I have to send a restart command to an IP camera from a PHP script. The
command is as follow:

http://192.168.1.5/axis-cgi/admin/restart.cgi

where 192.168.1.5 is the address of the camera.

In PHP, my idea was to open a socket connection and send the command, with
the following code:

$host="192.168.1.5" ;
$target="/axis-cgi/admin/restart.cgi" ;
$port=80 ;
$timeout=60;
$br="\r\n" ;
$usarname="root";
$password="password_root";
$sk=fsockopen($host,$port,$errnum,$errstr,$timeout) ;
if(!is_resource($sk)){
exit("Connection failed: ".$errnum." ".$errstr) ;
}
else{
$headers = "GET ".$target." HTTP/1.1".$br ;
$headers.="Accept: */*".$br ;
$headers.="Accept-Language: it".$br ;
$headers.="Host: ".$host.$br ;
$headers.="Authorization: Basic root:password_root".$br.$br;
fputs($sk,$headers) ;

When printing $sk I see the error message

401 Unauthorized
You client does not have permission to get URL /axis-cgi/admin/restart.cgi
from this server

Seems there is something wrong with authentication.

Any idea ?
Is there somebody who uses PHP with Axis camera ? How do you send API
commands to the camera ?


Thank you for your help.

Dont know if this is the right header.
I use allways PHPs CURL extension. It works fine.

e.g.: curl_setopt($curl, CURLOPT_HTTPAUTH, 'username:password');
http://php.net/curl

It requires also an min. PHP version 5.*
PHP 4.4.2+ supports it to but official documentation says "avialable for
version 5 and above". May it helps you.

So long, Ulf

Ulf,
thank you a lot for your answer. I've never used Curl before and I am trying
to do right now what you suggested.

So, after curl_init(), using the function :

curl_setopt($curl, CURLOPT_HTTPAUTH, 'username:password');

I get the same error message as before: 401 Unauthorized.

But looking at curl_setopt() specifications, the option CURLOPT_HTTPAUTH can
be set to values CURLAUTH_BASIC, CURLAUTH_DIGEST and so on depending by the
authentication methods to use.
So I should write for example:

curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_ANY);

Seems that username:password is not accepted as CURLOPT_HTTPAUTH set value.
In that case where should I specify login and password ?

Thank you again.

Stefano

Right. It was my failure. Better to read my posting before send.
Yesterday i used it like my example but with PROXY* Paramater. worry? Smile

The fast and bad way is URL-injection like this:
http://username:password@example.com/...

The other and better way is to change youre code at line:
$headers.="Authorization: Basic root:password_root".$br.$br;

to:
$headers .= 'Authorization: Basic '
. base64_encode('root:password_root') . $br . $br);

The RFC says username:password must be Base64 encoded.

By the way: A good PHP-Library for doing something more with
http/ftp/... (by a easy way) is Snoopy.
http://sourceforge.net hosts it.

YYYEEEESSSSS !!!!
It works now !

To be honest, I tryed the function base64_encode() before but colon was
outside base64_encode.

Thank you very much Ulf. I was working around that problem since last week.

Regards.
Stefano
