I am testing an Apache server. Normally I open x.x.x.x/directory/index.php in Firefox, then read the httpd/error_logs and troubleshoot.

My question is, what if I don’t have a Web browser (e.g., Chrome/Firefox) on my test system? How can I do an equivalent test via the terminal? I tried ping x.x.x.x/directory/index.php but it doesn’t work that way.

Using ping would never work. All ping does is send/receive ICMP packets from a network address. So in your example, the only thing you could actually “ping” is ping x.x.x.x with the remainder of the URL (/directory/index.php) just choking ping as it attempts to resolve the whole URL as if it were a hostname. The error would be something like:

ping: cannot resolve x.x.x.x/directory/index.php: Unknown host

But for the specific type of web server testing/debugging you are looking for, I usually use curl but specifically I use curl -I -L which will throw back just basic response headers and follow any location redirects the server might have in place; the -I flag tells curl to just show the header and -L flag tells curl to follow any server redirects it encounters.

For example, if I run this curl -I -L command on google.com:

curl -I -L google.com

I get the following response headers:

Note there are two headers returned:

  • HTTP/1.1 301 Moved Permanently
  • HTTP/1.1 200 OK

This is useful not just for Apache server testing but also useful for debugging mod_rewrite rewrite rules and such.

This curl -I -L method is far more useful and efficient than using a visual browser like Chrome or Firefox since those programs are designed to optimize browsing speed by caching content. Which means you can make an adjustment to your Apache server one second, but the visual browser won’t necessarily show the change right away unless you clear the cache or force the page to reload a few times. The curl -I -L shows you exactly what the server at that moment is doing in response to your request which is exactly what you want/need when debugging server configs.


The command you want is either curl or wget (depending on your personal preferences). These commands make a HTTP request to the server. They're not great for simulating the load of an entire page (they don't, by default, load the assets referenced by the HTML page, and they can't execute javascript or interact with the page at all), but it doesn't sound like you're after anything that advanced. So, curl or wget will almost certainly work fine for you.


@womble is right. However, if you don't have curl or wget, you can use telnet:

telnet x.x.x.x 80
GET /directory/index.php HTTP/1.1
Host: x.x.x.x

Then hit Enter one more time (for the end of headers) and you’ll get the raw HTML. You may have to hit Ctrl+D (Unix) or Ctrl+Z (Windows) to exit if the server uses keepalive.


You may want to use a text based browser. This option will let you traverse the web page and test more of its components. Things like forms for example, since it is a full-fledged browser.

Use lynx, or its younger brother links, or elinks.

  • elinks worked the best. lynx wasn't able to display a table properly, the cells were out of the column position and links wasn't able to save the output to file.

You can issue a GET request with OpenSSL:

openssl s_client -quiet -connect cdn.sstatic.net:443 <<eof
GET /stackexchange/js/universal-login.js HTTP/1.1
Connection: close
Host: cdn.sstatic.net


Note that you can also use "HTTP/2", but be careful because some servers (e.g. github.com) do not support it.


If you want to actually view the page, I would recommend using Lynx, which was one of Michael Hampton's recommendations. It renders the HTML and the page can be interacted with via the keyboard. Just don't expect any fancy animations or pictures. :)

It is available via virtually all package managers, the ones on Mac OS X included.
