http-header with authorisation
hi,
i'm building a script which should automatically get content from a passwordprotected server. Usually i collect my info by typing
http://user:password@hostname.com
Now i want to do this automatically (and send it to my gsm :-) ). I can get info from a website using a telnet connection to port 80 and then do
get pagename.html
It will return plain html. But that;s for non-protected pages. With protected servers, i get a 401 (authorization required) error. I looked up the RFC but i can;t figure out how it is working ..
Can anybody explain me which header i should send to get the information with my username and password?

$login="user:password";

$res =~ tr|` -_|AA-Za-z0-9+/|;
$padding = (3 - length($login) % 3) % 3;
substr($res,-$padding) = '=' x $padding if $padding;
print "Authorization: Basic $res\r\n";
or
use LWP::UserAgent;
$ua = new LWP::UserAgent;
$ua->credentials($netloc, $realm, $uname, $pass)
or
lwp-request -C user:password http://hostname.com

lwp-request http://user:password@hostname.com

ok, that piece of perl did it's job: i'm now able to create that authorization string.
what i did was
> telnet hostname.com 80
and then IN telnet
Authorization: Basic wt436439085FU {enter}
get index.html
And it doesn't respond.. when i don't paste the authorizationstring i do this
> telnet hostname.com 80
get index.html
and it wil respond with plain html (the 401-script)
So, how do i emulate the correct authorizationstuff with telnet?
BTW, i've increased the points!

ok, we're almost there :-)
i tried to do the following
> telnet hostname.com 80
get index.html HTTP/1.0 {enter}
and then it starts to give me HTML inmediately ... i also tried
> telnet hostname.com 80
get /chatboxes/nightshift HTTP/1.0 Authorization: Basic ZFUocCoBZVcMXVL`=
But that results in a 401 too .. what am i doing wrong?
can i give the 'get'-statement in the command line, something like
> telnet hostname.com 80 get index.html?
greets, jesse

Hello Jesse,
The way you started is ok, but you should give the server a little more info. This should do the trick:
telnet hostname 80
#send the following lines
GET /chatboxes/nightshift HTTP/1.0
Host: hostname #change this!#
Accept: text/html, text/plain
Accept-Encoding: gzip, compress
Accept-Language: en
User-Agent: younameit
Authorization: Basic asdfasdasdf==
#end, the output is comming your way now
Just fill in you encrypted password and it should work
Tha fox! :)

connection closed by foreign host.

Oops sorry, my mistake :0
there should be 2 {enters} behind the Authorization: like {\n\n}
plz try again.

to oxo,
sorry, the thing i posted is very close to your answer: i will withdraw this answer.
ps: the correct is answer is:
telnet hostname 80
#send the following lines
GET /chatboxes/nightshift HTTP/1.0
Authorization: Basic asdfasdasdf==
{enter}
{enter} <- important!

ozo > too bad your authorization-maker did not work, in the end i used the following (thanx to MR_WHO)
lynx -auth={name}:{password} http://hostname.com/ -source
this line retrieves one page, put's the html-code to stdev an then exits. That was exactly what i needed.
I guess that if ozo's authorization-maker would work, i could do it in telnet which requires less systempower, but the lynx-trick worked fine for the current program
