It s not exactly a DEC problem, but I know there are several people on HECnet running
simh under Linux and I m hoping somebody has already figured this one out.
I used to run simh (vax and pdp11 both) under Ubuntu 10.04 using Johnny s bridge
program and a tap device to connect to HECnet.
sudo tunctl -t tap0
sudo ifconfig tap0 up
sudo -b /usr/local/bin/hecnet-bridge 4711
the bridge.conf file (I ll post it if anybody wants) bridges tap0 with
Psilo.update.uu.se and in simh I would say
set xqb enabled
attach xqb tap0
and it worked great. Everybody was happy :-)
BUT, now I ve upgraded to Ubuntu 12.04 (Ok, I m not an early adopter!) and, as you
might guess, it doesn t work anymore. No errors and the tap0 device looks OK
bob at falsetto:~/legato$ ifconfig tap0
tap0 Link encap:Ethernet HWaddr c6:36:37:eb:16:7a
UP BROADCAST MULTICAST MTU:1500 Metric:1

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

but nothing ever happens. No data seems to pass between the bridge program and simh.
Is anybody else using Ubuntu? Did you run into this problem? Thanks,
Bob
