Re: [Simh] EXT : simh on openvms (to get a VAX on top of an OpenVMS Itanium) >> network issue

2016-03-28 Thread Hittner, David T (IS) 
There was an early restriction on PCAP-VMS where the host had to assign a 
TCP/IP address to the host interface(s) being used for PCAP-VMS, even if you 
aren’t planning on using that host address, in order to “bind” PCAP-VMS on that 
interface. I don’t know if the TCP/IP address restriction was ever lifted.
Thus, PCAP-VMS probably won’t work in startup_p1 “MIN” mode, unless you 
manually start TC/IP networking and assign a TCP/IP address to the host 
interface(s).

Thanks a lot for these precisions.
I have just contacted VSI, and we will see what they say.
If anyone thinks he could help on the very difficult subject of VMS internals 
involved here, and has not an i4 on OpenVMS 8.4-1h1 in his laboratory, he 
should contact me and use my environment by vpn.

Just as a guess, does the newer rx2800 use TOE (TCP Offload Engine) network

behavior enough that PCAP-VMS may no longer work.

Hello,
I need help for pcap-vms. I use (vax-)simh on top of OpenVMS (VSI) Itanium i4.
I tested vax-simh (simh 4.0 beta) and pcap-vms on OpenVMS on an Itanium rx2660, 
and it worked fine.
On OpenVMS i4 (rx2880), with exactly the same configuration, and images, I can 
see my NICs from the simh prompt (sho eth), I can attach a device (attach xq0 
ethn), assign it a mac address, and my VAX-VMS on top of simh sees the emulated 
device, can send data, but does not receive anything.
Can you give me advice, way of tracing the problem, hypothesis ?
I tried to boot the OpenVMS host in startup_p1 MIN, to test if I get the same 
problem when there is no network software on the host (like DecNet, or Tcpip), 
and the problem remains.
I rebuilt the pcap-vms from scratch on the i4 host, and the problem remains.
Do you think there could be an hardware issue, like the NIC which cannot work 
in promiscuitus mode ?
Any help should be welcomed,

[Simh] Interdata OS/32 package

2016-03-28 Thread Don Stalkowski 
Hello Interdata fans,

I've put together an OS/32 package consisting of instructions on
installing OS/32, a console log from that install, and a tape of
a new sysgen file.

This is not a pre-built disk image but rather a DIY install that uses
tapes from bitsavers. It's for those who actually want to have some fun
and learn about OS/32.

The package is temporarily at:

 

A permanent home would be nice.

My thanks to Davis Johnson for his invaluable help in getting OS/32
and MTM running.

Don

Re: [Simh] EXT : simh on openvms (to get a VAX on top of an OpenVMS Itanium) >> network issue

2016-03-28 Thread Mark Pizzolato 
Hi Gérard,
Are you running the same version of OpenVMS on both the rx2660 which worked and 
the rx2880 which didn’t?
I asked if you’ve observed any packets making it to the wire.  Did you check 
that?
One way or another there may be a problem putting packets on the wire, there 
may be a problem receiving packets from the wire, or Both.

This might indeed be a factor if the kernel interfaces to pass data to the TOE 
are different than the interfaces which the drivers is using.
The current sim_ether code is completely tolerant of jumbo packets and/or 
interactions with a TOE as long as the packet capture interface can actually 
get data (at least for IPv4 traffic, IPv6 is a round-tuit project).
If there is a TOE in the picture, maybe there is a mechanism to disable it 
which would hopefully get the desired kernel interfaces to be used and let 
pcap_vms work…
