============================================

Komari Agent 安装问题 - 纯 IPv6 环境连接失败

============================================

1. 系统环境

#被控系统 Debian 11
#主控系统 Debian 12

被控端：纯 IPv6 环境

主控端：仅 IPv4，通过 Cloudflare Tunnel 暴露服务

2. 安装命令（使用 HTTP）

wget -qO- https://raw.githubusercontent.com/komari-monitor/komari-agent/refs/heads/main/install.sh | sudo bash -s -- -e http://w.fwq.jx.fyi -t xxxxx --disable-auto-update --memory-include-cache

3. 安装输出

4. 查看服务状态（无后续日志输出）

sudo journalctl -u komari-agent -n 50 --no-pager

-- Journal begins at Sat 2026-05-09 23:58:58 CST, ends at Sun 2026-05-10 00:02:29 CST. --

注意：启动后没有任何网络请求日志（没有 "Uploading basic info" 或 "Connecting to WebSocket"）

5. 手动运行 Agent（前台模式）

sudo systemctl stop komari-agent
sudo /opt/komari/agent -e http://w.fwq.jx.fyi -t xxxxx --disable-auto-update --memory-include-cache

2026/05/10 00:04:57 Komari Agent 1.2.0
2026/05/10 00:04:57 Github Repo: komari-monitor/komari-agent
2026/05/10 00:04:57 Using system default DNS resolver
2026/05/10 00:04:57 Monitoring Mountpoints: [/ (zfs)]
2026/05/10 00:04:57 Monitoring Interfaces: [sit0 eth0 eth1]

手动运行同样没有网络请求，卡在初始化阶段

6. 测试 HTTP 连接（成功）

curl -v http://w.fwq.jx.fyi/api/version

• Trying 2606:4700:3035::ac43:b91f:80...
• Connected to w.fwq.jx.fyi (2606:4700:3035::ac43:b91f) port 80 (#0)

GET /api/version HTTP/1.1
Host: w.fwq.jx.fyi
User-Agent: curl/7.74.0
Accept: /

• Mark bundle as not supporting multiuse
  < HTTP/1.1 200 OK
  < Date: Sat, 09 May 2026 16:03:50 GMT
  < Content-Type: application/json; charset=utf-8
  < Content-Length: 110
  < Connection: keep-alive
  < Cache-Control: no-store
  < cf-cache-status: DYNAMIC
  < Server: cloudflare
  <
  {"status":"success","message":"","data":{"hash":"567d2b66fb5d05545abd89a2843f1c7c94e8fff4","version":"1.2.0"}}

HTTP 连接正常，API 响应成功

7. 测试 HTTPS 连接（失败 - TLS 握手失败）

curl -v https://w.fwq.jx.fyi/api/version

• Trying 2606:4700:3031::6815:4883:443...
• Connected to w.fwq.jx.fyi (2606:4700:3031::6815:4883) port 443 (#0)
• ALPN, offering h2
• ALPN, offering http/1.1
• successfully set certificate verify locations:
• CAfile: /etc/ssl/certs/ca-certificates.crt
• CApath: /etc/ssl/certs
• TLSv1.3 (OUT), TLS handshake, Client hello (1):
• TLSv1.3 (IN), TLS alert, handshake failure (552):
• error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure
• Closing connection 0
  curl: (35) error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure

HTTPS 连接失败，TLS 握手失败

8. 查看 Agent 进程参数

ps aux | grep agent

root 2810 0.0 1.7 1231412 4404 ? Ssl 00:01 0:00 /opt/komari/agent -e http://w.fwq.jx.fyi -t xxxxx --disable-auto-update --memory-include-cache

9. 查看服务文件

cat /etc/systemd/system/komari-agent.service

[Unit]
Description=Komari Agent Service
After=network.target

[Service]
Type=simple
ExecStart=/opt/komari/agent -e http://w.fwq.jx.fyi -t xxxxx --disable-auto-update --memory-include-cache
WorkingDirectory=/opt/komari
Restart=always
User=root

[Install]
WantedBy=multi-user.target

10. DNS 解析结果

getent ahosts w.fwq.jx.fyi

2606:4700:3035::ac43:b91f STREAM w.fwq.jx.fyi
2606:4700:3035::ac43:b91f DGRAM

============================================

问题总结

============================================

1. Agent 安装成功，服务启动正常

2. Agent 启动后没有网络请求日志，卡在初始化阶段

3. HTTP 手动测试成功（主控 API 正常响应）

4. HTTPS 手动测试失败（TLS 握手失败）

5. 其他有 IPv4 和IPv6 的被控服务器使用相同配置（HTTPS + 主域名）正常工作

6. 问题仅出现在纯 IPv6 环境 + Cloudflare 代理的场景（有些机器就可以正常上报有些接不可以）
