I hope this is helpful to the group--


   Networking with generic NE2000 cards, `Linksys' for example

This outlines how I networked my two FreeBSD boxes using fairly
inexpensive 10Mb/sec PCI NE2000 clone card.  If you have similar
hardware, these notes should be of some value.

The entire network bought at my nearby Computer City, cost 
around $180, _not_ on sale.  This was for two PCI NE2000-clone
cards, a 5-port hub, and two CAT5 cables.  

The probe will probably recognize your network boards as ``ed2''
This was the case both on my P90 and 6x86 systems.


On my P90 dmesg reports:

 ed2 <NE2000 PCI Ethernet (ProLAN)> rev 0 int a irq 10 on pci0:13
 ed2: address 00:20:78:14:25:03, type NE2000 (16 bit)


My centeral computer, tao, is linked to the net via ppp.  My
new 6x86 box, sage, was what I wanted to link to tao.

--Note: Take Greg Lehey's advice to heart, and try your network
	set-up by typing if the `ifconfig' and `route' commands.
	To save keystrokes, you can exec a shell script on either
	machine.


  ifconfig ed2 inet 10.0.0.1 netmask 255.255.255.0       # tao
  ifconfig ed2 inet 10.0.0.2 netmask 255.255.255.0       # sage

In both systems ::
 /etc/hosts:
 10.0.0.1 tao.whatever.com tao
 10.0.0.2 sage.whatever.com sage

In both systems::
 /etc/rc.conf:
 network_interfaces="lo0 ed2"    # List of network interfaces


## On tao, in /etc/rc.conf
  ifconfig ed2 inet 10.0.0.1 netmask 255.255.255.0   # tao
#
# if you need this additional routing information, add:
#
static_routes="net"
route_net="-net 10.0.0.1 10.0.0.2"



## On sage, in /etc/rc.conf
 ifconfig ed2 inet 10.0.0.2 netmask 255.255.255.0  # sage
route add -net 10.0.0.2 10.0.0.1

The last line on my 6x86 platform is necessary because I have no
router; no hardware that understands how the two systems talk to
each other.  

Thanks gratefully acknowledged to Greg Lehey, Doug White, and 
several others in months gone by.
