-6, -ipv6: enable IPv6 (order of precedence).-4, -ipv4: enable IPv4 (order of precedence).The quickest way to run the script and test your server, is to run it directly with python and provide as positional argument the domain or ip of your server: python ssh-audit.py įor a more detailed CLI usage, you can specify some arguments to the tool with the following options: For more information about ssh-audit, please visit the official repository at Github here. To download the latest release of ssh-audit, you can simply clone the source code of the official repository at Github using git: git clone Īfter cloning, change of directory to the cloned one: cd ssh-auditĪnd proceed with the rest of the tutorial. Once you have analyzed each and every one of these parameters, you will get a complete report indicating from when this option is available, if it has been eliminated or disabled, if it is unsafe, weak or if it is safe. At the level of communications encryption, it is able to verify the key exchange algorithms, the host's public key, symmetric encryption when communication has already been established, and also the information authentication messages. The main features of ssh-audit is that it is able to audit each and every part of the SSH server, it will be able to detect the login banner, it will detect if we are using a totally insecure protocol like ssh1 and even if we are using compression with The zlib library. no dependencies, compatible with Python 2.6+, Python 3.x and PyPy.historical information from OpenSSH, Dropbear SSH and libssh.
