Save Websites to Mirror a Browsable Version Using wget or webhttrack

using wget

http://www.boutell.com/newfaq/creating/mirroring.html
http://ubuntuforums.org/showthread.php?t=654722&page=2

wget -m -k -K -E http://example.com/

If this command seems to run forever, there may be parts of the site that generate an infinite series of different URLs. You can combat this in many ways, the simplest being to use the -l option to specify how many links “away” from the home page wget should travel.

Note: some web servers may be set up to “punish” users who download too much, too fast. You can avoid this problem by using the -w option to specify a delay, in seconds, between page downloads.

Renaming Network Interfaces (When Changing Network Cards)

When I inserted a new network card into my Linux computer, the new network interface was named with an incremented number at the end. I didn’t want that as my network setup (firewall rules etc.) were set up for the former name. So I had to change the configuration to rename the new interface.

I found the found the configuration file where the names of the network devices are saved using this command:

cd /etc/
ls `sudo find . -type f -print  |xargs grep -l -s "eth2"`

So I edited the file:
