I often have a need for a fresh FreeBSD install, to host a server, or perhaps just experiment with. My usual solution is FreeBSD jails. However, I’ve recently gotten interested in Ansible and AWS. There are quite a few advantages to installing infra with AWS, however the one I’m most interested in is automating the…
A couple projects I’ve been working on have a need for a REPL style console. I had written a simple framework for creating REPL’s, which is open-sourced here.
I recently had a reason to need a TELNET server and couldn’t find a Java library that worked for me. After a weekend of hacking, I now have kTelnet, an Open-source, BSD-licensed, TELNET server.
I’ve recently become very interested in blockchain, and that, naturally led me to Ethereum and Bitcoin. From there, I got a little interested in online trading, but since I prefer not to have to think about trading, I started thinking about a trading bot. Part of the work I needed to do was write a…
I’ve been using FreeBSD jails for a while, and was looking for a simple way to create jail filesystems. After some reading, I came up with this simple script which creates full FreeBSD filesystems. The filesystem can then be used via jail.conf. #!/bin/bash JAILNAME=$1 echo “kjail “$1 JAIL_HOME=/tank/kjail/ FTP=http://ftp.freebsd.org/pub/FreeBSD/releases/amd64/11.1-RELEASE/ # # get packages # if…

I’ve been trying forever to get a mobile IPSec connection up between my OS X laptop and pfsense. Finally, thanks to this outstanding blog post, it works. I’m especially excited that it works with the default OS X and Android VPN clients. My pfsense config closely mirrors the one specified by Mike Murray pfsense…
I was recently asked to release some of my code to Maven Central, and therefore had to figure out how to do it. I’ve now released these khubla.com libraries: cBean Pragmatach antlr4test-maven-plugin OLMReader simpleIOC ParadoxReader The maven coordinates for each are documented on the github pages.
I have a number of disks in my FreeBSD box which exist only as backups of data. I prefer that they not be mounted all the time, but instead mounted on use. They are 2x internal SATA disks and an external USB3 disk. This blog post explains how they are set up to auto-mount….
Some printers, like the one I have (HP 8600 Pro), have “Print-to-Folder” capability. Unfortunately, I have no Windows server, only a FreeBSD box to print to. I can mount folders from the FreeBSD box on my MacBook.. if I can get files to scan there. So, to do that, I need a Samba…
