dnmap Package Description

dnmap is a framework to distribute nmap scans among several clients. It reads an already created file with nmap commands and send those commands to each client connected to it.

The framework use a client/server architecture. The server knows what to do and the clients do it. All the logic and statistics are managed in the server. Nmap output is stored on both server and client.

Usually you would want this if you have to scan a large group of hosts and you have several different internet connections (or friends that want to help you).

usage: /usr/bin/dnmap_server <options>
options:
  -f, --nmap-commands        Nmap commands file
  -p, --port        TCP port where we listen for connections.
  -L, --log-file        Log file. Defaults to /var/log/dnmap_server.conf.
  -l, --log-level       Log level. Defaults to info.
  -v, --verbose_level         Verbose level. Give a number between 1 and 5. Defaults to 1. Level 0 means be quiet.
  -t, --client-timeout         How many time should we wait before marking a client Offline. We still remember its values just in case it cames back.
  -s, --sort            Field to sort the statical value. You can choose from: Alias, #Commands, UpTime, RunCmdXMin, AvrCmdXMin, Status
  -P, --pem-file         pem file to use for TLS connection. By default we use the server.pem file provided with the server in the current directory.

dnmap_server uses a '<nmap-commands-file-name>.dnmaptrace' file to know where it must continue reading the nmap commands file. If you want to start over again,
just delete the '<nmap-commands-file-name>.dnmaptrace' file

dnmap_server Usage Example

Create a text file containing the nmap commands that the clients will run. Pass the file dnmap.txt (-f) to start the server:

root@kali:~# echo "nmap -F 192.168.1.0/24 -v -n -oA sub1" >> dnmap.txt
root@kali:~# echo "nmap -F 192.168.0.0/24 -v -n -oA sub0" >> dnmap.txt
root@kali:~# dnmap_server -f dnmap.txt
