I'll get to try it soon. I want to use a redirector and a web server on the same NIC of a single machine, and have them both use the default port (80). So, I'll just add an IP to the setup and tell both squid & apache to listen on a single IP. Thanks, Bill

Enable the option in the kernel, then in addition to the main "eth0" interface, you'll get a bunch of other ones of the form "eth0:0" "eth0:1" etc... if you wanna go ghetto-style, you can just do this: ifconfig eth0:0 xxx.xxx.xxx.xxx and it will bind to the specified address. You can do this for more than just listening. I use it to route messages between two virtual subnets. It's real handy when your ISP gives you three real IPs, and you want to masq the rest without creating multiple physical networks. -Chuck

Multiple IPs on one NIC

by Bill Mills-Curran

I know it's possible to assign multiple IPs (at least for listening) to a single ethernet device. I _know_ I should read first and ask questions second, but I'm just _so_ lazy, and there hasn't been much traffic anyway. TIA, Bill

Re: [Wlug] new machine questions

by Gary J. Hanley

The Duron is by far the best price/performance platform right now. I just built a Duron 850 with an Asus A7V133 MB, 256MB SDRAM, 30 GB HD, ATI Radeon 64MB DDR, Plextor CD-RW 12-10-40, etc. for less than 800 sans monitor which I already own. You can save more if you buy the lower-end components. I also overclocked the font-side bus from 100MHz to 133MHz which really allows more bang for your buck. To do this you have to "unlock" the AMD CPU multiplier which is not hard, but you need some conductive ink to do this. It's all described here: http://www.anandtech.com/showdoc.html?i=1345 Even if you decide not to OC the FSB the Duron is still the P/P leader, in my steadfast opinion. :-) Currently I suspect that www.newegg.com is the best place to buy hardware on-line. The prices are really competitive and the service (in my case) was first-rate. -- Gary ----- Original Message ----- From: "mike" <mhardy_mail(a)yahoo.com> To: <wlug(a)mail.wlug.org> Sent: Sunday, June 24, 2001 11:31 PM Subject: [Wlug] new machine questions > Howdy all - > > I'd like to replace my computer (P100) with something > newer and significantly faster (but nothing bleeding > edge; I'm looking for good-value speed).

new machine questions

by mike

Howdy all - I'd like to replace my computer (P100) with something newer and significantly faster (but nothing bleeding edge; I'm looking for good-value speed). I'm thinking up to 1GHz (P3?). I want 16/24b color and since I've been out of it awhile I don't know anything about card makers anymore (like what's good, compatible, etc.) or if the std these days is on-board video. I've used Linux for years and want something that will allow me to get/use a scanner (first time; SCSI or USB? recommendations?) and CD-RW (recommendations). I have magazines and documents I want to scan and store on tape or CD. But what's most important is that I be able to generate some sort of index so that I can search the scanned documents (like keywords or text). What do I need for that? Can someone recommend hardware/software for this purpose? I haven't been a 'PC expert' for many years (and don't want to become one again :->) and am therefore no longer up on the latest PC technologies by way of mb, bus speeds, what's a value and what's a waste of money. Can anyone recommend hardware and someone local that sells build to order machines (no brand-names or CompUSA types)? Anything from Worcester to Shrewsbury to Marlboro to Acton to Natick, etc. Does anyone buy machines by mail and have anyone they'd recommend (or who to definitely avoid)? Thanks...

You can see for yourself by looking in /proc/bus/usb/ . What you need to do is find the device that your sandisk is associated with, and mount that.
