I've just redone one of my servers (K12LTSP 5EL). I have two NIC load balancing on bond0. I'm only using one NIC and have changed the appropriate files for this (see wiki). I've setup the dhcp server and it's running and handing out IP addresses to the non ltsp clients. Thin clients can't boot. Some just time out. Some give the error in the subject line. Below is my dhcpd-k12ltsp.conf file content. I'm not sure what I'm missing but it must be relatively simple... -- Mel Wade "The real problem is not whether machines think but whether men do." - BF Skinner <a href="http://www.melwade.com">http://www.melwade.com</a> # Sample configuration file for ISCD dhcpd # # Don't forget to set run_dhcpd=1 in /etc/init.d/dhcpd # once you adjusted this file and copied it to /etc/dhcpd.conf. # default-lease-time 21600; max-lease-time 21600; ddns-update-style none; allow booting; allow bootp; option subnet-mask <a href="http://255.255.255.0">255.255.255.0</a>; option broadcast-address <a href="http://10.0.9.255">10.0.9.255</a>; option routers <a href="http://10.0.9.1">10.0.9.1</a>; option domain-name-servers <a href="http://10.0.4.10">10.0.4.10</a>; next-server <a href="http://10.0.9.254">10.0.9.254</a>; option domain-name "<a href="http://ucastudent.net">ucastudent.net</a>"; option root-path "10.0.9.254:/opt/ltsp/i386"; option option-128 code 128 = string; option option-129 code 129 = text; option option-221 code 221 = text; shared-network WORKSTATIONS { subnet <a href="http://10.0.9.0">10.0.9.0</a> netmask <a href="http://255.255.255.0">255.255.255.0</a> { range dynamic-bootp <a href="http://10.0.9.100">10.0.9.100</a> <a href="http://10.0.9.253">10.0.9.253</a>; use-host-decl-names on; option log-servers <a href="http://10.0.9.254">10.0.9.254</a>; # trick from Peter Rundle <<a href="mailto:peter.rundle@au.interpath.net">peter.rundle@au.interpath.net</a>> # newer Macs if substring (option vendor-class-identifier, 0, 9) = "AAPLBSDPC" { filename "yaboot"; option vendor-class-identifier "AAPLBSDPC"; } # really old iMacs elsif substring (option option-221, 0, 5) = "Apple" { filename "yaboot"; option vendor-class-identifier "AAPLBSDPC"; } # Intel PXE elsif substring (option vendor-class-identifier, 0, 9) = "PXEClient" { # NOTE: kernels are specified in /tftpboot/lts/pxe/pxelinux.cfg/ filename "/lts/pxe/pxelinux.0"; } # default to an i386 BOOTP image else { filename "/lts/vmlinuz.ltsp"; } if substring (option vendor-class-identifier, 20, 3) = "ppc" { option root-path "10.0.9.254:/opt/ltsp/ppc"; } else { option root-path "10.0.9.254:/opt/ltsp/i386"; } } } # example configurations for specifying specific kernels to specific clients group { use-host-decl-names on; option log-servers <a href="http://10.0.9.254">10.0.9.254</a>; host boysdorm001 { hardware ethernet 00:E0:06:E8:00:84; fixed-address <a href="http://10.0.9.1">10.0.9.1</a>; filename "/lts/vmlinuz.ltsp"; option option-128 e4:45:74:68:00:00; option option-129 "NIC=3c509"; } host boysdorm002 { hardware ethernet 00:D0:09:30:6A:1C; fixed-address <a href="http://10.0.9.2">10.0.9.2</a>; filename "/lts/vmlinuz.ltsp"; option option-128 e4:45:74:68:00:00; option option-129 "NIC=ne"; } host boysdorm003 { hardware ethernet 00:D0:09:30:28:B2; fixed-address <a href="http://10.0.9.3">10.0.9.3</a>; # kernels are specified in /tftpboot/lts/boot/pxe/pxelinux.cfg/ filename "/lts/boot/pxe/pxelinux.0"; } # Apple Specific Settings # host boysdorm007 { # hardware ethernet 00:30:65:69:23:60; # fixed-address <a href="http://10.0.9.4">10.0.9.4</a>; # option root-path "10.0.9.254:/opt/ltsp/ppc"; # filename "yaboot"; # option vendor-class-identifier "AAPLBSDPC"; # } }
