try-from - test program for the tcp_wrapper
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.
