Installation woes: dhcp...Failed!

[george1421]

ok then lets confirm a few things.

You want FOG to be the dhcp and/or dns server for your subnet? Or do you have an existing infrastructure already in place? If you have an existing infrastructure in place AND/OR you are not doing PXE booting then you can skip the dhcp and dns configurations.

@Wayne-Workman Yes it does. Once the install/services are up and running we’ll take it off of the public facing IP and throw an internal IP on it.

[kbramhall]

@george1421 We are hoping to use PXE booting for these NAS devices using this FOG server to push a FreeBSD image over an isolated subnet.

[Wayne Workman]

@Arrowhead-IT in RHEL 7 / Fedora 19+ / CentOS 7 it’s just yum install dhcp

@kbramhall I know you said you weren’t behind a proxy - but we’ve heard/seen the issue you’re describing several times and more times than not it’s because of a proxy server / web filter / firewall higher up on the network that’s blocking access to repositories and mirrors.

Can you make double sure?

[george1421]

@kbramhall How about the part, do you need FOG to be the dhcp and dns server for the subnet where it will exist? I want to ensure that you REALLY need both dhcp and dns setup. Sorry for being picky here, but since this is your first time with fog I want to ensure we know how you need it setup.

Just so you know. The reason I chose not to use DHCP with FOG is because I had the mistaken assumption that FOG would automatically manage it in some way, or that the gui would have some control over it. It does not, you’ll be doing a bunch of manual configuration. It added some small configuration and did get it passing out ip addresses, which may be enough for you. But just be aware that you’ll likely have to do some more manual configuration of the DHCP. Not that that is all that hard nor undocumented on the internet, just wanted to make sure you’re aware.

@Arrowhead-IT Unfortunately that failed as well. I’m thinking there may be an underlying networking issue that I’ll work on with our networking team. Either way even if dhcp isn’t running on this server shouldn’t I still be able to get to http://xxx/xxx/xxx/fog ?

@kbramhall If fog doesn’t fully setup the first time then no it will not display the console login.

I would suggest that you go back from the beginning and select no for dns and no for dhcp. You can set those up later if you really need them. The packages are downloaded and installed then the database is configured then the apache settings are configured.

I guess now is as good a time as ever to say I’m working on an add-on that does just this.

I still feel this needs to be addressed.

@kbramhall Isolated subnet? Does it have an internet connection?

[kbramhall]

@george1421 I’ll give that a shot. Thanks

[kbramhall]

@Arrowhead-IT That is good to know. I am pretty sure all we need is to push IPs from a given IP pool to each of these devices.

[Tom Elliott]

@kbramhall All of this banter is going to go nowhere if the network you’re trying to install this thru does not have Internet access.

[kbramhall]

@Tom-Elliott If the FOG server is on-net with the devices won’t that make an internet connection unnecessary?

[Tom Elliott]

@kbramhall YEs, but not during the installation process.

The installer needs to download the files to do the install to begin with.

[kbramhall]

@Tom-Elliott The CentOS machine currently has internet access that’s how I downloaded the installer.

[Tom Elliott]

I’m confused.

Are you downloading the installer, then disconnecting internet?

[Tom Elliott]

Basically,

Does the internet work? Is it installing other packages, but failing to install dhcp?

I need clear concise answers.

Forgive my methods, but understand:

The CentOS machine has internet, it’s how I downloaded the installer, vs. The FOG Server is on Net with the clients, is not concise.

I’m assuming, at this point, the CentOS machine you are referring to is the same as your FOG Server?

[kbramhall]

@Tom-Elliott Sorry about that. Yes, the CentOS server is the what we’re running FOG on. I’ll just say FOG server moving forward to avoid any confusion. Yes it is successfully downloading other packages (httpd, php, php-cli, php-common, etc) but is not downloading the dhcp package. It has internet connectivity and will for the remainder of the setup. Once everything is up and running we’ll remove the internet connection and put it on an isolated subnet physically connected to the devices it needs to connect to.
