未注释的行C:\ProgramData\ssh\sshd_config
Port 22

Subsystem sftp sftp-server.exe
在 Windows 服务器上,公钥存在于C:\Users\john.doe\.ssh\authorized_keys
我只是不确定配置出了什么问题。有什么想法吗?
答案1
也许是文件权限问题。
在文件 contrib/win32/win32compat/w32-sshfileperm.c 中,有这样一条注释:
/*
* The function is to check if current user is secure to access to the file.
* Check the owner of the file is one of these types: Local Administrators groups, system account, current user account
* Check the users have access permission to the file don't voilate the following rules:
* 1. no user other than local administrators group, system account, and pwd user have write permission on the file
* 2. sshd account can only have read permission
* Returns 0 on success and -1 on failure
*/
int
check_secure_file_permission(const char *input_path, struct passwd * pw)
您需要检查权限是否正确:
- 在用户
home
目录(C:\Users\john.doe) - 在
.ssh
目录 (C:\Users\john.doe\.ssh)上 - 并在
authorized_keys
文件(C:\Users\john.doe\.ssh\authorized_keys)上。
