CentOS Linux Server Guide

E-Mail Security Virtual Appliance (ESVA)

Part 1: ESVA Installation

Prerequisite

Download the image from http://sourceforge.net/projects/esva-project/files/
Since EVSA is packed under virtual image. You need VMware ESX/Server/ESXi/Player to launch the image. How to setup VMWare and import ESVA image is not discuss here.
ESVA already installed with CentOS Linux. However, you might install/Upgrade the VMtools.

Procedure

Step 1. Login into ESVA console

ESVA login screen

The default setting for the ESVA system is

username : root

password : password

You can either change the root password now or later. If you want to change the password immediately, please run the following command. Remember to use complex password :)

passwd

Step 2. Run the ESVA Setup script

Setup of EVSA is very easy. Run the pre-compiled script

esva-configure

Step 7. UTC Time selection

We do not want a UTC Time selection just press <Enter> button to continue

Step 8. ESVA Host and Network Setup

Next, let us configure our ip address, subnet mask and hostname.

ESVA Host and Network Setup

Note:

"My HostName[localhost.localdomain]" setting is the name of your ESVA. Remember to use a fully qualified name. e.g. mailgate. yourdomain.com. This should be the same as the Internet DNS A record.

ESVA organization information setup

Note:

"Your mailserver's name" setting is the ESVA forwards scanned (clean) mail to. This can be either a name or an IP address. My mail server is mail.1a-centosserver.com

Step 9. MailScanner child process setup

Unless you have a very huge incoming email voulme (more than 2000 messages/hour). The default of 2 should be enough. According to manual, increasing this beyond 3 will require additional memory to be assigned to your ESVA: 5 child process requires 600MB, 1 processor core ; 6-10 child process required 1024MB memory, 2 processor cores.

Step 10. Configure IANA

The two letter code assigned to your country. We accept US by default.

Step11. Configure normal user account

Normal user account is the account that you can use to ssh to the ESVA system. Since we added postman earlier, ESVA will create user named postman for us.

Step12 . Reboot the CentOS Linux

After you have completed the setup. A reboot to the system is required to take effect.

init 6

Note

If you make a mistake during the setup process, press ctrl-c to exit the setup program. You can then reconfigure using "esva-configure". For version 2 and above, ESVA can be reconfigured with ease.

Step12. Login to ESVA

After reboot. Login to the system

default password: password

Note: Please go to User Management and change your password after setup.
