The Perfect Setup - Ubuntu 6.06 LTS Server (Dapper Drake) - Page 3

On Step 5: i.e. Configure The Network

I wasn't able to connect with Putty after completing steps 5 thru 6. So I restarted still no change.

I then remembered that I had to add the "dns-namserver XX.XXX.XX.XX XXX.XX.XXX.XX. to the /etc/network/interfaces when it came to Ubuntu BrezzyBadger 5.10 perfect "ISP-Server Setup - Ubuntu 5.10 "Breezy Badger"" (the sister to this guide; but for Brezzy) yesterday. At the bottom of the info you add your DNS servers addresses. Replace the XXX's for whatever it or they are.

Like this:

from:

address 192.168.0.100
        netmask 255.255.255.0
        network 192.168.0.0
        broadcast 192.168.0.255
        gateway 192.168.0.1

address 192.168.0.100
        netmask 255.255.255.0
        network 192.168.0.0
        broadcast 192.168.0.255
        gateway 192.168.0.1
        dns-nameserver XX.XXX.XXX.XXX XXX.XX.XX.XX

You don't need to enable the root account. You can stay logged at root using :

sudo -s

Until I did this to the /etc/hostname file, I kept receiving permission errors when setting up the mysql root passwords following the instructions on the next page. Thanks for posting this tip!

Great tutorial!!! Love it. Thanks

On the steps to configure hostname, it does not work to only do the steps listed.

I found that I had to edit /etc/hostname

We found it necessary to also manually setup our DNS server when not using DHCP. This was done by creating a file:
/etc/resolv.conf

The file should look something like this:

search domain.tld
nameserver xxx.xxx.xxx.xxx

It is mutch easyer if you shutdown DHCP then you can configure it in the installation.

    I've gotten to this point with very little trouble.  Very clear and concise instructions.  I look forward to going through many more. 

Again...  Thank you  

In Part 5, "Configure the network", the author of this very useful guide forgets to mention something:

Then restart your network:

/etc/init.d/networking restart

What he doesn't mention is:

You're not supposed to type that '/etc/init.d/networking restart' in vi          The '/' that takes you to the bottom of the screen is the start of the search function in vi.

First save your work (press <esc>, press the colon and type wq followed by <enter>) and at the command line type the command.

It's true, because I was stuck until I emailed the Ubuntu Forum, and Wim Sturkenboom kindly explained me what I was doing wrong.

Hopefully you'll find this useful, too.  (Thank you, Wim!)
