Solved iVentory on the same server as a different DHCP server (Pi-Hole)

[BrainStone]

Hi,

I have a server which is running Pi-Hole with DHCP enabled. I would like to run iVentoy on the same machine.

So I switched DHCP server mode to external (hoping it would disable the DHCP server ran by iVentoy) and clicked start. Which resulted in iVentoy telling me that it could not bind the port:

Code:

2023/06/30 20:34:42.135 [HTTP] API request: <{"method":"start_server","ip":"10.69.42.42","mask":"255.255.255.0","gw":"10.69.42.1","pool_begin":"10.69.42.200","pool_end":"10.69.42.219"}>
2023/06/30 20:34:42.135 [DHCP] DHCP port 67(UDP) is in use now.

What can I do so this setup works?

[longpanda]

Try 1.0.07

i am trying to run iventoy on synology NAS, The NAS has his own DHCP server, so on iventoy, i selected External, but when i try to start on the browser i am getting:

iVentoy start failed: DHCP port is occupied by another program now!

Using here iventoy 1.0.07

[BrainStone]

Yes. Sadly the same as hawkinf.

[longpanda]

1. Please upload the log.txt
2. Try as follows:
1) Stop the NAS DHCP Server
2) Start iVentoy in External DHCP Server mode
3) Start the NAS DHCP Server again

[BrainStone]

So I stopped my DHCP server, started iVentoy and the tried to start the DHCP server again, but that didn't work because iVentoy was binding the port:

Code:

~ # netstat -tupln | grep iventoy

since the iventoy provide the "next-server boot-files"
but Iventoy still need to responde dhcp request for "next-server boot-files" which would use UDP-67 and which is occupied by another program(your dhcp server) in your scene
this is not the bug .but I think dedicated DHCP server or dedicated Iventoy (not same IP)is better choise?

虽然iventoy 提供"next-server boot-files"
但是它任然需要回应DHCP请求.你的案例中你的67UDP被你的DHCP服务器占用了.所以iventoy 无法提供"next-server boot-files"
我觉得这个不是BUG.更好的办法其实DHCP服务器或者iventoy专用.

1.0.0.7 has fix the bug

[BrainStone]

I don't see why iVentoy would need to answer the requests if the already existing server can do so as well. Or why it would need to run on the default port

Tried 1.0.08 with no difference

You can test with latest 1.0.16 with DHCP ExternalNet mode.
Before that please refer this for details:
