Using Fog Server for mulitiple locations which has different subnets.
-
hey thanks for responding. heres my issue I have multiple subnets at different cities, I want to plug in my fog station on any local subnet and obviously change any ip settings on the fog server side that need to be changed in order for the clients to pxe from the fog server. If end up at a site and the subnet is 192.168.1.x and my fog server is still set at 192.168.100.0 (from the last site) wouldnt I need to change my fog server ip settings to match 192.168.1.x subnet so that the clients can see the fog server? also Im traveling to multiple sites so if plugging in a temp fog server is a quick way to upgrade to Windows7 then im ok with it and also my clients are all static IP’s no current DHCP so I will having the fog server supply temp dhcp when booting off pxe client.

Okay,
Then the first thing you’ll need to do is change your interface IP address to that of the subnet you’ll be working on.
The next parts you’ll have to change will be the Storage Management IP. (Make sure it’s set to the subnet you’re on).
Then you’ll have to change the IP addresses corresponding with your new system under (FOG Configuration/Other)->FOG Settings
Then you’ll have to resave your PXE file so it obtains the IP of your “new” setup for the subnet.

ok all images will be stored on the local workstation I have anointed my Windows7 Host>Oracle Virtual Box>Ubuntu Desktop x64 12.04>Fog 0.32 server, so I will need to change my ip host (Windows 7 box to local subnet im at) then change the ip to the Ubuntu (virtual pc) which effects the fog server.
now all the fog ip addressing that I need to change will all be in the “Fog Settings”? also how do I resave my PXE file for the new subnet? -
You have to change the Storage Management IP as well:
Storage Management-><YOUR NODE NAME>->IP Address
In FOG Settings you’ll most likely need to change:
FOG_WEB_HOST
FOG_TFTP_HOSTIf you use WOL you’ll also need to change:
FOG_WOL_HOSTTo change your PXE Default file:
FOG Configuration/Other ->PXE Boot Menu
That’s the easiest method, or you can edit the actual file:
Change the web= references to point to the new IP Address:
[code]/tftpboot/pxelinux.cfg/default[/code]

ok this is great info, I have navigated thru these areas you mentioned and I see all areas i need to change the IP Settings for…except FOG Configuration/Other ->PXE Boot Menu…I dont see any areas that have a ip change that need to occur in order to modify then resave…
-
ok I have changed the IP Address for all settings but im trying to figure out how to modify the “/tftpboot/pxelinux.cfg/default” I have navigated using Nautilus but its read-only, then i tried using VI but after pressing I for insert and started navigating thru the file i got tons funny looking characters so i closed out…How do I config the read-only file?
Update - i noticed the default file has root as read only and fog user as full access so i WinSCPd to the fog server as fog user with the password that is located in the TFTP Server settings under “FOG_TFTP_FTP_Password” I modified but yet host gets this error now:
PXE-E11 ARP Timeout
TFTP Cannot open connection -
you could always try [CODE]sudo gedit /tftpboot/pxelinux.cfg/default[/CODE] or the tried and true [CODE] sudo chmod 777 /tftpboot/pxelinux.cfg/default[/CODE] that will give all permissions to the file.

PXE-E11 ARP Timeout
TFTP Cannot open connection
this is what i get now…how to verify and test the fog tftp connection is working? -
It sounds like the PXE File can’t be found. Can you verify that the FOG_TFTP_HOST is pointing to the proper IP address, it should be your server which you changed the IP to.
-
ok we are finally getting somewhere…[B]FYI if clients are trying to use FOG as the DHCP server you need to modify this directory as well if your modifying your pre-existing FOG servers ip information for a different site location.[/B]
/etc/dhcp/dhcp.conf - this was the culprit for me, it still had the old ip address information and I also discovered I can narrow down the dhcp address scope here as well.
