Is it possible in dhcpd.conf to ignore requests from a set of MAC addresses?
Something like this:
host vminstances {
hardware ethernet d0:0d:*;
ignore booting;
}

We are slowly starting to implement dhcp-snooping on our HP ProCurve 2610 series switches, all running the R.11.72 firmware. I'm seeing some strange behavior where dhcp-request or dhcp-renew packets are dropped when originating from "downstream" switches due "untrusted relay information from client"…

Howdy,
I have a client who has a WAN with 7 sites. At one site in particular, randomly about 4-5 clients do not get an IP address. The local gateway is a cisco 871 and relay's to a windows server in a Data Center running a valid scope for the subnet.
If I put in a cisco 1800 and configure a dhcp…

Context: I am running an installation with many small pools (3 address) and it does not seem to cope well when all three leases are taken. Nevertheless I see entries in dhcpd.leases-file whose end date has passed…

I want to assign multiple IPv6 to a server with multiple NIC.
As IPv6 RFC defines, each server has a unique DUID that can have one of the 3 formats (LL, LLT or enterprise). And each NIC has an IAID. So a request from NIC1 its the DUID and the IAID of the NIC1 and the request from NIC2 its the same…

Are there any good FOSS tools to do an audit of reserved IPs used in a Linux/UNIX ISC DHCPd environment? I'm trying to ensure that we do not have stale IP addresses reserved when old MAC addresses are pulled.

In the dhcpd.conf file for isc-dhcpd-V3.1.1, I have set up a vendor options space and defined several different options. I am able to use those definitions to send options from the server to the client in the vendor-encapsulated-options option (code 43).
However, the client is also sending vendor…

I have an existing LAN with a DHCP server already dishing out IP addresses.
For various reasons I cannot replace that server so it will still need to dish out IP addresses.
I've been experimenting with dnsmasq in proxy mode to provide PXE boot filenames.
Now I have dnsmasq chainloading iPXE ok,…
