Hello everyone, =]

I need your help,

I'm creating a script that will work in many servers, and there's this part,
where you can update a list, so the script goes from the client's machine to
the central server, opens the file, and in adda line by line in the client
server, it's all working fine, but there's a problem, this list, can't be
available to others, because if I do this:

www.test.com/list/test.txt

I can see the hole list, if I remove the permissions, my script wont work
anymore, what can I do ?

I've thought that I could chmod the file to 0777, make it a copy, and remove
the permission, so the file would't be available for others that just enter
the URL.
But it doesn't work at all, here's the error I get:

Warning: chmod(): Unable to access www.test.com/proxy/ in
/home/test/public_html/clicksentinel/form_classes.php on line 859

Warning: chmod(): No such file or directory in
/home/test/public_html/clicksentinel/form_classes.php on line 859
Sorry, try again later, error at data number5You have an error in your SQL
syntax. Check the manual that corresponds to your MySQL server version for
the right syntax to use near 't have permission to access
/proxy/proxylist.txt')' at line 1

Please, I really need some help,

tks a lot

in face,your mutil server is the same to the hackers' browser,
they communicate via HTTP

what you should focus with is not chmod,
but how to tell the connection from client is from your other server,
or other users' browser.

i think this solution will work:
1.use a script to read the list
1.1.you put your text.txt in a safe path,which can not be accessed by
the internet.
1.2.create a php file to read text.txt to browser
1.3.you navigate to the php script to see if you can get what's in
text.txt

2.add a permission check
2.1 modify the php script , generate a password for it
it maybe like this:
if($serverID=="ocwjkfajd8jkslkcja9eu98uf"){
// disp text.txt conteset
}
else{
// tell error
}
2.2 modify your other server's script,when access the old text.txt,
visit the php script with password instead.
for
example,www.test.com/list/test.php?serverID...jkslkcja9eu98uf
2.3 others doesnot know the password will not receive the content of
text.txt
2.4 you may extend the script,for example,create a single password
for each server

hope help

you may put the list.txt in someplace not accessible to you webserver
(if you own the server), like /var/list.txt

or you can block access with .htaccess (in apache, is the name right?
..htaccess?)

the problem is that the file is going to be accesse from another server, in
fact, a lot of servers.
That's why it's not possible to do that..

ANy other suggestions ?

If the servers are connected to the same LAN, then you can use remote
mounting: http://opensource.weblogsinc.com/en...34000507065907/

If all the servers are running SSH daemons, use the php SSH tools:
http://us2.php.net/ref.ssh2

Alternatively, you can use shell_exec in php to run something like: "scp
server.domain.top:/path/to/file ." from each machine to obtain the file and:
"scp ./file server.domain.top:/path/to/" to upload.

If you can use apache basic authentication, then you can htpasswd the
script:
