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.

       Example:

       rsh host /usr/sbin/try-from

SEE ALSO

       hosts_access(5), hosts_options(5), tcpd(8)
