Finally got another machine for my wife & kids to use (utopia,
192.168.0.2), & want to connect it to my FreeBSD box (riposte,
192.168.0.1) so that the new machine can access the Internet, and have
backup through the DAT tape drive on the FreeBSD box. Unfortunately, I
cant ping in either direction. Because of cost, an old message from Mr
Smorgrav recommending them, & because my old FreeBSD machine has had
past troubles with its PCI slots (couldnt get an early Adaptec 2940 PCI
to work, using ISA 1540CP instead), I'm using Kingston KNE20T ISA cards
with PnP disabled on the FreeBSD side. Both machines can ping their own
interface, but I get 'host unreachable' messages on utopia.
The included DOS qstart utility is able to transmit to & receive from
the other machine (giving me some confidence that the hub, patch cords,
and the NICs are functioning). There's only one media type on this
card. I made sure utopia knows its IP address, and that 192.168.0.1 is
its default gateway. I checked /etc/host.conf, resolv.conf (contains
only nameserver entries for my ISP & work nets), and made entries in
/etc/hosts as below. I disabled IP filter, re-enabled inetd, and made
entries in rc.conf (& rebooted). I reread the tutorial on user PPP
aliasing, netintro(4), etc, without enlightenment. I re-examined
hardware settings & dmesg looking for IRQ or port clashes. Wanted to
check for past experience, but the mail archive search engine has been
down for a while. So how to proceed? Would tcpdump be of any use?
Please cc me as I'm not on the list. If it makes a difference, riposte
had a binary upgrade from 2.2.7, and has a generic 3.4 kernel.
