opening a port on a server

Anon

hi,
i was wondering if anyone knew how to open up a port on a server like www.domain.com:5000 . so, the files that i can upload files as "root" and view them as "root" (so i can execute "root" commands).

Thanks!

You want to open a port on the server?
Can't be done in PHP that I know of.

Anon

how about .sh files or perl file or a PID file?

anyone?

You could use PHP to exec a Perl program or shell script, yes, but the resulting daemon would have the same uid/gid as the webserver - i.e. not root.
So, if you're the system admin, you could get around this by allowing the webserver uid to run setuid/setgid programs, and creating a setuid Perl program or shell script, but this opens up an INCREDIBLY huge hole in your system's security.

hi,

yes i agree, setuid is a big risk, it opens up a lot of possibilities to hackers. i was just speaking to someone, apparently, i would have to open up a socket via perl script.

i would then use a configuration to set the document root etc.. and load that config file into the executable.

e.g. /path/to/executable < /path/to/config.conf

any ideas,?

Explain the logic behind this step-by-step - I'm not sure I understand exactly what you want to do.
If you want to do it in Perl/PHP, I know I can help you - I just need to know what you want to do.

Anon

hi,
ok basically, this is what i want to be able to do.

i want to upload some php files to a directory outside my web root, somewhere like /opt/test

then i need to execute a perl script that will open up a port (e.g. 6909) and make it so that when someone goes to domain.com:6909 it will load files from /opt/test. Also, i dont want to do this through apache, because if i do it through apache , everytime i execute one of the php scripts it will do it as the user "nobody".

I need to execute the scripts as user "root".

Do you still get what i'm trying to do?

Please let me know

thanks,
Khilan

Anon

Yeah, I understand what you are wanting to do. What does the Perl daemon do when a connection is made to 6909? Just send all the files in that dir, or do some type of command interpretation, or what?

Anon

yeah just show the files in that directory, however, im assuming that all the php handlers are going to have to be added to the config file so the php files will work??
