|
||
|
||

md5 /tmp/scp_test/test_50mb.bin
|
||
```
|
||
|
||

|
||
- ✅ 传输速率: 33 MB/s
|
||

|
||
## 测试 3: 100MB 文件传输 ⭐⭐⭐⭐⭐
|
||
|
||
**命令**：
|
||
```bash
|
||
dd if=/dev/urandom of=/tmp/test_100mb.bin bs=1M count=100
|
||
scp -O /tmp/test_100mb.bin demo@127.0.0.1:/tmp/scp_test/
|
||
md5 /tmp/test_100mb.bin
|
||
md5 /tmp/scp_test/test_100mb.bin
|
||
```
|
||
|
||
**结果**：
|
||
- ✅ 传输时间: 4s
|
||
- ✅ 传输速率: 25 MB/s
|
||
- ✅ MD5 校验一致
|
||
- ✅ 文件完整性验证成功
|
||
- ✅ **SCP legacy protocol 成功验证**

||
## SCP over SFTP subsystem 测试 ❌
|
||
|
||
**命令**：
|
||
```bash
|
||
# 不使用 -O 参数（默认使用 SFTP subsystem）
|
||
scp /tmp/test_10mb.bin demo@127.0.0.1:/tmp/scp_sftp_test/
|
||
```
|
||
|
||
**结果**：
|
||
- ❌ 传输失败（SFTP subsystem 未实现 SCP support）
|
||
- ⏳ 待 Phase 17 实现
|
||

|
||
|
||
## SCP 命令检测验证 ⭐⭐⭐⭐⭐
|
||
|
||
**SSH server 日志关键记录**：
|
||
```
|
||
[EXEC_REQUEST] Detected SCP command: scp -t /tmp/scp_test/
|
||
[INTERACTIVE_EXEC] scp process started: scp -t /tmp/scp_test/
|
||
[PROCESS_STDOUT] scp output: C0644 104857600 test_100mb.bin
|
||
[PROCESS_STDOUT] scp output: <binary data 32768 bytes>
|
||
[WINDOW_DECREASED] channel 0 local_window decreased by 32768 bytes
|
||
[WINDOW_ADJUST] channel 0 needs adjust
|
||
```
|
||
|
||
**验证结果**：
|
||
- ✅ SCP 命令正确识别（scp -t/-f）
|
||
- ✅ handle_interactive_exec() 正确启动进程
|
||
- ✅ Window Control 正确工作（与 rsync 共用逻辑）
|
||
- ✅ 文件完整性验证成功
|
||
|

|
||
|
||
## SCP vs rsync 性能对比
|
||
|
||
| 协议 | 文件大小 | 传输时间 | 传输速率 | Window Control |
|
||
|------|---------|---------|---------|---------------|
|
||
| **SCP legacy** | 10MB | 0.3s | 30 MB/s | ✅ 成功 |
|
||
| **SCP legacy** | 50MB | 1.5s | 33 MB/s | ✅ 成功 |
|
||
| **SCP legacy** | 100MB | 4s | 25 MB/s | ✅ 成功 |
|
||
| **rsync** | 10MB | 0.4s | 24 MB/s | ✅ 成功 |
|
||
| **rsync** | 50MB | 1.4s | 36 MB/s | ✅ 成功 |
|
||
| **rsync** | 100MB | 4s | 21 MB/s | ✅ 成功 |
|
||
|
||
**结论**：
|
||
- SCP legacy protocol 性能略优于 rsync
|
||
- Window Control 在两种协议下都工作正常
|
||
- SCP over SFTP subsystem 待实现

## handle_scp_exec() 实现验证
|
||
|
||
**代码路径**：`markbase-core/src/ssh_server/channel.rs:350-420`
|
||
|
||
**关键逻辑**：
|
||
```rust
|
||
if command.starts_with("scp") || command.contains("scp -") {
|
||
info!("[EXEC_REQUEST] Detected SCP command: {}", command);
|
||
self.handle_scp_exec(&command, channel)?;
|
||
}
|
||
|
||
fn handle_scp_exec(&mut self, command: &str, channel_id: u32) -> Result<()> {
|
||
// SCP和rsync共用相同的交互式exec逻辑
|
||
self.handle_interactive_exec(command, channel_id, "scp")
|
||
}
|
||
```
|
||
|
||
**验证结果**：
|
||
- ✅ SCP 命令正确识别
|
||
- ✅ handle_interactive_exec() 正确启动进程
|
||
- ✅ Window Control 正确工作
|
||
- ✅ 文件传输成功
|
||

|
||
|
||
## 总结
|
||
|
||
**测试结果**：SCP legacy protocol 全部通过 ⭐⭐⭐⭐⭐
|
||
|
||
**关键验证**：
|
||
1. ✅ SCP 命令检测（scp -t/-f）
|
||
2. ✅ handle_interactive_exec() 实现正确
|
||
3. ✅ Window Control 与 SCP 共用逻辑
|
||
4. ✅ 10MB-100MB 传输全部成功
|
||
5. ✅ 文件完整性验证成功
|
||
|
||
**待实现**：
|
||
- ❌ SCP over SFTP subsystem（Phase 17）
