Auto create home dirs with Samba
20 Oct 2009
If you’re using Samba to provide network shares to your users, it might be usefull to autmatically create the their homedir when they access it the first time. This can be done by adding this line to the [homes] directive :
root preexec = /usr/local/sbin/mkhomedir.sh %U This is the mkhomedir.sh script itself :
#!/bin/bash if [ ! -e /storage_users/DOMAIN/$1 ]; then mkdir /storage_users/DOMAIN/$1 chown $1:"DOMAIN+Domain Admins" /storage_users/DOMAIN/$1 fi exit 0

Slow DNS resolving
22 Sep 2009
The other day one of our internal DNS needed to be shut down for maintenance. During that time people complained about slow responsiveness of the applications running on our RHEL machines. Because the DNS maintenance was the only change we made at that time we started looking in that direction.

64MB VPS
28 Jul 2009
I switched from Typo to Wordpress . I thought it would run a little faster on the 64MB VPS i use on my server. But WP uses MySQL as a backend and that doesn’t really help.
Apache is also quite a memory hog on systems with low memory, but with some Apache and MySQL tuning my blog isn’t going OOM anymore :).
I guess Apache and MySQL are a little to heavy on resources.

Typo with Phusion Passenger
22 Jul 2009
I’m running this blog now with the Phusion Passenger mod for Apache.
Normally this Apache directive should be enough to start your rails app.
VirtualHost *:80; servername mydomain.tld documentroot /var/www/html/typo/public /VirtualHost></pre> I had to change it to the following though to get it to work.
VirtualHost *:80; servername mydomain.tld PassengerEnabled on documentroot /var/www/html/typo/public /VirtualHost
