xinetd.conf可以说是预设值的设定档。假设这边启动了rsync服务，但是在rsync此服务并没有特别去设定参数，因此在设定值部份就会以xinetd.conf为主。

以下是预设定xinetd.conf
[root@localhost ~]# vim /etc/xinetd.conf
defaults
{

The next two items are intended to be a quick access place to

temporarily enable or disable services.

enabled = #启用

disabled = #禁用

Define general logging characteristics.

log_type = SYSLOG daemon info #登录档的记录服务类型
log_on_failure = HOST #发生错误时需要记录的资讯为主机 (HOST)
log_on_success = PID HOST DURATION EXIT #成功启动或登入时的记录资讯

Define access restriction defaults

no_access =

only_from =

max_load = 0

cps = 50 10 #同一秒内最大连线数为 50 个，超过则暂停 10 秒
instances = 50 #同一服务的最大同时连线数
per_source = 10 # 同一来源的用户端的最大连线数

Address and networking defaults

bind =

mdns = yes

v6only = no #是否仅允许 IPv6

setup environmental attributes

passenv =

groups = yes
umask = 002

Generally, banners are not used. This sets up their global defaults

banner =

banner_fail =

banner_success =

}
includedir /etc/xinetd.d #在/etc/xinetd.d会有更多的设定值
