DESCRIPTION
IO::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.
