NIC teaming on Debian Etch and Lenny

There are plenty of HOWTOs on so called NIC teaming or NIC bonding for Debian, but of the ones I’ve seen, they’ve all missed some rather important bits. Below is the method I personally found to work reliably: apt-get install ifenslave echo "bonding" >> /etc/modules…

Reconstructing heavily damaged hard drives

[EDIT: Hey guys, thanks for the feedback! Someone over at virtuallyhyper.com has an awesome write up that deals with SD cards specifically (but is highly relevant to hard drives too), with a set of much improved and updated scripts. I’d strongly recommend taking a look…

Full, recoverable, DVD server backups

If you’re responsible for one or more Linux servers, (they provide packages for Linux distributions only, but it may be easily ported to other Unixes) you may be interested in the lesser known tool MondoRescue. It’s essentially nothing more (but it is a lot!) than…

Epson AL-C1100 efficiency

Today we discovered that Epson’s wonderfully affordable colour LaserJet printer (the AL-C1100, networked) isn’t actually as efficient as they claim. Epson are quick to promote the number of pages per cartridge this bessy can do (which I agree, is very good for a colour laser)…

gpart

So we’ve all done it at some point. Bye bye beautiful partition table. Bye bye 20 user’s worth of mail. Bye bye rest of my weekend doing anything enjoyable. I just had to blog this, I was that impressed! gpart scans your hard drive for…

Daemon permissions and posix_setgid()

posix_setgid only sets the primary group for the process.  So make sure the group permissions you’re relying is a single group, who’s GID is set in /etc/passwd. Took me over an hour to trace that bug down today.

Reverse proxying with FreeBSD

Being the geek I am, I have a nasty habbit of setting something up and then thinking “OK, so it runs, but what would happen if…“, and I then go on to think about the most unlikely, impossible, worse-case senario and try to figure a…

Moving a Linux install

Continuing with the theme of broken backup servers (oh boy am I having fun this week) I decided it may be worth giving a short explanation of how to clone or move a Linux install from one hard drive to another (note I’m not talking…

Linux and large hard drives

I just finished rebuilding the backup server, and I discovered something new about Linux which I didn’t know (although I did assume it was possible). I’d tried googling for the answer to this question without avail, so I’ve blogged it here to hopefully answer the…
