I want a shell script which will move certain .jar files from a specified location (say /publish/content) to (/publish/archive) on every saturday morning 6 am.
One more thing to add is that before moving files it must check free space at (/publish/archive), if it is more than 60 %... (7 Replies)
All here, thank you for listening. Now I've set up a Linux NTP server by adding a external windows NTP server in /etc/ntp.conf. Then I start the ntpd daemon. But how often does the Linux NTP server update its time with the external NTP server? I've looked up everywhere but found no information... (1 Reply)

Good morning,

Dear All,
Today, somewhere around 7:30 GMT (2:30 PM Eastern Time) www.unix.com will go down for what we hope is around 15 - 20 minutes as we change out some hardware on the server.
Thank you for your patience and support.

There is one server in my company where the time is out of sync.
When I checked (compared with other servers whose time is correct), the XNTPD variable in /etc/rc.config.d/netdaemons was set as 0.
I changed this to 1, and tried restarting the xntpd process with :
# /sbin/init.d/xntpd start

net::ntp
Net::NTP(3pm) User Contributed Perl Documentation Net::NTP(3pm)NAME
Net::NTP - Perl extension for decoding NTP server responses
SYNOPSIS
use Net::NTP qw(get_ntp_response);
my %response = get_ntp_response();
ABSTRACT
All this module does is send a packet to an NTP server and then decode the packet received into it's respective parts - as outlined in
RFC1305 and RFC2030.
DESCRIPTION
This module exports a single method (get_ntp_response) and returns an associative array based upon RFC1305 and RFC2030. The response from
the server is "humanized" to a point that further processing of the information received from the server can be manipulated. For example:
timestamps are in epoch, so one could use the localtime function to produce an even more "human" representation of the timestamp.
EXPORT
get_ntp_response(<server>, <port>);
This module exports a single method - get_ntp_response. It takes the server as the first argument (localhost is the default) and port to
send/recieve the packets (ntp or 123 bu default). It returns an associative array of the various parts of the packet as outlined in
RFC1305. It "normalizes" or "humanizes" various parts of the packet. For example: all the timestamps are in epoch, NOT hexidecimal.
