Passive Ethernet Tap Throwing Star Tap Network Packet Capture Mod Replica

DESCRIPTION

Bundle1:  Only 1PCS Throwing Star Tap Board

Bundle2: 1PCS Throwing Star Tap Board And 4PCS RJ45 Connector

The Tap Pro is a paive Ethernet tap, requiring no power for operation. There are active methods of tapping Ethernet connections (e.g., a mirror port on a switch), but none can beat paive taps for portability. To the target network, the Tap looks just like a section of cable, but the wires in the cable extend to the monitoring ports in addition to connecting one target port to the other.

The monitoring ports (J3 and J4) are receive-only; they connect to the receive data lines on the monitoring station but do not connect to the station’s transmit lines. This makes it impoible for the monitoring station to accidentally transmit data packets onto the target network.

The Tap is designed to monitor 10BASET and 100BASETX networks. It is not poible for an unpowered tap to perform monitoring of 1000BASET (Gigabit Ethernet) networks, so the Throwing Star Tap intentionally degrades the quality of 1000BASET target networks, forcing them to negotiate a lower speed (typically 100BASETX) that can be paively monitored. This is the purpose of the two capacitors (C1 and C2).

Like all paive Taps, this device degrades signal quality to some extent. Except as described above for Gigabit networks, this rarely causes problon the target network. In situations where very long cables are in use, the signal degradation could reduce network performance. It is a good practice to use cables that are not any longer than neceary.

Usage

Use Ethernet cables to connect the Tap (J1 and J2) in line with a target network to be monitored.

Use Ethernet cables to connect one or both of the monitoring ports (J3 and J4) to ports on one or two monitoring stations. Each port monitors traffic in one direction only.

Use your favorite software (e.g., tcpdump or Wireshark) on the monitoring station(s) to capture network traffic.

ADVANTAGES AND BENEFITS

With its portability and price, the Tap Pro has become a go-to device for network monitoring among information security profeionals. Designed by and for the open-source community, this paive tap is a useful addition to your field kit
