Setting up PLIP(Parallel Line Internet Protocal) on Small Linux - Steven G.

I followed the instructions in the June 1998 issue of Linux Journal. Thanks to Loris Renggli.

This is a network connection through the parallel port. Once the PLIP is up and running,
you will be able to use telnet, ftp, rcp, or lynx.


special printer cable - "laplink cable"

two computers - root access on both
modern printer ports on both machines
tcp/ip utilities:
general utilities
plip compiled into the Linux kernel, or
plip functionality thru modules- modprobe, plip.o

My case:

1. Pentium 133 - 64 meg running SuSE 5.1 -standalone - kernel 2.0.33
2. 386sx 50 mhz - 4 meg running Small Linux 0.3.0 - standalone - kernel 1.2.11

My steps:

1. setup etc files on both computers
    hosts  - on Pentium computer (sag) localhost sag baby
    hosts - on 386 computer locahost baby sag

2. setup plip startup script files  on Pentium computer (sag) - plip as modules
                /sbin/modprobe plip1
                /sbin/ifconfig lo up
                /sbin/ifconfig plip1 sag pointopoint baby up
                /sbin/route add sag  dev lo
                /sbin/route add baby dev plip1 on 386 computer (baby) - plip compiled in
                 /sbin/ifconfig lo up
                /sbin/ifconfig plip1 baby pointopoint sag up
                /sbin/route add baby  dev lo
                /sbin/route add sag dev plip1
 3. setup cable between the two computer
        both my machines have two parallel ports
        port # 1 is 0x378  irq 7  on both

4. run on both machines

5. test network settings and connection
    route should print out localhost and other machine
    ifconfig should printout lo and plip1 address
    then using ping should get response from remote computer

6. have deamons running or available on sag

7. enjoy it!
    telnet should log in to remote
    ftp can be used to transfer files

8. setup NFS for mouting network drives
