+Followup-To: poster
+Date: 8 Sep 1997 18:53:13 -0400
+Organization: Wietse's hangout while on sabattical in the USA
+Lines: 147
+Sender: wietse@spike.porcupine.org
+Message-ID: <5v1vkp$h4f$1@spike.porcupine.org>
+NNTP-Posting-Host: spike.porcupine.org
+Xref: news.porcupine.org comp.mail.sendmail:3541 comp.security.unix:7158
+
+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.
+

+.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.

+.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
+
