This is worth reading.

Update: The Debian people created a website with instructions to rollover keys. And there’s also a Perl script for testing SSH servers an other packages for vulnerabilities.
Update 2: Bruce Schneier jumped in. And here is a xkcd cartoon and some source.
Update 3: Here are some useful tips (in German).

After some problems to get an Asterisk server talking to an Inode Telenode gateway (incoming calls did not work) I tried the following configuration for sip.conf and it worked like a charm:

srvlookup=yes
nat=yes
allow=all
externip=81.223.xxx.yyy
localnet=10.0.0.0/255.255.255.0
register=0999999999:password@px.voip.inode.at
incominglimit=10
and users.conf:
context=DID_trunk_1
dialformat=${EXTEN:1}
canreinvite=yes
hasexten=no
hasiax=no
hassip=yes
host=px.voip.inode.at
port=5060
type=peer
registeriax=no
registersip=yes
secret=password
trunkname=Custom – Telenode
trunkstyle=customvoip
username=0999999999
callerid=0999999999
fromdomain=px.voip.inode.at
contact=0999999999
fromuser=0999999999

When you try to install the latest firefox release on openSUSE 10.2 (before openSUSE offers one), firefox will throw an error like “Installlocation has no properties” in the javascript console.

After I killed my SuSE 10.1 installation on my good old IBM Thinkpad yesterday (I tried to upgrade to the latest Gnome release without success), I installed openSUSE 10.2 today.
The installation worked like a charme and the system installed without any problems.
Before installing the new system I did a backup of my data partition (I [...]

Fastjack und Joern und Andreas haben vollkommen Recht! Die CapsLock-Taste macht absolut keinen Sinn und ist überflüssig. Davon abgesehen, tendiere ich generell dazu, diese Taste auf meinem Thinkpad immer unabsichtlich zu berühren, und das verursacht nervige und zusätzliche Tipparbeit.
Unter Linux lässt sich die Taste ganz einfach mit xmodmap -e “remove Lock = Caps_Lock” bzw. xmodmap [...]

Aptana ist keine Babynahrung, sondern eine – trotz Beta (na klar!) – sehr ausgereifte IDE für Javascript, HTML, XML und CSS.  Nachdem ich das heute bei Markus gesehen hatte, musste ich es sogleich testen.
Unter Windows XP verlief die Installation recht unproblematisch, das Tool selbst ist angenehm stabil. Unter SuSE 10.1 war es dann nicht ganz [...]

Sometimes I need IE for testing web applications and today I found IEs 4 Linux, a great resource if you want to run IE (5, 5.5 and 6) on linux.
And besides that, it is really easy, download IEs4Linux, start ./ies4linux and after a few minutes of downloading you are there!
