Network Quality Check Script - 网络质量体检脚本 (CN)

Supported OS/Platform: Ubuntu | Debian | Linux Mint | Fedora | Red Hat Enterprise Linux (RHEL) | CentOS | Arch Linux | Manjaro | Alpine Linux | AlmaLinux | Rocky Linux | macOS | Anolis OS | Alibaba Cloud Linux | SUSE Linux | openSUSE | Void Linux

• Bilingual support: English & Chinese
• Supports IPv4/IPv6 dual-stack queries
• Well-formatted output for clear and concise display, optimized for screenshots
• Seven key modules: BGP information, local policy, access information, three-network TCP large packet latency, three-network return routing, domestic speed test, and international interconnection
• Base data sourced from BGP.TOOLS and BGP.HE.NET databases
• Intuitive display of upstream and access information
• Return latency tests for China Mainland’s 31 provinces/cities/autonomous regions via China Telecom, China Unicom, and China Mobile
• Speed test for China Mainland’s three major ISPs (including the Greater Bay Area) based on SPEEDTEST.NET
• Global speed and latency tests across five continents
• Flexible test modes: latency mode, low data mode, selective section skipping
• JSON output for big data analysis

Usage

Easy Mode: Run with Interactive Interface

bash <(curl -Ls Check.Place) -EN

Advanced Mode: Run with Parameters

Default dual-stack detection (Either):

bash <(curl -Ls Net.Check.Place) -E
bash <(curl -Ls Net.Check.Place) -l en

IPv4-only test:

bash <(curl -Ls Net.Check.Place) -E4

IPv6-only test:

bash <(curl -Ls Net.Check.Place) -E6

Latency mode:

bash <(curl -Ls Net.Check.Place) -EP

Low data mode:

bash <(curl -Ls Net.Check.Place) -EL

Full route mode (TCP result in Chinese):

bash <(curl -Ls Net.Check.Place) -E -R [Province]

Test Beijing & Shanghai & Guangdong by default:

bash <(curl -Ls Net.Check.Place) -E -R

Specify parameters to detect the corresponding province (Any of the following):

bash <(curl -Ls Net.Check.Place) -E -R 桂
bash <(curl -Ls Net.Check.Place) -E -R 广西
bash <(curl -Ls Net.Check.Place) -E -R 广西壮族自治区
bash <(curl -Ls Net.Check.Place) -E -R GX
bash <(curl -Ls Net.Check.Place) -E -R gx

Skip specific sections:

bash <(curl -Ls Net.Check.Place) -E -S 1234567

Bilingual support:

bash <(curl -Ls Net.Check.Place) -l cn|en

JSON output (Example Output):

bash <(curl -Ls Net.Check.Place) -Ej

Output report to file in ANSI/JSON/Text format:

bash <(curl -Ls Net.Check.Place) -o /path/to/file.ansi
bash <(curl -Ls Net.Check.Place) -o /path/to/file.json
bash <(curl -Ls Net.Check.Place) -o /path/to/file.txtoranyother

Skip checking OS and dependencies:

bash <(curl -Ls Net.Check.Place) -En

Auto-install dependencies:

bash <(curl -Ls Net.Check.Place) -Ey

Display full IP addresses in the report:

bash <(curl -Ls Net.Check.Place) -Ef
