Fog DHCP service not run since fog 1.3

[patrice]

@george1421
I have took 10.x.x.x because have see tutorial with it, i don’t need 2 millions adresses, the fog is only on the dhcp server.
I try to install with 192.168.0.x range

Sorry,
I have to go to work, I leave you today
Thank you

@patrice I’m still reading through your config file.

I see your dhcp range is 10.0.0.10 10.255.255.254

But it appears you have computers systems at 10.0.2.2, 10.0.50.5, 10.0.2.15

This makes me think you have an already existing network, but no existing dhcp server (like on router or windows server)??

You have a router at 10.0.2.2, do you have other subnets? I’m just trying to understand how your network is designed so we can get the right answer for you.

I think your fog server is 10.0.2.15??

[george1421]

@george1421 On your fog server can you post the output of this command
ip addr show ??

[Wayne Workman]

@george1421 Once we have the network configuration, any issues with the dhcpd.conf file or other things will stick out.

@george1421
Hello George,
I want to try to remain simple in my explanation:
I had taken the configuration in a tutorial:
The fog server has 10.0.2.15, subnet mask : 255.0.0.0 gateway 10.0.2.2 DNS address 10.0.50.2
the DHCP server 10.0.2.2

I have nothing else on the network
I do not know if this is the best configuration
Here ip addr show:

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

@patrice said in Fog DHCP service not run since fog 1.3:

mai 23 10:51:21 shuttlefog isc-dhcp-server[28947]: Database file: /var/lib/dhcp/dhcpd.leases
mai 23 10:51:21 shuttlefog isc-dhcp-server[28947]: PID file: /var/run/dhcpd.pid
mai 23 10:51:23 shuttlefog isc-dhcp-server[28947]: Segmentation fault

I can reproduce this segfault error on my machine using your configuration. Give me a few more minutes and I am pretty sure we can figure out what’s wrong with it.

[Sebastian Roth]

It seems like the range is “just too big”. Changing the following line made it work for me:

range dynamic-bootp 10.0.0.10 10.0.255.254;

With that you still have more than enough IP addresses to play with. But please keep in mind that you ought to read and think a little bit about your network setup to not run into issue after issue in the long run. The output of ip addr show gave us another network interface eth1 which is within a completely different subnet. Don’t get things mixed up here…

[patrice]

@Sebastian-Roth
hello Sebastian thank you for you answer.
I’ve 2 network on this Computer, the first ( eth0) for fog server, and the second (eth1) for internet connection.
I changed the configuration line in dhcpd.conf with

range dynamic-bootp 10.0.0.10 10.0.255.254;
but the installation was aborted
when i launch ./installfog.sh (fog 1.4.0) i can’t change parameters since i install fog 1.2.0:

root@shuttlefog:~/fogproject/bin# ./installfog.sh

I worked with the OP via TV to help get things fixed.

Once I had an understanding of what he wanted we fixed the subnet mask from /8 to /24 on eth0 and then went and adjusted the dhcp.config file so that it matched eth0 of the fog server. Then the dhcp started OK. After that we upgraded fog 1.2.0 to fog 1.4.0. I checked the .fogsettings with the settings in the webgui and everything looked good when I disconnected.

I think this issue is now solved.

[Wayne Workman]

Well now I have to go and try this out myself…

The ISC-DHCP folks will be interested to know if this range size really is a problem.

[george1421]

@Wayne-Workman his original config file is below. Tomorrow I’ll post what I changed it to that allowed the dhcp server to start.

@george1421
I thank you, George for you help, for me it’s ok to solve this topic.
