This is a mini-HowTo on running Finit in an LXC system container. We
will be using a variant (external) of Buildroot, called NetBox to
create a squashfs (read-only) image for the root filesystem. Then we
will give the container a single writable directory from which it then
uses bind mount to emulate a full-blown system.
It is expected you have LXC installed and all the relevant build tools
needed to create the image. How to set that up is not covered by this
tutorial.
As a follow-up to my previous Buildroot mailing-list post about the
git format-patch and git send-email commands, this post covers how
to set up the latter.
I’m very pleased to announce Finit v4.2! It comes seven months
after the last release, v4.1, with a bunch of fixes and some new
features. See the release notes for details.
This is a blog post about Finit. Each post is concluded with a video
summarizing the topic. The impatient reader can scroll down to the
video.
Most non-trivial systems require dependency tracking between services.
Not only does it help ensure correct operation, it is also an enabler
for starting services in parallel. Less known, but just as important,
is handling dependencies at system reconfiguration.
Micro Tetris — one of the smallest Tetris implementations in the world! Utilizing only ANSI escape sequences to draw the board, no external library dependencys other than a standard C-library, like uClibc or musl libc. Hence, it is very suitable for small embedded devices in need of an easter egg ;-)
The game is based on a 1989 International Obfuscated C Code Contest (IOCCC) entry made by John Tromp.
This post details how to set up cgit with Merecat httpd. It
began as a GitHub issue report by Mr Alok G. Singh, who had run
into problems setting it up, and ended up as a HowTo.
This is a HowTo for setting up ikiwiki with Merecat httpd.
First install ikiwiki
$ sudo apt install ikiwiki libcgi-session-perl libcgi-formbuilder-perl Follow the steps to setup a new Wiki or Blog. In this example we set up a wiki in our ~/public_html:
$ ikiwiki --setup /etc/ikiwiki/auto.setup ... Successfully set up wiki: url: http://localhost/~jocke/wiki srcdir: ~/wiki destdir: ~/public_html/wiki repository: ~/wiki.git To modify settings, edit ~/home.setup and then run:
$ ikiwiki --setup ~/home.
mrouted is an implementation of the IPv4 multicast routing protocol DVMRP, RFC 1075. It is capable of turning a UNIX workstation, or Linux device, into a multicast router with tunneling support.
Tunneling may be required to cross non-multicast-aware routers.
The Distantance Vector Multicast Routing Protocol (DVMRP), derived from RIP, is suitable for smaller/dense networks. It employs the “flood and prune” method, where multicast is flooded until neighboring routers opt out from unwanted multicast groups.
Every so often someone new to Open Source shows up on GitHub or in my
inbox with a question like:
“I just downloaded your software, what’s next?”
“It doesn’t build on my system, can you help?”
“How can I adapt it to my own use-case?”
“Could the build system be improved?”
These are all good questions, and this HowTo tries to answer the most
common ones up front.
0. Short Version
Download a versioned archive from the project’s Releases page
Extract archive for v1.2.3 and change to its directory, cd archive-1.2.3/
./configure --help, or use something like the following …
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var && make && sudo make install
Some of my projects are also available in Debian/Ubuntu/FreeBSD. If
you installed one from there, please report bugs to them first, they
may carry their own patches.
# # smcroute.conf example # # The configuration file supports joining multicast groups, to use # Layer-2 signaling so that switches and routers open up multicast # traffic to your interfaces. Leave is not supported, remove the # mgroup and SIGHUP your daemon, or send a specific leave command. # # NOTE: Use of the mgroup command should be avoided if possible. # Instead configure "router ports" or similar on the switches # or bridges on your LAN.
