Server Virtualization

The mail server is slated to be virtualized in 2016. Notes pertaining to the mail server VM configuration should be maintained here.

Apache

Overview

Apache is installed on Mail server as a content/image server for Infonet. Signature capture files from Atlas are sent along with the waybill file via FTP to the mail server, and the Carrier Shipments program on Infonet displays these images files (bmp). Instead of implementing an automated process to transfer and keep the image files on another server, it was decided to make the files available to Infonet (Websmart Apache server) by installing a Apache on mail.

Installation details

The Apache installation was downloaded from ApacheHaus and the entire folder/installation is contained in C:\www. Since there are no web pages or content to be served, but rather just directory browsing "C:\FTP Root\Atlas", the file folder structure is left at its default. Thus all of Apache can be found in "C:\www\Apache24\".

Configuration

Below are critical details regarding this Apache installation, all of which are set in "C:\www\Apache24\httpd.conf".

• Listen only on 172.30.25.3
• Port: 4001
• Implicit deny on root "/" directory
• Specified <Directory "C:\FTP Root\Atlas"> for directory browsing of folder where the images are located.
• Specified Alias /atlasimages "C:/FTP Root/Atlas" so that URLs can refer to /atlasimages instead of actual folder path (security measure).
• Specified Require 172.30.16.0/21 to allow only intranet access to <Directory /FTP Root/Atlas">.

Despite no port-forwarding for TCP 4001 on the UTM, an explicit rule to deny access to that port for the public address of the mail server may be considered.
