This is a question for you network administrators. I have a Mac and a Sun. I frequently need to transfer files (big rgb files) between them. Tired of shuffling floppies, I decided to get some kind of Ethernet connection for my Mac so that I can telnet to my Sun workstation and ftp the files. I just got an EtherTalk NB card from Apple. After I installed it, I found out that it would not allow me to use LocalTalk network and Ethernet network at the same time. In order to switch between networks, I have to open the Control Panel, choose the network I want to use, and reboot. I just can't believe Apple could be this stupid! I've seen people using a Mac on the Ethernet while connected to a LocalTalk network at the same time. But I don't know what it takes to have that setup. Could anyone give me some suggestions? Thanks in advance for your help. Please send e-mail to: zhao@portia.stanford.edu David

As an example, if you were using NCSA telnet or TCP/Connect II, you set which net (port) they are using internally not through the control panel. So you leave the control panel alone (on appletalk) and either in the configuration file or on the configuration screen of the TCP/IP package you pick the Enet card. Then you have no problem.

In order to have a multi-homed workstation, you usually need to be running a routing process. For example, if you wanted to, you could run Apple's Internet routing software and have both your Built-in and Ethernet ports passing AppleTalk protocols simultaneously. Of course you'd have to pick one of those ports to be your "home" port, so your mac would know which zone to highlight when you open your Chooser, among other things. :^) > I've seen people using a Mac on the Ethernet while connected > to a LocalTalk network at the same time. But I don't know > what it takes to have that setup. The difference here is that they're using a *different* protocol on each interface. For example, the NETWORK and MACTCP control panel documents work quasi-independently. You can use LocalTalk for your AppleTalk protocols by selecting Built-in from within the NETWORK cdev, and simultaneously use your Ethernet for your TCP/IP protocols by selecting Ethernet from within the MACTCP cdev. Since your using a *different* interface for each protocol, the Mac has one and only one AppleTalk address, that of it's LocalTalk port. And it has one and only one IP address, that of it's Ethernet port. By the way, as far as APPLETALK protocols are concerned, it is not necessary to reboot to switch from LocalTalk and EtherTalk Phase 1 or EtherTalk Phase 2 networks. However if you are using APPLETALK based applications which NBP register themselves at startup via an INIT, these INITs will not be re-executed when you switch networks so that these NBP registered sockets will not appear on the network you've just switched to to until you reboot.
