Linux tips
I am and will be very short of time for a couple of weeks, so most probably these will be the last posts for the month. If you’ve read and followed my advice on re-creating the swap partition after failed hibernation, there is one caveat I discovered: after recreating, the swap partition is not automatically…

Don’t claim that you have a revolutionary technology…
Unless you have done your research. I was listening to the latest CyberSpeak podcast yesterday (a very nice podcast by the way) and I heard the guy (Chad McMillan) who was being interviewed talking about a revolutionary new technology for identifying packed executables by signature which he will be presenting at BlackHat. I wonder how…

Perl, Windows and File Locking
For some Perl scripts you want to make sure that only one instance of it is running at the same time. So you use lockfiles, in a way like this: open(LockFile, “>$lock_file”) or die(“Failed to lock file $lock_file, error: $^E”); flock(LockFile, LOCK_EX) or die(“Failed to lock file $lock_file”); The idea being that the OS guarantees…

Hack the Gibson #73 & #74
Well, don’t hack it. Actually the last two episodes of Security Now! were very insightful and as far as I know without major mistakes. The interview with Peter Gutmann is very interesting and if you have time you should read the original paper: A Cost Analysis of Windows Vista Content Protection. My opinion about it?…

Hacker challenge over
The Christmas (Hacking) Story challenge is over and unfortunately I didn’t win :), so I publish my response: What is interesting about the files that Ralphie could see on the lamp server? nc is most probably netcat (http://netcat.sourceforge.net/), the “network swiss army knife” (the fact that it’s executable, as can be seen from the directory…

Implementing Web Services with Open Source Software
