I would like to know if I can obtain ssh version using nmap of my external vps.
nmap -p 22 sV <domainname>
result:
22/tcp filtered ssh
Is there another nmap syntax so I can obtain ssh service version?
Just want to obtain the ssh service version of my external vps.
I tried alot of nmap commands but probably there's a struggle in-between like a firewall, which causes a filtered state. My own network is behind a DrayTek Device. Maybe a possible cause?
Thanks in advance!
The nmap option --badsum is able to provide insight about the existence of a firewall. A non firewall device that runs a full network stack will silently drop a bad checksum. In the case that your scan reaches an end device, you would expect to see the same result as your -sV scan. A firewall may offer a different reply to the --badsum.
The answer to your question regarding version, is that -sV is ideal, however -A may run some scripts that return useful information. You can also run --script=sshv1 or another specific script that is ssh related. More script options are here nmap scripts.
I am trying to list a shared folder I have on the desktop of a virtual machine. with these commands:
nmap -sU -sS --script smb-enum-shares.nse -p U:137,T:139 10.10.10.115
nmap --script smb-enum-shares.nse -p445 10.10.10.115
The combined output is :
Nmap scan report for 10.10.10.115
Host is up (0.00s latency).
PORT STATE SERVICE
445/tcp open microsoft-ds
139/tcp open netbios-ssn
137/udp open netbios-ns
MAC Address: 08:00:27:31:DB:FC (Oracle VirtualBox virtual NIC)
This is not the output I am supposed to get referring to this : https://nmap.org/nsedoc/scripts/smb-enum-shares.html
Why is it not listing the shared folder on the desktop ? I have set maximum permission to everyone for the folder.
Thank you !

Seems like a bug in nmap https://github.com/nmap/nmap/issues/704
You can try -d flag to run nmap in debug mode. I see the "SMB: Login as \guest failed (NT_STATUS_ACCOUNT_DISABLED)" error. But other utilites (e.g. softperfect network scanner) works fine without specific permisions on remote machine.
See documentation: smb-enum-shares. Use function add_account in smbauth module
For a quiz I must fill in the following question:
Which distribution of Linux is on the server. They give me only a ip adress "37.59.41.190". How can I check this external?
Use nmap command to find Operating System details, it's not 100% accurate, though,
nmap -O <ip address>
nmap runs different OS fingerprint check techniques.
I just installed nmap (never used it before). I want to see which machine on the network is listening to port 1234. How can I do that using the GUI of nmap.
nmap -v -A -p 1234 192.168.1.1-255 This command will scan your entire subnet
The officially supported (and included!) GUI for Nmap is Zenmap. It uses Profiles to choose common options, but the command line is clearly editable, as well. To get started, choose the Regular Scan profile, which removes the extra timing and scan mode arguments. Then, enter your target in the Target box. To scan a local network, you can use CIDR notation (e.g. 10.10.0.0/16) or octet ranges (e.g. 10.10.0-255.0-255).
To scan just one port, use the -p option with the port number. It is usually helpful to specify verbose output, too, with -v. Altogether, your command line will look something like this:
nmap -p 1234 -v 10.10.10.0/24
Then click the Scan button to begin scanning.
This worked for me
nmap -p 1234 -A -v 10.10.*.*
I have a list of remote machines in a text files. Can I know their MAC addresses using nmap ?
If you're using nmap, MAC addresses are only available if you're on the same network segment as the target. Newer versions of nmap will only show the MAC address to you if you're running as root.
i.e.:
sudo nmap -sP -n 192.168.0.0/24
Use snmp-interfaces.nse nmap script (written in lua) to get the MAC address of remote machine like this:
nmap -sU -p 161 -T4 -d -v -n -Pn --script snmp-interfaces 80.234.33.182
Completed NSE at 13:25, 2.69s elapsed
Nmap scan report for 80.234.33.182
Host is up, received user-set (0.078s latency).

In current releases of nmap you can use:
sudo nmap -sn 192.168.0.*
This will print the MAC addresses of all available hosts. Of course provide your own network, subnet and host id's.
Further explanation can be found here.
Some scripts give you what you're looking for. If the nodes are running Samba or Windows, nbstat.nse will show you the MAC address and vendor.
sudo nmap -sU -script=nbstat.nse -p137 --open 172.192.10.0/23 -oX 172.192.10.0.xml | grep MAC * | awk -F";" {'print $4'}
if $ ping -c 1 192.168.x.x
returns
1 packets transmitted, 1 received, 0% packet loss, time ###ms
then you could possibly return the MAC address with arping, but ARP only works on your local network, not across the internet.
$ arping -c 1 192.168.x.x
ARPING 192.168.x.x from 192.168.x.x wlan0
Unicast reply from 192.168.x.x [AA:BB:CC:##:##:##] 192.772ms
Sent 1 probes (1 broadcast(s))
Received 1 response(s)
finally you could use the AA:BB:CC with the colons removed to identify a device from its vendor ID, for example.
$ grep -i '709E29' /usr/local/share/nmap/nmap-mac-prefixes
709E29 Sony Interactive Entertainment
nmap can discover the MAC address of a remote target only if
the target is on the same link as the machine nmap runs on, or
the target leaks this information through SNMP, NetBIOS etc.
Another possibility comes with IPv6 if the target uses EUI-64 identifiers, then the MAC address can be deduced from the IP address.
Apart from the above possibilities, there is no reliable way to obtain the MAC address of a remote target with network scanning techniques.
Yes, remember using root account.

I'm not cool enough to be able to comment on a post.
so I guess I need to make a new post.
However the above recommendation of
"sudo nmap -sn 192.168.0.0/24"
is the best quickest method to get the all the MACs for the IPs on your
local network/vlan/subnet
What the OP doesnt mention, is the only way to get the MAC address
this way, you MUST use sudo(or other super user privs i.e. windows admin)
the command
nmap -sn 192.168.0.0/24 will discover hosts on your network, however will not return the MACs as you are not in SU mode of operation.
Just the standard scan will return the MAC.
nmap -sS target
With the recent version of nmap 6.40, it will automatically show you the MAC address. example:
nmap 192.168.0.1-255
this command will scan your network from 192.168.0.1 to 255 and will display the hosts with their MAC address on your network.
in case you want to display the mac address for a single client, use this command make sure you are on root or use "sudo"
sudo nmap -Pn 192.168.0.1
this command will display the host MAC address and the open ports.
hope that is helpful.
Not using nmap... but this is an alternative...
arp -n|grep -i B0:D3:93|awk '{print $1}'
