Let sl0 use eth0 in lan

nl1at · 03-03-2004, 06:15 AM

Hello all.
I'm trying to let sl0 use eth0.
The situation..
I've got an internal sliplink on sl0 to a application running in dosemu.
This works ok i can ping from and to the appl on the slackware 9.1 box.
But cant ping from lan to the appl .
Can ping from lan to sl0.
I activated ip_forward and sl0 uses eth0 out to lan which is ok but the packet that are send to reply aren't seen bij the slackbox.. (monitoring from the appl and with iptraf)
I've got no iptables rules running (should i?) (the box is on the lan behind freesco router)
the appl ip is 192.168.0.20
the sl0 ip is 192.168.0.19
the slackware 9.1 box eth0 is 192.168.0.10
the gateway is 192.168.0.1
Lan is 192.168.0.0
the slip script is like this..

Code:

slattach -s 38400 -p slip /dev/ptysa &
sleep 2
ifconfig sl0 192.168.0.19 netmask 255.255.255.255 mtu 1500 up
route add -host 192.168.0.20 dev sl0

What do i have to do to get trough to the appl?

Do i have to set a gw for the host on sl0?

I have solved the problem by using dsn0 with dosnet.o module from dosemu.

15.1. The DOSNET virtual device.

Dosnet.o is a kernel module that implements a special virtual network
device. In combination with pktdrv.c and libpacket.c, this will enable
multiple dosemu sessions and the linux kernel to be on a virtual
network. Each has it's own network device and ethernet address.

This works just great!!

Hello!

I have same kind of problem but i´m not running software with Dosemu in SL0

i just run an software in sl0. I can connect to my software from locally (ip192.168.0.6) but not from other computers on my LAN. How can i route the sl0 ip (192.168.0.6) so it´s detected by other computers too. Via eth0

Thanks.

I solved the problem with
arp -Ds 192.168.0.6 now the sl0 192.168.0.6 shows on every machine on my LAN.
