Many systems and networkadministrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and both console and graphical versions are available.%prep%setup -q%build./configure --prefix=%{_prefix} --without-zenmap --without-nping --without-ncat --with-localdirs make %{?_smp_mflags} DESTDIR=$RPM_BUILD_ROOT%install[ "$RPM_BUILD_ROOT" != "/" ] && rm -rf $RPM_BUILD_ROOTmake install DESTDIR=$RPM_BUILD_ROOT%clean[ "$RPM_BUILD_ROOT" != "/" ] && rm -rf $RPM_BUILD_ROOT%files%defattr(-,root,root)%doc LICENSE%doc docs/README%doc docs/nmap.usage.txt%doc %{_prefix}/share/man/man1/nmap.1%doc %{_prefix}/share/man/*/man1/nmap.1%{_bindir}/nmap%{_datadir}/nmap%changelog
编译nmap RPM包
上传nmap源码文件到SOURCES/nmap-7.91.tar.bz2，执行下面的命令编译RPM包，过程如果没有错的话，会生成以下RPM文件：
$ ll RPMS/aarch64/
total 5676
-rw-rw-r--. 1 liuyl liuyl 5759680 Jan 27 17:44 nmap-7.91-1.el7.aarch64.rpm
-rw-rw-r--. 1 liuyl liuyl 47988 Jan 27 17:44 nmap-debuginfo-7.91-1.el7.aarch64.rpm
rpmbuild -ba SPECS/ultra-nmap.spec
-ba 既生成src.rpm又生成二进制rpm
-bs 只生成src的rpm
-bb 只生二进制的rpm
-bp 执行到pre
-bc 执行到 build段
-bi 执行install段
-bl 检测有文件没包含
验证RPM可用性
将nmap-7.91-1.el7.aarch64.rpm包上传到另外一台CentOS7机器上，执行如下命令进行安装：
# rpm -ivh nmap-7.91-1.el7.aarch64.rpm

安装成功，执行nmap命令进行端口扫描验证：
# nmap -n -Pn -T4 -sV -p22 10.10.17.143
