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
