dev -- Nmap development work, early release announcements, & bug reports


About dev
English (USA)

The Nmap dev list is intended to facilitate the
development of the free Nmap Security Scanner. It provides an
unmoderated forum for people to contribute ideas, patches,
suggestions, etc. We also discuss the pros and cons of proposed
changes to Nmap. Thus this list also serves as a sort of
developmental "steering committee". New (test/beta) versions of
Nmap may sometimes be released here prior to general availability
for quality assurance purposes.

Anyone hardcore enough to subscribe to nmap-dev should probably also
subscribe to the Nmap announcement list
(, a moderated list for
Nmap-related announcements.

This list is reasonably high volume (sometimes 10+ posts per
day). Archives are available at
Non-members can post, but such posts go through moderation to
prevent spam.

To see the collection of prior postings to the list, visit the dev Archives.
