Subject: Bind to loopback interface by default
X-Git-Tag: 0.4.0~15
X-Git-Url: https://mudpy.org/gitweb?p=mudpy.git;a=commitdiff_plain;h=b6271bdc166aed6d8476d3a4d2bb6fdd39350e2e;hp=7e931fbecad469af11ee336714e711d67f9f84d4

Bind to loopback interface by default

Adjust the fallback behavior for otherwise unconfigured address
binding to match the safe posture adopted in the sample
configuration.
