Perl version: This is perl, v5.10.1 (*) built for
x86_64-linux-gnu-thread-multi
OS version: Ubuntu 10.04 LTS: Linux sideshowbob 2.6.32-37-server
#81-Ubuntu SMP Fri Dec 2 20:49:12 UTC 2011 x86_64 GNU/Linux
Sys::HostAddr version 0.95 - Fetching with LWP:
http://www.perl.org/CPAN/authors/id/J/JK/JKISTER/Sys-HostAddr-0.95.tgz
Running this perl script:
------------------------------
use Sys::HostAddr;
use Data::Dumper;
$s = Sys::HostAddr->new();
print Dumper $s->ip();
------------------------------
Produces this output:
------------------------------
$VAR1 = {
'lo' => [
{
'netmask' => '255.0.0.0',
'address' => '127.0.0.1'
}
],
'eth1' => [
{
'netmask' => '255.255.255.0',
'address' => '192.168.7.104'
}
],
'eth0' => [
{
'netmask' => '255.255.255.0',
'address' => '192.168.0.104'
}
]
};
------------------------------
but "ip addr show" gives:
------------------------------
david@sideshowbob:~$ ip addr show

------------------------------
Addresses 192.168.0.101 on eth0 and 192.168.7.101 on eth1 are not
included in the results of Sys::HostAddr->ip, behaviour is similar for
other methods, these addresses are never seen by the perl module.
