Confirmed, I just updated to a 3.0 kernel (3.2.0-24), and this problem presents on an old svn build of 5.61test5 with wlan0 in monitor mode: $ nmap --iflist -ddd Starting Nmap 5.61TEST5 ( http://nmap.org ) at 2012-05-26 19:37 CDT Fetchfile found /usr/local/bin/../share/nmap/nmap-services PORTS: Using top 1000 ports found open (TCP:1000, UDP:0, SCTP:0) INTERFACES: NONE FOUND(!) Reason: getinterfaces_dnet: intf_loop() failed ROUTES: NONE FOUND(!) Reason: getsysroutes_dnet: sysroutes_dnet_find_interfaces() failed If needed, I can do a debug build and step through this, but I'd rather not, if someone can identify the issue first.

In the second case (2) nmap 6.00 finds no routes (but works). In the last case (4) nmap 6.00 finds no routes and no interfaces. Other people with totally different hardware seem to have exactly the same problem: http://talk.maemo.org/archive/index.php/t-48673.html I hope my findings will help you to solve the problem. If you need further information, please let me know.
