Turn off IPv6 support

[duckunix]

Is there a way to disable the need for IPv6 when running trustd-pm? My test environment has a restriction against running IPv6, and it errors out on start up. Error below:

 ./trustd-pm

IIRC you can control this by the bind address. Which is defaulting to ::1, meaning (local-loopback IPv6) and should bind to both v4 and v6.

You can use HTTP_SERVER_BIND_ADDR or --http-server-bind-address to override this. Setting it to 127.0.0.1 should bind this to "IPv4 localhost".

Btw, you can also use :: (IPv6 any) and 0.0.0.0 (IPv4 any).
