DHCP issue PXE-E51
-
I actually reinstalled the OS and FOG now I am running into a brand new problem with DHCP. The server is up and running but I keep getting error PXE-E51 and cannot seem to resolve it.

So what did you try so far? What kind of DHCP do you use? FOG isc-dhcp (default) or dnsmasq or windows DHCP server or an external router/firewall? Best if you could post a picture of the error here. Sometimes there are details on screen that help us solving things that you might not see.
-
So I installed fog on a brand new install of Ubuntu 16.04. I may have accidentally set fog to do DHCP and I am not sure how to change that. When I try connecting to the server over ethernet to image a machine or to make an image I get the error.
-
@slashdotpwn Please answer the questions and post a picture!
-
So I am not sure on which DHCP I set up I believe it was the default to be honest with you.
-
@slashdotpwn Looks like there is no DHCP server in that network at all. Edit
/opt/fog/.fogsettingson your FOG server and try to find the linedodhcp='N'. Just change that tododhcp='Y'and re-run the installer. -
I don’t even have a .fogsettings file.
-
@slashdotpwn Then simply re-run the installer and make sure you say
y(yes) when it asks you if it should setup DHCP! -
Okay now when I try to run the installer it says a previous version of fog settings is there. When I go to /opt/fog/ I see nothing.
-
@slashdotpwn In Linux files starting with a dot are “hidden”. So you need to use the
-aoption withlsto actually see it.ls -al /opt/fog/should show the file!In case you want to edit it using a GUI editor you probably need to fiddle with the file explorer options to make it show hidden files.
-
Okay I was able to use CHOWN to take control and edit the file. Rerunning the installer. Wish me luck.
-
@slashdotpwn On the console run
sudo chmod 666 /opt/fog/.fogsettings && sudo chmod 777 /opt/fog/(not nice but should fix this for you!) -
Even after changing the fogsettings file it skipped the dhcp setup
-
@slashdotpwn How do you run the installer? Best if you switch to the proper root account for running it. I’d say, remove the config ands start over:
sudo su - rm /opt/fog/.fogsettings cd /dir/where/fog/is cd bin ./installfog.sh -
Okay retrying the install now. Will let you know the results. Thanks for your patience by the way. I am usually pretty good with this kind of stuff.
-
When setting up the DHCP. It said no router address found. I am setting it up as a stand alone. What should I put in this case.
-
@slashdotpwn What do you mean by standalone? Don’t you have a router/gateway in your network to access the internet? Just put in this address when the installer asks you for it.
-
It isn’t connecting to the internet though. I am setting a static IP and connecting to it that way.
-
Okay so I found out that dhcp was turned off. It looks like my dhcpd.conf file is maybe wrong. It looks like it isn’t assigning ip addresses. I am leaving the office for tonight. I will be back in the morning to hopefully figure this out.
