Yes, it’s a bit juvenile, but I had a sudden urge to know what was at the coolest IP address on the Internet: 69.69.69.69
wg@wg-laptop:~$ host 69.69.69.69 69.69.69.69.in-addr.arpa domain name pointer the-coolest-ip-on-the-net.com.
I shouldn’t have asked :). It appears to be owned by “Embarq Services“. Perhaps equally as cool is 42.42.42.42, but that 42.0.0.0/8 seems to be reserved by IANA. Bummer.
For those of us early adopters (well, it’s not so early any more…) who have jumped on the IPv6 train, Planet SysAdmin is now available via IPv6! Thanks go to SixXS for providing the tunnel, although it would have been nicer if my provider was able to give me native IPv6, sigh.
It’s promising that after being live for less than a couple of hours, I’ve already spied several (at least 4) IPv6 hosts in the access logs 
I have just installed Cacti on a new FreeBSD 6.3 machine that I’ve been playing with, and the latest version from ports seems to be broken, displaying the error “Invalid PHP_SELF Path” when I browse to it with a web browser.
A Google search reveals that it seems to be a common problem. This post on the Cacti forums proposes a temporary fix, which I have implemented and seems to work without any problems. It may expose your cacti installation to security problems, but I haven’t looked in to this, and I suspect that most Cacti installations (like mine) are protected by htaccess authentication anyway.
The fix:
In the file /usr/local/share/cacti/includes/global.php, comment out (by prepending //), or delete line 113:
if (!((is_file($_SERVER["SCRIPT_FILENAME"])) && (substr_count($_SERVER["SCRIPT_FILENAME"], $_SERVER["PHP_SELF"])))) {And replace it with this one:
if (!((is_file($_SERVER["SCRIPT_FILENAME"])))) {
Hopefully a new version of Cacti is out soon that fixes this problem.
I needed to read data from a USB connected hard disk formatted as UFS by FreeBSD 6.x on an Ubuntu Linux system. As it turns out, it was easier than I expected, as Ubuntu (well, Ubuntu Server at least) has built in read-only support for UFS file systems.
$ dmesg |grep "bsd:" [ 31.178307] sda1: <bsd: > $ sudo mkdir /mnt/ufsdisk $ sudo mount -t ufs -r -o ufstype=ufs2 /dev/sda1 /mnt/ufsdisk $
Check with mount to confirm that this has worked:
$ mount [..] /dev/sda1 on /mnt/backupdisk type ufs (ro,ufstype=ufs2) $
All done.
That’s right. The newly elected Labor government has decided that they should protect children from pornography, violence, and hate material on the Internet by imposing mandatory filtering of Internet traffic at the ISP level. Such filtering would be based on a black list decided by ACMA bureaucrats (who don’t yet exist and haven’t been requested by the department), based on lists provided by religious and family groups. Such a plan is impractical, expensive, invasive, trivial to circumvent, and ineffective. I’m not even going to begin to go in to the technical difficulties.
Well it’s been a while since I updated, I guess I’ve been busy! But anyway, since my last update on Planet SysAdmin, here are the blogs that I’ve added to the aggregator:

Hope you all are having a great Holiday period. I know I’m certainly enjoying the time off work :-).
Update (30-Dec): Today, I also added the blog of Erik Dyskant to Planet SysAdmin
I recently bought a new notebook (Sony TZ27GN, which is awesome by the way :D), and something that immediately annoyed me is the sensitivity of the touchpad — so many times I would accidentally “click” while dragging across the touchpad.
So I disabled this feature. Here’s how, running Ubuntu Linux:
I’m in the USA! I’ll be in Costa Mesa CA until Monday, North Houston TX from Monday until Wednesday, and then back in Costa Mesa Wednesday night until Saturday night, when I return home to Perth, Australia.
Beer/food/coffee/etc, any one?
