That eliminated sites like Wikipedia and Google. It had to be a site that is substantially about I.T.

That eliminated sites like Experts-Exchange. It's okay if they charge for premium services, but there just had to be a lot of good stuff for fee.

It had to be a site that offers good stuff for free.

It had to be a site that provides information I need.

This would have been a fairly easy list to compile, but then I decided to filter sites by six criteria as follows: This month, I'm sharing my top ten favorite websites for I.T. Last month, I shared my top ten favorite tools for I.T. ASDM demo mode provides a great way to explore the ASDM and familiarize yourself with its extensive capabilities.

Once the demo software is installed, you can run it by starting the ASDM launcher and checking the box to 'Run in demo mode'. For example, I recently downloaded and installed asdm-demo-621.msi.

Make sure to download the appropriate demo version for the version of ASDM software you're running. You must first download the ASDM demo software from Cisco using your Cisco login. Here's another handy learning tool for the Cisco ASA: You can run the ASDM in demo mode. On the General tab, in the Communications section, check the box to 'Preview commands before sending them to the device'.

Here's how to do it: In the ASDM, click on Tools>Preferences. It's easy and it's also a great way to familiarize yourself with the command-line interface (CLI). One of the things I always teach in our Cisco ASA workshops is how to preview commands in the Adaptive Security Device Manager (ASDM) before sending them to the appliance. Falco Timme as an excellent tutorial (all of his tutorials are excellent) at.

If you want to go crazy with graphics, install beryl as well. Presumably, it's similar on Debian systems, but you would use apt-get instead of yum. # yum groupinstall 'KDE (K Desktop Environment)'.# yum groupinstall 'GNOME Desktop Environment' or.Here's how to do it (two steps) on Red Hat-based systems (Red Hat, Fedora, CentOS): If you don't, you'll get errors such as 'no server 'X' in PATH' or 'xinit: Server error' If you don't have X, you don't have graphics, so you have to install X before you can use the desktop environment. The thing to remember is that X provides the foundation for graphics in Linux/Unix. Many of the issues seem to be related to installing the desktop environment without installing the X server. I've seen a lot of forum posts with questions about installing desktop managers such as Gnome and KDE after you perform the initial installation of Linux. There is a fair amount of complexity involved in getting it right, but I'll blog on it and let you know what I find. A more permanent solution (perhaps it would be better described as a 'less temporary' solution, since there probably is no permanent solution other than disconnecting from the Internet) will be to create a set of firewall rules to identify an attack (say, an accelerated number of connection requests within a set time frame) and drop the packets from that source. This is not a permanent solution and it won't work for a Distributed DOS attack, but it did allow my server to begin answering HTTP requests again. I'm not including explanations of all the options here. Here's the command: ' ip route add blackhole w.x.y.z/32' (where w.x.y.z is the address I wanted to block and /32 is the mask) I then created static blackhole routes for those three IP addresses to block the source of the attack and my server was back up.I found a large number of connections from three unique IP addresses. I then used ' netstat -atun awk '' cut -d: -f1 sed -e '/^$/d' sort uniq -c sort -n' to identify which IP addresses had the most connections open.I first used ' netstat -lan grep -c :80' to check the number of connections to port 80.

It wasn't too bad and I was able to use several commands to figure out what was happening and deal with it. Sometimes I feel like I'm living in a Rube Goldberg contraption! One of our servers got hit with a DOS attack last Friday night.
