how to setup FOG server on Isolated netowork
-
How can I isolated my fog server from the internet without changing my setting on the fog server?
-
@cnbgeren Yeah it looks like your dhcp server isn’t running.
Since it appears you have a unbuntu server you might want to review this document. https://help.ubuntu.com/community/isc-dhcp-server

Where is that post you crated that documented the fedora 23 install. You had a dnsmasq section there that was pretty darn good, short and clear. You could almost dump that section into the draft link from above.
It’s in the Fedora 21 Article. I suppose I can literally copy these optional steps to the CentOS and Fedora 23&24 articles, changing yum to dnf where needed.
-
@cnbgeren Your fog server has a staticly defined IP address right??
-
ok I ran the following command nano /etc/resolv.conf but now I’m getting the this message: DO NOT EDIT THIS FILE BY HAND–YOUR CHANGES WILL BE OVERWRITTEN

I’m sorry I don’t understand what your askingYou ran the cat command to show the content of /etc/resolv.conf . That content only looks up internet names from the FOG server. Probably not what you want. You need to edit that file [/etc/resolv.conf] with a text editor (anyone that linux has. Two popular command line ones are vi and nano. There may be a gui based one like gedit that is available to you.) You need to change the entry
nameserver 127.0.0.1to something likenameserver 8.8.8.8save the file and then open a command window and key in ping www.google.com. That should now reply with the IP address and a ping response.

@cnbgeren simply edit that /etc/resolv.conf with vi or nano and replace 127.0.0.1 with either your ISP’s dns server or google’s {8.8.8.8)
-
had to take a picture of the command because I could not access internet with FOG server. also could not PXE boot while connected to my router or on Isolated network using switch. thanks for your help
-
@cnbgeren If dhcp is setup correctly and offering the required PXE information then, yes it should.
-
if I could ask another question. If the FOG server is running DHCP and is plugged up to a switch without internet access, I should be able to PXE using a laptop plugged up the same switch?
-
@cnbgeren cat since you are only listing the file
-
ok will do as soon I get home. would the command to retrieve the information be sudo or cat /etc/resolv.conf file?
-
@cnbgeren From your fog server you can’t ping www.google.com? If that is the case then please follow Sebastian’s recommendation to post the results of /etc/resolv.conf file. That file tells the fog server where to get dns information. If that is blank then you will need to add one line of text to that file.
Depending on your host OS you need to add this line if one exist
nameserver 8.88.8or
dns1=8.8.8.8

it’s not plugged up to isolated internet yet. Right now its plugged up to my router. everything was working fine until yesterday. then my another PC started using my FOG server as its DHCP server which caused all kinds of issue with my home network. Once I rebooted my router my issue was resolved with my home PC but now I can’t PXE boot to the FOG server or access the internet. I can ping 8.8.8.8 but can’t ping www.google.com any help would be great.
-
@cnbgeren Just for clarity, you have a fog server plugged into an isolated switch with only the target connected? If so then your fog server can not pull any updates or deployment status messages from the FOG Project web site. You will get the screen shot below. That is OK, message on an isolated network.
-
@cnbgeren Please post the contents of
/etc/resolv.confand/or/etc/NetworkManager/NetworkManager.conf
-
ok thanks, During the install of FOG software I took the defaults so DNS and DHCP were installed. for some reason, the FOG server worked perfectly over the weekend but now I’m not able to PXE boot to the server and
I’m not to able to ping www.google.com but I can ping 8.8.8.8 so I guess this is a DNS issue. here the error message on the server . do you think removing DNS could fix the error message below
