I have setup 2 286's in the following configuration: dopey has 2 ethernet cards: 1 connected to the 141 subnet, with an ip adress of 128.48.141.8, the other to the 144 subnet with an ip adress of 128.48.144.1 this is its autoexec file: hostname dopey.ucop.edu attach packet 0x66 nt2 3 1500 # this is on the 144 subnet attach packet 0x65 nt1 10 1500 # this is on the 141 subnet ifconfig nt1 netmask 0xffffff00 ip 128.48.141.8 broadcast 128.48.141.255 ifconfig nt2 netmask 0xffffff00 ip 128.48.144.1 broadcast 128.48.144.255 route add 128.48.141.0/24 nt1 route add 128.48.144.0/24 nt2 # # incorporate the local nameserver for lookups # domain addserver [128.48.141.1] #nile # # for broadcasts to work! # arp add 128.48.141.255 ether ff:ff:ff:ff:ff:ff arp add 128.48.144.255 ether ff:ff:ff:ff:ff:ff # some standard parameters ip ttl 16 tcp mss 216 tcp window 1500 # # start up the servers # start telnet start smtp start ftp start echo start discard start rip # # domain cache size 150 domain suffix ucop.edu route add default nt1 128.48.141.100 tintin has 1 ethernet card connected to the 144 subnet with an ip adress of 128.48.144.2, its autoexec file is: hostname tintin.ucop.edu attach packet 0x65 nt1 10 1500 # this is on the 144 subnet ifconfig nt1 netmask 0xffffff00 ip 128.48.144.2 broadcast 128.48.144.255 route add 128.48.144.0/24 nt1 # # incorporate the local nameserver for lookups # domain addserver [128.48.141.1] #nile # # for broadcasts to work! # arp add 128.48.144.255 ether ff:ff:ff:ff:ff:ff # some standard parameters ip ttl 16 tcp mss 216 tcp window 1500 # # start up the servers # start telnet start smtp start ftp start echo start discard start rip # domain cache size 150 domain suffix ucop.edu route add default nt1 128.48.141.100 dopey is supposed to act as a gateway 144 <-> 141 From other hosts, I can ping 128.48.141.8 (dopey's adress on the 141 subnet), but I can't ping any host on the 144 subnet. I turned the trace on . So if ping 128.48.144.1 (dopey) from 128.48.144.2 (tintin), from 144.2 I get the following output: Wed May 29 12:18:59 1991 - nt1 sent: Ether: len 42 00:00:c0:c6:3f:23->ff:ff:ff:ff:ff:ff type ARP ARP: len 28 hwtype 10 Mb Ethernet prot IP op REQUEST sender IPaddr 128.48.144.2 hwaddr 00:00:c0:c6:3f:23 target IPaddr 128.48.144.1 hwaddr 00:00:00:00:00:00 on 144.1 I get the following input: Wed May 29 14:14:11 1991 - nt2 recv: Ether: len 60 00:00:c0:c6:3f:23->ff:ff:ff:ff:ff:ff type ARP ARP: len 46 hwtype 10 Mb Ethernet prot IP op REQUEST sender IPaddr 128.48.144.2 hwaddr 00:00:c0:c6:3f:23 target IPaddr 128.48.144.1 hwaddr 00:00:00:00:00:00 the ping is unsuccessful. Is there something I am missing in the autoexec file ?? Many Thanks in Advance, Camille Iwanowitsch Kayruzian opschk@ganges.ucop.edu, 415 987 03 62

The rip add statement(s) for the broadcast addresse(s) of your subnets.
are missing, so that the hosts you ping don't know how to send the reply
to you.

Changing the attach command from: attach packet 0x60 en0 8 1500 to attach packet 0x60 en0 3 1500 did the trick, though I don't understand why! The only other trouble I had was with getting the 2nd interface configured. According to the ka9q docs I should have been able to do attach packet 0x61 en1 3 1500 129.78.144.3 instead it only worked if I did ip addr 129.78.144.3 attach packet 0x61 en1 3 1500 The mystery of why ka9q worked ok with the wd drivers and not with the clarkson ones will probably remain a mystery.

Hi, netters. I am setting up ka9q as a router between 2 ethernets: 141 and 144 subnets: Gateway PC has 2 wd8003e boards with adresses 144.8 and 141.8, Client PC has an adress of 144.2 ( 144 subnet has just 2 pc's ).
