Wake On LAN / Networking Help

[bradhawk]

So, I set up my server using " The Perfect Server - Ubuntu Gusty Gibbon 7.10 ". When setting up I had a wireless PCI adapter installed as eth1.

But to change from the unreliability of the wireless, I removed the wireless PCI adapter card. I connected my ethernet card to the router using a crossover cable. I attempted to run

apt-get update

which attempts to connect to the internet but fails. It also failed when the wireless PCI adapter was installed.

ifconfig output looks like this:

brad@cougforlife:~$ ifconfig

Anybody having a solution to get the internet working?

My next question is how do I set up my server to automatically start if it loses power because of a power outage. The only way I've found to do this is using WAKE ON LAN. I followed this page:

http://n01getsout.com/blog/2006/11/1...inksys-wrt54g/

I attempted to wake my computer up using the web based utility. It didn't work. I do have my router forwarding port 9 via UDP to 192.168.1.112 which should work.

Anyone know a better solution to this problem or how to set up WOL?

Thanks!

Hi,

please try the following:

Disable the network in all runlevels and enable the Network Manager & Network Manager Dispatcher. After that reboot your system - you should now be able to use your WLAN-card as described here at step 11.

If you want to use WOL you should have a look into your BIOS-settings - you have to enable it there.

Best regards,

Olli

what do you mean by

Disable the network in all runlevels

are you referring to running this command:

/etc/init.d/networking stop

??

enable the Network Manager & Network Manager Dispatcher

How do I do this?

Finally, how do I look in my BIOS / enable it in my BIOS?

Thanks for all your help.

Forget what I mentioned in my first reply - I didn't read "server"
I think I found your problem.

Please change

network 192.168.0.0
broadcast 192.168.0.255

to

network 192.168.1.0
broadcast 192.168.1.255

in your network configuration. After that you should be able to connect to the internet.

Best regards,

Olli

That didn't fix it.

In my researching yesterday I stumbled upon people talking about editing the /etc/resolv.conf file.

I have listed my nameservers in the /etc/network/interfaces but I don't think it actually reads it from there so I also put it in my /etc/resolv.conf file. It has the domain listed as mshome.net which I don't believe is correct. How would I find out what to change it to?

My /etc/resolv.conf file looks like this

search mshome.net
nameserver 24.94.163.100

[o.meyer]

To find out the domain, that you have configured enter:

hostname -f

your domain is the part from the first point till the end.
You can use your router (gateway) as nameserver. Please try the following configuration (replace %your_domain% with your domain).

/etc/resolv.conf
-----------------------------------
search %your_domain%
nameserver 192.168.1.1
-----------------------------------

/etc/network/interfaces
-----------------------------------
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.1.112
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
-----------------------------------

Afterwards you have to restart the network.

/etc/init.d/networking restart

It works!! Hooray!!

It must have been the nameserver but that nameserver address I had in there is the same that is reported when I type ipconfig on my windows machine. But whatever if it works it works!!

[o.meyer]

About WOL.

When you started or restarted your system (before the system is booting the OS) you have to hit "DEL" or "F2" (depending on your BIOS manufacturer) to get into your BIOS settings.

Search an option called "Wake on LAN" and switch it on - afterwards save the configuration and exit the BIOS settings (save&exit). Have also a look for a setting to "restore ac after power loss" - this will start the system automatically after a blackout.

Best regards,

Olli
