Finally got LTSP to work. Right now, clocking in at 15 clients. Had to tweak /etc/X11/gdm/gdm.conf to up the maximum allowable sessions.

In a nutshell, here’s what I did:

• Installed Ubuntu Warty.
• Using the main repo, did apt-gets for SSH, NFS, TFTP, DHCP3, and libwww-perl, along with dependencies.
• Installed ltsp-utils; ran ltspadmin, then installed LTSP 4.1.
• Configured /etc/dhcp3/dhcpd.conf, /etc/hosts, /etc/hosts.allow, and /etc/exports.
• Had trouble tweaking DHCP (mainly the root-path and filename directives), but finally got it right.
• Fired up one client, setting it to boot through PXE first.
• Voila! Ubuntu login screen!
• Ooopss: used an i386 kernel so the 4-GB DRAM wasn’t recognized. Promptly got i686 kernel images.
• Tested on 15 clients first, but forgot to set limit on maximum sessions.
• Tomorrow, will boot on new kernel to see what happens. *crosses fingers*

Update: Photos are here.

• Configured Ubuntu Warty LTSP server.
• Had to manually point tftp root path in dhcpd.conf.
• Added NFS export entry.

• Got public IP from the net admin. Connected eth0 to the WAN switch. In /etc/network/interfaces:

  auto eth0
  iface eth0 inet static
  address x.x.x.x
  

• Modified /etc/apt/sources.list yet again, including the “Universe” Hoary repo.

• sudo apt-get update; sudo apt-get dist-upgrade

  Still taking too long. I think the 1-Mbps link is clogged. Too many users.

• Contemplating on using Apache Lenya. Looks promising, but I need to install Java, and maybe Tomcat. Lotta work ahead.

To access rich content such as video and images on the internet through a broadband connection, extension workers and farmers need not look further than the kitchen.

In an effort to provide wider access to information for Filipino farmers and extension workers, information and communication technology (ICT) specialists from the University of Southern Mindanao (USM) and the Philippine Rice Research Institute (PhilRice) have developed a “low-tech” solution to connect to the internet through Wi-Fi: using antennas made of pots and pans.

Came to work early, before 7:00 AM in fact.

• Added directory browsing restriction on PFI directories. Edited .htaccess:

  Options -Indexes

• Customized error messages on PFI.
• Configured Apache2 with PHP, SSL and Perl. MySQL doesn’t work, though.
