nmap -p<port_range><target> 2. 单个端口 扫描目标主机的特定端口,例如扫描80端口: shCopy Code nmap -p80target_ip 3. 多个端口 扫描多个指定的端口,例如扫描80和443端口: shCopy Code nmap -p80,443target_ip 4. 端口范围 扫描一段连续的端口,例如扫描从80到100端口: shCopy Code nmap -p80-100target...
Host discovery: In host discovery, we find out which devices are up on the network, more specifically, the IP addresses of the devices. We do this by scanning a range of IP addresses with Nmap. Port scan: In port scan, we target one or multiple IP addresses on the network and find o...
Running a Quick Ping Scan using NMAP ByPaul Anderson/ October 3, 2016—Security Nmapcan make quick of work of doing a ping sweep of your network: [usr-1@srv-1 ~]$ nmap -sP 10.50.100.1-255 Starting nmap 3.70 ( http://www.insecure.org/nmap/ ) at 2005-06-13 15:50 PDT Host 10.50...
For example, you might want to scan 192.168.0.0/16 but skip any IPs ending with .0 or .255 because they may be used as subnet network and broadcast addresses. Nmap supports this through octet range addressing. Rather than specify a normal IP address, you can specify a comma-separated ...
Nmap done:1IP address(1hostup)scannedin0.06seconds Raw packets sent:1(28B)|Rcvd:1(28B) The above flags have the following meanings: -vv(Increase verbosity) -n(No DNS resolution. This speeds up our scan!) -sn(No port scan) -PE(Use ICMP echo request queries. This is what is displayed...
I usednmaplike this for years, but only recently grokked the manual to see what else it could do. Here’s a quick look and some of the more useful things I found out. 1) Scan a Network As its description implies,nmapcan scan a range of IP addresses. You can do this in a couple...
How to specify IP address and port ranges By default, Nmap will scan the top 1000 most commonly used ports, you can manually set a port range by using the “-p” flag and then specifying a range without spaces. Port ranges can be specified through comma-separated-values, hyphenated ranges...
Let’s say though that the IP address information was unavailable. A quick nmap scan can help to determine what is live on a particular network. This scan is known as a ‘Simple List’ scan hence the-sLarguments passed to the nmap command. ...
You can target a specific IP address or a range of addresses. nmap -sS 192.168.2.200 You can also designate specific port numbers for Nmap to check. nmap -p<ports> -sS <IP> nmap -p22,3389 -sS 192.168.2.200 Note that there is no space before the port numbers following the-pflag. ...
Specifying a range of IP addresses using a hyphen streamlines the scanning processes: nmap 192.164.0.0-255 Furthermore, Nmap provides options to enhance scanning capabilities. For instance, scan speed designations range from-T0to-T5, with higher speeds being more aggressive. The-voption increases ...
