Packet sniffing: the golden tools

Packet sniffing (aka packet analyzing) can prove a very useful method in providing administrators detailed information on the communication among various servers in a hosted environment. The following tools are indispensable when it comes to packet sniffing:

  1. Microsoft Network Monitor available at http://www.microsoft.com/en-us/download/details.aspx?id=4865 . Wireshark is also a great alternative. However Microsoft Network Monitor is usually preferred in some production environments due to its considerably smaller footprint.
  2. Microsoft Message Analyzer available at https://www.microsoft.com/en-us/download/details.aspx?id=44226.
  3. Microsoft PortQry UI version, available at http://www.microsoft.com/en-us/download/details.aspx?id=24009
  4. Netstat CLI command. Check netstat /? for details.
  5. Telnet for pinging listening TCP/UDP ports.
