连上 pangolin 后一键测:出口IP确认 / 客户端→节点真实路径(绑en0绕隧道, RTT+丢包) / 经隧道TTFB / Cloudflare 下行+上行带宽;--node 可 ssh 节点测 其自身出口带宽做理论上限对照。零依赖(curl+ping)。 实测节点(RackNerd 512MB/1核,LA):下行~22-24 / 上行~25 Mbps,RTT 298ms, 0% 丢包(晚高峰偶发瞬时丢包)。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

# speedtest.sh — pangolin 隧道速度/质量验证工具
|
|
#
|
|
# 在【pangolin 已连接】状态下运行(全局隧道,本机流量经节点出网),测:
|
|
# 1. 出口确认 — 出口 IP 是否=节点(确认走的是 pangolin 而非别的代理)
|
|
# 2. 链路质量 — 绑 en0 直测客户端→节点真实路径 RTT/丢包(绕开隧道)
|
|
# 3. 代理延迟 — 经隧道访问几个站点的首字节时间(TTFB)
|
|
# 4. 下行带宽 — 经隧道从 Cloudflare 下载,算 Mbps
|
|
# 5. 上行带宽 — 经隧道上传到 Cloudflare,算 Mbps
|
|
#
|
|
# 用法:
|
|
# bash scripts/speedtest.sh # 默认下/上行各 50MB / 10MB
|
|
# bash scripts/speedtest.sh --node # 额外 ssh 节点测其自身出口带宽(理论上限对照)
|
|
# DL_MB=100 UL_MB=20 bash scripts/speedtest.sh
|
|
#
|
|
# 环境变量:
|
|
# NODE_IP 节点公网 IP(默认 107.172.55.251)
|
|
# NODE_SSH 节点 ssh 别名(默认 racknerd,仅 --node 用)
|
|
# DL_MB 下行测试大小 MB(默认 50)
|
|
# UL_MB 上行测试大小 MB(默认 10)
