![]() ![]() But you must first output it in xml-format with the following flag nmap 192.168.1.107 -oX result.xml You can run db_nmap and all the output will be stored in the metasploit database and available with hosts This might be a good way to keep your process neat and organized. And we can even integrate nmap into metasploit. We can do port-scanning with metasploit and nmap. To find the "man"-pages, the info about a script we write: nmap -script-help http-vuln-cve2013-0156.nseĬan be run by separating the script with a comma nmap -script scriptone.nse,sciprt2.nse,script3.nse 192.168.1.101 The syntax for running a script is: nmap -script scriptname 192.168.1.101 Here we will focus on it's ability to retrieve information that can be useful in the process to find vulnerabilitiesįirst locate the nmap scripts. Because nmap scripting is a really versatile tool that can do many things. This chapter could also be placed in Vulnerability-analysis and Exploitation. Nmap has a command to make the output grepable. Scan a range and output if a specific port is open ![]() Now you can input all those ips to nmap and scan them. Now let's sort out the ips from that file. cat ip-range.txt | grep -B 1 "Host is up" Ip-range is the output from previous command. We can use grep to output those IP:s.įirst let's find the IPs that were online. So let's say you find that 40 machine exists in that range. You can also specify a specific range, like this nmap -sP 201.210.67.0-100 The -sn flag stops nmap from running port-scans. You can then use nmap to scan the whole range. You might find that a site has several machines on the same ip-range. For example NSE does not work with grepable. Not all output works with grepable format. UDP is after TCP the most common protocol. ![]() So -sS can be read as scantype syn UDP scan In the flag I imagine that the first s stands for scan/scantype and the second S stands for syn. However it should not be considered stealthy anymore. This used to be considered stealthy before, since it was often not logged. It will send a syn, receive syn-ack (if the port is open), and then terminate the connection. "Stealthy" -sSīy adding the -sS flag we are telling nmap to not finalize the three way handshake. ![]() If you do not add any flags and scan a machine this is the type of connection it creates. If machine1 omits the last ack packet the connection is not made. This is basically what nmap does when it scans for a port. If machine2 responds with a syn-ack we know that that port is open. Machine2 send a syn-ack packet to machine1 That means: machine1 sends a syn packet to machine2 When one machine initiate a connection with another machine using the transmission-control protocol (tcp) it performs what is know as a three-way handshake. Okay, so a bit of the basics of Nmap and how it works. Then you can scan all of them with nmap at the same time. You just copy-paste those addresses and add them to a file, line by line. Now that you have gathered some IP addresses from your subdomain scanning it is time to scan those addresses. # Scan for version, with NSE-scripts and trying to identify OS Common ports/services and how to use themīroken Authentication or Session Managementĭefault Layout of Apache on Different Versions ![]()
