一.查看环境

[root@JSCS78DB dev]# cat /etc/redhat-release

二.关闭防火墙

checkconfig --list
[root@JSCS78DB home]# export LANG=C
[root@JSCS78DB home]# chkconfig --list | grep iptables
iptables        0:off   1:off   2:on    3:on    4:on    5:on    6:off
[root@JSCS78DB home]#

[root@JSCS78DB home]# service iptables status
表格：filter
