netdiscover

Active/passive ARP reconnaissance tool for discovering hosts on a network.

Netdiscover

by Jaime Penalba jpenalbae@gmail.com

Welcome to official Netdiscover repository (since Feb. 05, 2019).

Netdiscover is a network address discovering tool, developed mainly for those wireless networks without dhcp server, it also works on hub/switched networks. Its based on arp packets, it will send arp requests and sniff for replies.

Its my first public C tool, so don't be too hard with me, if some parts on the code looks like obfuscated or are unreadable, and feel free to send suggestions to https://github.com/netdiscover-scanner/netdiscover/issues or patches (PR) to https://github.com/netdiscover-scanner/netdiscover/pulls.

Also notify me for any bug or compilation error, it must compile with gcc 2.95 or newer.

An excessive CPU consumption happens on OpenBSD, due to threads design and the use of pcap_open_live() with pcap_loop(), any suggestions for fix are welcome.

Requirements

  • libpcap
  • libnet > 1.1.2

Build

$ ./update-oui-database.sh (optional, to update the MAC addresses list)
$ ./autogen.sh
$ ./configure
$ make
# make install

To return to original source code, you can use '$ make distclean' command.

Bugs & Contact

Feel free to notify me about any problem, bug, suggestions or fixes at: https://github.com/netdiscover-scanner/netdiscover/issues or https://github.com/netdiscover-scanner/netdiscover/pulls
