DESCRIPTIONIO::Interface::Simple allows you to interrogate and change network
interfaces. It has overlapping functionality with Net::Interface, but
might compile and run on more platforms.
Class Methods
$interface = IO::Interface::Simple->new('eth0')
Given an interface name, new() creates an interface object.
@iflist = IO::Interface::Simple->interfaces;
Returns a list of active interface objects.
$interface = IO::Interface::Simple->new_from_address('192.168.0.1')
Returns the interface object corresponding to the given address.
$interface = IO::Interface::Simple->new_from_index(2)
Returns the interface object corresponding to the given numeric
index. This is only supported on BSD-ish platforms.
Object Methods
$name = $interface->name
Get the name of the interface. The interface object is also
overloaded so that if you use it in a string context it is the same
as calling name().
$index = $interface->index
Get the index of the interface. This is only supported on BSD-like
platforms.
$addr = $interface->address([$newaddr])
Get or set the interface's address.
$addr = $interface->broadcast([$newaddr])
Get or set the interface's broadcast address.
$addr = $interface->netmask([$newmask])
Get or set the interface's netmask.
$addr = $interface->hwaddr([$newaddr])
Get or set the interface's hardware address.
$addr = $interface->mtu([$newmtu])
Get or set the interface's MTU.
$addr = $interface->metric([$newmetric])
Get or set the interface's metric.
$flags = $interface->flags([$newflags])
Get or set the interface's flags. These can be ANDed with the IFF
constants exported by IO::Interface or Net::Interface in order to
interrogate the state and capabilities of the interface. However,
it is probably more convenient to use the broken-out methods listed
below.
$flag = $interface->is_running([$newflag])
$flag = $interface->is_broadcast([$newflag])
$flag = $interface->is_pt2pt([$newflag])
$flag = $interface->is_loopback([$newflag])
$flag = $interface->is_promiscuous([$newflag])
$flag = $interface->is_multicast([$newflag])
$flag = $interface->is_notrailers([$newflag])
$flag = $interface->is_noarp([$newflag])
Get or set the corresponding configuration parameters. Note that
the operating system may not let you set some of these.
