Description Dan Astoorian 2003-09-19 04:04:57 AEST

The UseDNS option causes the OpenSSH daemon to perform a lookup of the remote
hostname (via getnameinfo() and/or getaddrinfo()) in certain appropriate
circumstances.  Although this is typically a DNS lookup, these routines could be
using a different name service such as /etc/hosts or NIS/NIS+.  In such cases,
the name of the option is misleading.

Moreover, there are some diagnostics within canohost.c which assume that
getnameinfo() is using DNS (e.g., "Nasty PTR record...")
