포트를 채크하니 ==>
shell>nmap -p 1-6553 localhost
 Starting nmap V. 2.54BETA30 ( www.insecure.org/nmap/ )
Interesting ports on localhost.localdomain (127.0.0.1):
(The 6545 ports scanned but not shown below are in state: closed)
Port       State       Service
21/tcp     open        ftp
22/tcp     open        ssh
23/tcp     open        telnet
25/tcp     open        smtp
80/tcp     open        http
111/tcp    open        sunrpc
3306/tcp   open        mysql
5454/tcp   open        unknown
 그래서 5454 포트를 접속해보니 아래같이 ==>
shell>telnet localhost 5454
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
SSH-1.5-downund3r
 대체 이넘의 포트가 무엇에 쓰는것지? 어떻게 없에 하는지요?
