  • Booting once-only – GNU GRUB Manual 0.97 – You can teach GRUB to boot an entry only at next boot time. Suppose that your have an old kernel old_kernel and a new kernel new_kernel. You know that old_kernel can boot your system correctly, and you want to test new_kernel.<br />
    To ensure that your system will go back to the old kernel even if the new kernel fails (e.g. it panics), you can specify that GRUB should try the new kernel only once and boot the old kernel after that.<br />

  • How to: Ubuntu PHP Remove Suhosin – […] One of my projects for the "holidays" is moving one of my servers from Gentoo to Ubuntu. During planning for this, I noticed that the Ubuntu version of PHP5 includes Suhosin. That's a problem.<br />
    The problem with Suhosin is that it's designed to stop sloppy applications from doing bad things. I'm sure it does a reasonable job of that, but in the process it can interfere with good applications (see examples for Joomla). Since I'm in the business of writing good applications, Suhosin is a bad idea. Worse yet, it can provide a false sense of security, since it can't deal with anything except typical PHP errors. As far as I'm concerned, this class of "security blanket" provides false comfort and is no replacement for auditing and testing.<br />

  • Troubleshoot Connections through the PIX and ASA – Cisco Systems – This document provides troubleshooting ideas and suggestions for when you use the Cisco ASA 5500 Series Adaptive Security Appliance (ASA) and the Cisco PIX 500 Series Security Appliance. More often than not, when applications or network sources break or are not available, firewalls (PIX or ASA) tend to be a primary target and blamed as the cause of outages. With some testing on the ASA or PIX, an administrator can determine whether or not the ASA/PIX causes the problem.

  • ASCII Paint – Enjoy drawing and viewing some crazy ascii art. Output can be in C/C++/Java style comments Assembly comments, or the million other languages that support the # – sign comments.

    Use the buttons to change what your cursor does. Hit whatever key on the keyboard you want to be drawing with.

    If you make something cool, share it! It will be added to our database of ascii art, which will become much more accessible as time goes on. Right now you can only see random Ascii Art, but there will be a voting system shortly.

  • Scapy – Scapy is a powerful interactive packet manipulation program. It is able to forge or decode packets of a wide number of protocols, send them on the wire, capture them, match requests and replies, and much more. It can easily handle most classical tasks like scanning, tracerouting, probing, unit tests, attacks or network discovery (it can replace hping, 85% of nmap, arpspoof, arp-sk, arping, tcpdump, tethereal, p0f, etc.). It also performs very well at a lot of other specific tasks that most other tools can't handle, like sending invalid frames, injecting your own 802.11 frames, combining technics (VLAN hopping+ARP cache poisoning, VOIP decoding on WEP encrypted channel, …), etc.

  • Stacklet | Create Virtual Images On The Fly – This site will be the home of all development of the stacklet engine, a new way of creating bootable images for virtualization software such as Xen.
