Technical logs - limit of DHCP log

AC1701 — Wed, 03 Apr 2024 23:47:06 GMT

Hi - i was hoping to retrieve the historic DHCP connected data from my routers technnical logs but it seems to be limited to 3 or 4 days of entries.

Is there anyway to get this for a longer period? I'm not sure whether BT might back this up to their servers or if its only held locally on the homehub.

Thanks

Why on earth would BT spend a fortune to back up the logs of millions of domestic routers?

The Hub's logs just wrap when full.

If is this the sort of thing you require on a regular basis for your own setup then might be time to get your own router.

Can you imagine if BT themselves backed this up and the overhead associated with that?!

@AC1701

Easier to use your own DHCP server with logging, and disable the one on the home hub.

Nice little Raspberry Pi project maybe 🙂

Exactly what I use, simply to implement 😉

Yeah can even do it with the PiHole project then benefit from the shielding also, I have a Pi 4 for that although I dont run the DHCP server from it so cant verify that, I indeed do have my own router (ER-X) doing most of my leg work.

I run the DHCP element, as the BT Home Hub DHCP server is rubbish. With the Pi-Hole one, you can name devices and manually reserve IP addresses and have a hosts list.

I love the local DNS, I've added all my stuff to that, the stuff that usually lived on my PC on the hosts file now is there for everyone to utilize 🙂
