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

NAME

       safe_finger - finger client wrapper that protects against nasty stuff from finger servers

SYNOPSIS

       safe_finger [finger_options]

DESCRIPTION

       The  safe_finger  command  protects  against nasty stuff from finger servers. Use this program for automatic reverse finger probes from the
       tcp_wrapper (tcpd) , not the raw finger command. The safe_finger command makes sure that the finger client is not run with root privileges.
       It  also  runs  the finger client with a defined PATH environment.  safe_finger will also protect you from problems caused by the output of
       some finger servers. The problem: some programs may react to stuff in the first column. Other programs may get upset by thrash anywhere	on
       a  line.  File  systems may fill up as the finger server keeps sending data. Text editors may bomb out on extremely long lines.	The finger
       server may take forever because it is somehow wedged.  safe_finger takes care of all this badness.
