Problem encode RAW packet [Length] #59

Closed hafedh-trimeche closed 4 years ago

hafedh-trimeche commented 4 years ago

I try to send 0800 command by generating this packet (Length included). The server seams that only accepts packets not including length header. 0048080002200000080000000511214416663881936400299162

Would please indicate me how to force server accept the packet's length?

Would also the packet be sent as Text or Binary or HEX format? Visa Base I uses HEX and EBCDIC to convert fields.

Config: { "dangerous":false, "echoServerPort":5000, "lengthIncludeHeader":false, "listenPort":8711, "logFile":"log.txt", "overrides":"1:bitmap-hex:8", "upstreamHost":"localhost", "upstreamPort":5000, "useHeader":true, "vv":true }

Hi, Hafedh!

It works with the length header only between hosts. So it doesn't read the header sent by a client side.
