Now I'm stuck. I've installed IP networking on PCs, Macs, and Unix all
over campus for years. But can I get two Linux boxes to speak to each
other?
One 486-upgraded-to-P90-with-Evergreen, one cloney laptop, both
happily running RH5.2. Linuxconf adapter 1 in both cases, 3C509 in the
486, 3C589 in the laptop, both have been working on campus with fixed
IP addresses in these machines under this config. Take them home, run
thinwire between the BNC sockets (no jumper on either to switch
between sockets, so I assume the cards are auto-adaptive), properly
terminated off T-pieces. Disable DNS, make sure both machines have
each others' details in /etc/hosts, both are 143.239.128.* so bump the
netmask up to 255.255.255.0 and enable eth0.
Nothing. Nada. Zilch. Not a squeak. Ping just sits there and reports
100% packet loss like An Post on a bad day. Like they weren't even
connected. The embarrassing thing is that I've done this a dozen times
before with mixed hosts but never with two identical OS versions :-)
All clues gratefully received. It may just be tiredness (me, not the
machines).
