Standalone test on Ubuntu 22.04 indicates that getnameinfo() fails with errno = 11 in library libetpan.

Will proceed to change the default setting to send_hostname=1 until this is fixed in underlying library (perhaps libetpan or other).

For reference, using send_hostname=0 works fine on macOS and Ubuntu 20.04.
