Script `iax2-brute`

Script Summary

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
