When when i switch on the tethering i am unable to find the dnsmasqleases file.

Android dnsmasq leases. I didnt find a possibility to get MAC. Im setting up a couple of Raspberry Pis on my routers DMZ dont worry all the ports are closed. To fix this set the dhcp-authoritative flag in dnsmasq.

The dnsmasqleases file is like a database for dnsmasq to know what address has assigned along with some other info. My router uses DNSMasq for DNS and so I added the MAC addresses. This module is inspired by the dhcpd-leases module however for the DNSMASQ leases fileThe dnsmasqleases file doesnt appear to have a formal specification but several confirmations of the format exist within the dnsmasq-discuss mailing list so I have opted to used these.

I will open a new question for android 10 kocj Feb 2 at 233. Dnsmasq keeps track of the DHCP leases it has in a file which is defined by the dhcp-leasefile config option. In Pi we the path of lease file is varlibmiscdnsmasqleases.

Android uses dnsmasq to do this. A structure of the file is pretty simple – each line is a summary of a connected user. For pi we can cat the IP address of named device by cat varlibmiscdnsmasqleases grep ClienDevNamecut -d -f 3 awk print 1.

What you can see here are my two OnePlus devices have apparently acquired additional leases for no obvious reason. In man page of dnsmasq there is a option saying -l –dhcp-leasefile Use the specified file to store DHCP lease information. Dnsmasq is free software providing Domain Name System DNS caching a Dynamic Host Configuration Protocol DHCP server router advertisement and network boot features intended for small computer networks.

Once you have booted the client machine check that it has an address and that it corresponds to the lease file for dnsmasq. From the machine running dnsmasq. Sudo cat varlibdnsmasqdnsmasqleases 1598023942 5254008ed5db 1921681100 server3 015254008ed5db 1598019169 5254009c5abb 1921681101 server4 015254009c5abb.

And the format of the file is. A lease which is long gone as far as dnsmasq is concerned and. I have a weird problem.

Usually it is placed at. Dnsmasq-leases Parses dnsmasq lease file declarations. If I add another computer to the network the old static settings get changed and they are even assigned a new ip address and lease.

So thinking now the problem is more general and Android related. So you can use a file to log it. Mkdir -p varrun cat datadnsmasqconf.

When its done just read dnsmasqleases file. But recently bought my wife the Hero and discovered the problem is also with that. Hostnames and IPs of the pis to the dhcp static leases.

Firstly you must have a rooted device. Im working with Clear OS 62 and Ive noticed if I configure computers with a static ip address configured using dhcp it does not maintain the static setting. To delete a lease from dnsmasq first stop dnsmasq.

My home network uses dnsmasq to provide DNSdhcp. The seen shows that. So there have been some changes.

My laptop has two network interfaces a wired one and a wireless. IrfanLatif Thank you for your quick repaly. In Ubuntu it is varlibNetworkManagerlease in some cases specially with dhcpd it is.

Android-9fe15ff2e8e65398 – leased until. I originally posted this in the Nexus One Forum. The summary has several fields including MAC.

Clone of dnsmasq for building in Android as as jni build. LineageOS 171 still has the DNSmasq executable. Dnsmasq ignores it until is times out and restarts the process.

According to sites here and here you cand assign static ip to a host as follows–dhcp-hostservername1921680199–dhcp-host0020e03b13afservernameinfinite–dhcp-hostaabbccddeeff1921680199. Now you need to serve DHCP leases.
