NAME
try-from - test program for the tcp_wrapper
SYNOPSIS
try-from
DESCRIPTION
The
try-from
command can be called via a remote shell command to find out
if the hostname and address are properly recognized
by the
tcp_wrapper
library, if username lookup works, and (SysV only) if the TLI
on top of IP heuristics work. Diagnostics are reported through
syslog(3)
and redirected to stderr.
