Dnsmasq 2.80 no ip obtain

[alberto280]

dnsmasq: started, version 2.80 cache size 150
dnsmasq: build options: IPv6 GNU-getopt DBus i18n IDN DHCP DHCPv6 non-Lua TFTP conntrack ipset auth DNSSEC loop-detect inotify dumpfile
dnsmasq-dhcp: DHCP, IP range 192.168.0.10 - 192.168.0.200, lease time 8h
dnsmasq: using server name 1.0.0.1 # 53
dnsmasq: using server name 1.1.1.1 # 53
dnsmasq: addresses / etc / hosts - 1 read


dnsmasq does not grant ip to the device I have this configuration:

no-resolv
interface=wlan0
dhcp-range=192.168.0.10,192.168.0.200,8h
dhcp-option=3,192.168.0.1
dhcp-option=6,192.168.0.1
server=1.1.1.1
server=1.0.0.1
log-queries
log-dhcp


in host this
/etc/host
192.168.0.1 gateway


in resolv this

# Generated by NetworkManager
nameserver 192.168.43.1



it still works but it doesn't give ip, do you have to put some ip to the interface or configure the ip in the network administrator?
If so, can you tell me how to do it?


Thanks

One way to do it is Debian's native ifup tool to bring up your nic with dhcp-client.
disable/mask systemd-resolved.service and NetworkManager.service.
Add

Code: Select all

supersede domain-name-servers 127.0.0.1; 

to /etc/dhcp/dhclient.conf.

I use unbound and use the above to get localhost assigned as the nameserver in /etc/resolv.conf and it works error free.

mi problem is the after run script hostapd "dnsmasq failed the address is already in use"
script mode monitor wlan2 but start dnsmasq dnsmasq failed the address is already in use
help

"dnsmasq failed the address is already in use"

that is bound to happen if port 53 is already in use.

Usually on a fresh start with dnsmaq and hostapd on my Espressobin Armbian, the service "systemd-resolved" is using port 53 preventing dnsmasq from starting. I remove this service "systemd disable systemd-resolved" and directly associate the DNS server in the systemd network file "/etc/systemd/network/10-wlan0" and that solves the problem.

could not dock server socket the address is already in use
Script start dnsmasq:

could not dock server socket the address is already in use

think you meant lock

[alberto280]

what I think it tells me is that the script is already using the socket and dnsmasq cannot start, what can I do?

What you can do is follow the solution shared by me in my first response in this thread.
