Redhat 5 使用 Samba 3.6 在 Windows 7 上导致系统错误 58

我目前正在尝试让 Redhat 5 上运行的旧独立 Samba Share 服务器恢复运行！它之前运行的是 3.0 版本，由于存在很多问题，我决定使用官方软件包升级到 3.6 版本。现在，我在 Radhat 5 上正确运行了 samba 3.6

Red Hat Enterprise Linux Server release 5.11 (Tikanga)

Samba version 3.6.23-12.el5_11

这是我的 testparm 输出：

我能够从本地主机连接到其中一个共享：

>$ smbclient //DUMMYMO/diro -U usero usero
Domain=[DUMMY] OS=[Unix] Server=[Samba 3.6.23-12.el5_11]
smb: \>

这很好，但我仍然想知道为什么它不能在 Windows 7 机器上运行：

>$ net use x: \\DUMMYMO\diro /user:usero usero
System error 58 has occurred.

The specified server cannot perform the requested operation.

通过将日志级别设置为 3，我能够在 Windows 连接尝试期间看到这些日志行：

这是网络跟踪：

正如日志中提到的，客户端在服务器应答后直接发送了一个 RST 标志，我不知道为什么。我已经尝试了许多解决方案，例如最小协议、服务器签名，但都没有成功。

我没有其他解决办法。您有什么建议吗？

请注意，我没有桌面的管理员访问权限，并且我猜测许多参数都是由域强加的。

答案1

感谢 MadHatter 的提示，我得以解决这个问题：客户端只需要 SMB2，而不是 SMB3。此技巧可轻松应用于 Global 部分下的配置中：

最大协议 = SMB2
