Using a PC as a proxy to access external networks from a server

1. Start a proxy on the PC, such as nginx

Download nginx: http://nginx.org/en/download.html

Modify the configuration file in the conf directory:

http {
    include       mime.types;
    default_type  application/octet-stream;
    
    sendfile        on;
    keepalive_timeout  65;

    server {
        listen       888;
        server_name  localhost;
        resolver 114.114.114.114;

        location / {          
           if ($scheme = 'http') {
               proxy_pass http://$host$request_uri;
            }
           if ($scheme = 'https') {
               proxy_pass https://$host$request_uri;
            }
            proxy_set_header Host $host;
            proxy_buffers 256 4k;
            proxy_max_temp_file_size 0k;
        }

    }
}

Start nginx by double-clicking.

Note: If using HTTPS, the Windows version cannot be used. A Linux version must be compiled manually. ./configure --prefix=/opt/nginx --with-http_ssl_module --add-module=./modules/ngx_http_proxy_connect_module --with-openssl=…/…/openssl/openssl-1.1.1 The HTTPS function currently works with curl https://blog.csdn.net/ but fails with curl https://baidu.com.

2. Start SSH

ssh -R localhost:xxx1:localhost:xxx2 username@serverIP

Parameters are: server port:PC host:PC port

After conencting, set the proxy:

export {http,https}_proxy='localhost:xxx1'

Note: This setting may still prompt "Unsupported proxy configured: localhost://7890" for apt commands. Add the following to apt.conf: Acquire::http::Proxy "http://127.0.0.1:7890"; Acquire::https::Proxy "http://127.0.0.1:7890";

The overall topology is now established.

Changing BIOS boot parameters via IPMI

First, turn off the power: ipmitool -H BMC_IP -U user -P password chassis power soft

Check if it's off: ipmitool -I lanplus -H BMC_IP -U user -P password power status

In one terminal, connect to the console: ipmitool -I lanplus -H BMC_IP -U user -P password sol activate

In another terminal, power on: ipmitool -I lanplus -H BMC_IP -U user -P password power on

Then press F4 (depending on the prompt) to enter BIOS.
