Re: [Slightly OT] Router advice

Hello, I'm considering throwing away my old 56k and switching to DSL, and I would like to have a UNIX machine set up as a router for my mini-LAN. I've got an old LC475 which has several pros (quiet, very low power consumption, quite stable with NetBSD-softfloat), but one big problem: it can have (and has) only one network card. I know that what I want to accomplish is possible using interface aliases, You don't need aliases or anything - I did exactly this for ages with a little Sun ( running Solaris though ) with only one network interface, the DSL modem plugged into the switch - runs without problems, and even 2x DSL traffic doesn't come anywhere near saturating a 10MBit network. Although - if you have fast DSL ( like 2MBit or more ) the Mac could become a bottleneck - last time I checked they maxed out at ~400-500kB/s. If you use excessive filtering it will be a lot less - my Sun ( 110MHz MicroSPARC II ) ran at ~30% CPU with full DSL load ( I had 768/128kBit ) - I doubt the 68040 will manage more than that at all, but that was Solaris, not NetBSD and it did some logging so your mileage will (greatly) vary. It's a common misconception that you need a separate ethernet interface for DSL - it's nice to have but by no means necessary. Your box will create a ppp interface for it, the rest will just continue working. but my question is, are there any serious drawbacks in doing that? I remember having read somewhere that having a router with only one network interface is not secure -- is that true? Depends - how much do you trust the rest of your own network? And of course you can filter things - the DSL stuff will go through ppp0 or something like that on the router box, no matter which ethernet interface it uses to talk to the modem. Since the traffic between the modem and the router is only pppoe there isn't any harm in piping it through your switch. have fun Michael

You'll want to read between the lines and use a large eraser on the fud in these pages, but they might prove useful. ("Look in folder X for icon Y? Yeesh.) http://www.dslreports.com/ http://www.dslreports.com/faq/faq Also, atmforum.org will be goodcyget?

Re: explain gcc and where do I get it

thank you to all of you who helped me with my first basic questions. Now, what is the gcc compiler and where do I get it ? I would want to run it on a mac OS X (Dual processor G4 ) machine. gcc compiles your source code so that the OS can understand what to do with it. The best thing to do is to get the Mac OS X Developer Tools cd and install it. It should have come with the OS when you bought it. You *did* buy it, didn't you? There is tons of stuff from the GNU people at gnuosx.org . Apple also has a pretty good selection of free stuff available at http://macosx,com/downloads. Can I cross compile from mac os X to the mac 68030 machine (Macintosh performa 460) Yes. How would I configure everything.... ? The question you ask is way too broad. RTFM and, if you have questions based on something you have done, come back and ask specific questions. jeff -- Jeffrey E.
