The issue is VERY similar to this problem:

showthread.php?t=491092

I'm at home running a cable modem --> linksys wrt54g --> Two home computers and two Ubuntu Servers (sunfire x2200's)

Router is set to DHCP. Both macintosh machines are able to pull an IP, one is wireless the other is wired.

I added the two servers the other day (Ubuntu server latest stable release). I have the cable installed in eth1 (I also tried this in eth0). The /etc/network/interfaces file is set as follows:
---
#the rimary network interface
auto eth1
#iface the1 inet static
# address 192.168.1.111
# netmask 255.255.255.0
# network 192.168.1.0
# broadcast 192.168.1.255
# gateway 192.168.1.1
iface eth1 inet dhcp
---

after changing it from static (I commented all the lines) I ran sudo /etc/init.d/networking restart and I get the following:


There is already a pid file /var/run/dhclient.eth1.pid with pid 4897
killed old client processes, removed old pid file
<snip>
dhcpdiscover on eth1 to 255.255.255.255 port 67 interval 3
dhcpdiscover on eth1 to 255.255.255.255 port 67 interval 4
dhcpdiscover on eth1 to 255.255.255.255 port 67 interval 7
dhcpdiscover on eth1 to 255.255.255.255 port 67 interval 12
dhcpdiscover on eth1 to 255.255.255.255 port 67 interval 5
No DHCPOFFERS received
no working leases in persistent database - sleeping


Now I run ifconfig eth1 and this is returned:

eth1 link encap:ethernet hwaddr 00:16:36:68:46:0e

As you can see it's not pulling an IP address!
Any ideas what is going on?

I've tried both machines, multiple ports on each. I tried setting it up as static. I reset the servers, I reset the router.

I'm at a loss.

TIA,

I have a similar problem with Ubuntu 7.04 (Feisty). The differences being that I'm trying to connect via wireless. I have to restart networking 2-5 times before I get an IP Address. I'm also running a WRT54G (w/ DD-WRT Firmware).

I wonder if there is a bug in the DHCP client that got pushed out with Feisty?

Hopefully someone can answer. Have you tried the Ubuntu forums?

Thanks,

But you were able to get it to pull an IP? I would love that.

I went to ubuntu forums but it's down - say's try back later.

So, just keep doing a /etc/init.d/networking restart ?

That's what I did, sometimes it worked sometimes it didn't. It is unfortunately halting me from using linux on my laptop because I don't want to spend 20 minutes everytime a boot up to get an IP Address... I hope it's an easy fix.

I'll report back as to the result.... I'm still not getting anywhere.
