Thanks for opening an issue!

I'd rather not click that link. Can you please paste in the text of the command that you ran and also the full text of the error?

Thanks!

Sure!

For some reason, your operating systems is not able to contact the default DNS server the tool uses (8.8.8.8).

Can you try running the tools with the -ns switch and provide your own DNS server?

Also, maybe try less than 100 threads. Start with 5 and go from there.

I have the same error on Kali VMware and DigitalOcean with my DNS server and low threads no. :(

Hmmmm...

Well, DNS enumeration is only needed for Azure. So let's try this to quickly test:

python3 cloud_enum.py --disable-aws --disable-gcp -t 5 -k test

That will use the built-in 8.8.8.8 DNS server. If it fails, you can then do this:

dig test.com @8.8.8.8

Do they both fail? Then, you can try them again with another nameserver:

python3 cloud_enum.py --disable-aws --disable-gcp -t 5 -k test -ns 1.1.1.1
dig test.com @1.1.1.1

If you consistently get failures from both dig and cloud_enum, then you need to troubleshoot your access to the DNS servers you are providing. If you are getting only errors from cloud_enum, then let me know.

Also, does the error come up right away when it gets to DNS? Or does it make some process at all before crashing?

Thanks!

That works without AWS. Thank you!
