Configuration of Ubuntu Server

Once the Ubuntu Server is up and running, I usually personalise the system this way:

1- Updating

nano -w /etc/apt/sources.list (remove CD-ROM reference and uncomment the universe repository + last 2 lines)
apt-get update
apt-get upgrade

2- Setting up the network permanently

nano -w /etc/network/interfaces

auto eth0
iface eth0 inet static
  address 192.168.0.2
  netmask 255.255.255.0
  gateway 192.168.0.1

apt-get install resolvconf
nano -w /etc/resolvconf/resolv.conf.d/base (basically copy the content of original)

search your.domain.com
# verizon for example
nameserver 4.2.2.1
nameserver 4.2.2.6

3- Remote access (OpenSSH Server)

apt-get install openssh-server

Optional Step:
nano -w /etc/ssh/sshd_config

# (Change to another port if necessary)
Port 22
# (uncomment so the banner is visible)
Banner /etc/issue.net

/etc/init.d/ssh restart

4- Custom Header

nano -w /etc/issue.net
nano -w /etc/motd.tail

5- Adjusting Resolution of the console

nano -w /boot/grub/menu.lst

# add to the end of the main boot line
# 1024x768@24-bits: vga=792
# 1280x1024@24-bits: vga=795

# defoptions=quiet splash vga=792
kernel /boot/vmlinuz-2.6.17-10-server root=/dev/sda2 ro quiet splash vga=792

use

custom configurations such as
/etc/issue

Just a command reminder for finding where the VMNet are bridged:
ps -ef | grep bridge
