====== Kontrola po rebootu ======

Je třeba zkontrolovat síť:
  * <code>ifconfig -a</code>
  * vnitřní síť s klienty
  * nameserver:
    * pokud nemáme nameserver, zkopírovat ''resolv.chomsky.conf''
  

====== Instalace nového systému na chomském ======

===== Přístup ke stroji =====

  * lokální účet:<code>local-admin:Vele4,8n</code>

===== LTSP =====

==== Stará metoda ====

  * Nainstalovat server<code>apt-get install ltsp-server dnsmasq tftpd-hpa</code>
  * Vytvořit klienty<code>ltsp-build-client</code>
  * Spravit proxy dhcp<code>sed -i 's/ipappend 2/ipappend 3/g' /var/lib/tftpboot/ltsp/amd64/pxelinux.cfg/default</code>
  * Vytvořit ''/etc/dnsmasq.d/ltsp.conf''<file>#
# Dnsmasq running as a proxy DHCP and TFTP server
#
# See: http://www.thekelleys.org.uk/dnsmasq/docs/dnsmasq-man.html
#

#
# TFTP
#

# This might work instead of tftpd-hpa:
#enable-tftp
#tftp-root=/var/lib/tftpboot

#
# DHCP
#

# DHCP proxy on this network
dhcp-range=192.168.1.0,proxy

# Tell PXE clients not to use multicast discovery
# See section 3.2.3.1 in http://tools.ietf.org/html/draft-henry-remote-boot-protocol-00
dhcp-option=vendor:PXEClient,6,2b

# Better support for old or broken DHCP clients
dhcp-no-override

# Enable this for better debugging
#log-dhcp

#
# PXE
#

# Note the file paths are relative to our "tftp-root" and that ".0" will be appended

==== Nová metoda ====

  * Postupovat podle návodu na [[https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp]]: (pozor na ''locale'' - měly by všechny být UTF-8)<code>
add-apt-repository --yes ppa:ts.sch.gr
apt-get update
apt-get --yes --install-recommends install dnsmasq ltsp-server-standalone ltsp-client ldm-ubuntu-theme
ltsp-config dnsmasq
echo 'IPAPPEND=3' >> /etc/ltsp/update-kernels.conf
/usr/share/ltsp/update-kernels</code><code>
ltsp-update-image --cleanup /</code><code>
ltsp-config lts.conf
gedit /var/lib/tftpboot/ltsp/amd64/lts.conf</code>Ještě je třeba spravit DNS:<code>
echo DNSMASQ_EXCEPT=lo >> /etc/default/dnsmasq
service dnsmasq restart</code>a do lts.conf přidat<code>
DNS_SERVER="192.168.128.6 195.113.0.2"</code>
  * Tohle nestačí, dále je třeba do ''/etc/dnsmasq.d/'' přidat soubor ''ltsp.conf'':<file>

#
# Dnsmasq running as a proxy DHCP and TFTP server
#
# See: http://www.thekelleys.org.uk/dnsmasq/docs/dnsmasq-man.html
#

#
# TFTP
#

# This might work instead of tftpd-hpa:
enable-tftp
tftp-root=/var/lib/tftpboot

#
# DHCP
#

# DHCP proxy on this network
dhcp-range=eth1,192.168.128.100,192.168.128.150,12h

# Tell PXE clients not to use multicast discovery
# See section 3.2.3.1 in http://tools.ietf.org/html/draft-henry-remote-boot-protocol-00
dhcp-option=vendor:PXEClient,6,2b

# Better support for old or broken DHCP clients

# Enable this for better debugging
log-dhcp

#
# PXE
#

# Note the file paths are relative to our "tftp-root" and that ".0" will be appended

pxe-service=x86PC, "Boot from network", /ltsp/amd64/pxelinux
pxe-service=x86PC, "Boot from local hard disk"</file>
  * **Ovšem pozor na všechny možné soubory v ''/etc/dnmasq.d''**. V úvahu se berou všechny. A musí štimovat i s ''/etc/dnsmasq.conf''.
  * A podle [[http://www.linuxquestions.org/questions/blog/beachboy2-315980/ltsp-setting-up-from-scratch-35204/]] nejdřív zakázat kompresi NBD, předělat image pro klienty a pak tu kompresi zase povolit:<code>
cat > /etc/ltsp/ltsp-update-image.conf
# Configuration file for ltsp-update-image
# Do not compress the client image. Comment out the line below to enable again.
NO_COMP="-noF -noD -noI -no-exports"</code><code>ltsp-build-client
[service dnsmasq restart]</code>a nakonec zakomentovat<code>
# NO_COMP="-noF -noD -noI -no-exports"</code>

=== Konfigurace dnsmasq ===

  * ''/etc/dnsmasq.conf'':<code>
# Listen on this specific port instead of the standard DNS port
# (53). Setting this to zero completely disables DNS function,
# leaving only DHCP and/or TFTP.
#port=5353
port=0

# If you want dnsmasq to listen for DHCP and DNS requests only on
# specified interfaces (and the loopback) give the name of the
# interface (eg eth0) here.
# Repeat the line for more than one interface.
interface=eth1
</code>
  * ''/etc/dnsmasq.d/network-manager'':<code>#bind-interfaces</code>



==== Údržba ====

  * Po každé změně v konfiguraci provést<code>ltsp-update-image</code>
