I want to identify all the computers on my LAN that have port 80 open. So I want to scan an IP range (192.168.0-255.0-255) and have Nmap print onto the screen all the IPaddresses it scanned that are accepting connections on port 80. How do I do this?
View 1 RepliesI scanned my home machine (windows vista) with Nmap, after disabling the firewall and all ports came back with the status as unknown (No Open Ports). Why no ports are showing as open?
View 3 Replies View RelatedI am trying to understand why when running nmap against a SonicWALL firewall at a remote location, the SonicWall firewall is saying that most of its 65535 ports are open? I know this cant be correct and remember reading about how some of these network appliances are setup this way to thwart off attacks.

i have old version for nmap:root@bt:~# nmap --version nmap version 5.35DC1 ( http://nmap.org ) i download new version, but before i install it, is there a way to upgrade the old one on my system? or need to un-install the old version and install the new version? i tried this:

I have a machine running Arch Linux (2010, I believe) with a 6TB RAID-5 array hooked up to a Highpoint RocketRaid 2320. I've been having issues with the RAID controller's drivers and the latest Linux kernels thanks to the driver not being open-source, and as a result I am migrating the system to Windows Server.Problem is that the 6TB disk originally was comprised only of an ext4 partition.I shrunk the partition down as much as I could, and added a NTFS partition in the empty space so I could start moving files. That went fine. Problem is that now I need to shrink the ext4 partition again, move files, shrink again, etc. The second run through resize2fs is taking way longer than the first pass.It seems to be getting stuck at pass 3:
[root@nar-shaddaa rc.d]# resize2fs -p /dev/sdb3 863000000
resize2fs 1.41.14 (22-Dec-2010)
Resizing the filesystem on /dev/sdb3 to 863000000 (4k) blocks.

I have been using Linux close to 2 years now. One thing that always bewildered me is audio support in Linux. These days I login to windows only for listening to music. After reading various blogs, i decided to give it a try in Linux with Amarok. There again I am facing a problem.
while i try to scan for music files it is not finding any files.
what I did is as follows:
Quote:
Setting --> configure Amarok --> collection --> scan
I have tried with mp3 .wma format files. While I try to add these files individually, Amarok is able to play those.
I am using Amarok 2.3.2 with KDE 4.4.5. Fedora - 12 is my flavor.
Given below is the log obtained with amarok -debug option

Got 3 computers connected by ethernet to a router modem. At this router modem only port 80 is forwarded to a web server (one of the 3 computers). Now I realized several times a port scanning attack displayed at interactive firewall of Webserver ( Apache at Mandriva LINUX ). Actually the message is port scanning attempt of heanet (actually this names are different mostly). I wonder how to figure out is this portscanning attack possible through port 80 or is the modemrouter (Draytek VIGOR) misconfigured, compromised or one of the other 2 machines (Windows) are compromised and attacking the server inside intranet?

View 9 Replies View RelatedIf you have been trying to compile & install the new NMAP 5.20 scanning utility as a 64 bit user, you may have run into some issues as I did...The compiler will halt when you attempt to 'make', saying that you need to recompile using -fPIC.The fix: "./configure CXXFLAGS=-fPIC CFLAGS=-fPIC LPFLAGS=-fPIC"then rerun "make".I hope this helps someone, as it took me way longer than it should have to get this going. Enjoy the new versions as it is supposed to have 10,000 updated OS detection signatures and new scripts!

NMAP scan for a range of individual IP's can be done using the '-' for example:

nmap does not update the scripts when launching Code: Select allnmap --script-updatedb from ANY debian i EVER tried.
I cannot find a workaround, just old bug reports that this is fixed.
Why, is this not ever working on debian. I expected an update-nmap-db command to be Debian conform but there is no such thing.
Running Wheezy with latest updates.
I have been trying to configure an MTA (sendmail) on a new Debian installation to receive system messages and local network mail. I have no need to fetch or relay mail outside my teeny LAN. The logs on the sending machine told me the mails were refused by the receiving (Debian Lenny) system. So I ran some quick nmap scans. From the sending machine, scanning the Debian machine:
PORT STATE SERVICE
22/tcp open ssh
111/tcp open rpcbind
From the Debian machine, running 'nmap localhost':
PORT STATE SERVICE
22/tcp open ssh
25/tcp open smtp
111/tcp open rpcbind
587/tcp open submission
From the Debian machine, running 'nmap debian' (this is a virtual machine named debian) :
PORT STATE SERVICE
22/tcp open ssh
111/tcp open rpcbind
Why the two different results? How do I get the scans to be the same so I can, eventually, configure an MTA?
Since I no longer have access to a spare machine to actually test this out on, I was hoping some kind soul might know the answer, or be willing to try it out for me. I'm trying to find out if the port scanner nmap can detect two different services which are sharing a single port. For instance, if I'd managed to set up, I dunno, a web server and an ftp server to both run over the same port, would nmap with version detection be able to detect both of them, or just one?

I am running a scan via nmap (nmap -sP) and the out put looks similar to this:
Nmap scan report for x.y.z.com (10.x.x.x)
Nmap scan report for 10.x.x.x
If it can resolve the hostname it does, if not it just spits out the IP. I would like to know the best syntax to use with cut, or awk, so that the only output is either the IP or IP - HOSTNAME.
I want to use this: [url]
However, I got an error because it required "http" and "shortport" lib for NSE.
I don't know how to install them. All I got is nmap shipped by slackware.
