inetd 슈퍼데몬 의 정의
- inetd 는 인터넷 서비스 데몬이며, 외부 네트워크의 요청이 있을 때 /etc/inetd.conf에 등록되어있는 내부 프로그램인
인터넷 서비스들의 데몬을 실행시켜 주는 역할을 한다.
즉 다양한 다른 데몬들을 제어 및 연결하는 역할을 하는 데몬이다.

| 경로(서비스 포트) | 설명 | |
| Windows server | C:\Windows\System32\drivers\etc\services |
C:\Windows\System32\drivers\etc\이하의 경로에는 리눅스의 /etc/hosts </etc/hosts.allow, /etc/hosts.deny>, /etc/services, /etc/protocol 등이 있음. 해당 디렉터리는 실무에서 주로 설정하는데 사용되는 경로이다. 그림1 참조 |
| Linux(RHEL/CentOS) | /etc/services | 해당 서비스에 대한 (연결지향형/비연결 지향형) = tcp,udp 서비스 포트에 대한 default 포트가 나와있다. 실제 해당 시스템 내에서는 안 쓰이는 서비스 포트도 있다. |

## Internet server configuration database
##
## Services can be added and deleted by deleting or inserting a
## comment character (ie. #) at the beginning of a line If inetd
## is running under SRC control then the "refresh -s inetd" command
## needs to be executed for inetd to re-read the inetd.conf file.
##
## NOTE: The TCP/IP servers do not require SRC and may be started
## by invoking the service directly (i.e. /etc/inetd). If inetd
## has been invoked directly, after modifying this file, send a
## hangup signal, SIGHUP to inetd (ie. kill -1 "pid_of_inetd").
##
## NOTE: The services with socket type of "sunrpc_tcp" and "sunrpc_udp"
## require that the portmap daemon be running.
## Also please use ## to designate comments in this file so that
## the smit commands can edit this file correctly.
##
## NOTE: When using IPv6 services, specify "tcp6" or "udp6" for the
## protocol. "tcp" and "udp" are interpreted as IPv4.
