I am trying to work thorugh creating some rainbow tables - LM. What I would like to include is a new character set so I added the following to the charset.txt file:
alpha-numeric-symbol14-space = [ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!@#$%^&*()-_+= ]

Yes, I know - Rather large with 77 characters.

The command I issued to begin generation is:
rtgen lm alpha-numeric-symbol14-space 1 7 0 2400 44000000 all

From my understanding, the valuse should create separate files to fit onto a CD, if Icalculate properly, each table will be 671Mb.

How many tables will be created though as I am not sure how to calculate that? In reality this is a two part question as I need to know if it will simply stop generation after the first 671Mb table is done or will it continue on and if on, how many more tables will be added. Then, the one part I am really confuzzled on ....
rtgen lm alpha-numeric-symbol14-space 1 7 0 2400 44000000 all
rtgen lm alpha-numeric-symbol14-space 1 7 1 2400 44000000 all
rtgen lm alpha-numeric-symbol14-space 1 7 2 2400 44000000 all
....

How do you calculate how many commands need to be issued to generate all possibilities?

Doesn't answer your question very well, but...
If you would like to have a table set to break each possible LM-hash
you need 200 tables wich a chain of 9000. Each table is about 625MB.

How did you figure on 200 tables? Also - The table with the command:
rtgen lm alpha-numeric-symbol14-space 1 7 0 2400 44000000 all
is roughly 672 MB per generation.

I am still trying to figure out how I would calculate the tables needed and is there any way to tell what hashed will be in each table? The reason for asking that is because I have created 2 tables already and still no passwords broken - Hashes not found for simple passwords like:
  • testTEST
  • test123
  • (TEST)
  • (test1)
Is the command I issued right or did I set the parameters incorrect?

Thank you
