Type:
dmesg | grep -i ether
If you have an Ethernet card recognized by one of the drivers, you will
get back something like:
vvv---------------------------------------------------------------------------
de0 <Digital DC21040 Ethernet> rev 35 int a irq 11 on pci0:6
de0: DC21040 [10Mb/s] pass 2.3 Ethernet address 00:80:48:e8:1b:b1
^^^---------------------------------------------------------------------------
^^^ this will be different depending on your ethernet interface
Type:
ifconfig -a
This should list all the configured ethernet interfaces in your
machine, for example:
vvv---------------------------------------------------------------------------
lp0: flags=810<POINTOPOINT,SIMPLEX> mtu 1500
de0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 198.0.250.211 netmask 0xffffff00 broadcast 198.0.250.255
tun0: flags=10<POINTOPOINT> mtu 1500
sl0: flags=c010<POINTOPOINT,LINK2,MULTICAST> mtu 552
lo0: flags=8009<UP,LOOPBACK,MULTICAST> mtu 16384
inet 127.0.0.1 netmask 0xff000000
^^^---------------------------------------------------------------------------
lp0 = parallel port (ignore)
tun0 = tunnel device (ignore)
sl0 = SLIP device (ignore)
lo0 = loopback (important)
de0 = ethernet card driver from dmesg (important)
Look in /etc/sysconfig; you will see a section dimilar to this:
vvv---------------------------------------------------------------------------
#
# Set to the list of network devices on this host. You must have an
# ifconfig_${network_interface} line for each interface listed here.
# for example:
#
# network_interfaces="ed0 sl0 lo0"
# ifconfig_ed0="inet 10.0.0.1 netmask 0xffffff00"
# ifconfig_sl0="inet 10.0.1.0 netmask 0xffffff00"
#
network_interfaces="de0 lo0"
ifconfig_lo0="inet localhost"
ifconfig_de0="inet 198.0.250.211 netmask 0xffffff00"
^^^---------------------------------------------------------------------------
Most likely, your "network_interfaces" line is incorrect, and does not
have the right interface name on it.
If you do not have an ethernet device in dmesg, then either there is not
a driver for your card, or (more likely) your card is not configured
correctly.
If the card is there, and you list the full dmesg instead of grepping
it, you may find that your card has an interrupt or address range
conflict with some other card, and isn't being probed. You should
reconfigure the card (change jumpers, or run a setup program) and
then try again.
