windows 10 LAN lsl fail #360

Open dmedine opened 6 years ago

dmedine commented 6 years ago

I am having trouble getting LSL to do 2 way communication on windows 10 LANs. I had this problem before, and deleting all the virtual hyper ethernet adapters fixed it, but not this time. Basically I have two pcs connected directly, they can ping each other, but I can only send LSL streams 1 way, from my Windows 10 to the other pc which is running Windows 7. I understood this to be an issue having to do with LSL not being able to handle multiple network adapters, but now there is only 1 and the bloody thing still won't go. Anyone know about this?

Have you turned off all the firewalls? Are you using the standard SendString, ReceiveString examples? Are you on a wired network?

P.S. I generally use windows 10<-> Ubuntu these days for LSL stuff.

Wired. Firewalls disabled. PCs can ping each other. LSL goes out of Windows 10 to Windows , but not vice versa. Like I said, I've encountered this before, but disabling the virtual network adapters solved it.

I can send you a work in progress build with some more debug logging, so far I haven't been able to reproduce that issue reliably so maybe Windows 10 being always broken can help thete

You should try updating to the latest liblsl (build from source) on both endpoints.

Also try turning off ipv6 on both endpoints. I fixed one issue with ipv6, but I'm not convinced that I fixed them all.

I've uploaded the example apps with some debug messages enabled http://trstan.stennr.de/Chatty_examples_for_David.7z You can redirect the output by adding > outputfile.txt from the command line, e.g. SendDataC.exe > senderlog.txt.
