Multiport ethernet cards
I'm looking for cards that let me fill a box up with as many ethernet ports as possible. The purpose is to build a router-type machine, so they don't need to be 100mbit interfaces even if that's a plus. The only card I know of that seems to work on Linux is the DFE-570TX (Dlink card with 4 100mbit ports), but I can't find confirmation that it would actually give me 4 eth devices. In short, HELP! :) // Kim Lundgren -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

As it's a PII-350 it can handle a continous load of about 30mbit (without fastroute). However to be able to correctly configure and handle more than 8 interfaces you need to apply some small patches to the kernel and network drivers (there are some constants you need to change etc). If you need to scale beyond 4 cards you have to be careful what motherboard you select, simple because even if they have five or six pci interfaces it's not certain they can handle pci bus mastering interfaces on all. /Roger - Roger Abrahamsson, Senior Sys/Net Admin, Obbit AB Radhusespl.17D, S-90328 Umea, Sweden Phone: (+46)(0)90 133310Fax:(+46)(0)90 133370 - -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

fast router
> 30mbit (without fastroute). However to be able to correctly configure and can fastroute be applied to all (or the majority) of Ethernet cards out there (perhaps I should be asking Mr. Becker this but..), Becker says "chip-specific code for many 8390-based ethernet adaptors", but I have no idea which those are and I'd have no idea how to combine the provided source code (8390.c) that is fastroute with board specific code like he also states. Has anyone seen a howto for fastroute? Have any numbers ever been calculated or run in a test to see what a top of the line intel based PC can crank out in terms of packets/sec? I'm building a router and am going to use tulip based cards as I hear they're good, any comments on what's the best NIC to buy? Has anyone created a clear consise howto on setting up Linux as a highspeed router/firewall? I've yet to find one that outlines some of the more advanced tweaks you can do such as... echo "5" > /proc/sys/net/ipv4/route/gc_interval echo "1" > /proc/sys/net/ipv4/route/gc_min_interval echo "30" > /proc/sys/net/ipv4/route/gc_timeout http://www.linux.com/tuneup/database.phtml/Networking/001525.html or echo 30 > /proc/sys/net/ipv4/tcp_fin_timeout echo 1800 >/proc/sys/net/ipv4/tcp_keepalive_time echo 0 > tcp_window_scaling echo 0 > tcp_sack echo 0 > tcp_timestamps http://www.linux.com/tuneup/database.phtml/Networking/000815.html An O'Rielly book perhaps? I know of the Gibraltar debian based distro, but I'm looking for doc's. Has anyone tried Gibraltar? http://gibraltar.vianova.at/ How many questions can ask in an email before it starts getting annoying? :/ one more! old hardrive space wasting riddle: A pizza is ordered. The delivery boy brings the pizza with a bill for exactly $30.00. 3 guys each give him a $10.00 bill, and he leaves. BUT there was a mix up, the bill was only $25.00, not $30.00. The cashier gives the deliver guy 5 one dollar bills and sends him back He knocks on the door and one of the fellows answers. He explains about a mix up in the bill, and hands the guy three dollars, then departs with his two dollar tip in his pocket. Remember $30-$25=$5 Right. $5-$3=$2 Right. Each of the three guys originally gave $10.00 each. They each got back $1.00 in change. That means they paid $9.00 each, which times three is $27.00. The delivery boy kept $2.00 for a tip. $27.00 plus $2.00 equals $29.00. Where is the other dollar?? Hope this didn't offend anyone, my first post do debian-isp (I think). -- Jason Hammerschmidt - "Sapere Aude" - [EMAIL PROTECTED] MacLaren McCann Interactive - direct 416.643.8560 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Matrox NS-FNIC/4 Multiport ethernet cards
Hi Kim. I can offer you the Matrox NS-FNIC/4 multiport NIC. This card has 4 ports of 10/100 Base Tx each. We have drivers for Linux and they are actually included as part of Kernel 2.2.16. That driver will support 2 cards (8 ports) but the official Linux Maintainer has told us that the new driver he will include in Kernel 2.4 will support more and will also offer port aggregation... The card is based on the Intel 82559ER controller. A very low power consumption, cool running, high performance chip. See: http://www.matrox.com/netweb/products/nsfnic4.htm Please feel free to contact me at the Sales number below or Maya Theodory of Matrox Networks Customer Service.
