Sync Solaris System Clock With PDC Using Cron
Hi,

I currently use the ntpdate and date command to sync the internal clock source of my Solaris systems to the primary domain controller.


Code:
 
admin@myserver # ntpdate -d -u 192.168.???.???
14 Jan 17:42:02 ntpdate[929]: ntpdate 3-5.93e+sun 03/06/05 23:16:45 (1.4)
transmit(192.168.???.???)
receive(192.168.???.???)
transmit(192.168.???.???)
receive(192.168.???.???)
transmit(192.168.???.???)
receive(192.168.???.???)
transmit(192.168.???.???)
receive(192.168.???.???)
transmit(192.168.43.1)
server 192.168.???.???, port 123
stratum 1, precision -6, leap 00, trust 000
refid [LOCL], delay 0.04144, dispersion 0.00035
transmitted 4, in filter 4
reference time:    cef8b7b1.ac10624d  Thu, Jan 14 2010  7:20:49.672
originate timestamp: cef9493b.f4000000  Thu, Jan 14 2010 17:41:47.953
transmit timestamp:  cef9494a.90dee000  Thu, Jan 14 2010 17:42:02.565
filter delay:  0.04189  0.04146  0.04144  0.04146
                   0.00000  0.00000  0.00000  0.00000
filter offset: -14.6115 -14.6121 -14.6125 -14.6128
                   0.000000 0.000000 0.000000 0.000000
delay 0.04144, dispersion 0.00035
offset -14.612542
14 Jan 17:42:02 ntpdate[929]: step time server 192.168.???.??? offset -14.612542 sec


I then take the output of the offset and use the following to slowly sync

Code:
date -a -14.612542

Is it possible to run a .sh executable script that would combine both commands and take the offset value of the ntpdate command and automatically insert the value into the date -a command. I would then like to run in a cron.

Thanks in advance

tgt-setup-lun

tgt-setup-lun(8)					      System Manager's Manual						  tgt-setup-lun(8)

NAME

       tgt-setup-lun - creates a target, adds a device to the target and defines initiators that can connect to the target

SYNOPSIS

       tgt-setup-lun -d device -n target_name [initiator_IP1 initiator_IP2 ...] [-h]

DESCRIPTION

       Starts tgtd if necessary and creates a target according to the supplied target_name. The format of the target name is as follows:
       iqn.2001-04.com.<hostname>-<target_name> The target name must be unique.

       The  script then adds the requested device to the target. If specific IP addresses are defined, it adds them to the list of allowed initia-
       tors for that target. If no IP addresses is defined, it defines that the target accepts any initiator.

EXAMPLES

       Create a target that uses /dev/sdb1 and allows connections only from 192.168.10.81:
       tgt-setup-lun -d /dev/sdb1 -n my_target 192.168.10.81

       Create a target that uses /dev/sdb1 and allows connections only from 192.168.10.81 and 192.168.10.82:
       tgt-setup-lun -d /dev/sdb1 -n my_target 192.168.10.81 192.168.10.82

       Create a target that uses /dev/sdb1 and allows connections from any initiator:
       tgt-setup-lun -d /dev/sdb1 -n my_target

       Display help:
       tgt-setup-lun -h
