#注意：这一部分的内容需要根据你自己的实验环境来设置

#1.客户端 IP 列表：选择20个，且不能在局域网中存在
# 示例
# IPS=(
#    "192.168.1.200"
#    "192.168.1.201"
# )

IPS=(
    "192.168.1.200"
    "192.168.1.201"
)

#2.客户端 IP 对应的子网掩码
#示例：
#NETMASK="255.255.248.0"
NETMASK="255.255.248.0"

#3.服务端的 IP 和 端口
#示例
#SERVERIP="192.168.1.100"
#SERVERPORT="8090"
SERVERIP="192.168.1.100"
SERVERPORT="8090"
