Gustavo Duarte’s Linux Internals Series

I have been reading Gustavo Duarte’s blog for last few days. The blog contains very good and neatly written contents on Linux internals. He has explained the things in the simplest manner using code and, especial mention to, excellent diagrams.

I would definitely recommend you to read the blog series, if you are interested in Linux internals.

Network disconnect in fedora 9 x86_64

Using a x86_64 DVD version of Fedora 9, I have installed the system and noticed an issue: the network is not active. The issue seems to be with NetworkManager service.
To resovle the issue, follow these steps –
#vim /etc/sysconfig/network-scripts/ifcfg-eth0

and add line or change it, if already there-
NM_CONTROLLED=yes

If you like to use GUI than execute this command as root
#system-config-network
it will open a Network configuration window. Edit eth0 configuration. Select the checkbox “Controlled by NetworkManager”.

Once you have made the changes by either way reboot the system. It should enable the network.
