Somehow I’ve only just found out about ‘qshape’. It’s a nice little tool to help show what’s going on, on a postfix based mail server. You can summarise by sender (-s) and choose the queue …. which is a bit easier than trying to spot patterns in the ‘mailq’ output.

I needed a variant of Squid which supported transparent SSL interception (i.e via iptables redirection) so I could log outgoing HTTPS requests without the client being aware. The stock wheezy variant doesn’t support SSL (see : Debian Bug Report). Even after recompiling Wheezy’s squid3 it didn’t seem to work (perhaps my stupidity) so I ended… Continue reading Squid 3.4.x for with transparent ssl proxying/support for Debian Wheezy.

Virtualbox 4.2 VM autostart on Debian Squeeze & Wheezy
One new feature of VirtualBox 4.2 is that it has support for auto-starting vm’s on bootup of the host server (via init etc). This means I can remove my hackish ‘su – vbox -c “VBoxHeadless –startvm VMName &”‘ additions in /etc/rc.local, and the VM’s will also hopefully be terminated gracefully on shutdown.

Migrating an ext3 filesystem to ext4 (Debian Squeeze)
Interestingly (well, perhaps not really) this is very easy. In my case, I’m hoping that the migration will lead to faster fsck times (currently it’s taking about an hour, which is somewhat excessive, each time the server crashes for whatever reason). In my case, the filesystem is /dev/md0 and mounted at /home – change the… Continue reading Migrating an ext3 filesystem to ext4 (Debian Squeeze)
