YazDHCP YazDHCP v1.2.4 [2025-Nov-21] - Feature expansion of DHCP assignments (increasing limit on the number of DHCP reservations)

I found reading or editing of these nvram entries tedious. So I used the following script to check the entries for accuracy, consistency and typographical errors.

echo ""
nvram get custom_clientlist | tr '<' '\n' | tr '>' '\t' | sort -u
nvram get dhcp_staticlist | tr '<' '\n' | tr '>' '\t' | sort -k 3,3 -u
echo ""

Me too (the tedious part), although I used a different approach and made a custom_clientlist generator, see here, with a few other interface options there too.
It’s primarily for those who prefer a more GUI approach to manage those lists.

The thing about your dhcp_staticlist line though, is that if you use YazDHCP they will have moved, so your second line will not actually show any results.

I found this out a while back by poking around in the files dnsmasq.conf.add and dnsmasq-x.conf.add, in /jffs/configs, post YazDHCP install; they show (resp):

addn-hosts=/jffs/addons/YazDHCP.d/.hostnames #YazDHCP_hostnames#
dhcp-hostsfile=/jffs/addons/YazDHCP.d/.staticlist #YazDHCP_staticlist#

addn-hosts=/jffs/addons/YazDHCP.d/.hostnames_br52 #YazDHCP_hostnames_br52#
dhcp-hostsfile=/jffs/addons/YazDHCP.d/.staticlist_br52 #YazDHCP_staticlist_br52#

addn-hosts=/jffs/addons/YazDHCP.d/.hostnames_br53 #YazDHCP_hostnames_br53#
dhcp-hostsfile=/jffs/addons/YazDHCP.d/.staticlist_br53 #YazDHCP_staticlist_br53#

So as above, I believe, when using YazDHCP, the DHCP_clients are now listed in /jffs/addons/YazDHCP.d/DHCP_clients.
That dir also keeps (I think) a saved copy of your original clients, in .nvram_dhcp_staticlist.

The issue is this:

• I noticed that the custom names (leftmost column) of devices that are offline (exclusively those ones) revert to New Device.
• I also noticed that when I try to add the name back (I use the same as the DHCP HOSTNAME) and click apply it does not apply.
• I also noticed that the correct names still appear to be in the custom_clientlist file.

WRT the YazDHCP webpage, the left-most column (i.e. "Client Name (MAC Address)" + icon) of the IP address assignment table is populated using a "clientList" array variable, which is created/generated by code from the "/www/client_function.js" file. This essentially means that YazDHCP has really no control over the functions & sources used to get the information necessary to populate the left-most column of the table.

Note that, AFAICT, most of the relevant data about which client is "online" or "offline" seems to be stored in files such as "/jffs/nmp_cl_json.js" and "/jffs/wlcnt.json", and that info is used (along with any custom icon info coming from the NVRAM custom_clientlist variable) to display the entries on the left-most column. This is particularly evident when the "Show Offline Client List" option in the drop-down listbox is clicked.

I have not dug any deeper or reviewed the /www/client_function.js code to know the minute details of how the data is initially obtained, collated, and stored in those files.

Just FYI.

WRT the YazDHCP webpage,

Just FYI.

Thank you @Martinski, I appreciate you having a look to see the source of it all the same.

The fact that @bennor was seeing a similar thing for long offline devices seemed a wee bit of a flag.

I do have several devices that haven't been activated in a while that do have New Device as the Client Name. Do wonder if there is something with how long a device has been offline before the Client Name reverts to New Device.
