      Description

      I have just installed FOG on a clean install of Ubuntu. Upon restarting Ubuntu, I noticed that my DHCP was not working. Based on suggestions previously given to me on the forum, I performed a few troubleshooting steps.

      First, I entered the following into the terminal:

      sudo systemctl status isc-dhcp-server.service

      and received the following result:

      isc-dhcp-server.service - ISC DHCP IPv4 server
  
Loaded: loaded (/lib/systemd/system/isc-dhcp-server.service; enabled; vendor preset: enabled)
   
Active: failed (Result: exit-code) since Tue 2017-09-05 09:57:22 EDT; 1min 43s ago

Main PID: 2087 (code=exited, status=1/FAILURE)

      I also entered this command into the terminal:

      sudo ip a s

      which returned the following:

      1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
   
	link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

      Any ideas about what could be going wrong? Thanks in advance!

        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

        Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

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

          Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

          Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG

            @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.

                  @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?

                    @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.

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