Hello, In this rant, we'll install X software to Y system. You are here because you are a bit desperate finding the right package you need. Maybe the software and/or the system is a bit old. Let's start! First, download the software here: software.tar.gz Yes you saw damn right, a big blue TARBALL. You might not care about your system's file integrity and be a moron to not to think about that COMPILING thing!

New distros with cool ideas always amaze me. Too bad we generally have new shiny debuntu based software collections only. Bedrock is a different one. Here is a quote from official website: If one would like a rock-solid stable base (for example, from Debian or a RHEL clone) yet still have easy access to cutting-edge packages (from, say, Arch Linux), automate compiling packages with Gentoo's portage, and ensure that software aimed only for the ever popular Ubuntu will run smoothly - all at the same time, in the same distribution - Bedrock Linux will provide a means to achieve this.

Scripting under different unices is a bit painful. Especially if you have a completely mixed environment with plenty of obsolete systems in it. I was trying to get md5sum of something quickly. Here is the result: Sure, you can use md5sum command on every system if you install it, but this seems like the most painless way. Still failing on some old Solaris (like 8/9) but luckily I can skip those :)

Moved blog

My VPS on Contabo started to act funny, probably they overloaded their KVM hosts. I started to see messages like "[27941.674540] sh (9100): drop_caches: 3" on dmesg (totally not cool bro). So I've switched to DigitalOcean. Thanks to systemd-nspawn, moving entire system was really easy: rsync one big data file, mount it and start the container.

Seems like only reasonable way to use "dbx" tool (like dbx -a PID and issuing proc rlimit inside attached dbx). But somehow everyone just "quit"s dbx and sending SIGTRAP to process. Only if there is a way that you can "detach" before. Maybe this is new to AIX (probably came with 6, I'm still a rookie on AIXland) but it seems possible with "detach" command in dbx.

If you tried this topic and didn't help, you're probably using gentoo. I came across this bug with ~5.3.1. Stracing gave me following sequence: What the hell? Looking for kde pam module and skips right to "other", which denies auth without a question. If you have the same problem, try symlinking: ln -s /etc/pam.d/system-auth /etc/pam.d/kde

I've discovered systemd added a container utility called systemd-nspawn. It's basically chroot on steroids. (No, don't think Docker) I decided to give it a shot even they don't consider it stable yet. I tried to implement encryption a bit. Data normally sitting duck on bare-metal unencrypted servers (mainly because encryption seems hard or you trust your data center & country). If someone reboots the server and adds "rescue" to grub kernel line, (s)he will get a root user prompt, bye to personal/commercial sensitive info!

Drop the Dropbox

I've closed my Dropbox account (you might guess the motive behind it) and migrated my files to my fresh-installed OwnCloud 7. Configuring owncloud is still kind of pita. Here is the configuration file for Nginx/PHP-fpm virtualhost. Also follow this documentation to prevent bruteforce attacks to owncloud.

Couldn't find an easy & reliable way to check if memcached is running (for HA tools). Current check scripts on the net are generally stalling when memcached hits to maximum connections. So I wrote a dirty script that timeouts after 1 second on unsuccesful try. It's ugly but you get the idea. Why if ? Because my version of netcat wasn't exiting with correct error status on timeout for some reason.
