I am a developer of the modern web. And for more than a decade I am a rigorous practitioner of Open Source.
My day job at SUSE.com is hacking, operating and maintaining the Linux distribution development platform Open Build Service.

Unlike most monitoring tools that either focus on a small set of
statistics, format their output in only one way, run either
interatively or as a daemon but not both, collectl tries to do it all.
The Courier authentication library provides authentication services for
other Courier applications.
Courier-IMAP is a fast, scalable, enterprise IMAP server that uses
Maildirs. Many E-mail service providers use Courier-IMAP to easy handle
hundreds of thousands of mail accounts. With its built-in IMAP and POP3
aggregation proxy, Courier-IMAP has practically infinite horizontal
scalability. In a proxy configuration, a pool of Courier servers service
initial IMAP and POP3 connections from clients. They wait to receive the
client's log in request, look up the server that actually holds this mail
account's mailbox, and establish a proxy connection to the server, all in
a single, seamless process. Mail accounts can be moved between different
servers, to achieve optimum resource usage.
The only practical limitation on Courier-IMAP is available network and I/O
bandwidth. If you are new to Courier-IMAP, this may sound a bit
intimidating. But you do not need to tackle everything at once. Start by
taking small, easy steps. Your first step will be to set up a small
Courier-IMAP server, using it like any other traditional IMAP service, on
a single server. After you gain experience and become comfortable with
Courier, you can then begin exploring its advanced features.
This is the same IMAP server that's included in the Courier mail server,
but configured as a standalone IMAP server that can be used with other
mail servers - such as Qmail, Exim, or Postfix - that deliver to maildirs.
If you already have Courier installed, you do not need to download this
version. If you install this version, you must remove it if you later
install the entire Courier server.
Ding is a smart X Window System English-to-German dictionary. It works
with a local database file. For full functionality, agrep should be
ez-ipupdate is a small utility for updating your hostname for any of
the dynamic DNS services offered at:
* http://gnudip.cheapnet.net (GNUDip)
* http://www.dyn.ca (GNUDip)
fs-check checks file system sizes to see if they are getting too full.
It uses a configuration file that specifies the file systems to check,
e-mail contacts, trigger thresholds (percentage or amount used and
unused), and a report program to run. It includes fs-report, which
shows things like the largest files, the newest files, and core files.
It can be run from cron or as a daemon.
Gcal is a program for printing calendars. Gcal displays a calendar for
a month or a year, eternal holiday lists, and fixed date lists. The
program correctly omits the dates that were skipped when the current
Gregorian calendar replaced the earlier Julian calendar.
help2man is a script to create simple man pages from the --help and
--version output of programs.
Since most GNU documentation is now in info format, this provides a way
to generate a placeholder man page pointing to that resource while
still providing some useful information.
IMAPFilter is a mail filtering utility. It connects to remote mail
servers using the Internet Message Access Protocol (IMAP), sends
searching queries to the server and processes mailboxes based on the
results. It can be used to delete, copy, move, flag, etc. messages
residing in mailboxes at the same or different mail servers. The 4rev1
and 4 versions of the IMAP protocol are supported.
IMAPFilter uses the Lua programming language as a configuration and
The server part (package knockd) listens to all traffic on an ethernet
(or PPP) interface, looking for special "knock" sequences of port hits.
This client makes these port hits by sending a TCP (or UDP) packet to a
port on the server. This port does not need to be open. Since knockd
listens at the link-layer level, it sees all traffic even if it is
destined for a closed port. When the server detects a specific sequence
of port hits, it runs a command defined in its configuration file. This
can be used to open up holes in a firewall for quick access.
This library(libnldapx) dynamically links to OpenLDAP SDK(libldap) for
all basic SDK functionality and OpenSSL(libssl) present on platform and
provides the below mentioned featuears on top of it: SSL related
functionalities : Novell LDAP Extended Library provides the APIs to
setup the client SSL information which are not covered in the IETF
draft. These APIs implement the intent of the draft and simplify the
interface to the developer by providing functionalities like SSL bind ,
Interactive SSL. Schema functionalities : A set of APIs are
provided to modify (add, delete) and fetch the schema from an
eDirectory server over LDAP. LDAP Extensions : These are
the LDAP extensions which support the special features of Novell
eDirectory such as replication, partitioning and events. The
availability of these operations are subject to the specific
implementation of the LDAP Server .
This is an attempt at implementing a mailing list manager with the same
functionality as EZMLM, but with the MIT/X11 license and no mail server
Pdsh is a multithreaded remote shell client which executes commands on
multiple remote hosts in parallel. Pdsh can use several different
remote shell services, including standard "rsh", Kerberos IV, and ssh.
This is an implementation of ASN.1 types and codecs in Python programming
language. It has been first written to support particular protocol (SNMP) but
then generalized to be suitable for a wide range of protocols based on ASN.1
This module provides a nearly complete wrapping of the Oracle/Sleepycat C API
for the Database Environment, Database, Cursor, Log Cursor, Sequence and
Transaction objects, and each of these is exposed as a Python type in the
A secure pickle-like module. It support basic types (int, string, unicode,
tuple, list, dict, set,...), old and new-style classes (you need to register
the class for security), object cycles, and it can be extended to support
This module provides an additional log handler for Python's standard logging
package (PEP 282). This handler will write log events to log file which is
rotated when the log file reaches a certain size. Multiple processes can safely
write to the same log file concurrently.
Louie provides Python programmers with a straightforward way to dispatch
signals between objects in a wide variety of contexts. It is based on
PyDispatcher, which in turn was based on a highly-rated recipe in the Python
Changing the title is mostly useful in multi-process systems, for example when
a master process is forked: changing the children's title allows to identify
the task each process is busy with. The technique is used by PostgreSQL and
the OpenSSH Server for example.
The zc-lockfile package provides a basic portable implementation of
interprocess locks using lock files. The purpose if not specifically to
lock files, but to simply provide locks with an implementation based on
file-locking primitives. Of course, these locks could be used to mediate
access to other files
zdaemon is a Python package which provides APIs for managing
applications run as daemons. Its principal use to date has been to
manage the application server and storage server daemons for Zope / ZEO,
although it is not limited to running Python-based applications
