telnet gaia.cs.umass.edu 80
GET /kurose_ross/interactive/index.php HTTP/1.1
Host: gaia.cs.umass.edu
(Press the carriage return twice after typing the last line.) This opens a TCP con- nection to port 80 of the host gaia.cs.umass.edu and then sends the HTTP request message. You should see a response message that includes the base HTML file for the interactive homework problems for this textbook. If you’d rather just see the HTTP message lines and not receive the object itself, replace GET with HEAD
