Peculiar problems with mc under byobu
I’m using byobu on a daily basis, but occasionally I also use mc (Midnight Commander). Midnight Commander is a terminal-based two-panel file manager as they became well known with Norton Commander. If you look for a similar solution for Windows, … Continue reading
So … PBXT or Aria?
I had changed the table storage engine format from MyISAM and InnoDB to PBXT for my blog and some other blogs I host. Little did I know. Of course WordPress will hide any and all errors from plain sight, so … Continue reading

XMPP S2S with Google and no TLS?
I’m running an ejabberd instance and it’s configured to use TLS in S2S (server to server) communications. It works perfectly fine with jabber.ccc.de, but Google’s server does not seem to like TLS. Very awkward. First I thought it may be … Continue reading

iptables flowchart
Just uploaded a flowchart that shows the order of packet processing in iptables to my downloads. You can find it here. There is the Visio file from which I created it in the same folder, just in case you want … Continue reading

Dieser Beitrag wurde im Original am 10.3. um 3:21 (UTC, also 4:21 dt. Zeit) eingestellt. … Continue reading

WordPress/twentyten header image
Had some trouble with the built-in twentyten images. The header image is saved inside a serialized hash in the database complete with the protocol and server name as well as the blog home URI. The problem with this is if … Continue reading
Some changes to the blog
Despite the server change, which you may not even have noticed, I’m also blocking any and all login attempts, renamed the admin user name (some people were apparently trying to get in) and the administration area is entirely off limits. … Continue reading

Installing MariaDB on Debian 6 (Squeeze)
Had some trouble installing MariaDB on Debian 6. The system was pretty much a vanilla Lenny (hadn’t used it much that’s why) upgraded to Squeeze only one week ago – and I wanted to install MariaDB instead of MySQL. This … Continue reading

Ernsthaft?
Plagiatsvorwurf gegen Guttenberg? Hat Deutschland plötzlich keine anderen Probleme mehr? Ja liebe deutsche Medienvertreter, seid ihr alle bescheuert? Und daß ein Doktortitel schmückt, wie Frau Slomka im ersten (!) Beitrag des Abends (2011-02-16) meinte, würde ich durchaus nicht so stehen … Continue reading

Irgendwas ist immer
Nach der heute-Sendung vom 2011-01-26 habe ich das Gefühl, daß es nicht so sehr um ein spezielles Problem wie Zensursulas Steckenpferd KiPo geht, sondern darum irgendwie die Infrastruktur für Internetzensur einzuführen – egal wie. 🙄 Da wird von einer diffusen … Continue reading
