Research about load balanceing

Generally, load balancing is any method for evenly distributing processing or service requests across devices in a network.

We are going to focus on:
Layer-2 Load Balancing (bonding)

Layer-2 load balancing, aka link aggregation, port aggregation, ether channel, or gigabit ether channel port bundling is to bond two or more links into a single, higher-bandwidth logical link. Aggregated links also provide redundancy and fault tolerance if each of the aggregated links follows a different physical path. Link aggregation may be used to improve access to public networks by aggregating modem links or digital lines. Link aggregation may also be used in the enterprise network to build multi-gigabit backbone links between gigabit ethernet switches.The Linux kernel has the Linux bonding driver, which can aggregate multiple links for higher throughput or fault tolerance.

Webserver ready

Webserver in installed, the further configuration will be done later.

Set up few clients

I managed to set up in Virtual Box client´s

1. Ubuntu 10.10
2. Windows XP

Both installed with Wireshark, and working.

Web Mail Server

Vendor’s company wants communicate with employees, who are around world, safely. They don’t trust Gmail or yahoo, because information published in the internet few months ago says a lot of GMAIL or yahoo users lost their mails.

In order to implement Web Mail Server will be used:

• Ubuntu OS (www.ubuntu.com)
• MTA: Postfix (www.postfix.org)

 

Postfix is powerful, well established, but not too bloated, and is security conscious from the start.

• Pop/IMAP: Courier IMAP (www.courier-mta.org/imap/)

The Courier IMAP server is a fast, scalable.

• Database: MySQL (www.mysql.com)

MySQL is well supported for the sort of lookups required in a mail server

• Content Check: Amavisd-new  (www.ijs.si/software/amavisd/)

This plug-in required for blocking spam, virus checking and etc.

• Anti-Spam: SpamAssassin (spamassassin.apache.org)

This is powerful renowned spam fighting tool.

• Anti-Virus: ClamAV (www.clamav.net)

Free virus scanner that can be trusted and includes update daemon.

• Authentication: Cyrus SASL(www.imc.org/ietf-sasl/)

Secure and trusted cryptography technology for authentication of SMTP traffic.

• PostGrey (isg.ee.ethz.ch/tools/postgrey/)

Postgrey is an excellent little script to stop 99% of all spam. All it does is on first contact for specific from-to combinations, tells the sender server to try again in a little while, which most spammers cant afford to do. When proper servers try again after a few minutes it lets it through.

• Encryption: TLS (www.ietf.org/html.charters/tls-charter.html)

Secure and trusted cryptography technology for encryption of SMTP traffic. Not too be confused with client encryption technology like GnuPG and S/MIME. They are covered in the extend section.

• WebMail: SquirrelMail (www.squirrelmail.org)

Easy to set up php based web mail client. Platform has extensive plug-in selection.

• Platform: Amazon ec2 (aws.amazon.com/ec2)

It is designed to make web-scale computing easier for developers.

Pfsense i up and running

 

Tasks

Tasks for week 1:

• Do research about web mail server- Armandas
• Do research about load balance (blog diagram included) – Vasil
• Set up pfsense as router – Morten
• Set up few clients(Linuxs and Windows) – Bo
• Set up web server – Atilla

Make a blog entry, when your task is finished!!!!!!!! If you do not post anything, the team will have a meeting about kicking the slacker member out from this group!!

First idea of project

Requirements:

• Security network
• External Webmailserver
• Backup files to remote pc automatically
• External Web server
• Monitor backup process

Background story

The background story of the project is the following:

The system we are  about to construct is a vendor’s company network, with an external web mail server.  The company has employees all around the world, and they should be able communicate through a safe mail server.  Also, this company needs a web page  for advertising their activity. In order not to lose  important mails or important computers files, we will make a remote file server and backup the data  to another pc every day, automatically.
