DESCRIPTION

40       IO::Interface::Simple allows you to interrogate and change network
41       interfaces. It has overlapping functionality with Net::Interface, but
42       might compile and run on more platforms.
43
44   Class Methods
45       $interface = IO::Interface::Simple->new('eth0')
46           Given an interface name, new() creates an interface object.
47
48       @iflist = IO::Interface::Simple->interfaces;
49           Returns a list of active interface objects.
50
51       $interface = IO::Interface::Simple->new_from_address('192.168.0.1')
52           Returns the interface object corresponding to the given address.
53
54       $interface = IO::Interface::Simple->new_from_index(2)
55           Returns the interface object corresponding to the given numeric
56           index. This is only supported on BSD-ish platforms.
57
58   Object Methods
59       $name = $interface->name
60           Get the name of the interface. The interface object is also
61           overloaded so that if you use it in a string context it is the same
62           as calling name().
63
64       $index = $interface->index
65           Get the index of the interface. This is only supported on BSD-like
66           platforms.
67
68       $addr = $interface->address([$newaddr])
69           Get or set the interface's address.
70
71       $addr = $interface->broadcast([$newaddr])
72           Get or set the interface's broadcast address.
73
74       $addr = $interface->netmask([$newmask])
75           Get or set the interface's netmask.
76
77       $addr = $interface->hwaddr([$newaddr])
78           Get or set the interface's hardware address.
79
80       $addr = $interface->mtu([$newmtu])
81           Get or set the interface's MTU.
82
83       $addr = $interface->metric([$newmetric])
84           Get or set the interface's metric.
85
86       $flags = $interface->flags([$newflags])
87           Get or set the interface's flags. These can be ANDed with the IFF
88           constants exported by IO::Interface or Net::Interface in order to
89           interrogate the state and capabilities of the interface. However,
90           it is probably more convenient to use the broken-out methods listed
91           below.
92
93       $flag = $interface->is_running([$newflag])
94       $flag = $interface->is_broadcast([$newflag])
95       $flag = $interface->is_pt2pt([$newflag])
96       $flag = $interface->is_loopback([$newflag])
97       $flag = $interface->is_promiscuous([$newflag])
98       $flag = $interface->is_multicast([$newflag])
99       $flag = $interface->is_notrailers([$newflag])
100       $flag = $interface->is_noarp([$newflag])
101           Get or set the corresponding configuration parameters. Note that
102           the operating system may not let you set some of these.
