Does that work with Hercules? Bob Hello! Actually yes. Hercules will emulate everything within reason up to the latest of the family members. Those are being added as the developers work on that little detail. For what Sampsa is planning he should have no problems outside of the usual ones. ----- Gregg C Levine gregg.drwho8 at gmail.com "This signature fought the Time Wars, time and again."

Reading a tutorial where they set up a TUN/TAP device for the CTC comms, but with NAT. Is there any way to make this interface look at a real ethernet interface on the host?

Works for me now. Steve- the link to your area is still down from GORVAX, everything ok? sampsa On 4 Aug 2012, at 23:18, Johnny Billquist wrote: On 2012-08-04 22:01, Peter Coghlan wrote: In another thread, Jordi Guillaumes i Pons <jg at jordi.guillaumes.name> wrote: PS: I have lost connectivity to UPDATE again.

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. Psilo, running the bridge at Update had restarted. Kicked the bridge. All should be ok now. Johnny

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

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? El 04/08/2012, a les 19:54, hvlems at zonnet.nl va escriure: The -CT for sure won't work with amulator. The -ST might provided the control unit is emulated and talks may be to a parallel (seriel ?) Interface on the host? ------Origineel bericht------ Well, Hercules emulates a CTCT (Channel-to-Channel) connection via TCP sockets which allows to connect two Hercules instances. Now, if anyone is up to develop a channel adapter in the simh side... :) Anyway, according to the Hercules docs: "Note: CTCT currently only supports IP traffic, so it cannot be used to transport NJE, SNA, PVM, etc. type payloads. This may change in the future." So it won't probably work even having a pair in SIMH. 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.
