A new serial number can be generated in the event that yours is missing or invalid. Apple requires a valid proof of purchase to request a replacement serial number submitted via fax or email. The following guidelines will help you to determine what is best for you.
I had a doubt regarding how the file size changes and needed some advice on the same
So I have this file say abc.txt.. Size was 10000. Now inside the file when I go and I replace all the number 7 numerals with number 4 file size changed to 9984. Any idea why and how ?? (8 Replies)
Hello!
I am working on an application which reads environmental instruments which have serial ports. The application requires a serial port to be present to talk to the device (i.e. /dev/ttyS0 ). In some instances the environmental devices will be 100's of yards away from the computer, so a... (5 Replies)

Net::DNS::RR::SOA(3) User Contributed Perl Documentation Net::DNS::RR::SOA(3)NAME
Net::DNS::RR::SOA - DNS SOA resource record
SYNOPSIS
use Net::DNS;
$rr = new Net::DNS::RR('name SOA mname rname 0 14400 3600 1814400 3600');
DESCRIPTION
Class for DNS Start of Authority (SOA) resource records.
METHODS
The available methods are those inherited from the base class augmented by the type-specific methods defined in this package.
Use of undocumented package features or direct access to internal data structures is discouraged and could result in program termination or
other unpredictable behaviour.
mname
$mname = $rr->mname;
$rr->mname( $mname );
The domain name of the name server that was the original or primary source of data for this zone.
rname
$rname = $rr->rname;
$rr->rname( $rname );
The mailbox which identifies the person responsible for maintaining this zone.
serial
$serial = $rr->serial;
$serial = $rr->serial(value);
Unsigned 32 bit version number of the original copy of the zone. Zone transfers preserve this value.
RFC1982 defines a strict (irreflexive) partial ordering for zone serial numbers. The serial number will be incremented unless the
replacement value argument satisfies the ordering constraint.
refresh
$refresh = $rr->refresh;
$rr->refresh( $refresh );
A 32 bit time interval before the zone should be refreshed.
retry
$retry = $rr->retry;
$rr->retry( $retry );
A 32 bit time interval that should elapse before a failed refresh should be retried.
expire
$expire = $rr->expire;
$rr->expire( $expire );
A 32 bit time value that specifies the upper limit on the time interval that can elapse before the zone is no longer authoritative.
minimum
$minimum = $rr->minimum;
$rr->minimum( $minimum );
The unsigned 32 bit minimum TTL field that should be exported with any RR from this zone.
Zone Serial Number Management
The internal logic of the serial() method offers support for several widely used zone serial numbering policies.
Strictly Sequential
$successor = $soa->serial( SEQUENTIAL );
The existing serial number is incremented modulo 2**32 because the value returned by the auxiliary SEQUENTIAL() function can never satisfy
the serial number ordering constraint.
Date Encoded
$successor = $soa->serial( YYYYMMDDxx );
The 32 bit value returned by the auxiliary YYYYMMDDxx() function will be used if it satisfies the ordering constraint, otherwise the serial
number will be incremented as above.
Serial number increments must be limited to 100 per day for the date information to remain useful.
Time Encoded
$successor = $soa->serial( UNIXTIME );
The 32 bit value returned by the auxiliary UNIXTIME() function will used if it satisfies the ordering constraint, otherwise the existing
serial number will be incremented as above.
