New features in open source ZFS

Since OpenSolaris got discontinued, the development of open source ZFS continues at the illumos project. The main contributors are the companies Delphix, Nexenta and Joyent. In this post I am going to sum up the main user-visible changes in ZFS since the start of illumos.

This is an updated version of the article originally posted on July 9, 2012. Continue reading

Facebook’s HipHop Virtual Machine in FreeBSD ports

Great news for PHP administrators and site architects – the Facebook’s HipHop Virtual Machine (HHVM) version 2.1 is now available in the FreeBSD ports tree. The port is available under lang/hiphop-php and is limited to the amd64 architecture.

HHVM is an open source virtual machine that can act as a standalone server that can run PHP sites. With it’s just-in-time compilation approach PHP sites receive a reasonable speedup.

Special thanks to vanilla@FreeBSD.org who has helped me making this port work. Our patches have been submitted to Facebook via GitHub. Continue reading

EuroBSDcon 2012 – Tuning ZFS on FreeBSD

This year’s EuroBSDcon took place at the Warsaw University of Technology on October 20-21. The conference was well organized with great keynote talks by Eric Allman and Kirk McKusick. My talk was titled “Tuning ZFS on FreeBSD” and based on my identically named article in the August issue of the BSD Magazine. I presented several do’s and don’ts and other findings and recommendations from my experience with the ZFS file system.

VX Connectbot passes 10000 user installs

I am nicely surprised that the user number of VX ConnectBot (Android SSH client) users keeps growing steadily. The app has been on Google Play since December, 2011. The total user installs (users that have tried the application) has passed the 10000 mark in June and active user installs (users that have the application installed) are now over 5000.

FreeBSD network configuration on Hetzner servers

Update: article updated 20.3.2013

My current dedicated server provider in Europe is the german company Hetzner. They support FreeBSD but use a non-standard network configuration. It is not very well documented how to properly configure network settings on FreeBSD to have a fully functional IPv4 and IPv6 network. In this article I am giving an example how to configure it properly just with the /etc/rc.conf file. Continue reading

VX ConnectBot

In my last article, I have introduced my new smartphone Sony Ericsson Xperia pro and mentioned the open source SSH client ConnectBot. It is a great application but it was by far not optimized for the hardware keyboard of my smartphone. I have also tried the alternative solution Irssiconnectbot, which was little better but still not really usable – important keys were missing.

So I decided to fork, add some features from Irssiconnectbot, add ssh agent from Roberto Tyley, fix several bugs, add some tweaks by myself and optimize for Sony Ericsson Xperia pro and Xperia mini pro. The new application is named VX ConnectBot. Continue reading

My new Android smartphone

My well-proven companion Nokia N810 used for remote administration of FreeBSD servers was getting old, slow and outdated. It was my mobile SSH device for the last 4 years (probably one of the best solutions at time of purchase). Unfortunately, it was lacking phone functions (Bluetooth and WiFi only).

So I decided to go for a new device. I needed a smartphone with a decent screen, a hardware keyboard and an acceptable operating system (I need a SSH client). There are not many devices with an acceptable hardware keyboard on the European market. After a long decision process I chose the Sony Ericsson Xperia pro and it am happy with my choice.
