This follow-up message is from: Bob Nirenberg, I finally managed to get my Mac at home to remotely control my PC running NT 3.51 at work via a dialup connection. Once set up it works quite well, and it's great for telecommuting without investing in large amounts of hardware. There are also some deals on the software out there. I got a few suggestions from the lists, but in the end the only way to work it out was via tech support from Farallon plus careful reading of Apple's docs on OT/PPP. The connection mechanism applies equally well for telnet, ftp, web browsers, etc, which work over TCP. Here's how to do it: 1) On the NT side, you must use Timbuktu Pro for Networks 1.4 or later, and NT/RAS. Do not use DHCP to assign IP addresses to the incoming call as Microsoft has added proprietary extensions to DHCP which are non-standard and are not supported by the Apple software. Rather, set up a pool of two statically-defined IP addresses on the NT side. When the incoming call is made, the RAS PPP server will assign the second address to the Mac, and the first to the modem port of the PC. Set up a userid for the incoming call using the Administrative Tool "User Manager". This userid and password will be used by PPP on the Mac side for the connection. In Remote Access Admin, make sure you check the box granting permission to dial in for this userid. In Remote Access make sure you set the network protocol to PPP, turn on TCP/IP and turn off NetBEUI and IPX, for this user. The other settings are up to you. Go into the Network Control Panel and choose Remote Access Service. Press configure... and choose your modem. Press Network... and then check off PPP, TCP/IP (and not NetBEUI or IPX) in the dialout settings. In Network settings again check off only TCP/IP and allow any encryption settings. Press TCP/IP configure... and check static pool, and enter your two IP addresses. That should finish the NT side. 2) On the Mac side, you must use Timbuktu Pro 3.2 or latter, and you can use either FreePPP2.5v2 or OT/PPP 1.0. I prefer the latter. In any event, use the authentication mechanism (in PPP control panel options) which does not set up a terminal window. Set up the DNS server address as well (in the TCP/IP control panel options) if you will want to be able to go outside the NT machine onto the network. In the PPP control panel make sure you use the userid and password which you set up previously on the NT side with User Manager. You will still need to log on to the NT domain (as if you were in front of the NT machine) after the dialup connection is made if you are using Timbuktu. 3) Once you make the dialup connection (using the connect button in the PPP control panel), you are on the network. If you have configured Timbuktu on both ends you can then start up Timbuktu on the Mac, to control the NT machine. Make sure that the IP address you give to Timbuktu is the lower of the two addresses in the static pool, not the primary IP address of the NT machine. Once you have done this a few times, you can check the box in the TCP/IP control panel which allows TCP/IP to start up when requested by an application. This will preclude the need to manually connect via the PPP control panel when you want to start a session. Simply start your application, and the connection will be made. OT/PPP and OT/TCP/IP allow you to save multiple configurations, so if you need to make dialup connections via different methods, look at the Configurations item in the File menu in each. There are also shareware scripting additions which allow you to make double-clickable AppleScript applets to switch both configurations without going into the control panels. I've tried Cyberdog, NCSA Telnet, and Mosaic over this PPP link and they all work just fine. I suspect the other Web/Net tools will work as well. I have not yet got my NT machine to remotely control my Mac over the phone. Apparently you need a PPP server on the Mac to do this, and I don't currently have ARA 3.0, which according to Farallon works. The setup should be similar. Thanks to all who volunteered their assistance, and particularly to one tech support person (Byron) at Farallon who was quite knowledgeable and persistent.
