I've installed a LAMP server locally and I want it to only be accessible from my own computer (not even my local network), only through loopback. Is this possible to do securely? If so, how?

The Listen directive in your config should be equal to Listen 127.0.0.1:80

I looked at my /etc/apache2/httpd.conf (assuming this is the config file you mean) and I don't see any previous Listen commands. Am I in the wrong file? Pardon me for the noobness, first server setup. – MaxMackie May 22 '11 at 1:10
the apache config can be split into several files, depending on what distribution you are using. go to /etc/apache2 and do a grep Listen * -r. That will list the files with the Listen directive – freethinker May 22 '11 at 1:14
Conveniently located in Listen.conf! I've changed it and restarted the service. Is there a way to test this from my local machine? Without having to pick up another computer and trying? – MaxMackie May 22 '11 at 1:26

you can do a netstat -nat | grep 80 and check whether port 80 is open on 127.0.0.1 or 0.0.0.0 or your ip address:80. For your case, it should be open only on 127.0.0.1 – freethinker May 22 '11 at 1:32
thanks a bunch @freethinker – MaxMackie May 22 '11 at 1:32

Tell the server to only listen on 127.0.0.1 and ::1.
