The SLIP connection to Apache Point has been up and running for a while now. I have been using it from home quite successfully. The link is a bit slow still due to other network problems at APO which I am still looking into. For those of you who know what you are doing the relevant information is: phone (505)437-6149 modem: up to V.34 with MNP5 address: 192.41.211.58 (server will respond with the address so you can use server addressing) subnetmask: 255.255.255.240 nameserver: 192.41.211.40 I have a short write up on setting up Versaterm and Interslip drivers on the Macintosh for those who need it. It is enclosed at the end of this message. Jim Fowler ------------------------------------------------------------------------- Think! It's good practice for when the computer is down. James R.

Fowler 5 July 1995 (505)437-6822 jrf@galileo.apo.nmsu.edu So, you are sitting at home in your favorite recliner having a beer and you decide you want to go netsurfing. Your Macintosh is just sitting there doing nothing except allowing fish or toasters to swim across the screen. You figure there must be some way to get your fish to swim on the Internet rather than your wading pool. Well there is; all you need is a telephone line and a SLIP connection to get you into the water. In this write up I am assuming the following configuration: A Macintosh of some sort, the faster the better. (If you have PowerPC Mac however some of these things change.) Mac OS 7.1.1 or 7.5 (preferred) MacTCP 2.0.4 or 2.0.6 (preferred) A slip driver. The only ones I know of at this time are: Interslip: available for anonymous ftp at ftp.intercon.com as /InterCon/sales/Mac/Demo_Software/InterSLIPInstaller1.0.1.hqx. Remark hangs up on startup but Telnet, FTP, and Mosaic work properly. I have had a number of reports that this version is more buggy than the VersaSLIP driver. VersaSLIP: Part of the Versatilies package from Synergy Software. This package costs real money but only $50 with educational discounts. Remark, Telnet, FTP, and Mosaic all work with it. A modem; either V.42 or V.34 with MNP5 error correcting. The V.34 protocol supports faster connections. A telephone line. Call your local phone company. I can't help you with this one. Quick Setup: If you already have things configured then the following steps will get you connected. 1. Reconfigure MacTCP and reboot if MacTCP is not already configured. 2. Open the appropriate administrative panel; either InterSLIP Setup or Versa AdminSLIP. 3. Select the appropriate SLIP configuration. 4. Click the Connect button. 5. Hopefully your connection will be made. 6. You can close the admin panel or leave it in the background. Configuration. Before you actually jump in the water you will need to configure the modem and the SLIP drivers. The modem needs to be setup to pass binary data through while the SLIP drivers need to be told who to call and how to negotiate the session. Configuring the Modem. In order to do SLIP a modem needs to be set up to pass binary data and to do hardware flow control. This is different from the usual factory default settings which expect to use software (Xon/Xoff) flow control and to only pass ascii characters. I assume that your modem uses a Hayes compatible command set. Note however, that many modem manufacturers add or change features of the command set. Your modem may be different than the one I am use to. If you have problems please give me a call. Set guard off ATS2=128 AT&G0 Set hardware flow control ATS58=2 Turn off modem responses ATQ0 (not critical) Use autobaud on RS232 ATS51=252 (modem dependent) Configuring the SLIP drivers. InterSLIP: Install InterSLIP in accordance with the documentation supplied. Follow the directions for configuring InterSLIP. Note that there appears to be a conflict if both InterSLIP and VersaSLIP are both installed. To connect to Apache Point you will need to set the following parameters. Serial Port: modem (or printer; your preference) Baud Rate: 38400 (if you modem supports it otherwise lower.) Databits: 8 Stop Bits: 1 Parity: none Hardware Handshaking: YES Speaker on while dialing: YES (unless you hate listening to modem noise. I like to here the session being setup.) Dial Script: Hayes Compatible Dial: Tone (or pulse; depends on your phone line.) Phone number 15054376149 Modem Init: What ever you like. You can have your modem switch between a binary SLIP connection and an ASCII terminal connection by resetting the modem every time you make a connection. Call me or your local guru if you want more help. Gateway: Direct Connection ( I don't have any login or password set.) IP address: 192.41.211.58 Nameserver: 192.41.211.40 RFC 1144 Compression: NO (not supported yet) MTU Size: 1500 VersaSLIP: Install VersaSLIP in accordance with the documentation supplied. Follow the directions for configuring VersaSLIP. Note that there appears to be a conflict if both InterSLIP and VersaSLIP are both installed. To connect to Apache Point you will need to set the following parameters. Configuration Dialog: Label: what ever you like. Phone Number: 15054376149 Baud Rate: 38400 (or the highest speed your modem will support) Handshake: RTS & CTS Type: Modem Terminal after Connection: NO (unless you need to debug the connection) IP address: supplied by MacTCP, should be 192.41.211.58 Net Mask: 255.255.255.240 Gateway: 192.41.211.33 Bits/Parity: 8 bits/None Idle Timeout: None IP MTU: 1500 CSLIP: YES Configuring MacTCP. Before make the actual phone call you need to set up MacTCP with the control panel. This sets the higher level network parameters. If you are calling Apache Point you need to set the following options: Select the InterSLIP or VersaSLIP driver. Select MORE Set the Obtain Address to Server Set the Gateway address to 192.41.211.33 Set the Subnet Mask to 255.255.255.240 Set the Domain Name Server to 192.41.211.40 ------------------------------------------------------------------------------ APO APO APO APO APO Apache Point Observatory 3.5m APO APO APO APO APO This is message 2 in the apo35-computers archive.
