Recommend OpenSource or Freeware tool to inspect network traffic between two servers


I am currently in the process of locking down the network communication protocols that are available for use on given Windows application platform.

Can you suggest a freely available tool that will allow me to monitor/identify the commuications protocols that are in use i.e.

  • TCP/IP
  • http
  • https
  • FTP
  • SFTP
