I am trying, so far unsuccessfully, to connect two linux boxes
with a null modem cable and slip, following the directions in the
NET-3-HOWTO.
One machine, bobspc, is a Micron Pentium-166 that is my primary
computer, while the other, zeos, is an old 486DX-33 with a new no-name
motherboard. Bobspc has internet access through a dialup ppp
connection. Zeos has no network connection presently, and I want to
connect the two machines in order to use zeos as a backup for bobspc.
Both machines are running bo (1.3.1r6), and a 2.0.32 kernel and
bash version 2.00.0(1)-release.
Following are the relevant configuration files:
/etc/hosts - bobspc
127.0.0.1 localhost
192.168.0.1 bobspc bobspc.estar.net
192.168.0.2 zeos zeos.estar.net
/etc/hosts - zeos
127.0.0.1 localhost
192.168.0.2 zeos zeos.estar.net
192.168.0.1 bobspc bobspc.estar.net
I created a file /etc/init.d/local_net with the following:
/sbin/slattach -p cslip -s 19200 /dev/ttyS0 &
/sbin/ifconfig sl0 192.168.0.1 pointopoint 192.168.0.2 up
This file is run from /etc/init.d/boot after
/etc/rc.boot/0setserial is run.
During bootup the following messages are displayed:
SIOCSIFADDR: No such device
SIOCSIFDSTADDR: No such device
ifconfig sl0 gives no response, and ps -ax doesn't show an
slattach process.
Running /etc/init.d/local_net a second time (after booting is
complete) gives the same messages; ifconfig sl0 still gives no response,
but ps -ax now includes the line:
201 1 S 0:00 /sbin/slattach -p cslip -s 19200 /dev/ttyS0
Trying to telnet from one machine to the other gives the
following results:
root:vc-1:~>telnet zeos
Trying 192.168.0.2...
telnet: Unable to connect to remote host: Network is unreachable
A ping command gives similar results.
What am I missing?
Bob
