Two new tutorials on Internet Engineering are available now from
Mi Islita.com Minerazzi.com: MTU and MSS Tutorial [pdf]
Note: These tutorials were moved to Minerazzi.com. See
Both tutorials are based on lecture material provided in class during the IE Part 1 course. These can be used as reference material for other courses such as Network Security, Internet Engineering, Internet Architecture, etc.
The first one is an introduction to packet fragmentation analysis while the second one delves into experimental techniques on maximum transmission unit and maximum segment size calculations.
The tutorials can be used to understand Ping of Death, Fragmentation Offset Attacks, Tiny Fragmentation Attacks, Firewall Fragmentation Attacks and other forms of hacks.
