in my dorm I have to change network configuration and then if it is successfull, I have to enter a user name and password for wired internet connection. Anyway, I had many attempts but I couldnt achieve, and please look at my steps and tell me if there is something wrong and at the end there is an error, but I really dont have any idea about this error. (I am a new ubuntu user, and network is far away of my interests)

1) /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

2) sudo gedit /etc/resolv.conf

nameserver 010.050.001.001

nameserver 010.050.001.002

3) /etc/init.d/networking stop

• Deconfiguring network interfaces... [ OK ]

4) /etc/init.d/networking restart

• Running /etc/init.d/networking restart is deprecated because it may not enable again >some interfaces
• Reconfiguring network interfaces... 172.030.014.038: Unknown host ifconfig: `--help' gives usage information. Failed to bring up eth0

Note: IP-address, netmask, gateway, Preferred DNS server and Alternate DNS server ara given by the management of Dorm. It wad very easy in windows but I couldnt achieve in Ubuntu. I also tried to edit from "edit connections" but the save button is gray and I cannot save it.

Thanks in advance. / Musti
