After enough packets have been collected, the program can then compute the key for the wireless network. As the software makes use of brute-force attack however, cracking the encryption can take between a few hours to several days, based on the activity on the network.
Wireshark is very similar to tcpdump, but has a graphical front-end and integrated sorting and filtering options.. Wireshark lets the user put network interface controllers into promiscuous mode (if supported by the network interface controller), so they can see all the traffic visible on that interface including unicast traffic not sent to that network interface controller's MAC address.

On various routers, this TCP or UDP port 9 for the Discard Protocol (or port 7 for the Echo Protocol relaying ICMP datagrams) is also used by default as a proxy to relay Wake-on-LAN (WOL) magic packets from the Internet to hosts on the local network in order to wake them up remotely (these hosts must also have their network adapter configured ...
Packet capture is the process of intercepting and logging traffic. As data streams flow across the network, the analyzer captures each packet and, if needed, decodes the packet's raw data, showing the values of various fields in the packet, and analyzes its content according to the appropriate RFC or other specifications.
Packet crafting is a technique that allows network administrators to probe firewall rule-sets and find entry points into a targeted system or network. This is done by manually generating packets to test network devices and behaviour, instead of using existing network traffic. [ 1 ]
The port scanner generates a SYN packet. If the target port is open, it will respond with a SYN-ACK packet. The scanner host responds with an RST packet, closing the connection before the handshake is completed. [3] If the port is closed but unfiltered, the target will instantly respond with an RST packet.
Since the authentication server has to store the password in clear-text, it is impossible to use different formats for the stored password. If an attacker were to steal the entire database of passwords, all of those passwords would be visible "in the clear" in the database.
