++An expression of the form `[n:n:n:n:n:n:n:n]/m\' is interpreted as a
++`[net]/prefixlen\' pair. An IPv6 host address is matched if
++`prefixlen\' bits of `net\' is equal to the `prefixlen\' bits of the
++address. For example, the [net]/prefixlen pattern
++`[3ffe:505:2:1::]/64\' matches every address in the range
++`3ffe:505:2:1::\' through `3ffe:505:2:1:ffff:ffff:ffff:ffff\'.
++.IP \(bu
+ Wildcards `*\' and `?\' can be used to match hostnames or IP addresses. This
+ method of matching cannot be used in conjunction with `net/mask\' matching,
+ hostname matching beginning with `.\' or IP address matching ending with `.\'.

+Followup-To: poster
+Date: 8 Sep 1997 18:53:13 -0400
+Organization: Wietse's hangout while on sabattical in the USA
+Lines: 147

+
+The patch below adds a new host pattern to the TCP Wrapper access
+control language. Instead of a host name or address pattern, you
+can specify an external /file/name with host name or address
+patterns. The feature can be used recursively.
+
+The /file/name extension makes it easy to blacklist bad sites, for
+example, to block unwanted electronic mail when libwrap is linked
+into sendmail. Adding hosts to a simple text file is much easier
+than having to edit a more complex hosts.allow/deny file.
+
+I developed this a year or so ago as a substitute for NIS netgroups.
+At that time, I did not consider it of sufficient interest for
+inclusion in the TCP Wrapper distribution. How times have changed.
+
+The patch is relative to TCP Wrappers version 7.6. The main archive
+site is ftp://ftp.win.tue.nl/pub/security/tcp_wrappers_7.6.tar.gz
+
+Thanks to the Debian LINUX folks for expressing their interest in
+this patch.

+ .IP \(bu
++A string that begins with a `/\' character is treated as a file
++name. A host name or address is matched if it matches any host name
++or address pattern listed in the named file. The file format is
++zero or more lines with zero or more host name or address patterns
++separated by whitespace. A file name pattern can be used anywhere
++a host name or address pattern can be used.
++.IP \(bu
+ Wildcards `*\' and `?\' can be used to match hostnames or IP addresses. This
+ method of matching cannot be used in conjunction with `net/mask\' matching,
+ hostname matching beginning with `.\' or IP address matching ending with `.\'.

+.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.
