You can do a static lease that is tied to the MAC address but what a lot of users prefer is that they come into the office or lab the next day and that their device gets assigned the same IP address (if possible).
As we can see in the dhcpd logs that there is threshold that is defaulted as we'll show later. Whatever the threshold is set at, if the lease is younger than the threshold, it will keep the same lease. In other words, if the device goes to sleep or is powered off........
Be very careful about what filename you specify in dhcpd.conf if you get an error like this:
NBP filesize is 0 Bytes PXE-E23:Client received TFTP error from server.
If you specify "BOOTx64.efi" then the file had better not be called "BOOTx64.EFI" as it is case sensitive. It's really a case of th........
Virtualbox is a very powerful tool, but for some use cases it is less than optimal.
Say you are in a work, lab or other environment where you are not alone on the physical network and there could be overlap of IPs, but you need all of your VMs to be contactable from your host, VMs need to communicate with each other, and VMs need internet.
NAT Network will give you VM to VM communication and internet, however, it is buggy and unstable. It also doesn't allow host to VM co........
Just a quick note and warning is that if you are testing to see if EFIPXE booting works on a VM, MAKE SURE it actually works. For example Iinitially tested using my Distro's QEMU 2.5+dfsg-5ubuntu10.46 and ovmf BIOS firmware (OVMF supports EFI). However, I found on old versions of QEMU (like 2.5), EFIbooting with GRUB NEVER works so it may appear that you have made a mistake when everything is fine when you boot a physi........
By default your DHCP will often not work because it is not listening on any interfaces.
All you have to do is edit this file:
vi /etc/default/isc-dhcp-server
then find the "INTERFACES" line and add each interface that should listen:
INTERFACES="br0 enp0s10"

So you restarted your router/dhcpd server or for some other reason you wonder why DHCP is not working on any of your clients?You go and check that named is in fact running fine.
But then you check /var/log/messages and see this error for everything hostname:
named[1525]: error (broken trust chain) resolving 'min-api.cryptocompare.com/A/IN': 173.245.58.78#53
I've only ever seen this when the time on the server was off. It........
It has been a big pain for a long-time to install Windows from a Linux environment. I used to run a windows install server and it never worked right for some reason (the install would fail on most servers).
Before getting start be sure to setup your samba share so once you boot into WinPE you can mount the install for whatever Windows you want

It's really simple and just a matter of the following line within the subnet declaration.
deny unknown-clients;
See example below:
subnet 10.25.20.0 netmask 255.255.255.0 {
range 10.25.20.11 10.25.20.254;
deny unknown-clients;

The solution was to enable tftp in xinetd with "chkconfig tftp on".
See the troubleshooting below:

This is something I often setup for clients because it's very helpful for people in datacenters, this allows custom OS installs on demand, you can customize it more by using kickstart etc.. but here's a base I use before customizing more:
This little script below will install everything you need to get booting by PXE Linux.
It also assumes you set a local IP (be sure not to overwrite your existing IP) on eth0:0 (note the :0) as 192.168.1.10 and it........
