A MAC (Media Access Control) address is a number that identifies the network adapter(s) installed on your computer. Virtual windows for mac. The address is composed of up to 6 pairs of characters, separated by colons. You may need to provide your MAC address to a router in order to successfully connect to a network. Ipconfig in Mac OS X serves as a wrapper to the IPConfiguration agent, and can be used to control the Bootstrap Protocol and DHCP client from the command-line interface. Like most Unix -based operating systems, Mac OS X also uses ifconfig for more direct control over network interfaces, such as configuring static IP addresses.

If you momentarily forget where you are at a Mac OS X terminalsession, you might type 'ipconfig /all' or something equallyWindowish. You will get a response:
usage: ipconfig <command> <args>>
where <command> is one of waitall, getifaddr, ifcount, getoption, getpacket, set, setverbose
where <command> is one of waitall, getifaddr, ifcount, getoption, getpacket, set, setverbose
What's this? You already know you mistyped: on Mac OS X youprobably meant to run 'ifconfig -a' just as you would on Linux. But'ipconfig' is different, and is actually something goodto have in your bag of tricks.
Vlc media player for mac update. The first thing ipconfig can do for you is quickly give you allyour dhcp info:
$ ipconfig getpacket en0
op = BOOTREPLY
htype = 1
flags = 0
hlen = 6
hops = 0
xid = 1045997387
secs = 0
ciaddr = 0.0.0.0
yiaddr = 192.168.9.30
siaddr = 0.0.0.0
giaddr = 0.0.0.0
chaddr = 0:16:cb:8d:38:f7
sname =
file =
options:
Options count is 7
dhcp_message_type (uint8): ACK 0x5
subnet_mask (ip): 255.255.255.0
lease_time (uint32): 0x93a80
router (ip_mult): {192.168.9.254}
domain_name_server (ip_mult): {192.168.9.254}
server_identifier (ip): 192.168.9.254
end (none):
op = BOOTREPLY
htype = 1
flags = 0
hlen = 6
hops = 0
xid = 1045997387
secs = 0
ciaddr = 0.0.0.0
yiaddr = 192.168.9.30
siaddr = 0.0.0.0
giaddr = 0.0.0.0
chaddr = 0:16:cb:8d:38:f7
sname =
file =
options:
Options count is 7
dhcp_message_type (uint8): ACK 0x5
subnet_mask (ip): 255.255.255.0
lease_time (uint32): 0x93a80
router (ip_mult): {192.168.9.254}
domain_name_server (ip_mult): {192.168.9.254}
server_identifier (ip): 192.168.9.254
end (none):
There are shortcuts to the items listed under 'options':
$ ipconfig getoption en0 router
192.168.9.254
$ ipconfig getoption en0 domain_name_server
192.168.9.254 Install r for mac.
192.168.9.254
$ ipconfig getoption en0 domain_name_server
192.168.9.254 Install r for mac.
'ipconfig getifaddr en0' is a quick way to just get the ip address.You can also use ipconfig with its 'set' options to change an interfacefrom DHCP to manual or vice-versa. That's temporary; it doesn'twrite any start up files.
If you are having difficulty with DHCP, ipconfig has one more use: you can (as root) set verboselogging with 'ipconfig setverbose 1'. With that set, you getminor debugging info written to syslog (/var/log/system.log on my system), but you also get a separateBOOTP/DHCP log in /var/log/com.apple.IPConfiguration.bootp thatshows the full BOOTREQUEST/BOOTREPLY packet negotiation.
Think of ipconfig the next time you are looking for DHCP info ona Mac.
