Slip Connection

[mulderbaba]

Hi all,

I established a slip connection between a linux machine and dos
machine wtih the commands below..

slattach -p slip -s 9600 /dev/ttyS0 &
ifconfig sl0 linux_ip_addr pointopoint dos_ip_addr netmask
255.255.255.0
route add dos_ip_addr sl0

SLIP connection is configured as linux_ip_addr at linux machine end
and dos_ip_addr at the dos machine end. I can ping dos machine from
linux machine. (I have a program running in dos machine to reply ping
packets.) But i cannot ping dos machine from other computers on the
network. I am new to networking in linux. Should i add new entries
into routing table or solution is something else?

This will provide only communication between the hosts on either end
of the SLIP connection.

You should also have

1) dos_ip_addr belong to the same network as linux_ip_addr.
2) IP forwarding in the Linux kernel and turned on.
3) proxy arp set up on the linux host for the dos host.
