Howto get info about connected station from dumb accesspoints

Software SW tweaks
1

Hello I have configured mesh where omnia acts as mesh node and connect other 4 Dlink DAP-X1860 APs flashed with latest openwrt. It works perfectly, however I lost visibility who is connected and where. At mesh nodes I see only ? insted of names from DHCP. I would like to see translations at my APs and also have overview which device connect where.

Is there any way hot to achieve this? To transfer DHCP names to be shown in luci I found script way which is not perfect mainly when I must copy to several targets…

You can copy /tmp/dhcp.leases from your router to your access point.

I use xinetd:

On your router:

opkg update && opkg install xinetd

create script „/root/dhcp-list“
‘‘‘#!/bin/bash
cat /tmp/dhcp.leases ‘‘‘

and make it executable:
‘‘‘chmod +x /root/dhcp-list‘‘‘

Create following file „/etc/xinetd.d/dhcpleases“:

‘‘‘
service dhcpleases
{
socket_type = stream
protocol = tcp
port = 8000
wait = no
user = root
group = root
server = /root/dhcp-list
disable = no
type = UNLISTED
only_from = „your LAN network“
}

‘‘‘

Run:
‘‘‘/etc/init.d/xinetd enable
/etc/init.d/xinetd start ‘‘‘

Add following cron task on every AP:
‘‘‘* * * * * nc „Router IP“ 8000 > /tmp/dhcp.leases
‘‘‘

Pros:

  • easy to set up
  • Not much overhead
  • No extra software/script needed on APs
  • Cron entry is preserved during upgrades on APs

Cons:

  • No authentication, every LAN client can connect to Port 8000 on your Router an get dhcp list but there is no real critical information in it as every LAN client can scan LAN network on ita own and get the same information

Sorry for broken format, will fix it when I‘m at my laptop

Thank you this solves my first problem. And is there any service which would tell me which clients/mac addresses are currently connected? Ideally like HTML page. I know I can run arp at router manually.
