Hanging network in XEN with bridging

This article is about a strange network problem occuring when used bridging in a XEN environment.
Symptoms

Some DomU is not reachable from the network anymore.

Endian 2.3 in Xen on Debian Lenny

This article is about setting up Endian 2.3 on a XEN machine without hardware virtualization (hvm).
We work in a shared office space. It’s none of those big anonymous spaces where you can rent in on a monthly basis, but it does not belong to us alone. We share it with p4930 (architects) and control-b (we [...]

Because of my latest studies about ZFS (a post will follow soon) i was very aware [...]

FastCGI for the Best, suPHP for the Rest

Wie jeder Shared-Hoster wurden wir auch mit folgender Frage konfrontiert: Wie lösen wir das PHP Problem ?
Was dieses Problem ist und warum man es nicht mit mod_php lösen kann wird schon genügend im Netz beschrieben .
Ich habe mich damals ziemlich schnell mit der mod_fastcgi + php-cgi angefreundet und es ist nun seit nunmehr 5 Monaten [...]

Aktuelles Dovecot in Debian

Wir setzen nun schon seit einiger Zeit Dovecot als IMAP und POP3 Server ein. Wir sind auch vollauf damit zufrieden .. nur nervt doch ein bischen, dass die Debian-Pakete immer Monate hinter der offiziellen Stable hinterher hinken.
Da ich aber inzwischen geübt mit dem Erstellen von eigenen .debs bin habe ich mir mal die Zeit genommen [...]
