I will second that note. I am 39 years old, have been running windows based servers for around 25 years, I have a certificate 3 and 4 in networking with security components, about half way through my bachelor of comp sci and about to take on my diploma in networking. I have taken steps to completely isolate my servers on the network, including but not limited to multiple gateways, routing, firewalls and port management. Do not do what I am doing as it will open up not only your server but your entire network to attack.


NEO: Please don't be mad with me, I do understand and I do welcome your advice however as mentioned before, I am not concerned with the security issues of privately hosted public minecraft servers.

I would like to propose a more secure way of doing this, which after some testing I have found works just as well. Rather than adding www-data to the sudoers, simply use php to write to a file and have a script monitor that file for changes. The limitation is that a script would likely be run on a cron job which I think the minimum interval is 1 minute. If you would like more help with this method, please create a new thread.



Here is the php code to write to the file.

Code:
<?php

if ($_GET['start']) {
  $old_path = getcwd();
  chdir('/my/path/');
  
  # This code will run if ?run=true is set.  
  $output = shell_exec("echo 'start' > ./operations.txt"); # You can also use >> to append.
  echo $output;

  chdir($old_path);
}
?>


<!-- This link will add ?run=true to your URL, myfilename.php?run=true -->
<a href="?start=true" color="green">start</a>

lsb_release

FSG(1)									FSG								    FSG(1)

NAME

       FSG - manual page for FSG lsb_release v1.4

SYNOPSIS

       lsb_release [OPTION]...

DESCRIPTION

       FSG lsb_release v1.4 prints certain LSB (Linux Standard Base) and Distribution information.

       With no OPTION specified it is the same as -v.

OPTIONS

       -v, --version

	      Display the version of the LSB specification against which the distribution is compliant.

       -i, --id

	      Display the string id of the distributor.

       -d, --description

	      Display the single line text description of the distribution.

       -r, --release

	      Display the release number of the distribution.

       -c, --codename

	      Display the codename according to the distribution release.

       -a, --all

	      Display all of the above information.

       -s, --short

	      Display all of the above information in short output format.

       -h, --help

	      Display this message.

FILES

       If  the	installation  is LSB compliant, the "/etc/lsb-release" file should contain the LSB_VERSION field. The value of the field should be
       the version number of the LSB specification against which the installation is compliant. If the installation is not  compliant,	the  above
       field should not be present.

       Optional  fields  are  DISTRIB_ID, DISTRIB_RELEASE, DISTRIB_CODENAME, DISTRIB_DESCRIPTION and can be used to overwrite information which is
       parsed from the next file.

       The "/etc/[distrib]-release" file contains a description line which is parsed to get information (especially on currently non-LSB compliant
       systems).

       The required line style is:
       "Distributor release x.x (Codename)"

       Where Distributor can be a couple of words, but then concatenated (i.e. Linux Foo BarLinux Linux -> FooBarLinux),
       x.x starts with a digit followed by any non-blank characters, Codename will also be concatenated (blanks cleanup only).

       And release is a keyword not to be used in DISTRIB_DESCRIPTION if you don't want to overwrite "/etc/[distrib]-release" data.

       Notice:	To  support  the Debian distributions' lack of information (see "/etc/debian_version" file) some have been directly added into the
       lsb_release script.

EXAMPLES

       The /etc/lsb-release file contains:

       LSB_VERSION="1.0"
       DISTRIB_DESCRIPTION="I enjoy using my distrib"

       And the /etc/foobar-release file contains:

       My Linux Distrib release 1.0RC4 (TryIt)

       $ ./lsb_release --all
       LSB Version:    1.0
       Distributor ID: MyDistrib
       Description:    I enjoy using my distrib
       Release:        1.0RC4
       Codename:       TryIt

       $ ./lsb_release -a -s
       1.0 MyDistrib "I enjoy using my distrib" 1.0RC4 TryIt

       Then simply without the "/etc/lsb-release" file, that means result on a non-LSB compliant distrib:
       $ ./lsb_release -a
       LSB Version:    n/a
       Distributor ID: MyDistrib
       Description:    My Linux Distrib release 1.0RC4 (TryIt)
       Release:        1.0RC4
       Codename:       TryIt
