协议的特定端口 Specific Ports by Protocols 默认情况下,端口扫描更喜欢枚举 TCP 端口的状态,但如果您想扫描 TCP 端口和 UDP 端口,请执行以下命令: 语法:nmap -pT:25,U:53 <目标> 端口服务名称 Port Service name 如果您不知道用于枚举的准确端口号,那么您也可以提及用于端口状态扫描的服务名称。 语法:nmap –...
获取开放指定端口的服务器列表(Get list of servers with a specific port open) nmap -sT -p 80 -oG – 192.168.66.* | grep open 1. 获取网络中所有存活的主机:Find all active IP addresses in a network nmap -sP 192.168.66.* 1. 不准确,该网络中还有3台存活主机192.168.66.100 192.168.66.106 19...
"Too many fingerprints match this host to give specific OS details" means that the probes are contradictory or too broad. For example in a NAT scenario, some port scans return the router information (e.q. Cisco iOS), some other probes return the real host specifications (e.q. Windows). ...
Checks may be limited by service category (eg: SPAM, PROXY) or to a specific service name. dns-brute Attempts to enumerate DNS hostnames by brute force guessing of common subdomains. With the dns-brute.srv argument, dns-brute will also try to enumerate common DNS SRV records. dns-cache-...
Start by using nc to listen on a specific port, with output captured into a file: $ nc -l 1234 > filename.out Using a second machine, connect to the listening nc process, feeding it the file which is to be transferred: $ nc host.example.com 1234 ...
Obviously this will take a large amount of time to complete the scan even if you are in a small (20-50 hosts) network. but it will give you the results. The better option would be to specify custom ports for scanning. Nmap allows you to probe specific ports with SYN/UDP packets. It...

Nmap transmitsTCPand UDP packets to a specific port during this type of scan, then examines the response. It uses a database of 2600 operating systems to compare this response, and it then returns details on the OS (and version) of a host. ...
# nmap -A address_or_addresses 4. Scan a specific list of ports (use ‘-p-‘ for all ports from 1 to 65535): # nmap -p port1,port2,...,portN address_or_addresses 5. Perform service and version detection of the top 1000 ports using default NSE scripts; writing results (‘-oN’...
To scan a single host for open ports, use the following command: nmap <target>。 To scan a range ofhosts for open ports, use the following command: nmap <target-range>。 To scan a specific port on a host, use the following command: nmap -p <port> <target>。 To scan a host for...
