Searching for the old Compaq nof1.exe utility (A utility to change a Compaq Desktop to boot without a keyboard attached) I came across the following tip:
1. Set a power on password (under security in the BIOS settings)
2. Go back into security menu and select the new item that appears just below power on password, it’s called password settings or suchlike.
3. Enable Network server mode
Your machine will now boot happily without a keyboard, and in case you wonder also without asking for the password you just set.
The keyboard, if anyone does plug one in, is disabled except during power up when you can still press F10 for setup. Doing so will then lead to a prompt for the password.
I tried the above tip and it works perfectly, for correctness: the “password settings” option in the BIOS is called password options instead of “password settings”.

One of the chores I dislike most is cleaning up and clearing out the log files in my Rails applications. On some of my higher profile sites, I get a lot of spiders probing my applications for security holes. They don’t succeed (knock on wood) but they do fill up my log files with errors.
I finally decided to get smart and get lazy (the two best traits a programmer can have), and I set up automatic log rotation on all of my Rails applications. The idea behind log rotation is simple: make a back up of the current log file, continue logging into a new or cleared log file, and discard log files that are older than a certain date.
Your webserver probably already rotates its own log files. For Apache, they are probably located in /etc/httpd/logs and they are probably rotated weekly. These logs store everything Apache does. Simple webserver stats and traffic analysis tools make use of these log files to show who visits a site when and what pages are viewed.
While it is possible to configure your Rails application to log to your Apache log files, I do not think it is a good practice. It’s much better to give each Rails application its own log file—it will be easier to find important Rails errors, it will keep your Apache logs cleaner and Rails is set up to keep its own logs by default. Fortunately, on a Linux server the built-in logrotate program will make the process super-easy. After the jump, I’ll walk you through the steps to get it set up.

On this website I found the following tip:
Cloning a FreeBSD system
Simplifying by assuming a single partition, a secure network, and ucspi-tcp already installed on ORIG…
Install fresh hard disk in CLONE, and boot from a FreeBSD rescue floppy.
Rather than installing, go to the “configure” submenu and do “fdisk” and “slice.” Use W Q instead of just Q to quit each one. Install a boot manager just as if you were building a new system.
Go back to the main menu and choose “fixit,” then “live filesystem on CD-ROM.”

In order to get a IPV6 tunnel working with a Thomson Speedtouch 500 series ADSL modem like the Speedtouch 510. You will have to set the following option in your modem:
(connect via telnet)
=> nat unbind application IP6TO4 port=1[ENTER]
Other IPv6 tunneling tips can be found on this website.
