Prerequisites

The "dig" tool must be installed on your system, and be allowed to be executed from php. If it doesn't work, e.g. if using safe_mode and/or open_basedir restrictions, add the path where dig is located to the two php options:

open_basedir /usr/bin/dig
safe_mode_exec_dir /usr/bin/

Within a VirtualHost, set with php_admin_value <option>.

In addition, TCP port 43 and UDP port 53 need to be open outbound.

Installation

Extract the content of the archive within your web root of the webserver, e.g.

cd <webroot>
tar xvzf dnstools.tar.gz

Usage

Navigate your web-browser to http://<your_host_name>/dnstools/ and enter either the appropriate form.

Description

This tiny script shows you a overview of the virtual machines on QEMU/KVM carrier servers using libvirt as management interface.

It can either show all virtual machines or only the running VMs.

Prerequisites

This PHP Script requires PHP extension libvirt-php

Download

Download the gzip'ped tar archive

Installation

Unpack the archive to a webserver document root with direct access to your libvirt hypervisors over TCP Port 16509 or SSH

Adapt at least the variables $dnsdomain and $arr_hosts to your infrastructure and change $comtype to "qemu+ssh" when SSH instead of direct port access is wanted

Prerequisites:

On a web- or intranet accessible host (access protection highly recommended!):
- Web Server with PHP script language support (shell_exec function has to be enabled)
- Key-based SSH access to mail servers for webserver user

On mail servers:
- Postfix
- sudo

Installation

Unpack the archive beneath a webserver document root

Adapt the variables $mailservers and $user to your needs, if you like to use the selection by sender e-mail address feature, configure also variable $wrapper_cmd

Add the following lines to /etc/sudoers on the mail server(s), assuming user admin for login to the mail server(s) (change it to your needs):

admin    ALL=(ALL) NOPASSWD: /usr/sbin/postsuper
admin    ALL=(ALL) NOPASSWD: /usr/sbin/postqueue
admin    ALL=(ALL) NOPASSWD: /usr/local/bin/mailqueue.sh

(last line only needed for selection by sender address)

If you want to use the selection by e-mail address feature, put mailqueue.sh to some path on the mail server(s) and make it executable, e.g.:

cp mailqueue.sh /usr/local/bin/mailqueue.sh
chmod 755 /usr/local/bin/mailqueue.sh

Try it out using http://yourwebserver/mailqmgr/index.php
