New patch for 2.11BSD on PDP-11: network DEUNA does not respond to ethernet broadcasts

by Jörg Hoppe

I found and patched an error in the network driver for UNIBUS ethernet controllers DEUNA/DELUA in 2.11BSD for PDP-11. Error reproduction: -------------------------- Build 2.11 BSD with ethernet/TCP/IP support over DEUNA/DELUA controller. Configure the network. Boot up 2.11 BSD, switch to multiuser mode. Wait for 15 Minutes, until all ARP caches in the system are aged out. Try to ping the PDP-11 from a network node, which is NOT listed anywhere in the PDP-11's network configuration files. Ping will fail. Important: since arp requests are also arp responses, do not ping the test node from your PDP-11. The test node may not be contacted by the PDP-11! Before testing, verify on the test node that the PDP-11 is unkown. The command "arp -a" must not display the PDP-11 yet. You can clean the test node's arp cache by executing "arp -d *". This can also be reproduced in SimH, for example with the installation downloadable at /www.ak6dn.com/PDP-11/2.11BSD/ Error explanation: -------------------- The DEUNA/DELUA does not answer ARP requests, so other network nodes can not get the PDP-11's ethernet MACID and can not send anything to it. The DEUNA/DELUA does not answer ARP because it does not receive ethernet broadcast packets (those addressed to MACID FF:FF:FF:FF:FF:FF). And it is not receiving broadcasts, because the DELUA driver in /sys/pdpif/if_de.c did not set up the DELUA's packet filter to receive FF:FF:FF:FF:FF:FF. Error patch --------------- In /sys/pdpif/if_de.c , the DEUNA/DELUA must be programmed to receive ethernet broadcast pakets. The good way would be to explicitly add MACID FF:FF:FF:FF:FF:FF to the filter. The fast and dirty way was to program the DELUA to receive ALL multicasts, by setting one more bit in the mode register: In /sys/pdpif/if_de.c, change line ds->ds_pcbb.pcbb2 = MOD_TPAD|MOD_HDX; into ds->ds_pcbb.pcbb2 = MOD_TPAD|MOD_HDX|MOD_ENAL; Status ----------------------------- This is a major bug, as it prevents the PDP-11 under 2.11BSD to run as a server. It's hard to believe that it is still there. In the typical quick "boot up and ping someone" test, it is almost invisible. The bug is not present in the DELQA driver "if_qe.c". I did posted already to alt.sys.pdp11 newsgroup. The error has been acknowledeged by one other user. In the BSD patch archive, this bug seems not to be addressed. regards Joerg Hoppe _______________________________________________ TUHS mailing list TUHS(a)minnie.tuhs.org https://minnie.tuhs.org/mailman/listinfo/tuhs

4.1cBSD Anyone?

by Benjamin Huntsman

Hi all! Just curious, has anyone here managed to get 4.1cBSD (or any 4.1 for that matter) running under SIMH or any other hardware or software? How does one prepare a SIMH-format distribution tape from a collection of files? I haven't found a whole lot of information on the subject, and I imagine it'd be fairly difficult to make a root dump without a pre-existing system... Many thanks to all in advance! _______________________________________________ TUHS mailing list TUHS(a)minnie.tuhs.org https://minnie.tuhs.org/mailman/listinfo/tuhs

Additions to the wiki

by Jason Stevens

I don't know if this would be the 'place' to ask, but would something like this be suitable to the TUHS wiki? http://gunkies.org/wiki/Installing_4.2_BSD_on_SIMH http://gunkies.org/wiki/Installing_4.3_BSD_Quasijarus_on_SIMH http://gunkies.org/wiki/Installing_4.3_BSD_RENO_on_SIMH http://gunkies.org/wiki/Installing_4.3_BSD_on_SIMH http://gunkies.org/wiki/Installing_Ultrix_4.0_on_SIMH I've been slowly putting together some documentation in some wiki like format on how to install various UNIXs into SIMH... Since I wrote them, they could just be wholesale imported... Anyways I don't know if they meet any standards, etc etc... Naturally I'll add 32v, 3BSD, 4BSD & 4.1BSD.... Thoughts? _______________________________________________ TUHS mailing list TUHS(a)minnie.tuhs.org https://minnie.tuhs.org/mailman/listinfo/tuhs

6th Edition RAID

by Carl Lowenstein

I thought I remembered something interesting about 6th Edition RK05 handlers, and went back to check RK(IV) in the manual. There it is, Raid 0. "Drive numbers (minor devices) of eight and larger are treated specially. Drive 8+x is the x+1 way interleaving of devices rk0 to rkx. Thus blocks on rk10 are distributed alternately among rk0, rk1, and rk2." Goes on to enumerate precautions, like don't use the same physical drive for both normal and interleaved operation. I myself never tried this, because I didn't have enough confidence in the error-free operation of a single RK05 drive, let alone two or more. Note that this feature disappeared by the time of 7th Edition RK(4). carl -- carl lowenstein marine physical lab u.c. san diego clowenstein(a)ucsd.edu _______________________________________________ TUHS mailing list TUHS(a)minnie.tuhs.org https://minnie.tuhs.org/mailman/listinfo/tuhs

Whence the 2.x BSD numbering?

by Warren Toomey

Can anybody explain why the 2BSDs that were distributed with kernel source code are numbered 2.8BSD upwards. Why start numbering at 8? P.S Actually I have a 2.79BSD in the archive which came out in 1979 just before 2.8BSD, so could it be that the '2.79' means 1979, and numbering followed incrementally after that? Cheers, Warren

Can't load split I&D files (in one PDP-11/23 PLUS)

by SPC

Well, the matter is simple: I'm trying to install 2.11 BSD in one PDP-11/23 PLUS with 4MB of ram, and the 'restor' and 'icheck' utilities don't load in he PDP, returning this message: "Can't load split I&D files" I tried with the diverse distributions of Vtserver and diverse versions of 'restor'. In the case of the 2.9BSD this don't happen but the utility can't understand what is the 'vt' device. Someone has encountered and solved this problem ? Regards Sergio
