Network Time Protocol (NTP) Client Configuration
NTP is a protocol for setting the real time clock on a system. There are numerous primary and
secondary servers available on the network. For more NTP information, and a list of available
NTP servers, see the following URL:
http://www.ntp.org/
You will need to have your network settings properly configured to reach an available NTP
server on your local network or the internet. To set the time and date, execute
ntpdate
with the
server of your choice. For example,
ntpdate –u ntp.ucsd.edu
The
–u
is required if the OpenArchitect switch is operating behind some types of firewalls.
If you wish for
ntpdate
to set your date and time automatically each time you boot,
uncomment the example
ntpdate
command line in
/etc/init.d/rcS
by removing the
#
sign.
ntpdate
returns the Universal Time (UTC, formerly Greenwich Mean Time, or GMT). To
display the localtime, set the
TZ
variable to the appropriate name and the number of hours offset
from UTC. For instance,
export TZ=PST8
for Pacific Standard Time offset from UTC by 8 hours. To set an environment variable, add the
entry to
/etc/profile
. Remember to
zsync
to make your changes permanent.
Network File System (NFS) Client Configuration
The OpenArchitect switch includes an NFS client for mounting remote file systems. You will
need to start NFS server processes in order to use NFS. You will need to start the following
servers:
/sbin/portmap
