A permanent static route in Ubuntu Karmic Koala (9.10), Precise Pangolin (12.04) & Trusty Tahr (14.04)

Karmic Koala
To add a permanent static route to a Karmic Koala system with one NIC, you need to edit the
/etc/network/interfaces file. The following section needs to be replaced:

# The primary network interface
auto eth0
#iface eth0 inet dhcp

Modify as follows:
# The primary network interface
auto eth0
iface eth0 inet dhcp
up route add -net 10.8.0.0 netmask 255.255.255.0 gw 192.168.0.3
down route del -net 10.8.0.0 netmask 255.255.255.0 gw 192.168.0.3

File permissions on html server (recursive chmod) differentiating between files and directories

I recursively screwed up the file permissions in my html servers root directory. To fix it I needed to deploy some "advanced" chmod settings. Obviously I want to treat directories and files differently. I didn't come up with a better solution than the following:

chmod -R u=rw-x,g=rw-x,o=r-wx *
chmod -R a+X *
