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 sys‐
log(3) and redirected to stderr.

Example:

rsh host /usr/sbin/try-from
