Hi,
I had the network problem a couple day ago when I installed xubuntu (7.04) for the first time. I am hoping that I can get some help to get this resolved.
Here's how I repeated the installation procedure today;
1. install ubuntu-7.04-server (32 bit)
auto configured with DHCP.
accessible to internal network and internet with no problem.
Run the following commands in sequence,
"sudo ifconfig eth0 down"
"sudo ifconfig eth0 up"
Check internet accessibility, still alive.
"sudo /etc/init.d/networking stop"
"sudo /etc/init.d/networking start"
Check internet accessibility, still alive.
2. install xubuntu-7.04 on top of the server (32 bit)
make sure the CD drive is accessible
sudo apt-cdrom add (use alternative CD)
sudo aptitude update
sudo aptitude install xutuntu-desktop
selected NO CONFIGURATION when asked.
The install procedure downloaded 150MB data from internet.
After xubuntu-desktop was installed, I double checked that I still had access to internet. I was able to ping
www.yahoo.com; www.google.com.
I checked the "ifconfig -a" output. I may need to compare it with the output when I rebooted into xubuntu.
3. reboot into xubuntu
Checked the "ifconfig -a" output with that from the server. I did not see difference. The IP address was the same as when booted to server version. The NIC was up.
But I cannot ping internal computers and internet servers.
So I run "sudo /etc/init.d/networking stop"; the following was the output:
* Deconfiguring network interfaces ...
Postconf: fatal: open /etc/postfix/main.cf: No such file or directory
There is already a pid file /var/run/dhclient.eth0.pid with pid 4377
Killed old client process, removed PID file
...
Listening on LPF/eth0/...
Sending on LPF/eth0/...
Sending on Socket/fallback
DHCPRELEASE on eth0 to <IP> port 67
From this output, the DHCP address is the same as when booted into server.
Then I run "sudo /etc/init.d/networking start".
Now it does receive DHCP offers.
I have no idea where the problem is. Did I miss anything after installed the desktop?
