New version of xmlrpcd is out. This version contains bug fixes for running xmlrpcd and xmlrpcaller under newer Debians and Red Hats/CentOSes.
new application: yumbootstrap
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.
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.
New version of cfgen is out. Added possibility of defining variables for all hosts and command line option for parameters inspection.
Home page for new tool was added: cfauditdump.
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).

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.
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.
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.
Network flow monitor. Displays traffic summaries for flows, which are defined by BPF filters.
You can think of this being similar iftop.
TODO: be more specific about munc.
The Right Way(tm) of doing rsync over SSL. Uses stunnel 4.x.
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.
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.
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.
Chroot installer for distributions that use Yum (mainly Red Hat, CentOS and Fedora). As the name suggests, it's a RPM clone for debootstrap.
Module aiming at keeping configuration coming from different sources: configuration files and command line. API influenced by Log::Log4perl.
Module for structured logging. Log::Message::JSON is basically a hash(ref) that magically stringifies to JSON when necessary.
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.
Nothing published yet
Helper library making starting Erlang code as a daemon way easier.
XML-RPC client and server library.
Simple XML-RPC daemon in Erlang.
INI-like file loader library.
SOCK_STREAM-type sockets acceptor library.
Low-dependency Server-Sent Events server side implementation.
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:
