The issue appears to be that you can’t disable ipv6, even if you don’t need it, because
of how the one piece of code is written. The web interface messes up the formatting, but
the error message matches the code block in the original note, and it only occurs here:
pi@pi2b:~/OpenSprinklerGen2 $ grep -B3 -A1 -n ‘create shell listen socket’ *
etherport.cpp-57-
etherport.cpp-58- if ((m_sock = socket(PF_INET6, SOCK_STREAM, 0)) < 0)
etherport.cpp-59- {
etherport.cpp:60: DEBUG_PRINTLN(“can’t create shell listen socket”);
etherport.cpp-61- return false;
