Welcome to LinuxSecure
I found some scripts on my workstation that have not been
published and may be interesting for some people. Actually, I will not prepare them for publishing, but you can
contact me, if you are interested in one or more of them.
- A tool for the backup of network components. The script runs as a daemon and can be configured via config files.
It reads in the config files containing the passwords of the components once, so you can store them in a crypt storage.
There exist severeal templates for ssh, scp, telnet. The intention is to make automated backups from router, switches, firewalls etc.
- Postfixanalyser was written for the trendmicro mail virusscanner. You can search for mails and you will get a
status for the found mails: when did the system receive it, when was it working with the mail the last time, whats the status of the
mail, where there any problem while delivering the mail. The second feature was a simple statistic: bytes and number of mails received and send,
mails by status (received from extern, queued, sent to trend, received from trend, queued, delivered) and mails by problem
(deferred and not sent to scanner (scanner rejected), deferred and not sent to scanner (scanner down), sent to trend, but deferred before,
dereffed and not sent to extern (mta rejected), deferred and not sent to extern (mta down), sent to extern, but deferred befor).
- A logscanner and a scanner for the checkpoint objects file.
- A tool, that parses the registry of the genugate firewall and produces a more human readable output in html.
- A ftp-script for the honeynet.
- Various backupscripts in Perl and Bash.
- Various iptables scrips.
- A script called minilinux to create a small linux out of a huge running system.
- Pigsparty was a small projetct that was never finished. The idea was to convert snort rule sets into iptables rule sets.
- A snort admin interface in php.
- A perlmodule and some programs (e.g. mfl) for the preparation and analysis of longitudinal data with a focus of same domains.

"Traditional analysis of filesystem performance focuses on block I/O
statistics?what you commonly see printed by the iostat(1) tool and plotted
by many performance-monitoring GUIs. Those statistics show how the disks
are performing, but not really the filesystem. Often you care more about
the filesystem's performance than the disks, since it's the filesystem that
applications make requests to and wait for. And the performance of
filesystems can be quite different from that of disks! Filesystems may
serve reads entirely from memory cache and also populate that cache via a
read-ahead algorithm and for write-back caching. xfsslower shows filesystem
performance?what the applications directly experience."|

Management Engine(ME), which is a separate processor and operating
system running outside of user control on most x86 systems, has long been
of concern to users who are security and privacy conscious. Google and
been working on ways to eliminate as much of that functionality as possible
(while still being able to boot and run the system). Ronald Minnich from
Google came to Prague to talk about those efforts at the 2017 Embedded
Linux Conference Europe.

|When he released4.14, Linus Torvalds
warned that the 4.15 merge window might be shorter than usual due to the US
Thanksgiving holiday. Subsystem maintainers would appear to have heard
him; as of this writing, over 8,800 non-merge changesets have been pulled
into the mainline since the opening of the 4.15 merge window. Read on for

|Google has announcedthat it has released its container-difftool under the Apache v2 license.
"container-diff helps users investigate image changes by computing semantic diffs between images. What this means is that container-diff figures out on a low-level what data changed, and then combines this with an understanding of package manager information to output this information in a format that?s actually readable to users. The tool can find differences in system packages, language-level packages, and files in a container image.
Users can specify images in several formats - from local Docker daemon (using the prefix `daemon://` on the image path), a remote registry (using the prefix `remote://`), or a file in the .tar in the format exported by "docker save"command. You can also combine these formats to compute the diff between a local version of an image and a remote version."|

|Observers of the kernel's commit stream or mailing lists will have seen a
certain amount of traffic referring to the addition of SPDX license
identifiers to kernel
source files. For many, this may be their first encounter with SPDX. But
the SPDX effort has been going on for some years; this article describes
SPDX, along with why and how the kernel community intends to use it.

|The NumPy project is phasing
outsupport for Python 2. "The Python core team plans to stop
supporting Python 2 in 2020. The NumPy project has supported both Python 2
and Python 3 in parallel since 2010, and has found that supporting Python 2
is an increasing burden on our limited resources; thus, we plan to
eventually drop Python 2 support as well. Now that we're entering the final
years of community-supported Python 2, the NumPy project wants to clarify
our plans, with the goal of to helping our downstream ecosystem make plans
and accomplish the transition with as little disruption as
possible."NumPy releases will fully support both Python 2 and
Python 3 until December 31, 2018. New feature releases will support only
Python 3 as of January 1, 2019. (Thanks to Nathaniel Smith)
|NumPy will drop Python 2 support|
|After 16 years of evolution, the SciPyproject has reached version
1.0. SciPy, a free-software project, has become one of the most
popular computational toolkits for scientists from a wide range of
disciplines, and is largely responsible for the ascendancy of Python
in many areas of scientific research. While the 1.0 release is
significant, much of the underlying software has been stable
for some time; the "1.0"version number reflects that
the project as a whole is on solid footing.
