General software structure

• following is installed in /tftpboot area on clon10 server:

linux-install/Centos5PAE_new/initrd.img
                            /initrd.img.backup
                            /vmlinuz
             /msgs/boot.msg
                  /expert.msg
                  /general.msg
                  /param.msg
                  /rescue.msg
                  /snake.msg
             /pxelinux.0
             /pxelinux.cfg/81394458 -> croctest1
                          /81394459 -> croctest2
                          /croctest1
                          /croctest2
                          /default
                          /pxeos.xml
         

Every client must has a file in /pxelinux.cfg/ area with the name containing IP address in HEX format, for example croctest1's IP is 129.57.68.88, so file name must be 81394458. It can be a symbolic link. The contents of the file for croctest1:

default Centos5PAE_new

label Centos5PAE_new
    kernel Centos5PAE_new/vmlinuz
    append  initrd=Centos5PAE_new/initrd.img root=/dev/ram0 init=disklessrc NFSROOT=129.57.167.16:/vol/diskless/Centos5 ramdisk_size=31809 ETHERNET=eth0 SNAPSHOT=croctest1.jlab.org NISDOMAIN=CCCHP acpi=force vga=0x305 vmalloc=256MB console=ttyS0,9600
