Annotation in the services file [/Quote] This is just a reference table for "service_name/protocol & port ". If you change the listen port of apache to 12345, then netstat-lp will see that port 12345 is listening If you add port 12345 in/etc/services, the preceding comment is "platinum", then netstat-lp will become the platinum service. If iptables is used for port DROP, iptables-vL will also see the same effect. This is defined in/etc/nsswitch. conf. files is used for service parsing. This function is affiliated with/lib/libnss_files.so.1 and/lib/libnss_files.so.2. Many people have misunderstandings about/etc/services. They think that if a row of data is deleted/added, they can turn off/enable a service. This is an incorrect concept. Let me talk about it here.
