I've already indicated that the fxp card was not in full duplex,
and I've since corrected that. Now I don't see any errors, drops or
collisions on the workstation, but on the server I see:
Name Mtu Network Ipkts Ierrs Opkts Oerrs Coll Drop
xl0 1500 <Link> 72374833 29770 73159292 0 171 0
I'm perfectly willing to chalk this up to the 3com card being a piece of
crap, but isn't it a little odd?

Another reason why I decided to stick with the x-over cable. Now
that I'm looking at adding another machine to my network though, I'm
thinking of getting a switch. I found a pretty good deal on one from
Allied Telesyn, is that a reputable company? The link is:

8 ports is probably more than I need, although this particular item isn't
significantly more expensive than the 4 port models with similar features,
and I'd rather not go through this all again N time periods from now.
Another alternative I'm considering is just getting more
ethernet cards and making the server/firewall machine more of a
"router," since I have a lot of free slots on that motherboard. That may
be a little grandiose though... A co-worker got an "ETHERFAST CABLE/DSL
ROUTER WITH 4 10/100 SWITCHED PORTS" from linksys,
http://www.us.buy.com/comp/product.asp?Sku=10235958 which looks like a
lot of fun, but it only has 4 ports, and I'm afraid that if I ever get a
laptop I'm going to be out of luck, since I don't think that one is
stackable.
Also, does anyone have a good reference to what features to look
for in a switch? I try to learn a little networking on the side when time
allows, so I'm familiar with basic concepts, but as you may have noticed I
am a little over my head here. :) I do appreciate the help though, and I
feel like I'm definitely learning something.
