Re-Detect Network Interface Card in Ubuntu 13.04 and Centos 6.4

After making changes to the Network Interface Card (NIC), and when you run the command ifconfig, network adapters can't up. No visible interface ethernet (eth. ..), only the loopback interface (lo) is visible.

In ubuntu
If using the command "service networking restart", not seen the error. Use the command "ifup eth0", then you will get the error.

YFI Hotspot Manager on Fedora 18 / 19 and Centos 6.4

Logo YFI hotspot manager
Ok. Back to my experiment. I have spent many days to set up YFI Hotspot Manager, using Fedora 18 64bit, Fedora 19 64bit and Centos 6.4 64bit. If you are using 32 bit, it should be no problem. I didn’t use Ubuntu, because it’s often used. I do not want to be called just copy the post. Although this post reference to posts that already exist.
As usually, I assume a computer already installed, one of these operating systems, Fedora 18 / 19 or Centos 6.4, with a minimum packet. After configuration ethernet, and internet is ok, then continue to the next step.

YFI hotspot manager error
What do you think about the picture above ?  Yes. The login administrator yfi hotspot manager but there's no box username and password. Did you ever get an error like the picture above?  For me, the error like picture above, appear many times. I have collected many kinds of errors of installing YFI Hotspot Manager and how to fix it. This is all I got when I tried YFI Hotspot manager installation in Ubuntu 12:10 / 13:04, fedora 18/19 and centos 6.4. Do not be afraid, because of these errors. At the time of installation you will not get this much errors, (probably only get 1 or 2 errors only). You even probably will not get an error, if you follow the tutorial how to installing yfi hotspot manager correctly, and carefully. Especially following the tutorial from me ... hahaha ...

Remember this.
Sometimes when you have run the command to correct the error,  nothing can change. Still error / problem. This is because the permission of the selinux.  Make sure, you have disable selinux.
Edit /etc/selinux/config
SELINUX=disabled
Let's look at a list of errors and how to fix it.
