- ifconfig
- _________________________________________________________________
- Display a list of all attached interfaces, with a short status
- report for each.
-

- ifconfig <interface>
- _________________________________________________________________
- Display an extended status report of the interface.
-
- >> Example: The command 'ifconfig tnc0' produces a display of
- the form:
-
- ................................................................
- :tnc0 IP addr ns9bob MTU 256 Link encap AX25 :
- : Link addr NS9BOB-5 :
- : flags 1 trace 0x0 netmask 0x44ffffff broadcast uk :

- : OUT: 9 pkts :

-
- _________________________________________________________________
- ifconfig <interface> broadcast <broadcast_ip_address>
- _________________________________________________________________
- Set the broadcast address for the interface.
-
- The <broadcast_ip_address> takes the form of an IP address with
- 1's in the host part of the address. This is related to the
- 'netmask' sub-command described below.
-
- See also the 'arp' command.
-
- >> Examples: ifconfig tnc0 broadcast 44.255.255.255
- ifconfig tnc0 broadcast uk
- (where uk.ampr.org is in DOMAIN.TXT)
-
-
- _________________________________________________________________
- ifconfig <interface> description ["<description>"]
- _________________________________________________________________
- Set the interface description. If no string is supplied, the
- current description is cleared. The description is displayed
- with the 'ifconfig <interface>' command and with mailbox
- commands.
-
- >> Example: ifconfig tnc0 description "144.625 MHz port"
-
-
- _________________________________________________________________
- ifconfig <interface> encapsulation
- none|ax25|encap|ether|slip|netrom|ppp
- _________________________________________________________________
- Sets the encapsulation for <interface>.
-
- The 'encap' option is used when it is required to encapsulate
- AMPR packets within another IP datagram for transmission over
- other networks (for example, over the "real" Internet). This is
- necessary because the AMPRNET has a flat namespace (all names are
- in the single ".ampr.org" domain), and this causes problems with
- Internet.
-
- >> Example: ifconfig tnc0 encapsulation ax25
-
-
- _________________________________________________________________
- ifconfig <interface> forward <forward-interface>
- _________________________________________________________________
- Set a forwarding interface for multiple channel interfaces. When
- forwarding is defined, all output destined for <interface> is
- redirected to <forward-interface>.
-
- To remove forwarding, set <forward-interface> to <interface>.
-
- >> Example: ifconfig tnc0 forward sl0
-
-
- _________________________________________________________________
- ifconfig <interface> ipaddress <ipaddress>
- _________________________________________________________________
- Set the IP address for this interface. For hosts with only one
- interface, the interface address is usually the same as the host
- address.
-
- It may be necessary to set an IP address when a system acts as a
- gateway to the Internet; for example, via an Ethernet adapter.
- (Note that 44.x.x.x addresses are NOT connected to the Internet).
-
- See also the 'hostname' and 'ip address' commands.
-
- >> Example: ifconfig en0 ipaddress 123.45.6.7
-
-
- _________________________________________________________________
- ifconfig <interface> linkaddress <callsign> | <ether_address>
- _________________________________________________________________
- Set the hardware dependent address for this interface.
-
- >> Examples: ifconfig tnc0 linkaddress NS9BOB-5
- ifconfig en0 linkaddress 00:11:22:33:44:55
-
-
- _________________________________________________________________
- ifconfig <interface> mtu <mtu>
- _________________________________________________________________
- Set the Maximum Transmission Unit (MTU) in bytes for this
- interface.
-
- See the 'attach' and 'tcp' commands for more information on MTU
- settings.
-
- >> Example: ifconfig tnc0 mtu 1588
-
-
- _________________________________________________________________
- ifconfig <interface> netmask <hex_net_mask>
- _________________________________________________________________
- Set the sub-net mask for this interface. The <hex_net_mask>
- takes the form of an IP address with 1's in the network and
- subnet parts of the address, and 0's in the host part of the
- address, expressed as a hexadecimal number. This is related to
- the 'broadcast' sub-command. See also the 'route' command.
-
- >> Example: ifconfig tnc0 netmask 0xff000000
- (for a Class A network such as 44.x.x.x)
-
-
- _________________________________________________________________
- ifconfig <interface> rxbuf <buffer_size>
- _________________________________________________________________
- Set the receive buffer size.
