My network contains an Apple Time Capsule as a nat router, an ethernet modem provided by my cable company Ziggo and devices such as laptops, that use the network.
A Soekris box I had lying around meets all requirements perfectly for a VPN-server. Here is how to set it up.

- Disaster: LVM Performance in Snapshot Mode – MySQL Performance Blog – In many cases I speculate how things should work based on what they do and in number of cases this lead me forming too good impression about technology and when running in completely unanticipated bug or performance bottleneck. This is exactly the case with LVM
Number of customers have reported the LVM gives very high penalty when snapshots are enabled (leave along if you try to run backup at this time) and so I decided to look into it.
- Netexpertise » Mysql Ultra-Fast Backup with LVM – It is generally good practice to respect the two following points when backing up databases. The backup has to be:
Consistency is easily achieved putting a read lock on all tables beforehands. However, this isn’t always applied, and WILL definately lead to a database integrity problem at some stage.
Once a lock has been set on the database, the backup has to be as quick as possible, all write instructions being held in the queue.

- mylvmbackup – mylvmbackup is a tool for quickly creating backups of a MySQL server's data files. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, creates a snapshot of the volume containing the MySQL data directory, and unlocks the tables again. The snapshot process takes only a small amount of time. When it is done, the server can continue normal operations, while the actual file backup proceeds.
