Win2K).
Version 0.11
SYNOPSIS

# Works the same way on FreeBSD, OpenBSD, Solaris, Linux, OS X, WinNT (from Win2K).
# Note: due of Net::Ifconfig::Wrapper limitations 'inet' and 'down' commands
# are not working on WinNT. +/-alias are working, of course.

DESCRIPTION
This module provides a unified way to configure the network interfaces on FreeBSD, OpenBSD, Solaris, Linux, OS X, and WinNT (from Win2K)
systems.
Only "inet" (IPv4) and "ether" (MAC) addresses are supported at the moment
On Unixes this module calls the system "ifconfig" command to perform the actions. On Windows the functions from IpHlpAPI.DLL are called.
For all supported Unixes "Net::Ifconfig::Wrapper" expect "ifconfig" command to be "/sbin/ifconfig".
Module was tested on FreeBSD 4.7,4.8,5.3 (Intel), RedHat 6.2,7.3,8.0 (Intel), Win2000 Pro (Intel), OpenBSD 3.1 (SPARC), Solaris 7 (SPARC),
OS X 10.3 (aka Panther), OS X 10.4 (aka Tiger).
In MSWin32 family only WinNT is supported. In WinNT family only Win2K or later is supported.
The Net::Ifconfig::Wrapper methods
"Ifconfig(Command, Interface, Address, Netmask);"
The first and the last method of the "Net::Ifconfig::Wrapper" module. Do all the job. The particular action is described by the
$Command parameter.
$Command could be:
'list' "Ifconfig('list', '', '', '')" will return the reference to the hash contains the information about interfaces.
The structure of this hash is the following:
{IfaceName => {'status' => 0|1 # The status of the interface. 0 means down, 1 means up
'ether' => MACaddr, # The ethernet address of the interface if available
'descr' => Description, # The description of the interface if available
'inet' => {IPaddr1 => NetMask, # The IP address and his netmask, both are in AAA.BBB.CCC.DDD notation
IPaddr2 => NetMask,
...
},
...
};
Interface, Address, Netmask parameters are ignored.
The following programs are called:
FreeBSD "/sbin/ifconfig -a"
Solaris "/sbin/ifconfig -a"
OpenBSD "/sbin/ifconfig -A"
Linux "/sbin/ifconfig -a"
OS X "/sbin/ifconfig -a"
MSWin32 "GetAdaptersInfo" function from "IpHlpAPI.DLL"
Limitations:
OpenBSD: "/sbin/ifconfig -A" command is not returning information about MAC addresses so we are trying to get it from
'/usr/sbin/arp -a' command (first 'static' entry). If no one present the 'ff:ff:ff:ff:ff' address is returned.
MSWin32: "GetAdaptersInfo" function is not returning information about interface which have address 127.0.0.1 binded so
"Net::Ifconfig::Wrapper" have no ability to display it.
Not limitation but little problem: MSWin32 interface names are not human-readable, they looks like
"{843C2077-30EC-4C56-A401-658BB1E42BC7}" (on Win2K at least).
'inet' This function is used to set IPv4 address on interface. It have to be called as
Ifconfig('inet', $IfaceName, $Addr, $Mask);
$IfaceName is an interface name as displayed by 'list' command
$Addr is an IPv4 address in the "AAA.AAA.AAA.AAA" notation
$Mask is an IPv4 subnet mask in the "MMM.MMM.MMM.MMM" notation
The following actual "ifconfig" programs are called
FreeBSD "/sbin/ifconfig %Iface% inet %Addr% netmask %Mask% up"
Solaris "/sbin/ifconfig %Iface% inet %Addr% netmask %Mask% up"
OpenBSD "/sbin/ifconfig %Iface% inet %Addr% netmask %Mask% up"
Linux "/sbin/ifconfig %Iface% inet %Addr% netmask %Mask% up"
OS X "/sbin/ifconfig %Iface% inet %Addr% netmask %Mask% up"
MSWin32: nothing :(
Limitations:
MSWin32: I did not find the relaible way to recognize the "main" address on the Win32 network interface, so I have disabled
this functionality. If you know the way please let me know.
'up' Just a synonym for 'inet'
'down' This function is used to bring specified interface down. It have to be called as
Ifconfig('inet', $IfaceName, '', '');
$IfaceName is an interface name as displayed by 'list' command
Address and Netmask are ignored.
The following actual "ifconfig" programs are called
FreeBSD "/sbin/ifconfig %Iface% down"
Solaris "/sbin/ifconfig %Iface% down"
OpenBSD "/sbin/ifconfig %Iface% down"
Linux "/sbin/ifconfig %Iface% down"
OS X "/sbin/ifconfig %Iface% down"
MSWin32 nothing :(
Limitations:
MSWin32: I did not find the way to implement the 'up' command so I did not implement 'down'.
'+alias'
This function is used to set IPv4 alias address on interface. It have to be called as
Ifconfig('+alias', $IfaceName, $Addr, $Mask);
$IfaceName is an interface name as displayed by 'list' command
$Addr is an IPv4 address in the "AAA.AAA.AAA.AAA" notation
$Mask is an IPv4 subnet mask in the "MMM.MMM.MMM.MMM" notation
The following actual "ifconfig" programs are called
FreeBSD "/sbin/ifconfig %Iface% inet %Addr% netmask %Mask% alias"
Solaris "/sbin/ifconfig %Iface%:%Logic% inet %Addr% netmask %Mask% up"
OpenBSD "/sbin/ifconfig %Iface% inet %Addr% netmask %Mask% alias"
Linux "/sbin/ifconfig %Iface%:%Logic% inet %Addr% netmask %Mask% up"
OS X "/sbin/ifconfig %Iface% inet %Addr% netmask %Mask% alias"
MSWin32 "AddIPAddress" function from "IpHlpAPI.DLL"
First available logic interface is taken automatically for Solaris and Linux
'alias' Just a synonim for '+alias'
'-alias'
This function is used to remove IPv4 alias address from interface. It have to be called as
Ifconfig('-alias', $IfaceName, $Addr, '');
$IfaceName is an interface name as displayed by 'list' command
$Addr is an IPv4 address in the "AAA.AAA.AAA.AAA" notation
Netmask> parameter is ignored
The following actual "ifconfig" programs are called
FreeBSD "/sbin/ifconfig %Iface% inet %Addr% -alias"
Solaris "/sbin/ifconfig %Iface%:%Logic% down"
OpenBSD "/sbin/ifconfig %Iface% inet %Addr% -alias"
Linux "/sbin/ifconfig %Iface%:%Logic% down"
OS X "/sbin/ifconfig %Iface% inet %Addr% -alias"
MSWin32 "DeleteIPAddress" function from "IpHlpAPI.DLL"
Appropriate logic interface is obtained automatically for Solaris and Linux
On success "Ifconfig(...)" returns the defined value. Actually, it is a reference to the array contains the output of the actual
"ifconfig" program called.
In case of troubles "Ifconfig(...)" returns 'undef' value, $@ variable contains the error message.
EXPORT
None by default.
