Initial Debian System Configuration

On the first boot of the new Debian installation, the base-config application will be run. This will
do more configuration of the system. Please consult the Debian home page for help with this
process. I generally skip running the “

tasksel

” and “

dselect

” processes until I have tweaked the

configuration of my system as discussed next.

When running Linux on any of the IOP HBA-type CRBs (i.e., IQ80321, IQ80331, etc), they will
not have a real-time-clock (RTC) on board. As such, they will not retain the time across boots. To
address this, we can install either rdate or ntp. A side effect of this is that for every login, there is a
prompted to change the password. This is because password aging is enabled be default and the
date is wrong, thus confusing the system.

6.1.3

Maintaining System Time With Rdate

To enable the IA Linux host as an rdate server, issue the following commands on the server as root:

# /sbin/chkconfig time on

# /sbin/service xinetd restart

Then on the Intel XScale

®

microarchitecture-Linux target, issue the following commands to

download and install the rdate package. This only needs to be done once.

# apt-get install rdate

To manually update the time on the target:

# rdate 192.168.0.1

Add the following to the '/etc/rc.local' or create it when it does not exist:

rdate -s 192.168.0.1

and ensure that it is executable and is called on each boot:

# chmod 755 /etc/rc.local

# cd /etc/rc2.d; ln -s ../rc.local ./S99local

# cd /etc/rc3.d; ln -s ../rc.local ./S99local

# cd /etc/rc4.d; ln -s ../rc.local ./S99local

# cd /etc/rc5.d; ln -s ../rc.local ./S99local
