Bugs
Like its author, Nmap isn't perfect. But you can help make
it better by sending bug reports or even writing patches. If Nmap
doesn't behave the way you expect, first upgrade to the latest
version available from https://nmap.org
. If the problem persists,
do some research to determine whether it has already been
discovered and addressed. Try searching for the problem or error message on
Google since that aggregates so many forums. If nothing comes of this, create an Issue on our tracker
(http://issues.nmap.org
) and/or mail a bug report to
<dev@nmap.org>
. If you subscribe to the nmap-dev
list before posting, your message will bypass moderation and get
through more quickly. Subscribe at https://nmap.org/mailman/listinfo/dev
. Please include everything
you have learned about the problem, as well as what version of
Nmap you are using and what operating system version it is
running on. Other suggestions for improving Nmap may be sent to
the Nmap dev mailing list as well.
If you are able to write a patch improving Nmap or fixing a
bug, that is even better! Instructions for submitting patches or
git pull requests are available from https://github.com/nmap/nmap/blob/master/CONTRIBUTING.md
Particularly sensitive issues such as a security reports may
be sent directly to Nmap's author Fyodor directly at
<fyodor@nmap.org>
. All other reports and comments
should use the dev list or issue tracker instead because more
people read, follow, and respond to those.
