Services
This server provides the following services to the public.
AUR repository
See https://build.kilabit.info for more information.
DNS server
The DNS server is run using rescached on the following port,
-
DNS over UDP at port 53,
-
DNS over HTTPS at "https://kilabit.info/dns-query",
-
DNS over TLS at port 443.
Check the IP address using dig or ping to domain kilabit.info.
Some stranger abuse the UDP port 53, so the service may be get blocked
at some point.
We use CloudFlare DNS as parent name servers.
Projects
asciidoctor-go
The asciidoctor-go is the Go module to parse the AsciiDoc markup and convert it into HTML5.
awwan
awwan is configuration management software, infrastructure as file and
directory layout.
In other words, awwan is command-line interface to execute multiple lines
of command in the local or remote server using SSH.
Do you have a collection of shell scripts to manage one more similar server? Do you ever want to execute only part of your shell script in remote server? Are you get tired with learning others syntax and tools for provisioning your own server, while you need is a handful knowledge of shell script?
If yes, awwan is the right tools for you.
beku (deprecated in favor of Go module)
Beku is command line program to manage packages in user’s
environment (GOPATH or vendor directory).
Beku provide syntax like pacman.
This program exists long before before godep or Go module exist and stable.
ciigo
ciigo is a program to write static web server with embedded files
using asciidoc markup language.
This site and golang-id.org is written with ciigo as framework.
golang-id.org
This website is my second contribution to Go community. Its goal is not only to provide help, through translation, for Indonesian to learn more about Go but also to provide an ecosystem for Indonesian Go community, for example, vlog and blog in Indonesian language, and sharing open source works written in Go. The website is freshly launched, they are still more works to be done, though.
gorankusu
gorankusu is a Go module that provide HTTP service with web user interface
for testing HTTP endpoints (like Postman) and for load testing.
For the load testing we use
vegeta
as the backend.
haminer
haminer is a library and program to parse and forward HAProxy logs to InfluxDB for mining HTTP requests.
karajo
karajo is the library and program to implement HTTP workers and manager similar to AppEngine cron. karajo has the web user interface for monitoring the jobs.
libvos (unmaintained)

Current features included Buffer module, File module, Socket module, reading and writing INI file format, FTP (server and client) module, DNS module, and Oracle Client Interface module.
pakakeh.go

The most outstanding packages are WebSocket (server and client), DNS (server

The idea is to minimize network traffic for outside DNS queries and to manage local zone files. The first implementation was written in C++ and then re-written using Go.
tour.golang-id.org
The tour.golang-id.org is translation of their original website tour.golang.org to Indonesian language, to help newcomers learning Go programming language. This is my first contribution to Go community.
vos (unmaintained)
Vos is a program to process formatted data, i.e. CSV data. Vos is designed to process a large input file, a file where their size is larger than the size of memory, and can be tuned to adapt with machine environment. Vos can do sorting, formatting, filtering, and join, by reading input file and its configuration script. Its written in C.

Research on SSH with 2FA. In this journal, we review several options to manage SSH authorization beyond using public keys, possibly also enabling 2FA, using Time-Based One-Time Password (TOTP). Some of the alternatives that we will review are Google Cloud OS Login, Smallstep, Teleport, and google-authenticator-libpam.
Using systemd mkosi for development (round 2). Continuing previous attempt, in this journal we take different path.
Using systemd mkosi for
development.
In this journal, I will take a notes on my journey learning and using
mkosi as part of integration tests for developing
awwan.
The goal is that when I run make on awwan repository, it will create
and run a container using systemd-nspawn(1) with SSH server running, and
run all tests inside the container.
