DHCP server not starting - bakullama - 05-24-2020
I'm trying to set up the keexybox on a raspberry pi 3B+, from the installation script, and the dhcp server is not starting properly. I've turned off the dhcp server on my router, however it gives me the following message when I try to start the server from the console, while logged in as an admin:
Quote:Service dhcp start failed.
I've generated the dhcp file again, but no dice.
Any tips on how I can troubleshoot would be greatly appreciated! And please let me know if there's any more information I can provide.

Hi,
Can you check in "system settings -> DHCP" that DHCP ranges match with your networks? By clicking "Save", your configuration will be verified and it will show errors if something is wrong. Also Check if the "Enable DHCP" box is checked (DHCP won't start until it is not checked).

Done that, I've attached a screenshot of my config. It just shows a message saying "DHCP settings updated successfully. But DHCP reload failed." I also noticed the blue message, do I need to be using 192.168.1.0/24 instead of 10.0.0.0/24?

I don't have your screenshot
If the blue message shows you 192.168.1.0/24, the range must be in this network.
Try to start dhcp with CLI to get more details. Connect by SSH as root and run:
/opt/keexybox/keexyapp/src/Shell/scripts/init_dhcpd start
Have you done IP reservations for your devices? Also check if ip reservations for your devices are in one of networks (Connection settings -> devices).
Also, you can provide the content of generated conf files?
/opt/keexybox/dhcpd/etc/dhcpd.conf
/opt/keexybox/dhcpd/etc/dhcpd-reservations.conf (for privacy hide MACs before posting)
It is important to understand KeexyBox's network topologies: https://wiki.keexybox.org/doku.php/network_topologies. DHCP behavior depends on the choosen topology. DHCP may works on both networks (input and output) or just output network.
Also have a look at : https://wiki.keexybox.org/doku.php/system_settings_dhcp
Note that you can reboot the KeexyBox, the KeexyBox starting process do some clean up and reset permissions.

Sorry about the image, I thought I'd attached it but apparently not.
running /opt/keexybox/keexyapp/src/Shell/scripts/init_dhcpd start gives the following output

exiting.This seems odd, as I'm pretty certain I edited the range using the web gui, although it looks like it's getting different values for ip ranges.
my /opt/keexybox/dhcpd/etc/dhcpd.conf file looks like this:
Code:
# GENERATED BY KEEXYBOX WEBUI
# DO NOT EDIT THIS FILE
ddns-update-style none;
option domain-name "keexybox";
default-lease-time 600;
max-lease-time 7200;
log-facility local7;
class "external_host" {
match hardware;
}
class "internal_host" {
match hardware;
}
include "/opt/keexybox/dhcpd/etc/dhcpd-reservations.conf";
shared-network local_net {
# INTERNET ROUTER SIDE
subnet 10.0.0.0 netmask 255.255.255.0 {
option routers 10.0.0.1;
option domain-name-servers 10.0.0.5;
pool {
range 192.168.1.150 192.168.1.200;
allow members of "external_host";
deny unknown-clients;
}
}
# USER AND DEVICES SIDE
subnet 169.254.1.0 netmask 255.255.255.0 {
option routers 169.254.1.1;
option domain-name-servers 169.254.1.1;
pool {
range 169.254.1.10 169.254.1.200;
allow members of "internal_host";
allow unknown-clients;
}
}
}I notice that it has the wrong IP range again, despite what I specified on the web ui.
and finally, my /opt/keexybox/dhcpd/etc/dhcpd-reservations.conf looks like the following:
Code:
# GENERATED BY KEEXYBOX WEBUI
# DO NOT EDIT THIS FILE
host hostA {
hardware ethernet ##:##:##:##:##:##;
fixed-address 169.254.1.12;
}
subclass "internal_host" ##:##:##:##:##:##;
host hostB {
hardware ethernet ##:##:##:##:##:##;
fixed-address 169.254.1.10;
}
subclass "internal_host" ##:##:##:##:##:##;
host hostC {
hardware ethernet ##:##:##:##:##:##;
fixed-address 169.254.1.13;
}
subclass "internal_host" ##:##:##:##:##:##;
host hostD {
hardware ethernet ##:##:##:##:##:##;
fixed-address 169.254.1.11;
}
subclass "internal_host" ##:##:##:##:##:##;I wasn't sure whether I should be assigning IP addresses for the internal network (ie 169.254.1.0/24) or the original network (ie 10.0.0.0/24)
I ended up manually changing the range in the config file and starting the process from the ssh access, and it seems to be working now!
Thanks everyone for their help
RE: DHCP server not starting - paul - 05-25-2020
The "output" network is your "original" network before installing keexybox, and the input network is the new network for your devices.
In your case you should use following range for the output network (the second range to set on the DHCP settings page) :
10.0.0.150 -> 10.0.0.200
Be carefull by editing files directly. They may be overwritten by the Web UI. Let me know if you still have issue saving your DHCP config.
RE: DHCP server not starting - htryw3 - 05-27-2020
I too am having this issue, and I too get the same error when trying to manually start DHCP. I have manually edited the /opt/keexybox/dhcpd/etc/dhcpd.conf file to correct the DHCP range, but after clicking Next in the web UI, it writes it back to the incorrect values and breaks DHCP again. What's the status on getting this verified and fixed? Thank you.

It looks this issue happens during the configuration Wizard. I will try to reproduce it in my side. Meanwhile what you can do is Skip DHCP config and configure it after rebooting at the end of the Wizard.
After the reboot, check/configure the network (System settings -> network) and then the DHCP (System settings -> DHCP) and then reboot KeexyBox again.
RE: DHCP server not starting - benoit - 08-20-2020
It is a bug that is fixed now
You can fix it on your KeexyBox by following the instructions below :
- Connect over SSH to your raspberryPI
- As root run :
Code:
su - keexybox
cd /opt/keexybox/keexyapp/src/Controller/
mv ConfigController.php ConfigController.php.bak
wget https://raw.githubusercontent.com/keexybox/keexyapp/20.04.3/src/Controller/ConfigController.phpThe KeexyBox 20.04.3 version will soon be packaged specifically to integrate the fix.
