Hey guys. I have issues every time when I attempt to change the IP address of fog. This time, I am not going to be changing the IP, only the subnet mask. I am coming from a 255.255.255.224 subnet and going to a 255.255.255.0. I tried to change it in the dhcpd.conf and restarted the service, but I kept getting a
[SIZE=6][B][COLOR=#333333][FONT=Arial][SIZE=24px][U][COLOR=#333333]PXE-E11 ARP Timeout Error[/COLOR][/U][/SIZE][/FONT][/COLOR][/B][/SIZE]

sorry…I searched for image id, and it wasn’t on the first page…also forgot I had asked this before.

Good morning all!

Had a quick question. I know that if you upload an image, and delete it, then upload a new image, the image ID will go up by design. I know that you are supposed to make changes and upload rather than deleting an image and stuff.

That was when I was in the learning process, and now that I know, is there a way to go into sql or anything and change it?

oops, nevermind…I changed the subnet mask under eth0 because I had a typo, but it didn’t accept the change…stupid Ubuntu haha…got it going now!

Alright guys, I changed the IP address of my FOG server, and I was doing it by memory. I edited something that I didn’t have too, and I am kind of stuck. I thought that I had it figured out, but looks like something still may not be right…Can someone look over this config and see if it looks right?

IP Address of FOG Server: 10.255.255.10
Subnet Mask: 255.255.255.224
Gateway: 10.255.255.1

dhcpd.conf:

[CODE]# DHCP Server Configuration file.

see /usr/share/doc/dhcp*/dhcpd.conf.sample

This file was created by FOG

use-host-decl-names on;
ddns-update-style interim;
ignore client-updates;
next-server 10.255.255.10;

subnet 10.255.255.0 netmask 255.255.255.224 {
option subnet-mask 255.255.255.224;
range dynamic-bootp 10.255.255.15 10.255.255.30;
default-lease-time 21600;
max-lease-time 43200;
option domain-name-servers 212.95.4.31;
option routers 10.255.255.1;
filename “pxelinux.0”;
}[/CODE]

I tried putting the subnet mask in dhcpd.conf of 255.255.255.254 and it said it was not within range…After I put it as 255.255.255.0 it went through, and computers can actually boot through PXE, however when I go to full inventory, quick image, or anything else that I have tried, it takes a while, and then it hangs @ Attempting to send inventory…

but it never asks me for values to fill out for some reason…something with the ip address somewhere isn’t right, and I am wondering if it because of something in the dhcpd.conf…idk…I am at a loss…everything else is working.

Nevermind…I made a wrong change in the dhcpd.conf.

Ugh! Had to change the IP address of the FOG server again. Not sure whats going on. I changed everything in the FOG WebUI, and changed the tftpboot/pxelinux.cfg/default, and changed /etc/dhcpd.conf and restarted the service…I can connect to the WebUI, ping the FOG server, but when I try to PXE, it does not find the FOG server.

I am very excited for .33! .32 has been great! It has made my life so much easier for deploying new PC’s, and refurbishing PC’s here at the office! Much better than any other cloning solution I have tried! Kudos to the developer! I am running uBuntu 10.4 on an old intel core 2 duo machine with a gigabit ethernet card & 4gb of ram. Has a 1TB HDD that has only a few images on it, but it is rock solid! I did have a problem with the latest kernel, but switching back to an older kernel was a breeze!

Thanks!

Well the thing is, we have to wipe using DOD…the wipe function built into fog is not DOD, or is it?

I would like to know how it would be possible to add dban as an option for PXE boot…I am running fog under an ubuntu 10.04 server, and I would like the option to wipe PC’s only for when we replace our PC’s

What about adding the ability to have fog change its IP address once it is cloned, and added to the domain, and snap-ins deployed? We have several locations on a WAN and don’t want it talking back to us.

Throwing out a suggestion…what about when you say have 1 image…you go through some problems with the image you built or need to add updates to it and such…you delete the image and readd it, and then the image id=7 instead of 1…the current build doesn’t automatically go back, it just keeps going higher and higher.

Thank you guys!

When you delete an image, and make a new one, even if you only have 1 image, it gives it the next higher ID number. How can you go and give it a different image ID of say back to 1 instead of 7?

Yeah, I came across that but wasn’t sure how to make it do what I want it to do, or if it would. I believe that it would, however I am not the best with linux lol. Therefore I am not sure how to make it do what I would like it to do.

NVM, Thanks for the help, I got it! It did require a restart of the service, and not just a server restart.

I restarted the server after making the appropiate changes…I have updated the DNS and I can ping by hostname and resolve the correct IP address of the FOG server. My FOG server is supposed to act as the DHCP server, so I am assuming that it is in the config somewhere.

still no go

I accessed the fog management through its new IP. I edited the dhcpd.conf, however in the Wiki, it only says to change Next-Server

Underneath I have
subnet 212.95.81.0 netmask 255.255.255.0 {
option subnet-mask 255.255.255.0;
range dynamic-bootp 212.95.81.10 212.95.81.254;
default-lease-time 21600;
max-lease-time 43200;
option domain-name-servers 212.95.4.31;
option routers 10.255.255.1;
filename “pxelinux.0”;
}

which has settings of the old IP Address. I will try changing that to reflect the IP address change and give that a whirl and post back.
