I just had an absolutely insane idea: I'm gonna run Debian S/390 and try to get the DECNET stack running on that. What do you guys think? Sampsa

Connectivity problems

by sampsa＠mac.com

Same here, my bridge to UPDATE is down. Multinet tunnel to areas 2,3 and 59 are up, link to 19 is down.

It appears from here that SG1 might be down or unreachable but I don't think that accounts for all that seems to be wrong. Regards, Peter Coghlan.

Managed to get an emulated S/390 with MVS up - any way we can get this beast onto HECnet?

by hvlems＠zonnet.nl

Jordi, I feel that the software ony implementation of the gateway product may be your best shot. Even then, hardfware was required to make the connection. The spd for the host based (software) SNA gateway product is perhaps a good start. -----Original Message----- From: Jordi Guillaumes i Pons <jg at jordi.guillaumes.name> Sender: owner-hecnet at Update.UU.SE Date: Sat, 4 Aug 2012 20:12:13 To: <hecnet at Update.UU.SE> Reply-To: hecnet at Update.UU.SESubject: Re: [HECnet] Managed to get an emulated S/390 with MVS up - any way we can get this beast onto HECnet?

As for the -ST version, this could be encouraging: "( Preliminary 2703 BSC Support ) Describes a BSC emulation line entry to either link 2 Hercules engines or a custom made program emulating a 2780, 3780 or 3x74, or a custom made program interfacing to a real BSC line. The communication is emulated over a TCP connection. All bytes are transfered as-is (except for doubling DLE in transparent mode) just like it would over a real BSC link. Emulated EIA (DCD, DTR, CTS, etc..) or X.21/V.11 leads (C, T, etc..) are treated differently depending on the DIAL option selected. The line emulates a point-to-point BSC link. There is no point-to-multipoint handling." Again, my MVS expertise lies far away from net/comms, so I'm not sure if this could do the trick.

For various reasons to do with my general mental stability etc, I decided to learn about IBM mainframes, so got one running.. Any way to connect this to DECnet? Maybe over over DECNet-OSI since the thing natively does VTAM? Details: http://sampsa.com/2012/08/04/mvs-on-an-s390-because-openvms-is-just-too-eas… But what are you running Hercules on? I've got Hercules running under VMS on an Alpha. Whatever it says about my mental stability, I can even get it to crawl along on VAX/VMS. I'm running VM/370 and MUSIC under Hercules but neither knows anything about DECnet so even though Hercules is running on machines attached to HECnet, I'm no closer to being able to connect to or interact with either OS over HECnet. I've seen enough of DECnet-OSI at work to know I am not really interested in trying to use it. Regards, Peter Coghlan.
