Contents

  • Server
* Pentium IV, Intel Core 2 Duo, AMD dual.
* 500 Mb of RAM + 80 Mb * number of thin clients
* 1 or more network cards
  • Thin clients:
* Almost Pentium I 166 (recomended > Pentium II 350)
* Almost 64-128 Mb of RAM (TCOS can run with 24 MB ussing NFS and local swap)
* Network card (recomended 100Mbps and PXE support)
  • Network:
* Almost one network 10/100 Mbps switch, gigabit will be better, and if you have more than 20 thin clients a scheme like this:
Network scheme with 2 net cards

Image:Button ok.png TIP: You can use any other kernel but these are recomended, and perhaps deprecated versions

Image:Messagebox info.png NOTE: There isn't any reason to use in server same kernel version that thin clients use, please use *-686 or *-k7 kernels in server, that have better perfomance and support more RAM

Install packages

Image:Messagebox info.png NOTE: TCOS images usually should be 32bits, if your server is installed with other architecture (for ex amd64)

See: Install/OtherArchs

First of all you need to import my GPG key and add one line to sources.list,
you can see all avalaible mirrors in Packages section

Install with apt-get, aptitude or synaptic: 

apt-get install tcos

Image:Button ok.png TIP: Perhaps you need to create /tftpboot dir and exec: dpkg-reconfigure initramfs-tools-tcos after installing, TCOS will never create non standard directories

tcos metapackage will install some tools:

  • dnsmasq OR dhcp3-server
  • dnsmasq OR atftpd
  • syslinux
  • xfs
  • ....


Next we have to install unionfs and squashfs modules, in newer distros isn't necesary because default kernel have them, but in some old versions we can try to install precompiled modules: 

apt-get install tcos-extra-modules-$KERNEL_VERSION

or build: 

apt-get install build-essential module-assistant linux-headers-$KERNEL_VERSION
m-a -t -k /usr/src/linux-headers-2.6.18-5-486/ build unionfs squashfs
m-a -t -k /usr/src/linux-headers-2.6.18-5-486/ install unionfs squashfs

Image:Button ok.png TIP: If you want to use another kernel you can change in /etc/tcos/tcos.conf


Optionally we can install some other tools:

  • x11vnc
  • freenx
  • alsa-base alsa-utils
  • pulseaudio pulseaudio-utils libflashsupport
  • paman pavucontrol pavumeter
  • ltspfs-client
  • ltspfs-server
  • tcos-server-utils
  • tcosmonitor (Remote management support)
  • tcosconfig (GUI Wizard to build images)
