[SOLVED]Can´t reach a port listening vía rmnet0 interface

You also need to disable the firewall of module:

iptables -I INPUT -j ACCEPT

You can also try this TCP server application:

Networking: TCP server Operation not permitted (errno -1)

Hi, Thanks for the response, unfortunately I already tried to implement it via a fdMonitor but it give me the same error(s) when calling the recv functionallity: either: Errno -1: Operation not permitted Errno -11: Unknown error I discovered that when I use the flag MSG_DONTWAIT in the recv function that I get the errors as described above. But when I just set the flag to 0 than I can receive data without a problem. However I want a non-blocking socket, so I want to use the flag MSG_DONTWAI…

Or you can download the nc binary here:

jakev/android-binaries/blob/master/nc

Transfer to the WP module, and then type the following for TCP server:
root@swi-mdm9x28:/tmp# chmod 777 ./nc
root@swi-mdm9x28:/tmp# ./nc -l -p 1234
