- I've been meaning to do this RSN, & found this info via veronica
- it looks fairly detailed & comprehensive, hope it helps.

- Subject: How to configure a Sun as a SLIP server
-
-
- This document is directed at Unix workstation administrators/programmers
- who may want to set up a SLIP service for Mac/PC/Unix dialup users.
-
-
-
- SLIP is Serial Line IP. A SLIP server enables a home computer (Mac, PC, or
- Unix) to connect thru telephone dialup to the Internet. For Macintoshes,
- there are now 2 or 3 vendors selling a SLIP module to work with Apple's
- MacTCP software. There are also other, and probably better, ways to
- get a SLIP service than is described here. Some terminal server hardware
- includes SLIP support. Some commercial venders sell dialup IP service.
-
- This describes my results recently from two days of hassles w/ free slipware
- for Sun Sparcstation (sun4c model using SunOS 4.1.1). Your mileage will vary
- depending on the Unix workstation you wish to set up as SLIP server. The Mac
- side is much easier.
-
- Suppose your organization's class B network number is 139.123, and you are
- subnetting with a class C-sized network mask of 0xffffff00. Your
- departmental LAN is subnet 139.123.4.0, with an ethernetted Unix workstation
- called SunGod (139.123.4.1) among the other workstations on this subnet. A
- modem is attached to one of SunGod's serial ports. A Macintosh named MacHome
- wishes to connect to the network thru SLIP.
-
- Steps for this, using freely available slip software for Suns are:
-
- 1) plug a modem into a serial port on your Sun.
-
- 2) build in the SLIP pseudodevice into the Sun Unix kernel. Use
- either slipware 4.0, cslip (compressed slip) based on 4.0 or
- slipware 4.1 [see ftp refs below]. Unix kernel setup is only
- for knowledgeable Unix programmers/administrators.
-
- 3) compile and install the SLIP driver program(s). This may be
- "sliplogin", which also uses the /etc/hosts.slip table and
- which seems most convenient for multiple users, and which leaves
- your Sun serial port available for regular dialins at other times.
- Or "slattach" which attaches a serial port on the Sun as a
- semi-permanent SLIP port.
-
- 4) Assign MacHome an IP address, 139.123.4.99 for example,
- in Sungod's /etc/hosts table:
-
- 139.123.4.99 machome.my.domain.edu
-
- If using sliplogin, construct /etc/hosts.slip table:
- # /etc/hosts.slip
- # notes: local-address is the SLIP server (SunGod)
- # remote-address is the dialup computer (MacHome)
- #username mode local-address remote-address netmask
- myaccount normal 139.123.4.1 139.123.4.99 225.225.225.0
-
-
- 5) Link the remote IP host MacHome to SunGod's ethernet address. This
- rather important step is not discussed in the slipware documents. Use
- command like "arp -s RemoteIPaddress LocalEthernetAddress pub".
- See arp manpage.
-
- Interactively as root on Sungod for testing and/or in Sungod's
- /etc/rc.local add this line:
-
- arp -s machome `ifconfig le0 | sed -n "/ether/s/ether//gp"` pub
-
- 6) On MacHome, if for instance Versaterm SLIP driver is used with MacTCP,
- configure Versaterm AdminSlip properly. If using cslip on Sungod, must
- check the compressed slip option on Mac, otherwise uncheck this. Insert
- the IP address of MacHome, the net mask (as above) for your subnet setup,
- and a gateway IP number, as used for other computers on this subnet.
-
- 7) dial up from MacHome to SunGod's modem using your Mac Slip program (e.g.,
- Versaterm AdminSLIP). Log in w/ user and password as if you were logging
- on for interactive session. If using sliplogin, you can run this kind of
- script at logon (where modem is connected to SunGod's /dev/ttya serial port):
-
- #!/bin/sh
- /usr/bin/mesg n # may not be needed
- stty -tostop # may not be needed
- # sliplogin, called by user, reads /etc/hosts.slip for local:remote nodes
- exec sliplogin < /dev/ttya
-
- 8) Slip should now be working, try running NCSA Telnet (MacTCP), GopherApp,
- Eudora (MacTCP) and other such MacTCP programs.
-
- 9) When session is done, hang up slip line. Modem on SunGod now should be
- free for other users' regular or slip sessions.
-
- Repeat steps (7) to (9) as needed. Don't call me in the morning.

- >From Steve Dorner's recent SLIP for Mac review:
-
- VersaTerm SLIP comes with VersaTerm 4.6.2, which goes for about $90
- mail-order, and includes an FTP server and client, MacTCP, a Telnet
- connection tool, and a time server and client. Educational institutions
- are eligible for a reduced price arrangement. Contact Synergy Software,
- ads in many Mac magazines or via mail order software houses.
-
- MacSLIP is $49.95. Site licenses will be available for a reasonable price.
- Contact macslip@utexas.edu for more information.
-
- InterCon has announced a Mac SLIP module. Contact Help@Intercon.Com
