This blog was originally started to better help me understand the technologies in the CCIE R&S blueprint; after completing the R&S track I have decided to transition the blog into a technology blog.

CCIE #29033

This blog will continue to include questions, troubleshooting scenarios, and references to existing and new technologies but will grow to include a variety of different platforms and technologies. Currently I have created over 185 questions/answers in regards to the CCIE R&S track!! Note: answers are in the comment field or within "Read More" section.

LAND attacks are crafted packets with a source and destination address of the device the attacker is trying to attack.

EX: Interface serial 0/1 with an IP address of 10.0.0.1

"access-list 101 deny ip host 10.0.0.1 host 10.0.0.1"
"access-list 101 permit ip any any"
"inter serial 0/1"
"ip access-group 101 in"
