Scoring the DNS Root Server System
The process of rolling the DNS Root’s Key Signing Key of the DNS has now started. During this process there will be a period where the root zone servers’ response to a DNS query for the DNSKEY resource record of the root zone will grow from the current value of 864 octets to 1,425 octets. Does this present a problem? Let’s look at the DNS Root Server system and score it on how well it can cope with large responses. It seems that awarding stars is the current Internet way, so let’s see how many stars we’ll give to the Root Server System for their handling of large responses.SC16 live real-time weathermaps

Unable to access Cisco ASA through AnyConnect VPN?
How Does Internet Work - We know what is networking
I stepped on this issue few weeks ago. I was implementing a new ASA Firewall solution, first time for me with software newer than version 8.4.2 It seems that all those stories about changes in the NAT logic after that version were true. This is what I found out about ASA packet processing. Configuration was really straightforward and everything worked fine except one thing. When connected remotely using Cisco AnyConnect I was able to access all devices inside the network (inside ASA firewall), but not the ASA itself. I wasn’t able to connect with SSH nor with ASDM. I, of course,
