YazDHCP YazDHCP v1.2.0 [2025-Oct-12] - Feature expansion of DHCP assignments (increasing limit on the number of DHCP reservations)

[Martinski]

...
Attached is the System Log( I believe ) - I removed any MACs and External IPs and Other sensetive data was changed to protect the innocent!!!

While reviewing your syslog file, I noticed that you have quite a lot of the following entries:

... router dropbear[1517293]: Login attempt for nonexistent user from ....

I counted 58 such entries within the ~16 hours that your log covered. All indications are that all those attempts failed, so this is just an FYI in case you didn't know. I suggest making sure your SSH server is not accessible over WAN; but if that's how you want it, I'd strongly recommend disabling Password Login, changing the default SSH port, and using *only* strong SSH keys.

Just my 2 cents.

Just trying to fold in one other person who is not seeing the same results as bennor and I, would your advice (above) also apply to CaptainSTX issue regarding YazDHCP in that linked thread please?

I don't know since that user has not provided enough details and context for the problem, but it wouldn't hurt to run the very latest 'develop' branch version, and if the same problem continues, then provide clear screenshots and more details/context as the other 2 users have done.

If you have the time, I'd suggest running the latest YazDHCP 'develop' branch v1.2.1 version. See post #117.

Good news. Ok I don’t use YazFi; IIRC it’s not supported atm? Would you be open to uninstalling it and looking at the outcome? ie simplify it down to YazDHCP?

If you continue to get YazDHCP errors in the syslog *after* installing the latest v1.2.1 version and resetting the DHCP IP address assignments, would you please provide a copy of your /jffs/addons/YazDHCP.d/.staticlist file via DM?

You can redact the MAC addresses by obscuring only the first 3 hex values (e.g. XX:XX:XX:AB:CD:FF).
Also, please provide clear screenshots of your "LAN IP Address" and "Subnet Mask" settings.

no good results / fix.
the requested export and screenshots are in your DM

Thanks to a debug log provided by @Reef2009, I was able to find and fix the bug that was causing the malformed dnsmasq directives, such as the following:

set:lan
br1,XX:XX:XX:AA:BB:CC,set:XX:XX:XX:AA:BB:CC,192.168.1.2,HostName

The fix is now available in the latest 'develop' branch v1.2.1 version [ v1.2.1_25102001 ]

OK... What if I told you:
I woke up this morning and had a few devices that were not connected and they were because an AIMesh was not connnected... So I rebooted my Router and it all began working on 1.2.1!!!

 

[peepsnet1]

OK... I updated YazDHCP with "develop" just before rebooting and at the same time you posted this message...
That is what happened...

It works now!!

I rebooted and all my reservations were assigned correctly... At least to my Main Group. I do not have any guest assignments...

 

[peepsnet1]

Now I cannot login to the webUI...

This page shows up...

I enter my UN / PW and click Sign In. Then This...
Cleared Cache, tried different browsers, icongnito mode...

Reinstalling 1.0.10 and rebooting corrected the issue!!!!

Any Ideas??

 

[peepsnet1]

Ok... Sorry...

It appears the WebUI is going up and down every few seconds... I don't know what this is now...
I thought it was working but now I cannot get into my router at all... ill have to restore from a backupmon... Damn!!

I have to go to work so it will be tomorrow before I can report back

If you have SSH enabled on the router, SSH into the router to see if it can be accessed. One can then run top via ssh to see if that might provide a clue as to what the services are doing.

I just restored the router because I had to go to work and I needed my internet up for the family.

But I still did have SSH access and I considered topping it to take a look and see what was going on.

But at least I'm back to a known good state and to continue to debug the YazDHCP script.

 

[Reef2009]

Thnx @Martinski the fixed worked.
But I needed to uninstalled, reboot, reinstalled, Developer reboot, import DHCP Clients and ofcource with finalnreboot.
Thnx for your support!

Known issue with 388.10 and people using either Home Assistant or the mobile application. Disconnect either of these from the router for now.

Good to know... I'll drop the connection from both!

 

[peepsnet1]

Well... My login issues seem to have goin away with the above help.

And YazDHCP 1.2.1 seems to work then!!

I'll post more if I have issues.
