Introduction

The abbreviation "OMDR" stands for "obsolete mail domain reporter" and is a small shell script intended to find obsolete MX records to keep your mailserver clean and sane

As a source of currently configured domain can be either
* a textfile, every hosted domain on a seperate line
* a directory tree with the domains

Usage

1. Copy the shell script to your mail server

2. Open the script within an text editor. There are several configuration options at the beginning of the script to adapt the script to your environment. See comment within the script itself!

3. After running the script, you end up with a file that contains all domains that are claimed not to be active any more on that particular mail host

First, set the common name (CN, ~FQDN) for the certificate:

CN=host.domain.tld

Change to the directory where you would like to store the data relevant for certificates, e.g.:

cd /etc/ssl

Then create a private key:

openssl genrsa -out private/${CN}.key 2048

Generate the signing Request, either:
a) interactively, you'll have to answer some questions...:

openssl req -new -key private/${CN}.key -out ${CN}.csr

b) using a customized openssl config file:

openssl req -new -config ${CN}-openssl.cnf -key private/${CN}.key -out ${CN}.csr

Now you may either:
a) send the certificate request to an (official or internal) Certificate Authority to sign the Certificate

b) for testing purposes only, you can also self-sign the certificate:

openssl x509 -req -days 1825 -in ${CN}.csr -signkey private/${CN}.key -out certs/${CN}.crt

When you have received signed (or self-signed) certificate, you can copy all the files to the appropriate location.

Probably you have to create a combined pkcs#12 (.p12, .pfx) file, containing private key and certificates:

openssl pkcs12 -export -in ${CN}.crt -certfile cafile.pem -inkey ${CN}.key -out ${CN}.pfx

(where cafile.pem is the ca certificate bundle of issuing certificate authority)

Clear the shell variable for the Common Name:

CN=

You can actually map network drives to webdav locations. To do so use this:

1. Open Windows Explorer
2. Rightclick on 'Computer'
3. Go to 'map network drive'
4. Choose station/drive letter
5. Enter this path:

\\storage.ownspace.ch@SSL\files\shares\my-files

6. Press OK and your set.

Here you will find some stuff about Windows and Linux including how-to's and some tools. And last but not least, some information about the author, Mike Rhyner.

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
