I've gotten a little help from this list, however I'm still not
SLIP'ing. Anybody else care to help? Please.....I need this for a
Villanova Graduate School project.
Here is what I did.
On the Linux SLIP Server (192.9.202.9) using COM1:
1) Commented out the getty line in /etc/inittab for ttyS0
2) Commented out Ethernet stuff in /etc/rc.d/rc.inet1
3) Rebooted to make the above take effect.
4) Logged in as root and typed:
slattach -s 9600 -p slip /dev/ttyS0
ifconfig sl0 192.9.202.9 pointopoint 192.9.202.8 up
route add default sl0
5) ping localhost -> works OK
On the Linux client (192.9.202.8) using COM3:
1) Logged in as root and typed:
slattach -s 9600 -p slip /dev/ttyS2
ifconfig sl0 192.9.202.8 pointopoint 192.9.202.9 up
route add default sl0
2) ping localhost -> works OK
If I do a 'ps' on both systems it shows slattach running on the
appropriate tty.
On the Linux client (192.9.202.8) I type:
ping 192.9.202.9
All I get is the starting banner message then 'ping' hangs until I
hit a ^C which then reports 100% data loss.
My null modem cable should be fine. I have used it with "LapLink" (a
PC file tranfer program). I also logged in to the Server (when there
was a getty running on it) from Microsoft Windows Terminal Emulator on
the client side. I did have a problem using other VT100 terminal
emulators (Kermit and PC-VT) which transmitted to the Server OK but no
login/password prompts where displayed.
QUESTIONS:
1) Any idea how to debug my slip problems?
I tried the -d option for slattach but it only printed out the initial
communication settings.
2) If I run a serial data analyzer, what should I see from ping?
(Anybody have the 'ping' source code handy?)
3) Do I run slattach on the Server? The Network Administrator's Guide (NAG)
only mentions to run it on the client.
Thanks!
