Unix Tip #4587- October 2, 2014


SEARCH : Home : Help : Today's Tip

Suppose we want to check whether the web server is running or

not, but we don't have any browsers ( lynx, IE, Netscape ...),
then there is a simple way of doing that. Just telnet to that
machine on the http port ( port no 80 in general).

% telnet

And then, say "get /" (without quotes). If the webserver is running,
it displays the HTML script of the homepage or basic info and closes the
connection to the remote host.

% telnet yahoo.com 80
Trying 204.71.200.245...
Connected to yahoo.com.
Escape character is '^]'.
get /
HTTP/1.0 302 RD
Location: http://www.yahoo.com/

Connection closed by foreign host.
