Port 53 is used by other service or you need root privileges.

Le port 53 est utilisé par un autre service ou vous avez besoin de privilèges root.

okay, thanks, but how can I close the listening service on the port 53 ?

Port 53 is used by other service or you need root privileges.

lsof -i :53 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME systemd-r 1445 systemd-resolve 12u IPv4 29095 0t0 UDP localhost:domain systemd-r 1445 systemd-resolve 13u IPv4 29096 0t0 TCP localhost:domain (LISTEN)

It's a DNS resolver. DNS resolvers always listen on port 53. how to fix it?

Answer:

udp 0 0 127.0.0.53:53 0.0.0.0:* 193/systemd-resolve

Decision:

sudo systemctl stop systemd-resolved

sudo systemctl stop systemd-resolved

Tried this, but stopping name resolution triggers another error upon launching evilginx2:

Is there a way around this?

You are missing SSL Certificate

Thanks. Turns out I had my DNS set up incorrectly and evilginx was not registering the SSL cert properly.

For anyone reading who is having similar issues, make sure your domain nameservers are pointing towards your evilginx server. Google Domains requires you to create registered hosts (ns1.yourdomain.com, ns2.yourdomain.com) and point them at your server's IP before you can add them as nameservers.

can you let me know how did you set up your dns I looked at various posts online but couldn't find anything i created my nameservers ns1.domain.com and ns2.domain.com pointed them to my server and added them as the nameservers after removing the default Name.com nameservers still can't get evilginx to work

Edit /etc/systemd/resolved.conf with a text editor (as root), e.g. open it with Nano console text editor:

sudo nano /etc/systemd/resolved.conf

And uncomment (remove # from the front of the line) the DNS= line and the DNSStubListener= line. Next, change the DNS= value in this file to the DNS server you want to use (e.g. 127.0.0.1 to use a local proxy, 1.1.1.1 to use the Cloudflare DNS, etc.), and also change the DNSStubListener= value from yes to no

This is how the file should look after you've made these changes (I'm using 1.1.1.1 as the DNS server here, which is the Cloudflare DNS):

[Resolve] DNS=1.1.1.1

FallbackDNS=

Domains=

LLMNR=no

MulticastDNS=no

DNSSEC=no

DNSOverTLS=no

Cache=no

DNSStubListener=no

ReadEtcHosts=yes

To save the file using Nano text editor, press Ctrl + x, then type y and press Enter

Create a symbolic link for /run/systemd/resolve/resolv.conf with /etc/resolv.conf as the destination:

sudo ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf

Reboot your system.

Port 53 should now be free on your Ubuntu system, and you shouldn't be getting errors like "listen tcp 127.0.0.1:53: bind: address already in use" anymore.

ENJOY
