Configuring a Debian exim server for internet delivery

I wanted an Exim server which could send mail on its own without the use of another SMTP server. Read More »

Customizing displayed headers in Mozilla Thunderbird

For some reason, the new Thunderbird 3 thought it was useful to show me the content_encoding header per default, below the addressee and stuff. This header had such a long name that it disrupted the layout. Luckily, you can change what headers it displays by editing "mailnews.headers.extraExpandedHeaders" in the configuration editor.

Scroll in windows under mouse pointer in Windows

In Windows, you have to click on windows, and even window-panes, before the scrollwheel works there. With mousewiz, you can alter that behaviour, and make it like most Linux Desktops, where you scroll in the window/pane that is under the cursor.

Aligning partitions with RAID and LVM on drives with 4 kB sectors

Hard disks are being released that abandon the long-established standard of 512 byte sectors. I just got two Western Digital WD15EARS ones, which uses 4 kB sectors. Western Digital Refers to this as "Advanced Format". This poses some serious problems. I will describe those, and what I did to 'solve' it. Read More »

I just got two Western Digital 1.5TB WD15EARS disks. This drive has a feature called intellipark, which parks the head after the disk is not used for a while. This is supposedly a power saving feature. But, as someone explains, it can also severely decrease the lifetime of your drive. Read More »

Upgrading Samba from Lenny-backports

For some reason, after upgrading to the Samba version from Lenny-backports I needed to support Windows 7 profiles, the workstations suffered from severe problems. The entire profile seemed to be read-only, even though they weren't on disk. I couldn't change any setting and reverting profile configuration from backups didn't help. In the end, the only thing that fixed it was recreating the user profile, both server and client side. This was an upgrade from 3.2.5 to 3.4.7. Read More »

Adding a virtual network interface on Debian

Preventing the creation of $RECYCLE.BIN on Samba shares by Windows 7

Windows 7 kept creating a $RECYCLE.BIN dir on the network share. This in itself is merely annoying, but there were also errors resulting from it. Whenever a file would be deleted, this message would appear (translated from dutch): "The recycle bin is damaged, do you want to delete the contents?" Everything froze until that question was answered. Read More »
