| Summary | 0002941: CCDCiel discovery find only one of two Alpaca servers | ||||
| Description | My Sky simulator has Alpaca server address 127.0.0.1, port 11111. When I use a com device in Ascom 7 is starts a second Alpaca server 127.0.0.1, port 32323. CCDciel sees the only the Ascom7 server. Fix to discover both servers: cu_alpacamanagement.pas: Line 354 - if not f_loopback then Result.Add('127.0.0.1'); + {A unicast datagram to 127.0.0.1 reaches only ONE of the sockets bound to the discovery port, so a second Alpaca server on the same machine - ASCOM 7 starts one automatically - is silently invisible. The loopback broadcast address is delivered to every socket bound with SO_REUSEADDR, so all local servers answer.} if not f_loopback then begin Result.Add('127.255.255.255'); Result.Add('127.0.0.1'); end; Keeping 127.0.0.1 as well costs one extra datagram and covers any server that binds the loopback address explicitly rather than 0.0.0.0; the duplicate check drops the second reply from a server that answers both. | ||||

Thank you, I have not tested that before. I apply your change and I confirm this also fix the problem on Linux. https://github.com/pchev/ccdciel/commit/073091295d2e6face67185ce446512d3dc0ea4e5 |
