Hi,
I have recently upgraded one of my machines to 2.2 Stable from August 1 and I
seem to be having a lot of problems trying to get that machine to listen on i
the LAN.
My configuration is as follows:
Machine one is running FREEBSD 2.1.0 at address 128.66.12.3
Machine two is running FREEBSD 2.2 Stable 08/01/96 at address 128.66.12.1
Each machine has a DE203 card and the connection is terminated at both sides.
The 2.2 machine, refuses to listen on to the network, and I can not figure
why. I have tried to eliminate all the hardware variables by changing the
cable and swapping the lan cards. No matter what I do, I still get the same
results. I also noticed that when I used PPP on machine 2 in the past
the routing table was updated no problem. Now I have to add an extra route
to the gateway to get things going.
I would appreciate any help on the matter.
please reply to root@garfield.inx.net
Thanx
Constantine.
More info is as follows :
Aphrodite: 128.66.12.1
le0 is a DEC 203
/etc/sysconfig:ifconfig_lo0="inet localhost"
/etc/sysconfig:ifconfig_le0="inet 128.66.12.1 netmask 255.255.255.0 "
/etc/netstart:route add 224.0.0.2 127.0.0.1
/etc/netstart:route add 128.66.12.1 127.0.0.1
The last 2 statements are needed in order to avoid a buffer overflow on the
lan card.
