Hi Klaus,
thank you very much for your well-done HowTo. I need NTP running at
the foxboard and therefore I was glad to find this help.
It worked fine for me, and NTP is running perfectly now at my
foxboard. Just some notes:
1. In my setup there was no DNS server defined in /etc/resolv.conf.
For this reason NTP could not find the servers. I assume this is
clear for the normal developer, but I am a beginner.
2. There seems to be a small typo in your Howto in the post file:
Bug?: file files/etc/default/rcS /etc/defaultrcS mode=0666
My solution: directory /etc/default
file files/etc/default/rcS /etc/default/rcS mode=0666
3. I would like to use ntpq and ntpdc also, but at the moment I have
no glue how to make or compile them.
4. I would like to use the post file to add more of my application to
the fimage, for example a small website. I do not understand the
syntax of the post file and up to now I was not able to find any
documentation or any other example than yours.
Can anybody give me a link to the relevant documentation?
5. As I understand the history, the original code comes from
www.ntp.org (with a configure-utility, but without a makefile). Then
acme-systems people did some configuration and produced the makefile.
In your HowTo you described how to use the makefile from acme-
systems. For me it is black magic what the acme-systems people did.
If I would understand this step, maybe I would be able to use the
actual version of www.ntp.org and maybe I would be able to activate
ntpq and ntpdc.
Can anybody explain me the black magic of configuring the NTP package
for the foxboard?
