I am using Ubuntu 11.10. In my dorm I have to change network configuration and then if it is successful, I have to enter a user name and password for wired internet connection. Anyway, I had many attempts but I couldn't achieve this, please look at my steps and tell me if there is something wrong. At the end there is an error, but I really don't have any idea about this error.
$ cat /etc/network/interfaces auto eth0 iface eth0 inet static address 172.030.014.038 netmask 255.255.255.252 network 192.168.2.0 broadcast 192.168.2.255 gateway 172.030.014.038 $ cat /etc/resolv.conf nameserver 010.050.001.001 nameserver 010.050.001.002 $ /etc/init.d/networking stop * Deconfiguring network interfaces...

Note: IP-address, netmask, gateway, Preferred DNS server and Alternate DNS server are given by the management of Dorm. It was very easy in windows but I couldn't achieve in Ubuntu. I also tried to edit from "Edit Connections" but the save button is not enabled and I cannot save it.
