• Content Rewriting through Cisco WebVPN

    By default, all Cisco security appliances process all WebVPN traffic through a content rewriting engine that includes advanced elements such as JavaScript and Java to proxy HTTP traffic. That is a good security feature but if you are running a web application which you want to be accessible through WebVPN this content rewriting (also called ‘mangling’) may cause you a lot of functionality issues.

     

    Here are some suggestions:

    You can disable content rewriting for selected web resources using ‘rewrite’ command:
    Example: ‘rewrite order 100 disable resource-mask *.js’

     

    But I believe that this will not fix your issues and ...

  • HP One Button Disaster Recovery

    Looking back on the past week, I had some very extreme moments with one of our tape libraries. The device came as fully compliant with ProLiant servers and we expected it to behave exactly as such. However, this was not exactly the case.

    I have lost three days configuring a test backup server. I pushed the test scenario so far as to install it as additional domain controller, secondary DNS, RADIUS, replicating policies and applying rules, data movement, configuring RAID arrays and agents. When I had finally finished the setup, I made a full backup and system state backup with ...
  • Teredo Tunnels

    How many of us are aware of this technology? Do we know what this is?
    If the answer is ‘YES’ you are probably already blocking rogue tunnels like this in your network, if the answer is ‘NO’ you need to take some actions as soon as possible.

    What is a Teredo tunnel? The name itself means a shipworm drilling in boat hulls, but in technological terms it is something worse. This is IPv6 transition technology that uses IPv6 over IPv4 networks to punch holes in NAT devices.

    How does it work? If anyone of your internal corporate users wants to ...
  • Trip to Anaheim, CA

    We at Telerik love Cisco. We love Cisco so much – we keep the boxes from our devices in an air-conditioned room :) Well, jokes aside – Cisco equipment and its optimal integration and use in a hi-tech environment puts a lot of strain on the administrators unit. We need to stay on point and sharp for newer technologies, newer threats, and ever growing demand. To sharpen my skills I was invited to attend the Cisco Networkers Event at Anaheim, CA.

    I will spare the long flight details, the jet lag, and the gross food on the planes (or the ...
