How to setup my ubuntu for static ip address

[polardude1983]

Ok so I am trying to access my ubuntu 10.4 pc from my iphone. I have mocha vnc lite installed on my iphone and I got this in my startup applications

x11vnc -forever -usepw -httpdir /usr/share/vnc-java/ -httpport 5800

It only got connected like once, but haven't been able to connect to my pc again. I'm guessing because i need to have a static ip address, My computer is just connected via ethernet to the modem.

This is in my /etc/network/interfaces file

auto lo
iface lo inet loopback

christoph@christoph-desktop:~$ ifconfig
eth0      Link encap:Ethernet  HWaddr 00:1a:92:be:fd:0c  
          inet addr:192.168.1.100  Bcast:192.168.1.255  Mask:255.255.255.0

A few options:
You can configure the DHCP server (router?) to configure a "static lease" - essentially a static address.

Network Manager will let you manually configure an address - just be sure the address is in the same subnet, but outside the DHCP server address range.

You can configure a manual address in /etc/network/interfaces. As Network Manager evolves, it gets more aggressive and can conflict with /etc/network/interfaces. There are ways to fix it, though...

The "gui" way.

Click System > Preferences > Network Connections


Go to Wired/Wireless etc "auto eth0 / auto wlan0" click edit > IPv4 Settings > method > manual: and fill in a ip adres
f.e 192.168.1.10 > netmask=255.255.255.0
Gateway -your gateway- / routeradress
f.e; 192.168.1.1

Dns servers will be found in the router settings.
use a , to divide the primary and secondary dns

Yeah that went over my head

[polardude1983]

My computer has been without internet for 2 hours. i can't take it!

[polardude1983]

I've got like 20 tabs open on trying to configure a static ip and doing what each one says change this or change that and this and that. and still no internet.

And when i switch back to DHCP i dont get internet again. why? argghg

While configuring NM You should hit enter after giving IP mask and gateway.Then give DNS and apply.

[polardude1983]

I entered random numbers in the ip address. like oh 192.168.1.197 saved it restarted my pc and no internet
