HowTo setup Local DNS/DHCP Plugin

I do what votdev say here: OMV3.0 update problem

But still same error.

So my first problem is that i'm not able to install.

The only issue that this plugin right now is the DNS.
The installation is fine for me.

If I put in the parameters in extra option, the DNS stop working immediately.
With or without the port=0, same result.

port=0
dhcp-range=192.168.1.0,proxy
pxe-prompt="Press F8 for menu", 20
pxe-service=x86PC,"PXE Boot-Server",pxelinux
resolv-file=/etc/resolv.conf

No it didn't.
I figured you're busy, so I don't bug you about it.

I see you discusion here and i have test dnsmasq plugin too.

So the same problem with no dns with port 0 or without port 0.

My solution was to remove line "resolv-file=/etc/resolv.conf". Now pxe will now find in my network.

tftp has a ping timeout but without a pxe image (the pxe from omv-extras.org is offline) i can't test it.

Thanks. tftp running well. My "Test" will show up.

Now i am happy

Again for the other user here:
my "extra" entry on dsmasq is:

dhcp-range=192.168.0.0,proxy
pxe-service=x86PC,"PXE Boot-Server",pxelinux

Good to know.
You can download the ISO from another source like Clonezilla without waiting for the omv-extras to be fixed.
I'm using NFS, I test it tonight.

Thanks.

The dnsmasq is working good now.
I got this error message when I tried to pxe boot the UBCD.

Failed to load COM32 file ubcd-5.3.6/boot/syslinux/menu.c32

I re-downloaded the image, and used a separated image from UBCD site, but error persist.

Putting some feedback here for @ryecoaaron since I don't want to clutter the ZFS plugin thread with dnsmasq plugin stuff, but I found a bug I believe. This is running OMV 3.0.59 on a Raspberry Pi (Pi 2 if it matters).

I went in and started adding static entries, and decided to clean up the CNAMEs while I was at it to make it quicker. The second entry I added I skipped the CNAME altogether, added another successfully (with a CNAME), and on the fourth entry tried to add one from a static lease, also without a CNAME, and got the following error:

The configuration object 'conf.service.dnsmasq.entry' is not unique. An object with the property 'cnames' and value '' already exists.

Details of this were as follows:

Error #0:
exception 'OMV\AssertException' with message 'The configuration object 'conf.service.dnsmasq.entry' is not unique. An object with the property 'cnames' and value '' already exists.' in /usr/share/php/openmediavault/config/database.inc:480
Stack trace:
#0 /usr/share/openmediavault/engined/rpc/dnsmasq.inc(239): OMV\Config\Database->assertIsUnique(Object(OMV\Config\ConfigObject), 'cnames')
#1 [internal function]: OMVRpcServiceDnsmasq->setEntry(Array, Array)
#2 /usr/share/php/openmediavault/rpc/serviceabstract.inc(124): call_user_func_array(Array, Array)

#4 /usr/sbin/omv-engined(516): OMV\Rpc\Rpc::call('Dnsmasq', 'setEntry', Array, Array, 1)
#5 {main}

This happened when I tried to add a static entry manually as well, without the CNAME. As long as there's a CNAME, it works.

Other than that, everything is working fine for me; I've got the plugin configured and working to provide DHCP and DNS for four different subnets with no issues at all other than this CNAME thing. I could wish for an easier way to import static entries in bulk, but that's sort of a one-and-done thing that I just have to work my way through.

I really appreciate you porting this "damned plugin", ryecoaaron. Anywhere I can make a donation for it? Can't offer much, but having this ported makes managing dnsmasq in a complicated environment so much more convenient.

3.1.2 in the testing folder. It only checks for a unique cnames or name if there is something in the field now. I think that will fix your problem.

Got it, will test it later today. I had something blow up spectacularly last night for some reason; after putting in a bunch of static entries, DNSMasq was failing to start, and from what I could tell it was segfaulting. I backed up the config files that omv-mkconf dnsmasq generates and put my manual config files back in and it fired up right away.

I haven't had a chance to go through the configs and try to identify what might be causing the issue because it was after midnight and I just needed it working in the morning for my daughter, but I should have time today to break things.

Not sure it's related - I don't know how it could be - but I tried a reboot while dnsmasq wasn't working and EVERYTHING went sideways. Was getting HTTP 500 errors on the web interface and "connection reset by peer" on SSH attempts. Ended up taking the Pi to a keyboard and monitor and it booted to command line so that's when I swapped the dnsmasq configs.

(FYI, not sure if it really matters but it lets you match the CNAME and the primary name, so if hostname is 'foobar' and you put additionals as 'foobar' it takes it with no issues.)
