Software

Unless otherwise mentioned, all of this software builds and runs under every flavour of Unix - and only Unix.

Current, released, maintained software

skalibs
A set of general-purpose C programming libraries. You need this first: all the other software in this list depends on it.
execline
A small scripting language, to be used in place of a shell in non-interactive scripts.
s6
skarnet.org's small & secure supervision software suite. Comes with an ultra-fast init replacement, process management tools, an asynchronous locking library, and more.
s6-rc
A complete service manager for s6 systems.
s6-portable-utils
Tiny portable generic utilities.
s6-linux-utils
Tiny Linux-specific utilities.
s6-dns
Good, usable DNS client libraries (synchronous and asynchronous), and command-line DNS client utilities.
s6-networking
UCSPI Unix and TCP tools, a SSL/TLS tunnel, access control tools, and network time management utilities.
s6-linux-init
A tool to automate the creation of suitable stage 1 init binaries for s6-based Linux systems.
lh-bootstrap
A set of scripts to build a disk image (for QEMU, for instance), running s6 and s6-rc, with an Internet connection.
sdnotify-wrapper
A wrapper for daemons so they can use the simple readiness notification mechanism recommended with s6 and still work under systemd with proper readiness notification, without having to use the sd_notify() interface themselves.
mdevd
A Linux kernel event manager daemon (like udevd) that understands the mdev configuration file format and does not fork.
utmps
A secure utmp/wtmp implementation.
nsss
A small and statically linkable alternative to Name Service Switch.

Software listed here might disappear at any moment. This list only exists for transitional purposes.

minidentd
A small ident server. (Now included in s6-networking.)
skadns
An asynchronous DNS client library. (Now included in s6-dns.)
conn-tools
A collection of simple tools to handle reliable connections between processes. (Replaced with s6-networking.)
skaembutils
Tiny portable utilities that I found missing from the embutils. (Replaced with s6-portable-utils.)
minutils
Tiny Linux-specific utilities that I found missing from the embutils. (Replaced with s6-linux-utils.)
minnotify
A client and a server to implement general-purpose notification over the network. (Useless now that execline exists: can be replaced by trivial execline scripts.)
symtools
A collection of simple tools to handle symlinks gracefully. (Now included in s6-portable-utils.)
ucspilogd
A very, very small syslogd replacement. (Now included in s6.)
The salted project has been abandoned. Instead, TLS/SSL support has been added to s6-networking: with the BearSSL backend, it is possible to offer this support while still using extremely few resources.

David Madore's Book of Infinity, as a single C file suitable for compilation with skalibs.
The Book of Infinity is a web robot trap.
David Madore's superstrip, as a single C file suitable for compilation with skalibs.
superstrip is a very aggressive ELF stripping utility.
djbdns-fwdzone
A patch to djbdns to allow dnscache to perform resolution or forwarding according to the query zone.
nistp224-buffer
A patch to nistp224 to make the main binaries use djb's buffer library instead of stdio.
qmail-qmtproutes
An add-on to Russell Nelson's qmail-1.03-qmtpc patch for qmail. This one allows you to send mail via QMTP using a qmtproutes file.

Current versions of the packages use a standard ./configure && make && sudo make install installation scheme. Older versions use an ad-hoc installation scheme; if you need to install an older version and need help, please contact the skaware mailing-list.
