ipconfig command in UNIX?

zo

Alo alo,



was wondering what the equivalent(s) of the DOS ipconfig and ipconfig /all commands are.



Would like to get a good lowdown on the network, MAC addresses, etc.



Yes, I know I can simply click on "About this Mac" and select Sys Profiler...

ifconfig is the command you are looking for



The following options are available:



address

For the DARPA-Internet family, the address is either a host name

present in the host name data base, hosts(5), or a DARPA Internet

address expressed in the Internet standard ``dot notation''.



It is also possible to use the CIDR notation (also known as the

slash notation) to include the netmask. That is, one can specify

an address like 192.168.0.1/16.



address_family

Specify the address family which affects interpretation of the

remaining parameters. Since an interface can receive transmis-

sions in differing protocols with different naming schemes, spec-

ifying the address family is recommended. The address or proto-

col families currently supported are ``inet'', ``inet6'',



dest_address

Specify the address of the correspondent on the other end of a

point to point link.



interface

This parameter is a string of the form ``name unit'', for exam-

ple, ``en0''.



The following parameters may be set with ifconfig:



add Another name for the alias parameter. Introduced for compatibil-

ity with BSD/OS.



alias Establish an additional network address for this interface. This

is sometimes useful when changing network numbers, and one wishes

to accept packets addressed to the old interface. If the address

is on the same subnet as the first network address for this

interface, a netmask of 0xffffffff has to be specified.



-alias Remove the network address specified. This would be used if you

incorrectly specified an alias, or it was no longer needed. If

you have incorrectly set an NS address having the side effect of

specifying the host portion, removing all NS addresses will allow

you to respecify the host portion.



anycast

(Inet6 only.) Specify that the address configured is an anycast

address. Based on the current specification, only routers may

configure anycast addresses. Anycast address will not be used as

source address of any of outgoing IPv6 packets.



arp Enable the use of the Address Resolution Protocol (arp(4)) in

mapping between network level addresses and link level addresses

(default). This is currently implemented for mapping between

DARPA Internet addresses and IEEE 802 48-bit MAC addresses (Eth-

ernet, FDDI, and Token Ring addresses).



-arp Disable the use of the Address Resolution Protocol (arp(4)).



broadcast

(Inet only.) Specify the address to use to represent broadcasts

to the network. The default broadcast address is the address

with a host part of all 1's.



debug Enable driver dependent debugging code; usually, this turns on

extra console error logging.



-debug Disable driver dependent debugging code.



delete Another name for the -alias parameter.



down Mark an interface ``down''. When an interface is marked

``down'', the system will not attempt to transmit messages

through that interface. If possible, the interface will be reset

to disable reception as well. This action does not automatically

disable routes using the interface.



ether Another name for the lladdr parameter.



lladdr addr

Set the link-level address on an interface. This can be used to

e.g. set a new MAC address on an ethernet interface, though the

mechanism used is not ethernet-specific. The address addr is

specified as a series of colon-separated hex digits. If the

interface is already up when this option is used, it will be

briefly brought down and then brought back up again in order to

ensure that the receive filter in the underlying ethernet hard-

ware is properly reprogrammed.



media type

If the driver supports the media selection system, set the media

type of the interface to type. Some interfaces support the mutu-

ally exclusive use of one of several different physical media

connectors. For example, a 10Mb/s Ethernet interface might sup-

port the use of either AUI or twisted pair connectors. Setting

the media type to ``10base5/AUI'' would change the currently

active connector to the AUI port. Setting it to ``10baseT/UTP''

would activate twisted pair. Refer to the interfaces' driver

specific documentation or man page for a complete list of the

available types.



mediaopt opts

If the driver supports the media selection system, set the speci-

fied media options on the interface. The opts argument is a

comma delimited list of options to apply to the interface. Refer

to the interfaces' driver specific man page for a complete list

of available options.



-mediaopt opts

If the driver supports the media selection system, disable the

specified media options on the interface.



tunnel src_addr dest_addr

(IP tunnel devices only.) Configure the physical source and des-

tination address for IP tunnel interfaces (gif(4)). The argu-

ments src_addr and dest_addr are interpreted as the outer

source/destination for the encapsulating IPv4/IPv6 header.



deletetunnel

Unconfigure the physical source and destination address for IP

tunnel interfaces previously configured with tunnel.



create Create the specified network pseudo-device. If the interface is

given without a unit number, try to create a new device with an

arbitrary unit number. If creation of an arbitrary device is

sucessful, the new device name is printed to standard output.



destroy

Destroy the specified network pseudo-device.



plumb Another name for the create parameter. Included for Solaris com-

patibility.



unplumb

Another name for the destroy parameter. Included for Solaris

compatibility.



metric n

Set the routing metric of the interface to n, default 0. The

routing metric is used by the routing protocol (routed(8)).

Higher metrics have the effect of making a route less favorable;

metrics are counted as addition hops to the destination network

or host.



mtu n Set the maximum transmission unit of the interface to n, default

is interface specific. The MTU is used to limit the size of

packets that are transmitted on an interface. Not all interfaces

support setting the MTU, and some interfaces have range restric-

tions.



netmask mask

(Inet only.) Specify how much of the address to reserve for sub-

dividing networks into sub-networks. The mask includes the net-

work part of the local address and the subnet part, which is

taken from the host field of the address. The mask can be speci-

fied as a single hexadecimal number with a leading `0x', with a

dot-notation Internet address, or with a pseudo-network name

listed in the network table networks(5). The mask contains 1's

for the bit positions in the 32-bit address which are to be used

for the network and subnet parts, and 0's for the host part. The

mask should contain at least the standard network portion, and

the subnet field should be contiguous with the network portion.



The netmask can also be specified in CIDR notation after the

address. See the address option above for more information.



prefixlen len

(Inet6 only.) Specify that len bits are reserved for subdividing

networks into sub-networks. The len must be integer, and for

syntactical reason it must be between 0 to 128. It is almost

always 64 under the current IPv6 assignment rule. If the parame-

ter is omitted, 64 is used.



remove Another name for the -alias parameter. Introduced for compati-

bility with BSD/OS.



link[0-2]

Enable special processing of the link level of the interface.

These three options are interface specific in actual effect, how-

ever, they are in general used to select special modes of opera-

tion. An example of this is to enable SLIP compression, or to

select the connector type for some Ethernet cards. Refer to the

man page for the specific driver for more information.



-link[0-2]

Disable special processing at the link level with the specified

interface.



up Mark an interface ``up''. This may be used to enable an inter-

face after an ``ifconfig down''. It happens automatically when

setting the first address on an interface. If the interface was

reset when previously marked down, the hardware will be re-ini-

tialized.



Ifconfig displays the current configuration for a network interface when

no optional parameters are supplied. If a protocol family is specified,

ifconfig will report only the details specific to that protocol family.



If the driver does supports the media selection system, the supported

media list will be included in the output.



If the -m flag is passed before an interface name, ifconfig will display

all of the supported media for the specified interface. If -L flag is

supplied, address lifetime is displayed for IPv6 addresses, as time off-

set string.



Optionally, the -a flag may be used instead of an interface name. This

flag instructs ifconfig to display information about all interfaces in

the system. The -d flag limits this to interfaces that are down, and -u

limits this to interfaces that are up. When no arguments are given, -a

is implied.



The -l flag may be used to list all available interfaces on the system,

with no other additional information. Use of this flag is mutually

exclusive with all other flags and commands, except for -d (only list

interfaces that are down) and -u (only list interfaces that are up).



Only the super-user may modify the configuration of a network interface.

crikey! thanks!!!

The info tab in Network Utility also gives you all the info for your network interfaces. If you want to see what ports and IPs your listening on you can use:



sudo netstat -ln
