  2. Contents • Introduction to LTS • Requirements • Benefits • Drawbacks • Configuration Process • Conclusion • References

  3. Introduction to LTS • Key technology used in Linux operating system that allows thin clients to boot from LTS server. • Thin Clients are the work stations that run few basic functions (i/o specially). • Thin Clients do not need physical storage media for booting process and no software too. • Collection of softwares turning normal GNU/Linux into terminal server • LTS server runs all the applications that are necessary for the clients to run and manage their function(heavy weightlifting, right?)

  4. Requirements Hardware Requirements Thin Client : • Processor 533 MHz • 32 MB RAM • PCI Video Card – 16Mb memory • Network Card (PXE network boot loader) • PS/2 mouse, keyboard Server: • Pentium 4 or Amd Anthlon, 3 GHz or better • 256 + (192 * Users) MB RAM • 80-120 GB hard disk or RAID system • 1 or 2 network cards • PS/2 mouse and keyboard

  5. Requirements contd.... • Softwares Following are the software requirements. • DHCP: For configuration of ip-address. • DNS server: Address resolution.(Not essential) • NTP server: Time synchronization.(Not essential) • TFTP server: For transferring the boot file. • XDMCP – opens desktop of server for clients • Port Mapper: • NFSrather than NBD (network block devices) in our case • No software in thin clients necessary.

  6. Benefits of LTS • Suitable for educational environments, and small scale business. • Low cost . • Central Administration and Management. • Security • Easy management. • Environment friendly

  7. Drawbacks • Single Point of failure. • Requirements for high server configuration. • High network load. • Unable to handle Intensive Audio/Video processes. • Latency might cause programs unresponsive.

  8. Configuration Process Following are the configuration Process: • Installation of Centos server. • Installation of LTSP –iso package. • Source : sourceforge.net/projects/ltsp • Mounted on: /mnt (mount –o loop /home/lns10a6/ltsp-4.1.0.iso /mnt) • rpm package installation: ltsp-utils(included in iso)

  9. Configuration Process contd.... Following are the configuration Process: • ltspadmin tool was run(lwpperl module should be installed) • Configure installer option was selected. • .... Next Slide =>

  10. Configuration Process contd.... Following are the configuration Process: • path name: file:///mnt (note URL format) was located. • Other options : Default

  11. Configuration Process contd... • Ltspcfg utility was launched

  12. Configuration Process contd... • After service set up: • Unmount ISO image from /mnt: umount /mnt • The configuration files of other required services are in following slides.

  13. DHCP configuration contd... • Configuration file for DHCP daemon: • DHCP listening in eth1 interface:

  14. Configuration Process contd... • NFS configuration file: what, and how you share? • Chroot /opt/ltsp contains scaled-down linux installation

  15. Configuration Process contd.. • Backbone of file transfer: linux initramfs filesystem image into RAM of thin client

  16. Configuration Process Contd.. • Host Configuration

  17. Configuration Process contd... • Hosts allowed for local services

  18. Configuration Process contd... • Multiple Client Hardware Platform support

  19. Concluding our work.... • Audio Settings Configuration was not performed. • Printer Configuration was not performed. • Understood NFS, DHCP, Portmapper, Run Level etc in brief • Last but not least, we haveLTSP server running.
