Hetzner Cloud: LUKS remote unlock on Debian

I recently decided to migrate my mailserver away from the (old) Uberspace 6 to a new, self administrated machine. Uberspace has been great but over time I demanded more features than they offer. Due to the fact that I want to keep the mailserver for my primary mail address separated from my main server, I once again compared multiple virtual server/cloud server hosters. I decided to give Hetzners new Cloud Server a go as you can use custom images to build the OS (Debian is the distribution of my choice) as you like.

Spacewalk: Failed channel syncs because of duplicate packages

A brief summary: I’m working with Spacewalk for three years now, from version 2.4 on. We manage about 350 systems, 30+ channels, 50+ repositories and 105.000+ packages. We import new packages and errata on a daily basis, roll out critical patches to stage systems automatically and do weekly/monthly patchdays on productive systems exclusively via Spacewalk. Lately the periodic syncs of our CentOS 6 x86_64 channel failed on every run. New packages stayed in the queue and could not be rolled out to our systems.

Quick Info: VMware Workstation Netzwerk funktioniert nicht

Ich habe kürzlich meine VMware Workstation auf eine neue Hostmaschine umgezogen und seitdem funktionierten weder die vmnet Interfaces noch sonst irgendein Netzwerk Service von VMware. Mittels vmware-network -status lässt sich der aktuelle Zustand der virtuellen NICs und der Netservices überprüfen. Bei mir kam Bridge networking on vmnet0 is not running DHCP service on vmnet1 is not running Hostonly virtual adapter on vmnet1 is disabled DHCP service on vmnet8 is not running NAT service on vmnet8 is not running Hostonly virtual adapter on vmnet8 is disabled Some/All of the configured services are not running was ich versuchte mit vmware-network -start zu beheben.

ShareX Alternative für GNU/Linux

Eins der wenigen Programme die ich unter Debian vermisse ist ShareX welches nach wie vor keinen Linux Support bekommen hat. Viele schlagen Shutter als Alternative vor aber wenn man mal ehrlich ist kommt es nicht mal ansatzweise an ShareX ran… Bisher eher unbekannt scheint hingegen Screencloud zu sein, obwohl es genau das tut was ich brauche. Es erlaubt Screenshots von Programmen, dem kompletten Bildschirm oder frei gewählten Bereichen zu machen und sie danach in die Zwischenablage zu kopieren oder zu online Diensten hochzuladen.
