Hi,
I've got a Sun Solaris machine with host ID (840f8e57) and MAC address (0:14:4f:f:8e:57), how do I:
1. Write the MAC address in standard (IEEE 802) format, i.e. xx-xx-xx-xx-xx-xx? Do I need to add 0's before or after the 'f', i.e. 00-14-4f-0f-8e-57 or 00-14-4f-f0-8e-57?

Hello, I need to write a program using C language which allow me to change the IP and MAC addresses of a given interface...

four interfaces with ifconfig
all interfaces have the same mac. If is not set for unique.

net::arp
ARP(3pm) User Contributed Perl Documentation ARP(3pm)NAME
ARP - Perl extension for creating ARP packets
SYNOPSIS
use Net::ARP;
Net::ARP::send_packet('lo', # Device
'127.0.0.1', # Source IP
'127.0.0.1', # Destination IP
'aa:bb:cc:aa:bb:cc', # Source MAC
'aa:bb:cc:aa:bb:cc', # Destinaton MAC
'reply'); # ARP operation
$mac = Net::ARP::get_mac("eth0");
print "$mac
";
$mac = Net::ARP::arp_lookup($dev,"192.168.1.1");
print "192.168.1.1 has got mac $mac
";
IMPORTANT
Version 1.0 will break with the API of PRE-1.0 versions, because the return value of arp_lookup() and get_mac() will no longer be passed as
parameter, but returned! I hope this decision is ok as long as we get a cleaner and more perlish API.
DESCRIPTION
This module can be used to create and send ARP packets and to get the mac address of an ethernet interface or ip address.
send_packet()
Net::ARP::send_packet('lo', # Device
'127.0.0.1', # Source IP
'127.0.0.1', # Destination IP
'aa:bb:cc:aa:bb:cc', # Source MAC
'aa:bb:cc:aa:bb:cc', # Destinaton MAC
'reply'); # ARP operation
I think this is self documentating.
ARP operation can be one of the following values:
request, reply, revrequest, revreply, invrequest, invreply.
The default ARP operation is reply.
get_mac()
$mac = Net::ARP::get_mac("eth0");
This gets the MAC address of the eth0 interface and stores
it in the variable $mac. The return value is "unknown" if
the mac cannot be looked up.
arp_lookup()
$mac = Net::ARP::arp_lookup($dev,"192.168.1.1");
This looks up the MAC address for the ip address 192.168.1.1
and stores it in the variable $mac. The return value is
"unknown" if the mac cannot be looked up.
