[HECnet] HECnet bridge and tun/tap problems on Ubuntu 12.04 ...

Mark, I don't think Bob suggested he used some special program to connect simh to a tap device. What he did was use my bridge to connect his machines to HECnet, which is a step on the other side of the tap device. By the way, Bob, I know that I've seen a patch to simh in the past, to connect to HECnet directly from simh, without the addition of the bridge program. Maybe something to use?

There is integrated support for tap devices, and there also is support for the more generic vde networking capabilities. The latest source is available at: https://github.com/simh/simh/archive/master.zip To build on Ubuntu 12.0.4 the first time, as root you may need to: # apt-get install libpcap-dev # apt-get install libvdeplug2-dev Then as a normal user: $ make vax -Mark *From:*owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] *On Behalf Of *Bob Armstrong *Sent:* Sunday, November 10, 2013 9:08 AM *To:* hecnet at Update.UU.SE *Subject:* [HECnet] HECnet bridge and tun/tap problems on Ubuntu 12.04 ... 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 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) 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?
