To reiterate our basic assumption, this guide assumes that the Ethernet
Interface in the FreeBSD system is named 'ed0'. This is the default
for NE-1000, NE-2000, WD/SMC models 8003, 8013 and Elite Ultra (8216)
network adapters.
Other models of network adapters may have different device names in
FreeBSD. Check the FAQ for specifics about your network adapter.
If you're not sure of the device name of your adapter, check the
FreeBSD FAQ to determine the device name for the card you have and
substitute that name (i.e.: 'de0', 'zp0', or similar) in the following
steps.
As was the case with the host name, the configuration for the FreeBSD system's Ethernet Interface may have been specified when the system was installed.
To display the configuration for the interfaces in your FreeBSD system (Ethernet and others), enter the following command:
# ifconfig -a
An example: <hr>
# ifconfig -a
ed0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 192.168.1.1 netmask 0xffffff00 broadcast 192.168.1.255
ether 01:02:03:04:05:06
lp0: flags=8810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1500
tun0: flags=8050<POINTOPOINT,RUNNING, MULTICAST> mtu 1500
sl0: flags=c010<POINTOPOINT,LINK2,MULTICAST> mtu 552
ppp0: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
inet 127.0.0.1 netmask 0xff000000
# _
<hr>
In this example, the following devices were displayed:
ed0: The Ethernet Interface
lp0: The Parallel Port Interface (ignored in this guide)
tun0: The "tunnel" device; This is the one ppp uses!
sl0: The SL/IP device (ignored in this guide)
ppp0: Another PPP device (ignored in this guide)
lo0: The "Loopback" device (ignored in this guide)
In this example, the 'ed0' device is up and running. The key indicators are:
UP",inet") address, (in this case, 192.168.1.1)If the line for the Ethernet card had shown something similar to: <hr>
ed0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
ether 01:02:03:04:05:06
<hr>
then the Ethernet card hasn't been configured yet.
If the configuration for the Ethernet interface is correct you can skip forward to Section 3.4, "Creating the list of other LAN hosts". Otherwise, proceed with the next section.
