Thank you Wayne Workman, it’s working now. also, thank you Quazz.
After copy instruction provided by Wayne Workman, changed boot to Grub style and command out /var/www/fog/lib/fog/BootMenu.class.php line 696 booturl/ipxe/bg.png it is now working perfect. This is awesome!

Yes, background image is different issue I have learned from previous problem. Again, thank you for your helping with this netmask and IP range problem. Without your help I probably go crazy, LOL.

@Wayne-Workman said in how to change netmask and ip range?:

@onenetwork there is, and it’s easy. I’m not at a computer at the moment - but when I am, I can easily construct a dhcpd.conf file that is exactly what you need - along with changes so fog 1.2.0 no longer overwrites the file. I’ll get it together sometime tonight for you.

Awesome!

so there is no way to fix client IP and netmask at all?
is there a file some where i can edit before update so it can bypass this? thanks all, i really need this to work.

@onenetwork On your server, what is the output of ip addr show ?

fog@ubuntu:~$ ip addr show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:0c:19:61:5c:da brd ff:ff:ff:ff:ff:ff

thanks

@onenetwork FOG should no longer overwrite your dhcp config with those settings to off. Is that not the case for you?

The submask value is located in the .fogsettings file, (along with other info such as routers and what not) which FOG will use to build the DHCP config (if you’re allowing it to control DHCP)

Sorry to say I can’t find anything related to submask or IP range locate in the .fogsettings files. I try to change routeraddress to 255.255.255.224 or 204.10.x.65(gateway) and it not working.
By the way I’m using fog server 1.2.0

@Quazz said in how to change netmask and ip range?:

@onenetwork You might have to set dodhcp to N as well.

Or you could alter the submask= value to try and let FOG handle it.

Still not work after edited dodhcp to “N”. What do you mean alter the submask= value, where and how?
Thanks

@Quazz said in how to change netmask and ip range?:

Edit /opt/fog/.fogsettings and set blddhcp to 0 so it doesn’t generate a DHCP file and your changes remain.

Btw 255.255.255.254 would make it so only one ip is on the entire subnet, just so you know.

Thank you Quazz for your answered. The problem is still there after I edit /opt/fog/.fogsettings and set blddhcp to 0. Everytime I reinstall it changed Client IP back to: 204.10.x.10 and netmask 255.255.255.0
My fog server is 204.10.x.68 and only able to use IP 204.10.x.66 to 204.10.x.192, I can’t use 204.10.x.10 as it was assigned to other switch. I hope someone could help.

hey guys, where can i change client IP range, say from 204.10.x.10 - 204.10.x.254 — to — 204.10.x.50 - 204.10.x.254?
also, where can i change netmask from 255.255.255.0 — to — 255.255.255.224?
please see the photo.
i use ubuntu 14.04 and edit the etc/dhcp/dhcpd.conf but it keep changing back to 255.255.255.0 from 255.255.255.224 everytime i reinstall. thanks in advance.
