We have, in our building, both an ethernet and some Macintoshes. We also have a LaserWriter that everyone would like to use. The LaserWriter is presently connected to a 3B2, and the 3B2 is connected to the ethernet. Is there any software, preferably public domain, which will let us use the LaserWriter transparently from the Macs? We would like to just "point and click" from Word and have our jobs spool to the 3B2 and thence to the LaserWriter. Dan Lamet lamet@sapphire.idbsu.edu

This is probably a stupid question, but here it goes... Do Macs connected to Ethernet have a physical address (not the number that AppleTalk assigns at StartUp) associated with them that can be monitored by and IBM running on Ethernet??? We are running EtherTalk 2.0. The IBMS are connected to Novell Servers. Thanks for any help! -- Timothy A.

For example, Apple's Ethernet card manufactured by 3COM, each have a unique 12 hex digit physical Ethernet address beginning with 3COM's vendor code of 02608C (from memory, I think). > that can be monitored by and IBM running on Ethernet??? > > We are running EtherTalk 2.0. The IBMS are connected to Novell Servers. Well every 802.3 ethernet packet (e.g. EtherTalk 2.0) packet from the Mac will start out with its source Ethernet address set to the Mac's. If the IBM and the Mac can see each other at the Link layer (e.g. no routers between them), the packets that reach the IBM will still have the Mac's Ethernet source address. (If they do pass through a router, or a PC emulating a router, the Mac packet reaching your IBM will have the IBM-side-of-the-router's Ethernet address as it's source Ethernet address.) From there, it's up to the software running on the IBM, as to whether these Ethern et addresses are monitored. Ben Schmidt Bell-Northern Research, Ltd. Ph: (613) 763-3906 Information P.O.
