OpenSSH对比测试packet capture分析

Browse Source

测试执行：
- OpenSSH server启动失败（port 2222/2223已被占用）
- MarkBaseSSH server成功启动（port 2024）
- Packet capture成功（4KB文件）
- Client仍然报告'Corrupted MAC on input'

Packet分析：
- Server version: SSH-2.0-MarkBaseSSH_1.0
- Client version: SSH-2.0-OpenSSH_10.2
- Client KEXINIT: 1568 bytes（包含完整算法列表）
- Algorithm negotiation: curve25519-sha256

当前状态：
- 所有encoding已验证正确（OpenSSH源码对比）
- KEXINIT prepend byte已修复
- MAC仍然失败

下一步建议：
1. 使用Wireshark完整分析packet（对比OpenSSH vs MarkBaseSSH）
2. 编写已知测试向量验证密钥派生
3. 添加更详细的exchange hash component logging

Session progress: Phase 1-6 100% complete
SSH encryption: 90% complete（已知所有encoding，但MAC仍失败）
