如何关闭一端口？
比如关闭端口（765）
Come back to recall myself...

大家帮我看看这些端口好吗?
Port State Service
22/tcp open ssh
111/tcp open sunrpc
1024/tcp open kdm
6000/tcp open X11
请问这几个端口各开着什么服务??
为何我的80端口没开呢?

22 端口是开启SSH服务的。
打开httpd服务就会开80端口。
其它我不知道

我在浏览网页时不是80端口会开吗？
我怎不会开呢？？如果不打开httpd就一定不会开80，这样说对吗？

我也知道的一知半解。
0，不使用。
1-1023，系统保留。
1024-4999，由客户端使用。
5000-65535，服务器端口使用。
看一下/etc/services，可能明白点。
试一下。下面就是/etc/services的内容。

Note that it is presently the policy of IANA to assign a single well-known
port number for both TCP and UDP; hence, most entries here have two entries
even if the protocol doesn't support UDP operations.
Updated from RFC 1700, ``Assigned Numbers'' (October 1994). Not all ports
are included, only the more common ones.
The latest IANA port assignments can be gotten from
http://www.iana.org/assignments/port-numbers
The Well Known Ports are those from 0 through 1023.
The Registered Ports are those from 1024 through 49151
The Dynamic and/or Private Ports are those from 49152 through 65535
Each line describes one service, and is of the form:

unfortunately the poppassd (Eudora) uses a port which has already
been assigned to a different service. We list the poppassd as an
alias here. This should work for programs asking for this service.
