Upgrading to latest Scientific Linux release
Scientific Linux was released a while ago. I'm still running 6.1. Time to update...
yum -y --releasever=6.2 update
Done.
$ cat /etc/system-release Scientific Linux release 6.2 (Carbon)

Tiny Core Linux 4.5
Es ist schon eine Weile her seit ich das letzte Mal mit Tiny Core Linux gespielt habe. Nach der Installation startet Tiny Core Linux extrem schnell. Als Vergleich ein Start von Alpine Linux und einer von Tiny Core Linux in einer virtuellen Maschine.
Alpine Linux: 12 s (bis Login)
Tiny Core Linux: 6 s
Die Messung ist nicht ganz fair, denn eine Alpine Linux-Instalaltion ist etwas umfangreicher als die von Tiny Core Linux. Der Start von Fedora dauert aber in jedem Fall um einiges länger. Ausser ich verzichte auf den Start der grafischen Oberfläche...der Vollständigkeithalber muss ich mal die Zeit messen bis eine Minimalinstallation von Fedora bereit ist. Dem Gefühl nach wird so sich etwa in der Grössenordnung von Alpine Linux bewegen
Sehr schön ist, dass bei Start von Tiny Core Linux eine Auswahl mit Window-Manager zur Verfügung steht.

Wieder einmal hat jemand eine Umfrage gemacht...repräsentativ? Wohl kaum. Erstaunliches Ergebnis? Nein. Langweilig? Ja, sehr.
Arch Linux 14.56% (1,669 votes)
Ubuntu (and variants) 51.15% (5,863 votes)
Linux Mint 15.78% (1,809 votes)
Fedora 8.44% (967 votes)
Debian 10.08% (1,155 votes)
Total Votes: 11,463
Fazit: Trau keiner Statistik aus einer Umfrage, welche du nicht selber "optimiert" hast, resp. stell einer Gruppe die richtige Frage und daraus resultiert das richtige Resultat.
crunch and Fedora
crunch is a wordlist generator. For test cases and demonstarations it's very useful to have a simple wordlist prepared to show how it works. I think that generating worklists is a missing feature for the Fedora Security Lab.
While compiling crunch on Fedora 16 x86_64 I ran into an issue.
/usr/include/gnu/stubs.h:7:27: fatal error: gnu/stubs-32.h: No such file or directory
Installing the corresponding package for 32 bit solves it.
sudo yum install -y glibc-devel.i686
Be aware, the Makefile of crunch will install the binary at a non-standard location.
Let's generate some numbers
./crunch 9 9 0123456789
Keep Metasploit up-to-date
If you have installed Metasploit on Fedora following this article, you can update Metasploit with the following command.
svn update /opt/metasploit4/msf/
or just use
msfupdate
Wireless-Forum hat Geburtstag
Vor neun Jahren hat das wireless-forum.ch das Licht der Welt erblickt. Am 12.04.2003 wurde das Forum für die Öffentlichkeit geöffnet. Mit dieses Postings hat der Admin auf den Umstand versucht aufmerksam zu machen.
Die Anzahl der täglich registrierten Benutzer hat in der letzten Zeit abgenommen und wird wahrscheinlich auch in Zukunft weiterabnehmen.
rtsp-url-brute
In the source of the rtsp-url-brute script the path to the source file (rtsp-urls.txt) is mentioned. But is file is missing. While running nmap against my levelone FCS-0030 camera no URL is found.

I was trying to resolve this with a simple file which contains the last parts of a possible address.

Doesn't work either.
