2 machines connected via de0. One of them (lisa) is connected to the
net via sl0. What i would like is to be able to talk to the world
through the other machine (bart) as well.
Both machines run the standard daemons with the default flags.
I ran routed -g on the box with sl0 for a while but except for a
"routed[53]: deleting route to interface sl0 (timed out)"
nothing else seemded to change. Ive also commented out routed
entirely, created a <gateways>, built a static routing table -
nothing doing; bart cant see the world. If its not a "host
unknown"/"network unreachable", its a hang.
The system is resolver only. My provider has records for both
the machines as nslookup verifies.
The only configuration defaults that i have changed are as follows:
For both boxes:
<hosts>
205.205.16.1 bart.rur.com bart
205.205.16.2 lisa.rur.com www.rur.com lisa
199.202.234.1 interlink.net slip-gateway
199.202.234.53 G338.257.interlink.net slip-modemIP
198.168.73.8 ns.interlink.net nameServer-1
198.168.54.8 ns.rezonet.net nameServer-2
in <host.conf> hosts precedes bind
<resolv.conf>
domain rur.com
nameserver 198.168.73.8
nameserver 198.168.54.8
The relevant <sysconfig> lines for lisa are:
network_interfaces="sl0 de0 lo0"
ifconfig_de0="inet 205.205.16.2 netmask 0xffffff00"
ifconfig_sl0="inet 199.202.234.53 199.202.234.1 netmask 0xffffff00"
ifconfig_lo0="inet localhost"
static_routes="multicast loopback"
route_multicast="224.0.0.0 -netmask 0xf0000000 -interface ${hostname}"
route_loopback="${hostname} localhost"
defaultrouter="199.202.234.1"
routedflags="-q"
and for bart they are the same except for:
network_interfaces="de0 lo0"
ifconfig_de0="inet 205.205.16.1 netmask 0xffffff00"
defaultrouter=NO
Both machines boot fine. On lisa I kermit to my provider, suspend
kermit and slattach -a -h -s 115200 /dev/cuaa1 and everything works:
netstat -nr
Routing tables
Internet:

inet 199.202.234.53 --> 199.202.234.1 netmask 0xffffff00
tun0: flags=10<POINTOPOINT> mtu 1500
Then i start to play with the route command on bart in an attempt
to give him a default route. To lisa? No. To slip-modemIP? No. To
slip-gateway? No.
I give up. What am i missing?
