Tethereal And Capture Files

• If we want to sniff without a GUI (because we're remote, because the GUI is slow for fast traffic...), we can use "Tethereal".
• Running:

  tethereal port 25 and host mail.actcom.co.il

• To Capture into a log file:

  tethereal -w mail-sniff.cap port 25 and host mail.actcom.co.il

• To view the log file using "Ethereal" - "File -> Open".
