Static ip creation problems

[hiddeninfluence]

I have been trying to assign my computer static IP address, as I want to perform network traffic monitoring.

I have used the the standard "sudo nano /etc/network/interfaces"

assigned my

auto eth0
iface eth0 inet static
Address
Netmask
Broadcast
Dns-nameserver

Reset the connection, didnt connect. What am I doing wrong?

What version? what flavor? how did you reset the connection?

Current Desktop versions of Ubuntu use network-manager, you should really use the nm-applet GUI to edit the connection and set the static IP there (it's in the IPv4 settings - change the drop down from DHCP to Manual and enter the IP details)

Anything you specify in /etc/network/interfaces won't take effect until you restart the older networking service (or reboot) - it's OK to do that if you really want to, however if network-manager is still installed / running it can make things unnecessarily complicated imho

You should be able to assign a static address via Network Manager.

Oops - out-typed!

I am running Ubuntu 12.10 desktop, I reset the connection using "Sudo ifconfig eth0 down, Sudo ifconfig eth0 up" I dont know about network manager, from what you have described I can do that in network settings. Is this what you are on about?

The one I use is in the top bar towards the right side. It is an up/down arrow icon in 12.04.
Network Connections looks like the same tool...

That's it brilliant, should it update the /etc/network/interfaces ​file after I have done this?

[steeldriver]

you will need to go back and manually revert any changes you made to /etc/network/interfaces (i.e. so it contains only the lo / loopback definition)

thank you very much

Network Manager keeps it's own settings (I don't remember where). It shouldn't modify /etc/network/interfaces
