I'm trying to understand if there are others computer into a unknown network.(i'm doing a penetetration testing in a private network)
After a nmap scanning and a Wireshark analysis i found the router candidate that has the ip addresses 192.168.193.85 and i want to know the list of all the ip addresses / machines under this subnet.
How can i know it ?
Thanks
Marco
Hi as you only want to locate the webserver in the subnet you can basically use the nmap command for the same
nmap 192.168.193.0/24 --open -p80,443
i am using 80,443 port which are basically used for web servers you can add other ports if you know what kind of the services they use.

Hi and ty for your reading,
I'm a beginner in virtualization and as part of a project I have to configure the IPs of a physical server and 3 virtual machines on Hyper-V in an internal network.
My question is, do I need to have a DHCP because I don't want to have a particular domain?
Which IPs and gateways do you advise me to use, considering my number of machines ?

You should use a subnet like 192.168.99.x with a mask of 255.255.255.0.
Enter your IP manually and you won't need a DHCP.
I am trying to map the notion of an openstack port to an IP abstraction. In the openstack documentation I see :
"A port is a connection point for attaching a single device, such as the NIC of a server, to a network. The port also describes the associated network configuration, such as the MAC and IP addresses to be used on that port."
So I assume a port must correspond to an IP interface (which in turn can map to a bridge, an ethernet interface or to one end of a veth link).
Is this a correct assumption? I am trying to figure out what IP abstraction maps to a loadbalancer port and I can't yet find it.
Thanks
Answering my own question (hopefully of help to others):
An openstack port corresponds to an ovs (or linnuxbridge) port that connects you up to a virtual network. A prefix of the port ID is used as a bridge name. You can create a port to a network and add it to a router.
I am trying to get IP address of Android Phone and it shows something like 192.168.0.0.But i need some thing like 10.0.2.0.Are both same?.Can anyone tell me what is the difference and How to get that address?
Thank you
Are you using AVD?
The AVD receives its network address and configuration on the private network from a DHCP server that is integrated into Virtual. The address which the virtual Device receives is usually on a completely different network to the host. As more than one card of a virtual device can be set up to use NAT networking, the first card is connected to the private network 10.0.2.0, the second card to the network 10.0.3.0 and so on.
It is highly unlikely that you have an IP with a 0 at the end because they are mostly used as the Network ID, especially with the 192.168.0.0 adress. The 10.0.2.0 and the 192.168.0.0 Adress are both IP Adresses that are in the private Range, so they are not public. I assume that you get your IP via DHCP so it depends on that DHCP Server what IP you will get. In the end of the day it doesn't really matter if you have an 10.0.xx.xx or a 192.168.0.xx Adress. Maybe I could help you a little more if you tell me why you need a 10.0.2.0 adress?
10.0.0.2 is an IP address found on many local computer networks, particularly business networks.Internet Protocol (IP) version 4 defines certain sets of IP addresses as restricted for private use (not available to be assigned to Web servers or other Internet hosts).
My friend wanted to connect to my computer using Remote Desktop Connection. But the problem is I am confused what my Ip address is.
My computer is connected to the internet via router via broadband internet network. My ip address is dynamic.
Here, my main purpose is not only the remote connection but also learning how dynamic ip connect to another pc.
I searched for ip address on Google. They show me an ip address. But I think it is not mine, it's related with the router or broadband network. I also find a WAN ip (it is different from that i found on google) on router settings. It did't work.
I used Team Viewer. It worked perfectly. But I want to do that manually because I am going to make a multiplayer game on GM8.
It will helpful if someone explain about ip and port forwarding.
Teamviewer is a great tool, but uses different techniques than what you plan to do. Teamviewer always uses an outgoing connection and use a mediator on the Internet to connect you and the other PC.
You should ask your Internet provider if he technically enables you to be reachable from the outside Internet. Often this is not possible at all, even if you configure your router the correct way.
When you ask this you can ask him if you have a static IP.
It seems you are not aware of basics of IP networking, so I'd strongly advise against trying this on your router as wrong settings would render it useless. But here's for your information how port forwarding and IP Address and dynamic DNS can be used to solve your problem.
Basically your ISP is likely to give you a router having an IP address. If this IP address is a global IP address, it is possible to connect to this IP from outside. How do you find out whether your IP address is global? Look for your WAN IP address setting. If it is in 10.x.x.x or 192.168.x.x range, it's unlikely to be global and in that case it might not be possible to connect to your computer from outside - without help of a third server (some kind of a registration server, where you connect and register your application). The Registration server would determine your globally visible IP address and then convey it to another Application who is interested in connecting to it. This is somewhat complicated to make it work (but if you intend to make a game - this is something you'd have to do regardless). This is mostly how software like TeamViewer would work.
If you have a global IP address - it means it can technically be reached from anywhere in the world. In that case you could use port forwarding to make things work for you. Port forwarding works basically as follows - You expose a certain port (on TCP) to external world - say 8000 and then you make a setting like following on your router.
<TCP>-<RouterIP>-8000 --> <TCP>-<Your LAN IP><Your application Port>
(You can find you lan ip using ipconfig on windows or ifconfig on Linux).
Now all connections coming to port 8000 would be directed to your application. You might want to do it on UDP as well and the protocol above would change. That is how you 'open' a few ports to be accessible from outside, configure them on your router and then run corresponding applications on your network.
There's another thing called dynamic DNS, where the IP address you use if it is dynamic (and global) can be registered with a Dynamic DNS server so that you don't have to know and remember the current WAN IP Address. But that can be for later.
Hope that helps.
What I want to do is simple: in a WLAN suppose I have the ip 172.16.0.10, and my friend has 172.16.0.9. The router has ip 172.16.0.1, I want that all the traffic b/w my friend and router passes through my pc(which I could analyze using wireshark.)
I suppose this can be done using 'route add' command in linux which I can execute in his pc and set the metric to a lower value, but as I am new to these commands I can't figure out the exact way. Please help.
Thanks in advance.
No need to use the route command because the IPs are in the same subnet. Routing applicable only if the 2 IPs belongs to different network. Just put the router's IP as default gateway.
