    I already have a separate DHCP server. How can I use it instead of dnsmasq.

    • Matei Cezar says:

      Yes you can. Make sure you also install tftp-hpa server and remove dnsmasq server is it’s already installed on your system. Instruct isc-dhcp server to pxelinux.0 file: filename “pxelinux.0”;

    Your approach does not support UEFI :-(
    I ended up using Serva.

  3. Naeem says:

    Is there any possibility to restrict IP allocation based on MAC address and avoid the ip range under /etc/dnsmasq.conf, my concern is if any VM boots off the same VLAN with PXE will pickup the IP.

    How can we avoid this?

  4. Naeem Ahmed says:

    Hi there, I am not able to boot from a local disk as an option 4.

    Do I need to add something there?

    HI i would like to ask how to set up Centos6.4 under RHEL7. I used to do with Centos6.4 it work properly, but under RHEL7 can;t work.
    label 1
    menu label ^1) Install CentOS 6.4 x64
    root (nd)
    kernel /kernel/centos6.4/vmlinuz ip=dhcp method=nfs:192.168.2.1:/install/nfs_share/centos6.4
    initrd /kernel/centos6.4/initrd.img

    why is this not working under RHEL7. It will told me mount error.

    • Matei Cezar says:

      I haven’t used nfs method so far! Check on the nfs server if the required ports are opened and the permissions set for nfs share.

  6. David Li says:

    Hi,
    I wonder why we need to install both tftp-server and vsftpd server. Is it because that the vmlinuz and initrd can only be downloaded using tftp and repo files can be download using vstftp server?

    Hello,

    I did everthing like in the post but DHCP does not give IP address to new computer on the network.
    Can any one help me please?

    • Matei Cezar says:

      On the server side: verify the firewall configuration, both input and output to see if it blocks dhcp transactions! Check dhcp log messages to see if a dhcp requests (discover, offer, request and ack) is made from client MAC address with the command: tailf /var/log/messages
      On the client side: make sure the NIC is instructed to obtain TCP/IP configurations through dhcp.

    With a built-in TFTP in DNSMASQ you don’t need to install a standalone TFTP.

  9. Daniel says:

    I allready have a DNS resolver running on a Pfsensebox and i was wondering if it possible to use the Pfsense DNS instead of DNSmasq

    • Matei Cezar says:

      If Pfsense DNS resolver and DHCP server has advanced options and can support adding entries for PXE and Tftp then you can go with it!

  10. Jesse Dale says:

    Excellent! I now have PXE boot with kickstart option on my centos7 server, and I’m going to write a small script to enable/disable vsftpd & dnsmasq when kickstart isn’t in use. Either that or I write a script to append then remove the necessary iptables to close those ports.

    One minor detail, the step above where you enter “chmod -R 755 /var/lib/tftpboot/” is missing, and only has a picture for it.
