Not only that it's less expensive, it also has the advantage that someone else than me takes care of the hardware.</p><p>The new system is a 64-bit Linux, even though the current physical machine has only 2 GB of RAM, but I'm afraid that 32-bit Linux systems will cease to be available in the foreseeable future. This change required significantly more work than just restoring from the backup. I'd like to apologize for the longer downtime caused by it.</p><p>No e-mail arrived before the crash should be lost, however some e-mails may have bounced during the downtime. Everything should be working as before now, I hope. If not, please drop me a note.</p><p>The groupware / webmail system has been upgraded to the latest version as well to close some potential security (XSS) issues.</p>Maschin kaputt2010-10-15T17:55:00+00:00o'wolfhttps://woelfisch.de/blog/author/owolfhttps://woelfisch.de/blog/maschin-kaputt<p>Just a quick heads-up: My co-located machine martes.yaina.de keeps crashing after a reboot. I'm going to move to a rental machine ASAP (on Monday at earliest,) but it will take a couple of days until everything is working again. The current plan is:<ul><li>Retrieve the broken machine from the data center</li><li>Recover the harddisk</li><li>Set up the base system on the new machine</li><li>Set up DNS (Secondaries: I'll send you an e-mail with the new IP number)</li><li>Restore e-mails</li><li>Set up e-mail services</li><li>Restore web services</li><li>Restore everything else</li></ul>I'll send an update to all users as soon as service is back to normal.</p><p>I'll spare everyone my rant about the reliability of PC hardware. On the other hand, the broken machine served well for at least eight years, which is an eternity for this kind of technology.</p>About eating your own dog food2009-04-16T11:39:00+00:00o'wolfhttps://woelfisch.de/blog/author/owolfhttps://woelfisch.de/blog/about-eating-your-own-dog-food<p>I've successfully updated my machine located at the data centre from openSUSE 11.0 to 11.1 via a remote SSH connection and "<kbd>zypper dup</kbd>" yesterday. Contrary to my previous experiences with online upgrades, only minor obstacles were encountered:<br/><ul><li>Jabberd, the only package from OBS, got rebuilt between downloading the meta data and the package itself</li><br/><li>Zypper somehow got confused by blank characters in repo locations midway through the update (simply restarting zypper helped)</li><br/><li>I had to copy back my manually edited postfix configuration as it was replaced by the generic one from the RPM</li><br/><li>Tomcat6 startup scripts missing JAVA_HOME</li></ul><br/>Just two hours of work (mainly observing zypper working and checking functionality), no serious breakage, no trip to the data centre, no manual update of half of the packages. I'm truly impressed.</p>
