Nintendo Switch 联网加速的一种姿势

最近 switch 上有了狂野飙车，但是在酒店的网络死活连不上。刚好朋友的 switch 想用舞力全开 unlimited 也不行，就天天试着各种方法。

开始就想着花钱用各种加速器，但是出差只带了公司的电脑，各种限制，电脑上开了各种加速器之后，根本没法共享给 switch。然后转战淘宝，发现有卖代理服务器的，就是给你个 IP+Port，先买个 1 块的试了试，下东西是很快，但是还是没法登陆狂野飙车，顺便看了下卖家给的服务器 IP 是美帝的。

然后想着能不能找个香港的服务器会好些，于是刚刚自己买了个阿里云国际的轻应用服务器，3.5$,搭建好之后，NAT 类型变成了 B，测速是 20Mbps 左右，几个朋友一起用，还是很合算的。

下面写下搭建过程，希望能帮得上有需要的人。如果有啥写错的，请轻喷~

#教程基于 CentOS

1.安装 Squid 并修改配置：

yum install squid -y
cp /etc/squid/squid.conf /etc/squid/squid.conf.bak
vi /etc/squid/squid.conf

我的配置文件，主要是修改端口和添加认证信息：

#
# Recommended minimum configuration:
#

# Example rule allowing access from your local networks.
# Adapt to list your (internal) IP networks from where browsing
# should be allowed
acl localnet src 10.0.0.0/8     # RFC1918 possible internal network
acl localnet src 172.16.0.0/12  # RFC1918 possible internal network
acl localnet src 192.168.0.0/16 # RFC1918 possible internal network
acl localnet src fc00::/7       # RFC 4193 local private network range
acl localnet src fe80::/10      # RFC 4291 link-local (directly plugged) machines

acl SSL_ports port 443
acl Safe_ports port 80          # http
acl Safe_ports port 21          # ftp
acl Safe_ports port 443         # https
acl Safe_ports port 70          # gopher
acl Safe_ports port 210         # wais
acl Safe_ports port 1025-65535  # unregistered ports
acl Safe_ports port 280         # http-mgmt
acl Safe_ports port 488         # gss-http
acl Safe_ports port 591         # filemaker
acl Safe_ports port 777         # multiling http
acl CONNECT method CONNECT

#
# Recommended minimum Access Permission configuration:
#
# Deny requests to certain unsafe ports
#http_access deny !Safe_ports

# Deny CONNECT to other than secure SSL ports
#http_access deny CONNECT !SSL_ports

# Only allow cachemgr access from localhost
http_access allow localhost manager
http_access deny manager

# We strongly recommend the following be uncommented to protect innocent
# web applications running on the proxy server who think the only
# one who can access services on "localhost" is a local user
#http_access deny to_localhost

#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#

# Example rule allowing access from your local networks.
# Adapt localnet in the ACL section to list your (internal) IP networks
# from where browsing should be allowed
#http_access allow localnet
http_access allow localhost

# And finally deny all other access to this proxy
#http_access deny all

# Squid normally listens to port 3128
#http_port 3128

# Uncomment and adjust the following to add a disk cache directory.
#cache_dir ufs /var/spool/squid 100 16 256

# Leave coredumps in the first cache dir
coredump_dir /var/spool/squid

#
# Add any of your own refresh_pattern entries above these.
#
refresh_pattern ^ftp:           1440    20%     10080
refresh_pattern ^gopher:        1440    0%      1440
refresh_pattern -i (/cgi-bin/|\?) 0     0%      0
refresh_pattern .               0       20%     4320
#用户认证文件的位置
auth_param basic program /usr/lib64/squid/basic_ncsa_auth /etc/squid/passwd
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated
#http 代理的端口，默认为 3128
http_port 12306
acl OverConnLimit maxconn 16       #定义每个 IP 最大允许 16 个连接，防止攻击

2.然后配置用户，为了安全：

先安装 httpd

yum install httpd* -y

添加用户：

htpasswd -c /etc/squid/passwd <username>
#然后输入密码。

重启 Squid 并启用开机启动：

systemctl restart squid
systemctl enable squid

3.测试:

先在 VPS 上本地测试下：

curl --proxy 127.0.0.1:PORT --proxy-user <username>:<password> http://www.baidu.com

如果有返回的话，应该就是 OK 了。

然后可以从其它 Linux 上测试下，记得在 VPS 管理的地方防火墙放通自己定义的 PORT：

curl --proxy <服务器 IP>:PORT --proxy-user <username>:<password> http://www.baidu.com

然后 Switch 只需要在连接 wifi 的地方配置好代理服务器 IP + PORT + User + Password,就能用了。

不保证每个地区都好用，具体的网络还是跟当地的情况有很大关系。阿里云这个机器带宽是 30M,我现在在杭州，网络是电信，测速有 20Mbps 左右，sShop 下载的时候，从服务器侧看，带宽跑到 17M 左右；朋友在重庆，测速只有 6Mbps，但是可以正常缓冲出舞力全开的在线歌曲。

Ps.也欢迎大家讨论其他更好用的方法。
