BSD单用户级与多用户级启动脚本/etc/rc.d/rc.1
脚本执行后,除了内核后台程序和init外都将关闭。登陆程序将开启,su:S1:reSPAwn:/sbin/sulogin指定的功能。只有root用户才能用系统。

# 这个例子里网卡ip设置为192.168.0.2 。子网掩码为255.255.255.0,网关为192.168.0.1
### You may wish to add some commands changing sysctl states here, for example:
# echo 1 > /proc/sys/net/ipv4/ip_forward # enable IP forwarding
# echo 1 > /proc/sys/net/ipv4/tcp_syncookies # defend against SYN flood
#设置网卡

### you can create additional scripts for specific (networking) tasks,
### for example NFS, which needs a lot of daemons to work (see 3.2)
### or your firewall script:
# 有防火墙则去下面注释
# if [ -x /etc/rc.d/rc.firewall ]; then
# echo "Restoring firewall rules..."
# /etc/rc.d/rc.firewall
# fi
# 网络的一些后台程序,如NFS
# if [ -x /etc/rc.d/rc.netdaemons ]; then
# echo "Starting network daemons..."
# /etc/rc.d/rc.netdaemons
# fi
# 用户个人配制文件
if [ -x /etc/rc.d/rc.local ]; then
/etc/rc.d/rc.local
fi
