Ruby cgi script

I put "script.rb" into the cgi-bin folder of my webhost, but nothing's
happening. What am I doing wrong?

script.rb containing for example:

#!/usr/bin/ruby
puts "<html><body><p>Hello World!</p></body></html>"


(the path to ruby is correct according to the helpfiles from my
provider)

I very much doubt "nothing" is happening. But perhaps you don't see
anything in your browser.

A better way to test from the client machine is to use telnet instead of
a web browser. Type the following:

telnet www.yourhost.com 80
GET /cgi-bin/script.rb HTTP/1.0
Host: www.yourhost.com
<blank line>

and see what response comes back. Paste it here if it doesn't make
sense.

#!/usr/bin/ruby

Often you will need

puts "Content-Type: text/html"
puts
puts "... rest of output ..."

That may or may not be the problem. You'll need to be more specific
about what you see.

You may also need to set the execute bit on script.rb (chmod +x
script.rb - but if you're on a hosted service you may be able to do this
over FTP/SFTP with a 'site chmod' command. Consult your service
provider)

Well, telnet can't get a connection for some reason, but what I mean
by "nothing's happening" is I put

http://www.myhost.com/cgi-bin/script.rb

and get a nothing but white space in return.

The file is set to executable.

I emailed my provider but it may be a while before I get an answer.

That's bad -- you should figure that out; direct access via telnet is a
useful troubleshooting tool.

What do your logs say?

And if this is bypassing any server handling, you need to provide the
appropriate HTTP headers, not just the HTML...

Then investigate. What *exactly* do you see when you try a telnet?

If you post the real hostname here, we can try it for you.

Hey,

turns out my End Of Line characters had the wrong format.

Problem is fixed now.

Thanks everyone!

Are you sure the hosting provider actually allows telnet connections?

You probably shouldn't use telnet anyway -- try SSH instead.

Dude, totally missing the point -- the idea is to use your local telnet
client to test the connection to *port 80* and directly examine the
http server's response.

Nothing to do with logins, passwords, etc.

Alternatively, the Firefox WebDeveloper plugin allows you to view the http
response.
