Setting up Dnsmasq on Kali Linux. I'm attempting to configure a MITM attack on my home network. I have a USB Wireless Adapter (Alfa) that I'm using to host the AP through hostapd. When a device connects to the SSID being broadcasted via Hostapd, they need to be assigned an IP address via Dnsmasq's DHCP server. At the moment, the AP is up and running, but devices aren't being assigned an IP address as they should.
Wlan0 is the interface that I use to connect to the internet via my Home WiFi network.
wlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 10.0.0.22 netmask 255.255.0.0 broadcast 10.0.255.255 inet6 2601:1c2:1101:6dc:9665:9cff:fe1a:2282 prefixlen 64 scopeid 0x0<global> inet6 fe80::9665:9cff:fe1a:2282 prefixlen 64 scopeid 0x20<link> ether 94:65:9c:1a:22:82 txqueuelen 1000 (Ethernet) RX packets 11280 bytes 5273931 (5.0 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 8929 bytes 1481821 (1.4 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
Wlan1 is the interface that my Alfa is connected to, and I've assigned it the following IP address.
wlan1: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500 inet 192.168.1.1 netmask 255.255.255.0 broadcast 192.168.1.255 ether 00:c0:ca:84:74:ff txqueuelen 1000 (Ethernet) RX packets 184 bytes 30160 (29.4 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 207 bytes 35343 (34.5 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
Here is my dnsmasq.conf file configurations.
interface=wlan1 dhcp-range=192.168.1.10,192.168.1.250,12h dhcp-option=1,255.255.255.0 dhcp-option=3,192.168.1.1 dhcp-option=6,192.168.1.1 server=220.127.116.11 log-queries log-dhcp
And finally, my hostapd.conf file.
interface=wlan1 driver=nl80211 ssid=SerendipityFake channel=1
The wireless AP is working as it should, but something isn't working correctly to assign the IP addresses via DHCP. The following is the output that I receive when I start my DHCP server;
dnsmasq -C /etc/dnsmasq.conf -d dnsmasq: started, version 2.75 cachesize 150 dnsmasq: compile time options: IPv6 GNU-getopt DBus i18n IDN DHCP DHCPv6 no-Lua TFTP conntrack ipset auth DNSSEC loop-detect inotify dnsmasq-dhcp: DHCP, IP range 192.168.1.10 -- 192.168.1.250, lease time 12h dnsmasq: using nameserver 18.104.22.168#53 dnsmasq: reading /etc/resolv.conf dnsmasq: using nameserver 22.214.171.124#53 dnsmasq: using nameserver 126.96.36.199#53 dnsmasq: using nameserver 188.8.131.52#53 dnsmasq: using nameserver 2001:558:feed::1#53 dnsmasq: using nameserver 2001:558:feed::2#53 dnsmasq: read /etc/hosts - 5 addresses
I know that I'm getting the Discover requests when devices connect, because I can see the requests come across in Ettercap. Any suggestions on how to move forward from here would be appreciated.
