Hi,

You can use editcap for that, option -E:

   If the -E flag is used to specify a probability (between 0.0 and 1.0 inclusive), Editcap uses that probabil-
   ity to apply errors to each data byte in the file.  For instance, a probability of 0.02 means that each byte
   has a 2% chance of having an error.  This option is meant to be used for fuzz-testing protocol dissectors.

So you take a capturefile, spool it through editcap and let it insert the
amount of errors you want.

Thanx,
Jaap
