In-Reply-To: <19980116102821.09261@vmunix.com> Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk I have four fxp's in a Dell Dimension P100t (well, P75t, but I had this extra processor...) and had to go through the manual process of adding each card in separately, recording the Ethernet address, and checking FreeBSD's detection/numbering of the devices by the Ethernet addresses. It turned out that there wasn't a simple ordering of the devices. If the top of the screen corresponds to the rear of the computer, looking from above, I ended up with: e ffff p xxxx 0 pppp 3012 I suppose that maybe fxp3 is out of order because it's a shared slot or something. I don't know much about how that works. But it seems reasonable to assume that this could vary by PCI chipset, and so it's not safe to assume any particular ordering; one could really mess up one's static routing if one assumed wrongly. But you already know from your existing setup what the Ethernet addr of your existing fxp is, so when you change de to fxp, you will know whether you need to adjust your rc.conf. It's a lot easier with one addition! A bug in my MUA causes news.announce.newusers font to be sent to beneficiaries and senders of UCE/SPAM. @ mcs.net Wishes are like dishes.
