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.
Minor cronbuilder release, incorporating new command line option helping in source repository migration.
cfgen v1.0 and xmlrpcd v1.0
New version of cronbuilder is out. Added support for multiple instances on the same repository, fixed Subversion support and improved support for repositories accessible via SSL.
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).

They 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 gitweb.
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.
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.
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).
Little daemon that collects OpenVZ statistics in guest system and pushes them to collectd.
Requires that collectd has UnixSock plugin enabled.
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.
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:
