DHCP Service Issue

george1421

Please review your isc-dhcp server configuration file. I’m suspecting that its not set. Refer to this example for the proper settings: https://wiki.fogproject.org/wiki/index.php?title=BIOS_and_UEFI_Co-Existence#Example_1

@mikec96 There is no IP address configured on the interface enp2s0?? What do you see when running ip link and ifconfig -a?

@george1421 Is the isc-dhcp server configuration file separate from the dhcpd.conf file? My dhcpd.conf file does not seem to have anything relating to the isc-dhcp section. Below is a copy of the file:

@Sebastian-Roth Apparently not, even though I specified 192.168.1.1 in the installation. I installed FOG while connected to the internet, then disconnected from the internet for use in an isolated network.

Here is the ip link result:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
    link/ether 70:e2:4c:68:0e:ca brd ff:ff:ff:ff:ff:ff

And here is the ifconfig -a result:

enp2s0    Link encap:Ethernet  HWaddr 70:e2:4c:68:0e:ca  
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

@mikec96 you need to get a static IP address defined for your fog server. That is the first part of the issue. Your dhcp server settings appear correct, so that isn’t the problem.

mikec96

@george1421 Thank you very much for your help! This might sound like a stupid question, but would I need to do that within Ubuntu’s “Network Connections” tool, or is that something I would need to set within FOG during installation or through the FOG web portal?

george1421

@mikec96 first step is the network connection tool. You need to make linux happy first then rerun the fog installer to get fog realigned with the new IP address.

mikec96

@george1421 I just set the static IP, and everything works beautifully now! I tested connecting another machine and performing a PXE boot as well. Thanks for your help!

george1421

@mikec96 Case closed now?

mikec96

@george1421 Yes, I’m all set. Am I able to mark the post as solved, or do I not have that ability?
