SLIP connection to ANNEX.MATH.UTAH.EDU via MS-DOS kermit and SLIP8250. PPP connection to ANNEX.MATH.UTAH.EDU via Win3.1+Winsock and Netscape. Last edit: Sept 24, 1996 ============================SLIP VIA KERMIT=========================== See below (line 190) for PPP via Netscape and Winsock under Windows 3.1. ====================================================================== Hardware required: PC with 2mb memory, 80286 or better. Infotel 14400 modem or equivalent. Software: MS-DOS kermit, version 3.14 or later slip8250.com (provided with MS-DOS kermit 3.14) DOS 5.0 or greater. ====================================================================== Kermit and slip8250.com are available at site kermit.columbia.edu via anonymous ftp. Free. Get it from kermit/archives/msvibm.zip (apr 95). The WWW access is from URL http://www.cc.columbia.edu/kermit/ After clicking on kermit, look for MS-DOS kermit, ftp access. It will be downloaded to disk automatically (768k). This includes slip8250.com. A minimal working set for PC kermit is kermit.exe, kermit.ini, kermit.bat, slpi8250.com, kermit.hlp. The rest can be trashed. Locally, the kermit distibution is mirrored (Apr 1995) at FTP site ftp://ftp.math.utah.edu/pub/ibmpc/kermit/ in file "msvibm.zip" ====================================================================== To make a SLIP (Serial Line IP) connection to the math ANNEX, follow these steps, valid for a setup with bootp parameters and nameserver services: 1. Start kermit. Use the same settings that work for a normal modem connection to the ANNEX terminal server. Normal connection is 14400 baud or less. 2. At the kermit prompt: ==> SET FLOW RTS/CTS or SET FLOW NONE ==> CONNECT ==> ATDT5818105 ==> username ==> password WAIT FOR THE ANNEX PROMPT. THEN ==> slip WAIT FOR TWO ADDRESSES TO APPEAR. USUALLY, GET 128.110.198.130 FOR ANNEX and 128.110.198.135 FOR MY IP ADDRESS ON THE PC. IGNORE THESE ADDRESSES! 3. Escape back to the MS-Kermit prompt and EXIT from MS-DOS Kermit. The connection is left open. ==> alt-X ==> EXIT 4. Start the SLIP8250 driver at the MSDOS prompt: ==> slip8250 0x60 -h slip 4 0x3f8 14400 NOTE: This applies to DOS only. If you are using Windows 3.1 or Win95, then read the Netscape document and in particular remarks about Winsock, which replaces slip8250.com in the windows environment. See the NetScape notes below. 5. Start MS-DOS Kermit again. ==> kermit ==> set speed 14400 ==> set tcp primary 128.110.198.2 ==> set tcp gateway 128.110.198.126 ==> set tcp subnet 255.255.255.0 ==> set tcp/ip address bootp ==> set port tcp solitude.math.utah.edu ==> connect ==> username ==> password ===================================================================== BARE BONES CONNECTION -- FOR TESTING ===================================================================== To make a SLIP (Serial Line IP) connection to the math ANNEX, follow these steps, valid for a bare-bones setup without bootp parameters or nameserver services: 1. Start kermit. Use the same settings that work for a normal modem connection to the ANNEX terminal server. ==> kermit 2. At the kermit prompt: ==> SET FLOW RTS/CTS or SET FLOW NONE ==> CONNECT ==> ATDT5818105 ==> username ==> password WAIT FOR THE ANNEX PROMPT. THEN ==> slip WAIT FOR TWO ADDRESSES TO APPEAR. USUALLY, GET 128.110.198.130 FOR ANNEX and 128.110.198.135 FOR MY IP ADDRESS ON THE PC. WARNING: 128.110.198.135 could be 128.110.198.134 or 128.110.198.136! The address 128.110.198.130 is useless, it is the address of annex.math.utah.edu, not something you can log in on. 3. Escape back to the MS-Kermit prompt and EXIT from MS-DOS Kermit. The connection is left open. ==> alt-X ==> exit 4. Start the SLIP8250 driver at the MSDOS prompt: ==> slip8250 0x60 -h slip 4 0x3f8 14400 NOTE: This applies to DOS only. If you are using Windows 3.1 or Win95, then read the Netscape document and in particular remarks about Winsock, which replaces slip8250.com in the windows environment. See the NetScape notes below. 5. Start MS-DOS Kermit again. ==> SET TCP ADDRESS 128.110.198.135 [PC address given by annex display] ==> SET PORT TCP 128.110.198.33 [solitude.math.utah.edu] ==> CONNECT ==> username ==> password ===================================================================== DOSLYNX connection via SLIP ===================================================================== The application DOSLYNX is a LYNX Web Reader for WWW produced in Kansas, especially for the DOS interface. It seems to require 4mb memory and DOS 5.0 or better to run. Also, VGA is recommended and a fast modem, 14400 or better. Help is available: lynx-help@ukanaix.cc.ukans.edu Advantages: Works on most any DOS machine with minimum video and memory. Does all file loads to the local disk for speedy navigation on the WWW. Downloads of files are seamless to the local disk. Go anywhere on the internet with minimum effort. Uses the mouse on the PC for navigation and the usual PC user interface standards. No unix to learn. Has an internal GIF reader/display for viewing images which incidentally downloads the GIF file to disk. Obtaining DosLynx DosLynx v0.8a is available via binary anonymous FTP at ftp2.cc.ukans.edu in the pub/WWW/DosLynx directory. DosLynx version 0.8 alpha will be the file named DLX0_8A.EXE which is a self-extracting archive. URL notation is ftp://ftp2.cc.ukans.edu/pub/WWW/DosLynx/DLX0_8A.EXE URL notation for the directory is ftp://ftp2.cc.ukans.edu/pub/WWW/DosLynx/ Installing DOSLYNX Make a subdirectory c:\doslynx. Put the archive DLX0_8A.EXE there and run it. That deposits the files. You should create a new "index.htm" and edit the configuration file "doslynx.cfg" (details below). SLIP configuration for DOSLYNX ==> cd \doslynx connect to hard disk directory ==> edit index.htm make a new home page with these contents: DosLynx

Then: ==> cd \doslynx ==> doslynx [to exit use alt-X, ESC exits a bad URL load] ================PPP VIA Windows 3.1, WINSOCK and NETSCAPE=============== Similar setup works for SLIP, which is sometimes required, with certain hardware and software combinations (we don't know why). ======================================================================== PPP Connection to annex.math.utah.edu Using Trumpet WinSock driver under Windows 3.1 Testing with News, Netscape, Ping, Ftp, Telnet. ======================================================================== Hardware and software: 80386 or better, 2mb memory, hard disk with 6mb free Windows 3.1 Trumpet Winsock software package (PPP driver) Or, Cisco system's 'connect' software (SLIP, PPP) Netscape or Ping software, for testing. ======================================================================== WHERE TO GET WINSOCK+NETSCAPE SOFTWARE. Get the net software from Steve's Internet Dialkit, 2 disk set, at http://www.micro.cc.utah.edu/ The usual command to get the files: lynx http://www.micro.cc.utah.edu/win16/internet/16kit.html ======================================================================== Editing the INI files 1995 versions TRUMPWSK.INI ip=0.0.0.0 netmask=255.255.255.255 gateway=128.110.198.126 (math gateway) dns=128.110.198.2 (math name server) domain=math.utah.edu (math domain default) slip-port=1 (for com1; use 2 for com2) slip-baudrate=57600 (for 14400 or 28800 modem connection) ppp-enabled=1 (enable PPP connection) WINVN.INI NNTPHost=news.math.utah.edu (news server) NNTPService=mail.math.utah.edu (mail account site) NETSCAPE.INI Home Page=http://www.math.utah.edu/ NNTP_Server=news.math.utah.edu SMTP_Server=localhost POP_Server=pop.math.utah.edu Note: There is no hope that any of the windows programs will work unless the INI files have been edited. ======================================================================== WINSOCK INITIALIZATION FOR MATH ANNEX (OLDKIT 1995 Version) Run windows 3.1 Run Trumpet Winsock Open DIALLER menu Select manual login Enter AT ATDT5818105 (math number) LOGIN (your login user name) PASSWORD (your password) ppp (after annex lets you in, type "ppp") ESC (press ESC key) Switch to Program Manager in Windows 3.1 Run PING or NETSCAPE to test. ======================================================================== CISCO CONNECT INITIALIZATION FOR MATH ANNEX (NEWKIT 1996 Version) Run windows 3.1 Run Cisco's CONNECT software Open CONNECT menu Select interactive login Enter AT ATDT5818105 (math number) LOGIN (your login user name) PASSWORD (your password) ppp (after annex lets you in, type "ppp") ctrl-G (press CTRL key and G) Switch to Program Manager in Windows 3.1 Run PING or NETSCAPE to test. ======================================================================== NETSCAPE OPERATION It won't work unless Trumpet Winsock has been initialized and Winsock is still running with PPP enabled. A common mistake is to switch out of Winsock without hitting the ESC key (which enables PPP). The script files can automate this once you get it working. The site at the top of the screen should be http://www.math.utah.edu/ The trailing slash is necessary. If you don't have one, then add it into the INI file called NETSCAPE.INI. For testing, add it in the netscape application and hit return to load the new URL. This works also for any other URL, eg, http://www.yahoo.com/ ======================================================================== KILLING THE PPP CONNECTION Don't depend on software like Winsock to kill the modem connection. It probably won't kill it. Instead, cycle the power on the modem. Doing this will let you exit from Winsock, which refuses to let you out when a PPP connection has been made. If you are lucky enough to have a "bye.cmd" on the DIALLER menu in Winsock, then use that command to shut down the modem (before exit from Winsock). Hint: it does not hurt to type ESC in Winsock. Doing that enables menu items on the DIALLER menu. Note: PPP means "PC-to-PC Protocol", which is SLIP plus another software layer that makes connection to remote sites like annex.math.utah.edu much more convenient. The extra software layer resolves automatically the IP address that is dynamically assigned by annex.math.utah.edu (different on each login). This gets windows users out of the business of typing IP numbers. ======================================================================== NETSCAPE WON't RUN It is a common complaint that clicking on netscape has no effect - it won't run. The trouble is that Winsock is hung up trying to make a PPP connection. Maybe something simple is wrong, like the modem is off. But it could be more serious, such as not editing the INI files as suggested above. Please note that the editing is required **before** running Winsock. You can exit Winsock, then edit the INI files, and run Winsock again with the new settings. Winsock is successful when it publishes the success of the PPP connection. If this doesn't happen, then it didn't work. Connect is successful if it prints something after "authenticating..". ======================================================================== COMPUTER CENTER SLIP CONNECTION Connections to the computer center Cisco server have different instructions. Don't generalize what is written here to that setting. Use Steve's Internet Dialkit setup for that configuration. It comes out of the box with the right parameters set. Especially, study the files with extension CMD in the WINSOCK directory, because they control the interface to the CISCO server and your computer. In particular, setting PPP enabled will cause the scripts to fail. So if you have fooled around with INI files, then it may break the possibility of connection to the CISCO server. The essentials for the CISCO server: username password "slip default" This will allow a connection via SLIP, provided the Winsock INI file is set up for SLIP. With the 1996 "connect" software, the slip address printed on the screen has to be transferred, in order for applications like Netscape to work. Note: No one has made PPP work with WINSOCK (1995), so don't waste your time on the idea. Nor with Cisco CONNECT (1996). There is something strange with the CISCO server which causes some modems to drop the connection within a few seconds. ========================================================================
