IPV6 listener ERROR on binding: Address family not supported by protocol

Legato Application Framework
41

As said before, this is not legato problem as you also see problem in pc

Hi have to finally write application in Legato. Doesn’t matter to me if the problem is still there on PC.

Would like to see it working on the module side and that is more than enough for me.

You can make it work on nc tool first instead of legato app, that is why you can try in linux pc and compare the setting.

Just found that SSH with IPV6 via USB ECM interface is OK:

You can try SSH connection on port 22 and see if it works.

BTW, I have also tried on USB ECM port for TCP server via IPV6, no problem is found:


//to put module to TCP server:
./nc.netcat-openbsd -6 -l 666

//Ubuntu PC:
owner@ubuntu:~$ nc.openbsd -6v fe80::383d:82ff:fed0:997c%usb0 666
Connection to fe80::383d:82ff:fed0:997c%usb0 666 port [tcp/*] succeeded!
