- Several days ago I posted this to several newsgroups:
-
-
- I would like to be able to run SLIP between a pc at home and our DECstation
- 5000 at school. I need to dial up to a terminal server and connect to our
- machine over LAT. I have set up the DECtstation end correctly. (I think) But,
- how do I connect to it from the PC? I tired using procomm to dial the modem
- and connct to our machine. Then, I exit procomm without hanging up the line.
- Then, I run the slip packet driver SLIP8250 and the run CUTCP. But, how
- does cutcp know that I am connected to the machine? There must be something
- I am missing out on. What would be the best way to accomplish what I am
- looking for? Your help is greatly needed/appreciated.

- The answer to my question was using the -s qualifier to telbin to
- set it into server mode so it would know it was already connected
- to a slip line. But, there were LOTS of people who sent me mail
- wondering how to set this up. Well, I will attempt to remember all
- of the steps I took. It really isn't bad.
-
- Equipment:
- DECstation 5000/200
- IBM PC clone 386/40
- 2 USRobitics V.32bis modems
- DECserver 200 running LAT
- Software
- CUTCP (Clarkson's version of NCSA) for the IBM
- SLIP8250 packet driver for the IBM
- Procomm for the pc to dial the phone
- slattach and sliphosts on the DECstation
-
- Procedure
- 1. Install CUTCP on PC.
- a. edit config.tel file to be set up for slip (see attached)
- 2. Install slip driver. This was recommended to me a very helpful
- individual. :) SLIP8250 0x60 -h SLIP 3 0x2fd 9600 1500
- this assumes you are using COM2
- 3. Put an entry into the passwd file on the DECstation with a user
- name that is the name of the PC. You need to put slattach in
- place of the normal shell. Like this:
- SDLPC1:No_Way_Man:17033:79:Pc at My house:/usr/new/slattach
- 4. Edit the /etc/sliphosts file to contain a field that defines
- the machine you are connecting (the pc) here is mine:
- sdlpc1 sdlpc1.psych.wright.edu sdl 255.255.255.0 any /dev/tty
- Where: sdlpc1 is the name of the pc and sdl is the DECstation
- 5. I used procomm to dial the terminal server and connected to my
- machine (the DECstation). At the login prompt type sdlpc1 (for me)
- and then the password. On our system the motd came up and then
- it just sat there waiting for slip stuff to come across the tty.
- Then, exit out of procomm without hanging up the line.
- 6. Go to your telnet directory and type telbin -h config.tel -s
- This will set you into server mode and make the SLIP connection.
- (If the above steps went well) Then, you can make a connection
- by hitting ALT-A and choosing the name of the machine you want
- to telnet to.
-
- WARNING: I am VERY new to this so am in no means an expert. There
- others that are. I am just posting my experiences for
- the people with similar setups. There are still other
- things I wan to try like header compression and connecting
- the modem directly to the back of the DECstation instead
- of on the terminal server.
-
- My config.tel for slip:
- This assumes SLIP8250 was run as above
