nmap-update — Updater for Nmap's architecture-independent files
nmap-update [ options ] [ channel ]
nmap-update is an updater for Nmap's architecture-independent files. It is used to keep up to date with changes and new scripts for the Nmap Scripting Engine.
Updates are distributed in the form of “channels”, which are named directories that usually correspond to Nmap version numbers. When nmap-update is installed, it will pull from the channel corresponding to the version of Nmap it was installed with, until Nmap and nmap-update are upgraded as a whole.
The program works by updating from a remote Subversion repository. To supply authentication credentials, create a configuration file:
The contents of the file should be:
username = username password = password
Alternatively, you can cache your credentials more securely if you have the
svn command-line program installed. Run the command
svn ls https://svn.nmap.org/updates, enter your credentials, and agree to cache them when asked.
- Install to
directory. Normally installation goes to a suitable place under your home directory:
.nmap/updates/channelon Unix and
AppData\Roaming\nmap\updates\channelon Windows. This option can be used by root to install updates system-wide.
- -h, --help
- Show a help message and exit.
- -r, --repo
- Use the given repository and path rather than the default. For example,
- Authenticate with the given username.
- Authenticate with the given password.
- -v, --verbose
- Be more verbose. Show the used channel and repository.
Any other arguments are taken to be the names of channels to load from. The channels are tried in order until one is successful.
