>>> Ensure that anonymous_enable=YES at \/etc\/vsftpd\/vsftpd.conf and start the<\/p>\n

>>> At Client Machine ,go to BIOS setting and change the boot device priority to<\/p>\n
keep “Network boot from xxxx ” at first position<\/p>\n
>>> The above Steps will facilitate you with Network Installation in Attended Mode<\/p>\n
i.e you have to physically do package selection and other stuff manually .<\/p>\n
To configure unattended Network Installation , follow these steps:<\/p>\n
1. Go to your PXE Server and check for kickstart file at \/root\/anaconda-
\nks.cfg, uncomment the following lines for Partitions: (Note: you can also edit this<\/p>\n
file with system-config-kickstart utility as per your requirements)<\/p>\n
clearpart –linux<\/p>\n
part \/boot –fstype ext3 –size=100<\/p>\n
part swap –size=2000<\/p>\n
part \/ –fstype ext3 –size=100 –grow<\/p>\n
save this file and copy it to \/var\/ftp\/pub.<\/p>\n
#cp \/root\/anaconda-ks.cfg \/var\/ftp\/pub (Please ensure required permission is<\/p>\n
granted for this kickstart file).<\/p>\n
2. Go to your Client Machine ,boot again and at boot option give :<\/p>\n
linux ks=ftp:\/\/192.168.182.137\/pub\/anaconda-ks.cfg and there you go , your<\/p>\n
Installation will be unattended .<\/p>\n
NOTE : You can completely make Installation unattended , meaning you don’t even<\/p>\n
have to specify the boot option (eg: linux ks=ftp:\/\/192.168.182.137\/pub\/<\/p>\n
anaconda-ks.cfg) . Even this can be automated to make your Installation completely<\/p>\n
INDEPENDENT from you . For this follow this steps:<\/p>\n
1. Edit \/tftpboot\/pxelinux.cfg\/default file and add the following lines :<\/p>\n
label linux<\/p>\n
kernel vmlinuz<\/p>\n
append initrd=initrd.img linux ks=ftp:\/\/192.168.182.137\/pub\/anaconda-ks.cfg<\/p>\n
2. Save the above file and Start your Client Machine’s Installation .<\/p>\n
ENJOY PXE!!!!!!<\/p>\n
