+.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.
+.SH SEE ALSO
+.BR hosts_access (5),
+.BR hosts_options (5),
+.BR tcpd (8)
+.SH AUTHOR
+Wietse Venema, Eindhoven University of Technology, The Netherlands.

++.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.
++.SH SEE ALSO
++.BR hosts_access (5),
++.BR hosts_options (5),
++.BR tcpd (8)

++.TH TRY-FROM 8 "21th June 1997" Linux "Linux Programmer's Manual"
++.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

+;; IPv6 patch for tcp_wrappers_7.6 1.14
+;; Dec 29, 2001 by Hajimu UMEMOTO <ume@mahoroba.org>
+;;
+;; This patch supports IPv4/IPv6 dual stack and IPv4-mapped IPv6 address.
+;; You can replace stock tcpd or libwrap.a with this.
+;; IPv6 address pattern is as a `[net]/prefixlen' pair.
+;; This patch was tested on KAME/FreeBSD, KAME/FreeBSD3, KAME/NetBSD,
+;; RedHat 5.1 with kernel 2.1.126, and RedHat 6.0 with kernel 2.2.10.
+;; Solaris 8 is now supported. Thanks Alexander Gall <gall@switch.ch>
+;; and Shigechika AIKAWA <shige@cin.nihon-u.ac.jp>.
+;;
+;; This version is using getaddrinfo()/getnameinfo() instead of
+;; getipnode*() to support scoped address. Use of
+;; getaddrinfo()/getnameinfo() and scoped address support is only
+;; tested on KAME.
+;;
+;; CAUTION:
+;; Back out change for field separater. Now, field separater is `:'
+;; not `|'. To specify IPv6 address, enclose IPv6 address with `['
+;; and `]'.
+;;
+;; For Linux users:
+;; If your libc doesn't have sockaddr_storage, try target `linux-old'.

+.TH TRY-FROM 8 "21th June 1997" Linux "Linux Programmer's Manual"
+.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
+
+.SH SEE ALSO
+.BR hosts_access (5),

+.BR tcpd (8)
