rustdesk-doctor

rustdesk-doctor is a diagnostic tool that systematically identifies why RustDesk remote desktop connections fail. Use it when users report connection problems, missing IDs, registration failures, or inability to establish remote sessions. The tool performs parallel checks of client status, Clash proxy interference, server configuration, and cloud security settings, then delivers comprehensive troubleshooting findings.

# RustDesk 连接诊断工具

诊断 RustDesk 客户端无法连接服务器的问题,覆盖 Clash/TUN 代理干扰、服务器端配置、云安全组等常见根因。

用户传入的参数(如有):$ARGUMENTS

## 诊断流程

严格按以下步骤执行,每一步都要执行并记录结果,最后给出综合诊断。

### 第一步:采集客户端状态

**并行执行以下检查:**

1. **RustDesk 进程和网络连接**
```bash
ps aux | grep -i rustdesk | grep -v grep
echo "=== 网络连接 ==="
lsof -i -P -n 2>/dev/null | grep -i rustdesk
```

2. **RustDesk 配置文件**
```bash
CONFIG_DIR="$HOME/Library/Preferences/com.carriez.RustDesk"
echo "=== RustDesk2.toml ==="
cat "$CONFIG_DIR/RustDesk2.toml" 2>/dev/null || echo "文件不存在"
echo "=== RustDesk_local.toml ==="
cat "$CONFIG_DIR/RustDesk_local.toml" 2>/dev/null || echo "文件不存在"
```

3. **RustDesk 最新日志(关键行)**
```bash
LOG="$HOME/Library/Logs/RustDesk/RustDesk_rCURRENT.log"
cat "$LOG" 2>/dev/null || echo "日志不存在"
```

### 第二步:检查 Clash/代理干扰

**并行执行以下检查:**

1. **Mihomo 中 RustDesk 的连接和规则匹配**
```bash
SOCKET="/var/tmp/verge/verge-mihomo.sock"
if [ -S "$SOCKET" ]; then
  curl -s --unix-socket "$SOCKET" http://localhost/connections 2>/dev/null | python3 -c "
import sys,json
data=json.load(sys.stdin)
conns=data.get('connections',[])
found=False
for c in conns:
    meta=c.get('metadata',{})
    proc=meta.get('process','').lower()
    host=meta.get('host','').lower()
    dst=meta.get('destinationIP','')
    if 'rustdesk' in proc or 'rustdesk' in host or '21116' in meta.get('destinationPort','') or '21115' in meta.get('destinationPort',''):
        chains=c.get('chains',[])
        rule=c.get('rule','')
        rp=c.get('rulePayload','')
        net=meta.get('network','')
        dp=meta.get('destinationPort','')
        print(f'{meta.get(\"process\",\"\")} | {net} | {host or dst}:{dp} | rule={rule} {rp} | chains={chains}')
        found=True
if not found:
    print('Mihomo 中没有 RustDesk 相关连接')
"
else
  echo "Mihomo unix socket 不存在,Clash 可能未运行"
fi
```

2. **Mihomo 中 RustDesk 相关规则**
```bash
SOCKET="/var/tmp/verge/verge-mihomo.sock"
if [ -S "$SOCKET" ]; then
  curl -s --unix-socket "$SOCKET" http://localhost/rules 2>/dev/null | python3 -c "
import sys,json
rules=json.load(sys.stdin).get('rules',[])
for r in rules:
    p=str(r.get('payload','')).lower()
    if 'rustdesk' in p:
        print(f\"{r.get('type')},{r.get('payload')},{r.get('proxy')}\")
" || echo "无法获取规则"
  echo "=== TUN 配置 ==="
  curl -s --unix-socket "$SOCKET" http://localhost/configs 2>/dev/null | python3 -c "
import sys,json
c=json.load(sys.stdin)
tun=c.get('tun',{})
print('TUN enabled:', tun.get('enable'))
rea=tun.get('route-exclude-address',[])
if rea:
    print('route-exclude-address:', rea)
"
fi
```

3. **DNS 解析检查(fake-ip 检测)**

对 RustDesk 服务器域名进行 DNS 解析,检查是否返回 fake-ip (198.18.x.x):
```bash
# 如果配置了自建服务器(IP 地址),跳过域名解析
# 如果使用默认公共服务器,检查 rs-ny.rustdesk.com
nslookup rs-ny.rustdesk.com 2>&1
nslookup rustdesk.com 2>&1
```

4. **路由检查**

检查 RustDesk 服务器 IP 的路由走向(是否经过 TUN utun1024):
```bash
# 对配置中的服务器 IP 执行 route get
# 如果走 utun1024 → TUN 拦截
# 如果走 en0 → 直连
route -n get <服务器IP> 2>&1 | head -6
```

5. **Clash Verge profiles 中的 RustDesk 配置**
```bash
PROFILES_DIR="$HOME/Library/Application Support/io.github.clash-verge-rev.clash-verge-rev/profiles"
grep -ril "rustdesk" "$PROFILES_DIR/"*.yaml "$PROFILES_DIR/"*.js 2>/dev/null | while read f; do
  echo "=== $(basename $f) ==="
  grep -in "rustdesk" "$f"
done
```

### 第三步:网络连通性测试

**对配置中的服务器(自建或默认公共服务器)执行:**

```bash
SERVER="<服务器IP或域名>"
echo "=== TCP 21115 (NAT test) ==="
nc -z -w5 $SERVER 21115 2>&1 && echo "OK" || echo "FAIL"
echo "=== TCP 21116 (rendezvous) ==="
nc -z -w5 $SERVER 21116 2>&1 && echo "OK" || echo "FAIL"
echo "=== TCP 21117 (relay) ==="
nc -z -w5 $SERVER 21117 2>&1 && echo "OK" || echo "FAIL"
echo "=== UDP 21116 ==="
nc -z -w5 -u $SERVER 21116 2>&1 && echo "OK" || echo "FAIL(UDP 结果可能不准确)"
echo "=== 路由走向 ==="
route -n get $SERVER 2>&1 | head -6
```

### 第四步:服务器端检查(如可 SSH)

如果用户提供了自建服务器 IP 且可以 SSH,执行以下检查:

```bash
SERVER="<服务器IP>"
ssh -o ConnectTimeout=10 root@$SERVER "
echo '=== Docker 容器状态 ==='
docker ps | grep -i rust
echo '=== hbbs 日志(最后 20 行)==='
docker logs hbbs --tail 20 2>&1
echo '=== hbbr 日志(最后 10 行)==='
docker logs hbbr --tail 10 2>&1
echo '=== 端口监听 ==='
ss -ulnp | grep 21116
ss -tlnp | grep -E '2111[5-9]'
echo '=== 公钥 ==='
cat /root/id_ed25519.pub 2>/dev/null || find / -name 'id_ed25519.pub' 2>/dev/null | head -1 | xargs cat 2>/dev/null
echo '=== UFW 状态 ==='
ufw status 2>/dev/null | head -15
echo '=== 云安全组防火墙链 ==='
iptables -L INPUT -n 2>/dev/null | head -5
echo '=== 抓包测试(10秒)==='
timeout 10 tcpdump -i eth0 -c 5 udp port 21116 2>&1
"
```

### 第五步:local-ip-addr 检查

检查 RustDesk 是否把 TUN 网关 IP 当成了本机 IP:

```bash
CONFIG="$HOME/Library/Preferences/com.carriez.RustDesk/RustDesk2.toml"
LOCAL_IP=$(grep 'local-ip-addr' "$CONFIG" 2>/dev/null | awk -F"'" '{print $2}')
if [ "$LOCAL_IP" = "198.18.0.1" ]; then
  echo "WARNING: local-ip-addr = 198.18.0.1 (TUN 网关假 IP)"
  echo "RustDesk 启动时检测到 TUN 虚拟网卡 IP,需要在 TUN 关闭时启动 RustDesk"
  REAL_IP=$(ifconfig en0 2>/dev/null | grep 'inet ' | awk '{print $2}')
  echo "真实 IP 应该是: $REAL_IP"
elif [ -n "$LOCAL_IP" ]; then
  echo "local-ip-addr = $LOCAL_IP"
else
  echo "local-ip-addr 未设置(自动检测)"
fi
```

## 综合诊断

根据采集到的所有信息,按以下判断矩阵分析:

### 常见问题判断矩阵

| 日志关键行 | 网络状态 | Clash 状态 | 诊断 |
|-----------|---------|-----------|------|
| `register_pk ... key not confirmed` 持续重试 | 端口不通 | 走 DIRECT | **TUN DIRECT UDP 转发异常或服务器不可达** |
| `register_pk ... key not confirmed` 持续重试 | 端口通 | 走 Proxies | **代理节点不支持 RustDesk UDP 协议** |
| `register_pk ... key not confirmed` + 服务器 tcpdump 零包 | SSH 通,其他端口不通 | - | **云安全组未放行 21115-21117/tcp 和 21116/udp** |
| `Got nat response` 有回复但 `register_pk` 失败 | UDP 通,TCP 21115 不通 | 走 Proxies | **代理对裸 TCP 转发不完整,需加 IP-CIDR 规则** |
| `Failed to connect to ...:21115` | TCP 不通 | - | **TCP 21115 被阻断(代理/防火墙/安全组)** |
| `local-ip-addr = 198.18.0.1` | - | TUN 开启 | **TUN 假 IP 污染,关 TUN 重启 RustDesk 或清空该字段** |
| `error sending request for url (https://api.rustdesk.com/...)` | HTTPS 不通 | 走 DIRECT | **RustDesk 官方 API 被墙,需走代理** |
| DNS 解析返回 198.18.x.x | - | fake-ip 模式 | **rustdesk.com 需加入 fake-ip-filter 或改用 +.rustdesk.com** |
