A null modem cable and a laplink cable have different connections, as I found out the hard way when I wanted to get PLIP working between two Linux boxes. I did find websites that sell cables and spec the pinout. Regardless of what they call it, if you know the pinout, you're in business.

RE: [Wlug] Xmon / Serial cable

by Evans, Robert

To answer question 2... A search for "null modem cable" on google will give you lots of good hits. For local kernel debug, you might just need to connect: Athlon Mac ground to ground txd to rxd rxd to txd If that is not enough, handshaking might require additional connections. There are variations, but I have had success, in other applications, with this handshaking setup: dtr to cd & dsr cd & dsr to dtr rts to cts cts to rts On a 9-pin connector: 1 = cd 2 = rxd 3 = txd 4 = dtr 5 = ground 6 = dsr 7 = rts 8 = cts 9 = ri You can probably buy a null modem cable at radio shack. It might also be sold as a lap-link serial cable. Be sure that the sex (protruding pins vs. recepticle) of the connector on the cable matches that on the computer you will connect to. Robert N.

Xmon / Serial cable

Folks, I'd like to try my hand at debugging the kernel boot process on a Macintosh PPC. I have a couple of silly questions, though. 1) Can I debug a Mac from an x86 box using Xmon? 2) I need a null modem cable to connect my Athlon and my Mac. Any thoughts as to where I could buy such a beast, or how to wire one up from parts obtained from Radio Shack? Thanks, Skip

Usually the software has a "burn from image" or "burn from master" option that lets you select a file and burn that to a cd. -- Randomly Generated Tagline: "The Beatles used more hair products then Jesus." - Rusty McGee

You need to setup virtual hosting. I don't actually use the RH default sendmail (I roll my own), but I believe the default one already has virtual hosting enabled. What you'd need to do is: 1) Edit /etc/mail/local-host-names and add "host1.com" and "host2.com" (this should already be done actually.) 2) Edit /etc/mail/virtusertable and add: @host1.com error:nouser User unknown sales(a)host1.com user1 @host2.com error:nouser User unknown sales(a)host2.com user2 3) cd /etc/mail && make Theoretically, that should be all you need to do. You can test via "sendmail -bv". For instance: "sendmail -bv 'theo(a)vandinter.org'" returns "theo(a)vandinter.org... deliverable: mailer local, user felicity" for me. You'll need to do more work if virtusertable isn't already configured for your sendmail. There's a lot of information at http://www.sendmail.org/virtual-hosting.html. -- Randomly Generated Tagline: "This car began to rust while it was still in the showroom." - Unknown about the Dodge Aspen/ Plymouth Volare

Burning ISO's
