In this post I tested in my lab if tunneling with icmp really opens a hole that a simple stateful firewall cannot realize. ICMP is a protocol that is opened everywhere since we need it for our daily job and honestly I have never thought that even with this I open a hole on firewall. […]

The clusterXL_admin command is really fine, but i think it is not ready now. It has just one big problem – in my point of view. But the whole post has really low priority…it is really only for geeks. :-) Lets say the cluster members should be restarted but with a controlled way. How can […]

This post is a reference for me in case in the future I have to change again the settings of my wireless HP printer. I had to change today my wireless settings as I have a new wireless router and wanted to use new SSID. The old router is a repeater-bridge now with the old […]

I have tested some tools usable for CMA migration and honestly I do not have more luck as earlier. The Software Version I used is R70.40 but the tools are from R75. For migrate export command I mounted the R75 ISO image under R70.40. The IP of the CMA is 2.2.2.2 1. Export CMA -change […]
