HOWTO QUICKIE: POST INSTALL
Intro
This is intended to be short and efficient.
This HOWTO QUICKIE picks up where the HOWTO QUICKIE: Install Debian netinst left off.
It is suggested to do this "remotely" via ssh, if anything, for the copy & paste abilities. Putty does the trick for those in Windows. If you do opt to ssh into your new Debian box, you will need its IP address. As root, in the Debian box, type ifconfig and press enter. This should yield the IP address(es).
Begin
# Login with the new user (not root)
su -
# Enter the root password
NIC Junk
# If you want a static IP ...
cp /etc/network/interfaces /etc/network/interfaces.orig
vi /etc/network/interfaces
# See Network Interfaces: Static
# Reboot, log back in, and 'su -' back to root, if you so desire ...
# If you want a dynamic IP ...
# This is the default config of a Debian installation, do nothing.
# If you must, see Network Interfaces: Dynamic
# Reboot, log back in, and 'su -' back to root, if you so desire ...
# Configure DNS Servers
# See resolv.conf
Carry On
cp /etc/apt/sources.list /etc/apt/sources.list.orig
vi /etc/apt/sources.list
# See sources.list
apt-get update
apt-get upgrade
# Enter to select Y and continue
# If kernel or other "critical" upgrades, reboot ASAP, which is:
reboot
Message of the Day (motd)
cp /etc/motd /etc/motd.orig
vi /etc/motd
# Suggest you start editing on the 3rd line.
# Also, you do not need a following line break.
Customize
The best move here is to start hardening your new box.
