Help with cracking krb5tgs hash

[headlessfish]

Hi all,

When I have tried cracking the krb5tgs hash using -m 13100, I get token length exception. 

What does this exception mean? Is there a possibility that the hashes are bad?

please test with the example hash from https://hashcat.net/wiki/example_hashes and compare your hash with the example hash.
Most of the time it's just a matter of removing the file names from the "hash", depending on how you extracted/generated that hash.
