist Once this is done, the at service is running. To make a handy-dandy alert system, try using at with the “open” command, like so: $ at 3:01 today [hit

Oh, my. What a weird couple weeks it’s been for my laptop… I started with Alpha5, in which suspend worked. Alpha 6 also supported suspend. Both with the open-source ati driver upon install. Beautiful! Thank you Ubuntu for having an awesome distro! Supposedly, the xorg-driver-fglrx package in the Ubuntu repos for the Hardy development version
Ubuntu 8.04 Hardy Heron Alpha and Beta testing
about 2 years ago - 3 comments
I love Ubuntu. It’s Linux that you can plug in and use quickly, without a whole lot of setup time. I even convinced my Uncle Phil and my Grandmother-in-law to use it, and they are die-hard Windows fans. Well, wow. My first impression once I got Hardy installed was that the new modern art deco
Plesk and root email
about 2 years ago - No comments
God help you if you have Plesk. But, if you do an you need to receive the system messages emailed to root, simply execute these commands as root on your RHEL server: # echo `hostname` >> /var/qmail/control/locals # /etc/init.d/qmail restart After this, log into the CP, and click Server->Edit. Change the Administrator Email to the
Adding Arguments to your Scripts

I like bash. It is simple and straight forward. In the words of Master Foo, “Is it he who writes the ten thousand lines, or he who, perceiving the emptiness of the task, gains merit by not coding?” One of the easiest things to do in a bash script that has more than one function
