Thanks for replying (especially on a Sunday). This is right at the start of a new connection on port 11098 for Historical Data. No other data has been sent. Wireshark capture of Encoding Request: 0000 10 00 06 00 08 00 00 00 04 00 00 00 44 54 43 00 ········ ····DTC· Wireshark capture of the Encoding Response: 0000 0b 00 07 00 08 08 1a 03 44 54 43 ········ DTC The message coming back should not be length 0x0b, it is stating a size which is not documented. I have no problem whatsoever on the Listening Port 11099. I'm not in a better position, because if the encoding request is correct, which it looks to be, the server should not return that message. In fact, it should never send a message type 0x07 with length 0x0B, regardless of what junk someone fires at it. It should *always* be 0x10. I have attached a Wireshark PCAP file that shows the above behaviour. I'd be delighted to be proved wrong, but I don't think I am. |
