Network configuration only works with DHCP

[Giorgos]

My network was working perfectly with breezy.

When I boot the dapper livecd, if I have dhcp disabled on my router then I can't connect to the net, I can't even get to my router's web interface. If I enable dhcp (by booting back into breezy) then it works and I can choose a static ip too.

[Scott James Remnant (Canonical) (canonical-scott)]

I'm sorry, I don't understand what you mean by this bug.

The LiveCD will default to DHCP on boot, but you can change to a static IP using the Networking control panel.

What behaviour did you expect instead?

[Giorgos (pinkisntwell)]

Yes, I can change to a static ip but then I won't have internet nevertheless. And since that even my router's web interface is unreachable, I had to boot into breezy to re-enable my router's dhcp server.

[Scott James Remnant (Canonical) (canonical-scott)]

Why don't you have internet access if you change to a static IP?

[Giorgos (pinkisntwell)]

That's the bug I'm submitting.

[Scott James Remnant (Canonical) (canonical-scott)]

Is the static IP in the block your router expects to answer on?
Is the broadcast address set correctly?

Can you ping the router?

[Giorgos (pinkisntwell)]

Right now I'm on breezy, so I'll check later on the ping part, although the fact that I couldn't reach the web interface from firefox (using ip address) must be an indication.

The other two questions I didn't understand, but I assume everything is set up properly since if I boot with dhcp enabled and change to static address it works.

[Scott James Remnant (Canonical) (canonical-scott)]

On breezy, please attach your /etc/network/interfaces file and the output of "ifconfig -a" run from a terminal.

Then do the same on dapper after making the change to a static IP address.

[Giorgos (pinkisntwell)]

Sorry for the delay.

On breezy:

/etc/network/interfaces:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# This is a list of hotpluggable network interfaces.
# They will be activated automatically by the hotplug subsystem.
mapping hotplug
 script grep
 map eth0

# The primary network interface
iface eth0 inet static
address 10.0.0.2
netmask 255.0.0.0
gateway 10.0.0.138

auto eth0

iface dsl-provider inet ppp

ifconfig -a output:

In dapper:

/etc/network/interfaces:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 10.0.0.2
netmask 255.0.0.0
gateway 10.0.0.138

ifconfig is unspupported on dapper

[Giorgos (pinkisntwell)]

Forgot to mention that on dapper I couldn't ping my router's ip.

All the above is with the dhcp server disabled on my router, then booting dapper's livecd and selecting static ip from system->administration->networking and setting all the parameters.

If I boot with the dhcp server enabled everything works perfect.

[Scott James Remnant (Canonical) (canonical-scott)]

ifconfig is NOT unsupported on dapper, please run "ifconfig -a" and give its output.

[Giorgos (pinkisntwell)]

I thought it was weird too, but are you sure? I tried several times and it wouldn't find it.

I even tried typing "if" and then tab to list it, but no luck.

I will check again.

[Scott James Remnant (Canonical) (canonical-scott)]

Try giving the full path "sudo /sbin/ifconfig -a"

[Giorgos (pinkisntwell)]

It worked using sudo and the full path... Weird. Here it is, output of ifconfig -a from dapper while the problem exists:

[Scott James Remnant (Canonical) (canonical-scott)]

Please purge the "zeroconf" package from your system.

[Giorgos (pinkisntwell)]

Is the problem fixed? Will it be working for dapper?

[Scott James Remnant (Canonical) (canonical-scott)]

Did you purge the zeroconf package from your system, and then reboot? Did it work then?

[Giorgos (pinkisntwell)]

I can't reboot, it's a livecd.
