Package: dnsrecon
Version: 0.9.1-3
Severity: normal
Dear Maintainer,
When using dnsrecon and requesting it to use the Google search (-t goo), it
fails due to an invocation to "urllib.urlopen(url)", which fails with an error
informing that there is no urlopen attribute in the module urllib, as can be
seen in the following example run. I would like to point out that the same
command did work on February 26th 2020, and stopped working on February 28th
2020, after some apt upgrade (however, I cannot provide which packages were
updated).
$ dnsrecon -d debian.org -t goo

Hi Raphael,
Thanks for looking into this. It seems it is an issue in Python3, and
there is even a pull request upstream to fix it:
https://github.com/darkoperator/dnsrecon/pull/107/files
Cheers,
Jonas.
