NMAP 6.00
-
Yes, 6.01 is out and I see that FreeBSD updated the port, but I haven't rebuilt the packcage/pbi yet, not sure when I will.
If I tell it to do a ping scan it says it's up for me. Not sure why it would be failing for you. It worked on both IPv4 and IPv6.
-
wondering how it picks interface? You would think it would hit the interface that connected to that network right??
But I do have 2 down vmxnet3 interfaces on my vm. Or wonder if could just be a VM thing? Will play with it more later. I think there was something in 6.0 about picking the wrong interface if in monitor mode? But I don't have any wireless interfaces?

Just noticed the nmap pkg commits at git and thought I'd offer a very quick note that the nmap versions I've used in the past can offer a root shell (since nmap runs as superuser).

so if I run nmap -e em0 it works just fine or if I run nmap –unprivileged it works.
Where is it getting that info from? It show both my wan and lan on em1
but clearly that is not the case

I have a vague recollection of hitting that on an older version of nmap (See here: http://forum.pfsense.org/index.php/topic,46058.msg242952.html#msg242952 ) - I'm not sure if it's an nmap issue entirely, or just on FreeBSD, or what.
I've always had better luck manually specifying the interface to use. If I get some time I'll add an interface drop-down (or perhaps source IP+Interface) to that, and to MTR while I'm at it since the code would be essentially identical.
Not sure if nmap 6.01 might help there, but the builders are tied up right now so I can't run off a new build just yet to find out. I doubt it'll help since it's been an issue on there for quite a while.
-
so I think it might be related to this
http://seclists.org/nmap-dev/2012/q2/920yeah a drop down on the gui to set interface would be helpful to work around the problem for sure.
From command line, knowing that its a bug can just always use -e flag, so not something that can not be worked through until they get it worked out. But very very strange! ;)
-
Just noticed the nmap pkg commits at git and thought I'd offer a very quick note that the nmap versions I've used in the past can offer a root shell (since nmap runs as superuser).
Not sure how that would matter. We pretty much consider all users as root anyhow, since the GUI has to run that way. Plus you can't exactly get an interactive shell from the GUI in PHP, and nmap isn't suid so if you had a normal user run it, they couldn't get a root shell anyhow.
Is there some way I'm not thinking of that is relevant there?
-
Bumped nmap to 6.01 today, and added an interface selector field to the GUI.
Also added an 'arp' scan type. Feed it a directly connected subnet, pick the corresponding interface, and it'll find anything in your subnet that will respond to arp.
I also added some input validation but that won't work quite right until a new 2.1 snap rolls out.
-
Bumped the package - and yup now with ability to pick interface the gui works!
