|
|
Performs brute force password auditing against the Asterisk IAX2 protocol.
|
|
Guessing fails when a large number of attempts is made due to the maxcallnumber limit (default 2048).
|
|
In case your getting "ERROR: Too many retries, aborted ..." after a while, this is most likely what's happening.
|
|
In order to avoid this problem try:
|
|
- reducing the size of your dictionary
|
|
- use the brute delay option to introduce a delay between guesses
|
|
- split the guessing up in chunks and wait for a while between them
