Package: syslog-ng
Version: 1.6.5-2
Severity: wishlist
Tags: patch
Please consider adding the attached patch to the syslog-ng package, it
is very small, but does great things. The patch comes from
http://dev.riseup.net/patches/syslog-ng/ and what it does is provide a
simple filter to strip out unwanted regular expressions from logs, as
well as an IP alias that enables you to strip out IP addresses from
your logs.
>From the README:
This patch adds the capability to syslog-ng that allows you to strip
out any given regexp or all IP addresses from log messages before they
are written to disk. The goal is to give the system administrator the
means to implement site logging policies, by allowing them easy
control over exactly what data they retain in their logfiles,
regardless of what a particular daemon might think is best.
The attached patch adds this capability to the syslog-ng debian
package. Additionally, I have fixed a grammar error in debian/control,
also fixed two lintian errors (it is required to have a versioned
depends on util-linux and debian/changelog needs to be valid UTF-8),
those fixes are included with the attached patch.

+
+ This patch adds the capability to syslog-ng that allows you to strip
+ out any given regexp or all IP addresses from log messages before
+ they are written to disk. The goal is to give the system administrator
+ the means to implement site logging policies, by allowing them easy
+ control over exactly what data they retain in their logfiles,
+ regardless of what a particular daemon might think is best.
+
+Background:
+
+ Data retention has become a hot legal topic for ISPs and other Online
+ Service Providers (OSPs). There are many instances where it is preferable
+ to keep less information on users than is collected by default on many
+ systems. In the United States it is not currently required to retain
+ data on users of a server, but you may be required to provide all data
+ on a user which you have retained. OSPs can protect themselves from legal
+ hassles and added work by choosing what data they wish to retain.
+
+ From "Best Practices for Online Service Providers"
+ (http://www.eff.org/osp):
+
+ As an intermediary, the OSP [Online Service Provider] finds itself in
+ a position to collect and store detailed information about its users
+ and their online activities that may be of great interest to third
+ parties. The USA PATRIOT Act also provides the government with
+ expanded powers to request this information. As a result, OSP owners
+ must deal with requests from law enforcement and lawyers to hand over
+ private user information and logs. Yet, compliance with these demands
+ takes away from an OSP's goal of providing users with reliable,
+ secure network services. In this paper, EFF offers some suggestions,
+ both legal and technical, for best practices that balance the needs
+ of OSPs and their users' privacy and civil liberties.
+
+ Rather than scrubbing the information you don't want in logs, this patch
+ ensures that the information is never written to disk. Also, for those
+ daemons which log through syslog facilities, this patch provides a
+ convenient single configuration to limit what you wish to log.
+

+Installing syslog-ng-anon
+
+ Applying the patch
+
+ This patch has been tested against the following versions of syslog-ng:
+ . version 1.9.5
+ . Debian package syslog-ng_1.9.5-2
+
+
+ To use this patch, obtain the source for syslog-ng
+ (http://www.balabit.com/downloads/syslog-ng/1.6/src/) and the latest
+ syslog-ng-anon patch (http://dev.riseup.net/patches/syslog-ng/).
+ Uncompress the syslog-ng source and then apply the patch:
+
+ % tar -zxvf syslog-ng.tar.gz
+ % cd syslog-ng
+ % patch -p3 < syslog-ng-anon.diff
+
+ Then compile and install syslog-ng as normal.
+
+ Debian package
+
+ Alternately, you can install syslog-ng-anon from this repository:
+ deb http://deb.riseup.net/debian unstable main
+
+ How to use it
+
+ This patch adds the filter "strip". For example:
+
+ filter f_strip {strip(<regexp>);};
+
+ This will strip out all matches of the regular expression on logs to
+ which the filter is applied. In place of a regular expression, you can
+ put "ips", which will remove all internet addresses. For example:
+
+ and the shortcut 'ips':
+
+ filter f_strip {strip(ips);};
+
+
+For a complete example, see the example syslog-ng-anon.conf.
