I am going to be using a simple ip limiting system on a site I'm working
on and using php you can get the remote ip simply by calling something
like
<?php echo $REMOTE_ADDR; ?>
Is there a similar method in ruby? I am not using rails, not supported
on the server I'm using. Thanks

That depends on the Ruby web server you are using. The source IP is obtaine=
d=20
from the connection Ruby socket (if Ruby handles the conecction) but if you=
=20
are using a web server that is the responsible of handling the TCP connecti=
on=20
and providing the origin address:port in form of variable and so.

Apache/1.3.34 Ben-SSL/1.55 is the server info. It goes index.php has a
form that is submitted using GET to /ruby.rb. ruby.rb generates the
content for the page depending on the form input. I'm not sure if I'm
all that clear. It's not a ruby web server. It's just a script on a web
server.

So, does PHP call to a Ruby script?

If that, the only way is that PHP passes the source address as a parameter =
to=20
the Ruby script. Note that in your case Ruby is not handling the socket at=
=20
ALL, so it's no way to get the address IP:port except passing it as=20
parameter.

Ah. Ok. Thanks.

The remote ip is a CGI parameters. All webservers should set this, you can=
=20
read it with (assuming you use CGI):

require 'cgi'
$stderr.puts "Remote Addr: #{CGI.new.remote_addr}"

Thanks. I simply did the following:
<?php
echo "<input type=\"hidden\" name = \"ip\" value=\"".$REMOTE_ADDR."\" />
<br />";
?>
and then a
ip = cgi['ip'] in the ruby script.

This is dangerous to rely on. From a security point of a view (why do you
want their IP anyway? question #1.), anyone could just submit a different
`ip' value and you'd record that.

See take Martin's advice as is: CGI.new.remote_addr will return the address
without it being submitted via the PHP script, hence this line of `attack'
is eliminated.

Cheers,
Arlen.

Very good point and I'll consider it. I'm simply using it to get a
general idea of how many times people access it.
