NDMC.EDU.PH has moved!

September 3rd, 2009

We got disconnected from our ISP today, NDMC now has no Internet connection.

We have been with DCTech (old ISP) for more than 4 years and since they cannot fulfill our need for an upgrade from a 1.5Mbps to 4Mbps connection we decided it’s time to look for another ISP.  We signed-up with Globe INNOVE last June 2009 but are still waiting to be connected this month.  DCTech was generous enough to allow us a one month extension last August 2009 but did not approve our second request for an extension.

We had 8 public static IP addresses with DCTech and we used all of them to host servers for the following:

  • school website
  • email server
  • applications server
  • proxy server
  • perimeter firewall
  • internet gateway for offices

All major offices of the school are using e-mail and the Internet for research.  With my estimate, it would take around 2 weeks or more before Globe connects us.  Since we will be disconnected this month, I decided to move the three important servers on my Webfaction account so that we will have a minimal downtime.

Use open-source software for your servers

August 14th, 2009

We have been using open-source software for our servers at NDMC for the past months.  Being an educational institution on a tight budget, we cannot afford to buy licenses for commercial software so we choose to use open-source and free software, specifically GNU/Linux variants.

We were using Ubuntu 8.04 Long Term Support (LTS), which means it will be supported for the next five years (until 2013).

Then Bong, who has been experimenting with different variants of open-source server software suggested the following line-up:

  • pfSense – powerful Firewall, based on FreeBSD
  • Untangle – open source network gateway, web filter
  • eBox-Platform – domain controller, file server, print server, proxy server, mail server, and a lot more, based on Ubuntu 8.04
  • FreeNAS – file server, NAS server, based on FreeBSD

I added Proxmox Virtual Environment – an open-source virtualization platform to the list.  This allows us to create one or more Virtual Private Servers using just one computer.  This is our alternative to VMWare’s ESX.

The considerations for the above servers is also timely for our scheduled upgrade from 1.5Mbps to a 4Mbps Internet connection sometime next month.
