Output is important part of a scan because all gathered information will be shown. According to output next steps will be decided. In this chapter we will look nmap output features.
Grep is a tool used to filter text file with normal or regular expressions. Grep-able output will produce output which is very easy to use with Grep tool.
up to now we have used 3 output format one by one . In some situations we may need to get all of them for single scan. Nmap provides -oA to output in all 3 format just adding some extension to the end of files.
As we see after scan 3 files are created to save output.
如我们在扫描后看到的,创建了3个文件以保存输出。
gnmap is grepable output file
gnmap是可输出的文件
nmap is normal output file
nmap是正常的输出文件
xml is xml output file
xml是xml输出文件
仅显示开放端口(Show Only Open Ports)
While port scan there is different type of port status. Open, Closed, Filtered etc. . Nmap will provides all of this status information with port results. We can omit other than Open port status to make things clear.
