一、系统版本：
SuSe Enterprise Server Linux 9
二、具体操作过程和解释
1）备份/etc/xinetd.conf
Test:/ #cp /etc/xinetd.conf /etc/xinetd.conf.bak
Test:/ # id
uid=0(root) gid=0(root) groups=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel) context=root:system_r:unconfined_t
2）修改/etc/xinetd.conf文件中的instances参数（红色部分）
Test:/ # cat /etc/xinetd.conf
??#
??# xinetd.conf
??#

??
??defaults
??{
?? log_type = FILE /var/log/xinetd.log
?? log_on_success = HOST EXIT DURATION
?? log_on_failure = HOST ATTEMPT
??# only_from = localhost
?? instances = 30
?? cps = 50 10
??
??#
??# The specification of an interface is interesting, if we are on a firewall.
??# For example, if you only want to provide services from an internal
??# network interface, you may specify your internal interfaces IP-Address.
??#
??# interface = 127.0.0.1
??
??}
??
??includedir /etc/xinetd.d
??
修改instances参数为实际需要值即可。
