This is similar to the previous disk quota exploit I mentioned, except that this time an attacker can exploit the inode quota on the disk. This quota defines how many files user can use/store on a disk/partition. If there is no capping on this value, a user process can occupy all the inodes available on […]

Checking the Disk Quota #1
This is again similar to the others above, except that this time an attacker can exploit the disk quota. This quota defines how much space a user can use/store on a disk/partition. If there is no capping on this value, a user process can try to fill up the disk space available in the system, […]
Checking the Memory Quota
This is somehow similar to the one above, except that this time an attacker can exploit the memory quota. This quota defines how much memory a user process can allocate at a time. If there is no capping on this value, a user process can try to allocate all the memory available in the system […]
Linux Hacks — Process Quota
One way an attacker might try to crash your machine is to exploit the process quota — more specifically to exploit the fact that a process quota is not set. The process quota defines an upper limit for the number of processes a user can run at any moment in time. If this is not, […]

Personally I can’t! 🙂 And if you do, you might have contemplated using the Autocomplete Plugin for SquirrelMail, which does […]
Customizing Squirrel Mail Login Page
For those of you who are using SquirrelMail, you might have noticed that it looks a bit well, let’s just say amateurish 🙂 That doesn’t go to say it isn’t a good package! (I personally love it and I think it does a pretty good job — hence my additions to this software.) However, as […]
Server Migration
Some of you might have noticed, some might not, but I finally got off my arse to migrate my liviutudor.com domain to a proper hosting package. Gone are the days where I had 2 servers stuck under my desk at home — as much as I had fun X11-ing into my Linux boxes and adding […]
System Update
For the less geeky of you who haven’t figured it out by now, there’s been quite a few changes recently on my website(s): First of all, my advertising/banners are now served via a fresh implementation of OpenX — and I can’t begin to tell you how much easier is to normalize <script> tags and <iframe> […]
