When fedora12 is started, enable the NIC and disable Firefox from working offline.

1. Enable the NIC when fedora12 is started:
1.1 open the system-> Manage-> network, and select
Double-click and change the settings:

1.2 open the terminal and enter the command, for example, [root @ localhost ~] # Gedit ~ /. Bashrc
After "IFUP eth0" is added to the end of the opened file, the complete file content is changed:
#. Bashrc

# User specific aliases and functions

Alias Rm = 'rm-I'
Alias CP = 'cp-I'
Alias mv = 'mv-I'

# Source Global definitions
If [-F/etc/bashrc]; then
./Etc/bashrc
Fi

IFUP eth0

At this point, the NIC is automatically activated when fedora is started.

2. When the system is started, Firefox is not set to offline.
Open Firefox, enter: About: config in the browser, and press enter to set toolkit. NetworkManager. Disable to true. The result is changed:

Done!

The above two methods can achieve our goal. In fact, there are many other implementation methods, which will not be introduced here!
