Table of Contents
new application: yumbootstrap
New application has arrived. yumbootstrap is a chroot installer for distributions that use Yum as their package manager. As the name suggests, it's a RPM clone for debootstrap.
new sections: my modules
I have added new sections to this page that provide links to modules (for Perl, Python and Ruby) I have written. There's no Python modules yet, but this should change in the future.
new application: DashWiki
New application became mature enough to be published: DashWiki. This is a wiki engine focused on defining dashboards.
flowmon rewrite
New version of flowmon is out. It's an almost complete rewrite, now with way better internal architecture. flowmon is now usable with monitoring systems, not only an interactive tool.
cfgen v1.1
New version of cfgen is out. Added possibility of defining variables for all hosts and command line option for parameters inspection.
cfauditdump v0.9
Home page for new tool was added: cfauditdump.
Welcome to the page dedicated to tools written by dozzie (GPG public key).
Most (all?) of these tools are written with system administrator's tasks in mind, so they address specific needs encountered by sysadmin (by me, in this case).

Projects
All the projects can be found here: http://dozzie.jarowit.net/code/. Some may also be published on GitHub. Perl modules are certainly pushed to CPAN.
The projects are managed in git version control system, so you'll need to learn it a bit if you want to access the code (though each tool has a short how-to-get instructions provided). History can be viewed on local gitweb instance.
No tarballs with code are provided, at least for now.
Tools descriptions
cfauditdump
Tool that dumps audit database coming from cfengine 2.x (3.x in BerkeleyDB format works as well) in YAML format.
cfgen
Config generator that uses templates ( Template::Toolkit) parametrized with YAML files filled with values for each host.
cronbuilder
Tool that pulls sources from one repository, builds them using supplied command and pushes changes to another repository.
Not a difficult thing, but constant rewritting scripts (to keep silence when no changes were made) is annoying when it comes to details.
DashWiki
Wiki engine for dashboards. DashWiki integrates data from different sources (through XML-RPC, HTTP and such) and allows easy creation of dashboards, releasing sysadmin from necessity of writing web applications over and over again.
flowmon
Network flow monitor. Displays traffic summaries for flows, which are defined by BPF filters.
You can think of this being similar iftop.
munc
Netcat multiplexer.
TODO: be more specific about munc.
SSL-enabled rsync
The Right Way(tm) of doing rsync over SSL. Uses stunnel 4.x.
pwgen
pwgen is a password generator producing passwords that are easy to remember.
This is translation original pwgen tool (well, at least a generation algorithm) to Perl and Python languages.
sftponly
Remember scponly, a shell providing copy-only access to users?
Want to close them in chroot() environment?
Don't want to bother with creating full-blown chroot() or even small /dev contents?
This is the (my) way to go.
sftponly doesn't need any files -- especially device files -- in user's home directory, so it's quite easy to manage multiple copy-only accounts. Your users will not be able to break their environment anymore.
Time Shifter
Tool for changing reported time for specific processes.
When you need to change current time for some processes, but not for the whole system or when you just can't change the time for the system (no root privileges).
OpenVZ stats
Little daemon that collects OpenVZ statistics in guest system and pushes them to collectd.
Requires that collectd has UnixSock plugin enabled.
XML-RPC daemon
Daemon and shell client utility, both using XML-RPC protocol wrapped in SSL and provided with HTTP authentication.
Daemon is just a trivial HTTP server, that passes XML-RPC calls to appropriate Perl scripts. It's just simpler to configure such a small daemon than Apache, lighttpd or nginx.
yumbootstrap
Chroot installer for distributions that use Yum (mainly Red Hat, CentOS and Fedora). As the name suggests, it's a RPM clone for debootstrap.
Perl modules
App::Getconf
Module aiming at keeping configuration coming from different sources: configuration files and command line. API influenced by Log::Log4perl.
Log::Message::JSON
Module for structured logging. Log::Message::JSON is basically a hash(ref) that magically stringifies to JSON when necessary.
Log::Log4perl::Appender::Fluent
Module for structured logging. It's a Log::Log4perl appender that submits data to Fluentd. It works with plain strings, but when passed Log::Message::JSON or Log::Message::Structured, it passes full structure.
Sys::Facter
Perl clone of Facter, compatible with pfacter.
Python modules
Nothing published yet
Ruby modules
Test::TAP::More
Simple test framework for Ruby. Mimics excellent Test::More module and is a TAP producer.
Erlang applications
Indira
Helper library making starting Erlang code as a daemon way easier.
xmerlrpc
XML-RPC client and server library.
exmlrpcd
Simple XML-RPC daemon in Erlang.
ENI
INI-like file loader library.
gen_sock_stream
SOCK_STREAM-type sockets acceptor library.
Quick build how-to
Many of the tools (especially recent ones) are prepared to make a package (DEB and RPM).
- Clone the repository:
git clone http://dozzie.jarowit.net/code/cfgen.git
- Install tools for building packages
- for Debian: packages dpkg-dev, fakeroot, build-essential
- for Red Hat/CentOS: packages make, rpm-build
And possibly compilers (gcc, g++).
- Build a package:
- for Debian:
dpkg-buildpackage -b -uc
- for Red Hat/CentOS:
make srpm rpmbuild --rebuild *.src.rpm
- for Debian:
For original Trac start page, see WikiStartOld.
