project Issue with TCP requests from 2nd computer

5:43pm Tue 14th May, ANONYMOUS

Hi! My group has encountered an issue with communicating between 2 computers. Everything works as expected for UDP communication but not all TCP works. Our set up is like this: Computer 1: IP Address 172.20.10.14 ./station-server StationA 4001 4002 127.0.0.1:4006 172.20.10.9:4010 & ./station-server TerminalB 4003 4004 172.20.10.9:4008 & ./station-server JunctionC 4005 4006 127.0.0.1:4002 172.20.10.9:4008 & Computer 2: IP Address 172.20.10.9 ./station-server BusportD 4007 4008 172.20.10.14:4004 172.20.10.14:4006 & ./station-server StationE 4009 4010 172.20.10.14:4002 127.0.0.1:4012 & ./station-server TerminalF 4011 4012 127.0.0.1:4010 & If we request a route starting at A/B/C on Computer 1 or D/E/F on Computer 2 there are no issues. But if we request routes the other way around (i.e. D from Computer 1 or B from Computer 2) the requests fail. Nothing is received at either end. For example the request Station B->C (route is B->D->C) below works if initiated from Computer 1 but not on Computer 2: http://172.20.10.14:4003/?to=JunctionC&leave=12%3A58 We're a bit stuck on how to move forward so any help would be greatly appreciated! Thanks.
