Helo out there in netland, I am looking for a way to hook my system into an Internet feed in another town. The simplest method would be to hang a modem off of both machines (mine an Amiga 3000UX and the other site a SparcStation 2) and run SLIP, PPP, or dialupip over a regular phone line between us. There are two problems with this, first the LD charges (same area code, different local telcoms) and second the use of a valuable serial port in the back of the SS2. Another method of accessing the SS2 seems to clean up both of these problems, but I am not sure if one of the serial line ip packages would work over it, some have said that it would and others have said that it wouldn't as part of the connection is itself packetized. Here's the set up. Let's say I am in city A and the SS2 is in city B. There is a terminal server in city A that has modems hanging off of it and can connect to the SS2 in city B over a DECnet or TCP-IP connection (I am not sure which). Here's the question, would any of the serial line ip packages (SLIP, PPP, or dialupip) be able to run over this kind of connection ([mybox]-[modem]-[modem]-[terminal server]-[SS2])? Has anybody done this or know if it could be done or not? On a related note, has anyone run one of the SLIP or like packages over a connection facilitated by a pair of 2400 bps V42.bis (4 to 1 compression) modems (I know - SLOW, but they are cheap and what I have available to me right now.) Please respond via e-mail as I can not always read news. I will share any answers either via e-mail or, if volume dictates, I will post a summary.

Well here is the followup I said I would post. It seems that, using a "plain, no frills" terminal server, you are out of luck, however there are terminal servers that do support SLIP (some even support PPP). With these servers, you connect to the server as a regular session and then do the commands to start SLIP (something like "set terminal internet slip enable") and go back and start your SLIP connection without dropping the line. With these servers (Xyplex, Cisco, and some others) you do not even need to continue your SLIP link to a "gateway" machine. The server, in fact, acts like a slow router. Once you are SLIP'd to the terminal server, that is on the desired network, you are connected and _shuldn't_ need to do anything else then set up some nameservers if needed. There has been concern expressed about running a SLIP connection with a lot of high-density trafic over a terminal server as possibly being detrimental to throughput for other users. My application will be a very low density connection, however. Any more comments or questions are wlcome.

Here's the question, would any of the serial line ip packages (SLIP, PPP, or dialupip) be able to run over this kind of connection ([mybox]-[modem]-[modem]-[terminal server]-[SS2])? A good number of todays terminal servers support SLIP directly. Some even support PPP. This would solve your problem more convieniently. Bill Westfield cisco Systems. -------
