- +.SH NAME
- +try-from \- test program for the tcp_wrapper
- +.SH SYNOPSIS
- +.B try-from
- +.SH DESCRIPTION
- +The
- +.B try\-from
- +command can be called via a remote shell command to find out
- +if the hostname and address are properly recognized
- +by the
- +.B tcp_wrapper
- +library, if username lookup works, and (SysV only) if the TLI
- +on top of IP heuristics work. Diagnostics are reported through
- +.BR syslog (3)
- +and redirected to stderr.
- +
- +Example:
- +
- +rsh host /usr/sbin/try\-from

- +.TH SAFE_FINGER 8 "21th June 1997" Linux "Linux Programmer's Manual"
- +.SH NAME
- +safe_finger \- finger client wrapper that protects against nasty stuff
- +from finger servers
- +.SH SYNOPSIS
- +.B safe_finger [finger_options]
- +.SH DESCRIPTION
- +The
- +.B safe_finger
- +command protects against nasty stuff from finger servers. Use this
- +program for automatic reverse finger probes from the
- +.B tcp_wrapper
- +.B (tcpd)
- +, not the raw finger command. The
- +.B 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.
- +.B 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.
- +.B safe_finger
- +takes care of all this badness.
