+.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.

|
||
|
|
+.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 /some/where/try\-from
