I have 12.04 Desktop installed, how do I uninstall Network-Manager and set
/etc/network/interfaces as the default file to resolve my network connections?
If you manually manage your network card in
/etc/network/interfaces , network manger will not manage it , it will state "Not Managed"
Suppose your network card is eth0 :
To setup eth0 to static, enter:
open /etc/network/interfaces : auto eth0 iface eth0 inet static address 192.168.1.15 #------> Your Ip Address netmask 255.255.255.0 #------> Netmask gateway 192.168.1.254 #-------> Gateway broadcast 192.168.0.255 dns-nameservers 192.168.1.3 #-----> Dns server
To setup eth0 to dhcp, enter:
auto eth0 iface eth0 inet dhcp
The different keywords have the following meaning:
auto: the interface should be configured during boot time.
iface : interface
inet: interface uses TCP/IP networking.
Now restart service :
sudo service network-manager restart
