Apache Mina SSHD - FileZilla 显示错误的目录结构
Apache Mina SSHD - FileZilla shows wrong directory structure
我使用 Apache Mina SSHD 将 SSH 服务器设置为 SFTP 服务器。我实现了自己的 FileSystemFactory，以便为登录的用户创建特定目录。当我使用 FileZilla 打开与服务器的连接时，目录结构显示错误。
在根目录视图中，显示一个空文件夹。这个不存在。应该只有两个目录。 "Upload" 和 "Download".
当我打开上传目录时，我再次看到一个空目录，不应该显示，因为它不存在。此外，还显示了另一个上传目录。我无法打开它，因为它说 /upload/upload 不存在，这是真的，但我不明白为什么会显示它。
当我连接 WinSCP 时，我没有得到这个显示错误。有谁知道为什么会这样或者怎么解决？
编辑：
FileSystemFactory 实施：
public class CustomFileSystemFactory implements FileSystemFactory {
private String defaultHomeDir;
private FileSystem fileSystem;
public CustomFileSystemFactory(String defaultHomeDir){
this.defaultHomeDir = defaultHomeDir;
}
public String getDefaultHome(){
return defaultHomeDir;
}
public FileSystem getFileSystem(){
return fileSystem;
}
@Override
public FileSystem createFileSystem(Session session) throws IOException {
Path dir = computeRootDir(session.getUsername());
if (dir == null) {
throw new InvalidPathException(session.getUsername(), "Cannot resolve home directory");
}
if(!Files.exists(dir)){
Files.createDirectory(dir);
}
setupFolders(session.getUsername());
FileSystem fileSystem = new RootedFileSystemProvider().newFileSystem(dir, Collections.emptyMap());
return fileSystem;
}
protected Path computeRootDir(String username){
Path path = Paths.get(defaultHomeDir + Utils.getPrincipalExtId(username) + "/");
return path;
}
protected void setupFolders(String username) throws IOException {
Path homeDir = computeRootDir(username);
File uploadFolder = new File(homeDir + "/upload/");
File downloadFolder = new File(homeDir + "/download/");
if(!uploadFolder.exists()){
uploadFolder.mkdirs();
}
if(!downloadFolder.exists()){
downloadFolder.mkdirs();
}
}
}

问候
问题已在 Apache Mina SSHD 1.1.0 中解决，参见
- https://issues.apache.org/jira/browse/SSHD-622
- https://gitbox.apache.org/repos/asf?p=mina-sshd.git;a=commit;h=2bd4f5709b433495d040249dcb83e5025b6c9227
保留早期版本的解决方案：
Mina SSHD 服务器和 FileZilla 客户端都有部分问题。
在 SFTP 版本 3（FileZilla 使用）中，每个文件的条目都包含结构化元数据和 display-only 字符串（又名 longname 字段），其格式与*nix ls -l 命令。 display-only 字符串不应被解析。
但 FileZilla 会解析它，而不是使用结构化元数据（文件时间戳除外）。 FileZilla 用于实施 SFTP 协议的内部 psftp 进程仅向父 FileZilla 进程（sftp_cmd_ls 函数）提供此信息：
if (ournames[i]->attrs.flags & SSH_FILEXFER_ATTR_ACMODTIME) {
mtime = ournames[i]->attrs.mtime;
}
fzprintf(sftpListentry, "%lu %s", mtime, ournames[i]->longname);
米娜SSHD/SFTP（SftpSubsystemclass），在列出.和..meta-directories时，错误地使用了电流display-only 字符串中的文件夹名称和父文件夹名称，而不是 . 和 ..。它在结构化元数据（shortname 字段）中正确使用 . 和 ..。
FileZilla 从列表中读取了错误的名称并感到困惑，将条目视为实际的子目录条目，而不是 meta-directories。
在根目录中，.和..可能都列为/。 FileZilla 修剪所有内容，直到最后一个 /，导致空条目（并且两个 same-named [empty-named] 条目可能合并为一个）。
所以不用
.
..
upload
download
FileZilla 看到
/ [treated as an empty string]
/ [treated as an empty string and ignored as duplicate]
upload
download
在 upload 目录中，. 被列为 upload，.. 被列为 /（导致空条目）。
所以不用
.
..
FileZilla 看到
upload
/ [treated as an empty string]
WinSCP 相反，从不使用 display-only 字符串来解析 file/directory 名称。并且主要（如果服务器支持，Mina SSHD 所做的）使用 SFTP 版本 4，它甚至不包括 display-only 字符串。
要解决此问题，您需要将 SftpSubsystem.writeDirEntry 方法的 shortName 参数传递给被调用的 .getLongName 方法。并修改 .getLongName 以在字符串中使用 shortName returns 而不是 getShortName(f).
请参阅下面的 SftpSubsystem 修改代码，其中包含描述更改的注释。代码来自Mina SSHD version 1.0
protected void writeDirEntry(int id, DirectoryHandle dir, Buffer buffer, int index, Path f, String shortName, LinkOption... options) throws IOException {
...
if (version == SFTP_V3) {
// added shortName argument
String longName = getLongName(f, options, shortName);
} else {
...
}
// added shortName parameter
protected String getLongName(Path f, LinkOption... options, String shortName) throws IOException {
// added shortName argument
return getLongName(f, true, options, shortName);
}
// added shortName parameter
private String getLongName(Path f, boolean sendAttrs, LinkOption... options, String shortName) throws IOException {
...
// added shortName argument
return getLongName(f, attributes, shortName);
}
// added shortName parameter
private String getLongName(Path f, Map<String, ?> attributes, String shortName) throws IOException {
...
return (SftpHelper.getBool(isDirectory) ? "d" : (SftpHelper.getBool(isLink) ? "l" : "-"))
+ PosixFilePermissions.toString(perms) + " "
+ (attributes.containsKey("nlink") ? attributes.get("nlink") : "1")
+ " " + username + " " + group + " " + lengthString + " "
+ UnixDateFormat.getUnixDate((FileTime) attributes.get("lastModifiedTime"))
// using shortName instead of getShortName(f)
+ " " + shortName;
}
// + you need to modify sendPath to pass getShortName(f)
// to its call to getLongName
我不会Java，所以请原谅任何错误的代码。
考虑将错误报告给 Mina SSHD 项目。 Link这里的问题，如果你这样做。
我使用 Apache Mina SSHD 将 SSH 服务器设置为 SFTP 服务器。我实现了自己的 FileSystemFactory，以便为登录的用户创建特定目录。当我使用 FileZilla 打开与服务器的连接时，目录结构显示错误。
在根目录视图中，显示一个空文件夹。这个不存在。应该只有两个目录。 "Upload" 和 "Download".
当我打开上传目录时，我再次看到一个空目录，不应该显示，因为它不存在。此外，还显示了另一个上传目录。我无法打开它，因为它说 /upload/upload 不存在，这是真的，但我不明白为什么会显示它。
当我连接 WinSCP 时，我没有得到这个显示错误。有谁知道为什么会这样或者怎么解决？
编辑：
FileSystemFactory 实施：
public class CustomFileSystemFactory implements FileSystemFactory {
private String defaultHomeDir;
private FileSystem fileSystem;
public CustomFileSystemFactory(String defaultHomeDir){
this.defaultHomeDir = defaultHomeDir;
}
public String getDefaultHome(){
return defaultHomeDir;
}
public FileSystem getFileSystem(){
return fileSystem;
}
@Override
public FileSystem createFileSystem(Session session) throws IOException {
Path dir = computeRootDir(session.getUsername());
if (dir == null) {
throw new InvalidPathException(session.getUsername(), "Cannot resolve home directory");
}
if(!Files.exists(dir)){
Files.createDirectory(dir);
}
setupFolders(session.getUsername());
FileSystem fileSystem = new RootedFileSystemProvider().newFileSystem(dir, Collections.emptyMap());
return fileSystem;
}
protected Path computeRootDir(String username){
Path path = Paths.get(defaultHomeDir + Utils.getPrincipalExtId(username) + "/");
return path;
}
protected void setupFolders(String username) throws IOException {
Path homeDir = computeRootDir(username);
File uploadFolder = new File(homeDir + "/upload/");
File downloadFolder = new File(homeDir + "/download/");
if(!uploadFolder.exists()){
uploadFolder.mkdirs();
}
if(!downloadFolder.exists()){
downloadFolder.mkdirs();
}
}
}

问候
问题已在 Apache Mina SSHD 1.1.0 中解决，参见
- https://issues.apache.org/jira/browse/SSHD-622
- https://gitbox.apache.org/repos/asf?p=mina-sshd.git;a=commit;h=2bd4f5709b433495d040249dcb83e5025b6c9227
保留早期版本的解决方案：
Mina SSHD 服务器和 FileZilla 客户端都有部分问题。
在 SFTP 版本 3（FileZilla 使用）中，每个文件的条目都包含结构化元数据和 display-only 字符串（又名 longname 字段），其格式与*nix ls -l 命令。 display-only 字符串不应被解析。
但 FileZilla 会解析它，而不是使用结构化元数据（文件时间戳除外）。 FileZilla 用于实施 SFTP 协议的内部 psftp 进程仅向父 FileZilla 进程（sftp_cmd_ls 函数）提供此信息：
if (ournames[i]->attrs.flags & SSH_FILEXFER_ATTR_ACMODTIME) {
mtime = ournames[i]->attrs.mtime;
}
fzprintf(sftpListentry, "%lu %s", mtime, ournames[i]->longname);
米娜SSHD/SFTP（SftpSubsystemclass），在列出.和..meta-directories时，错误地使用了电流display-only 字符串中的文件夹名称和父文件夹名称，而不是 . 和 ..。它在结构化元数据（shortname 字段）中正确使用 . 和 ..。
FileZilla 从列表中读取了错误的名称并感到困惑，将条目视为实际的子目录条目，而不是 meta-directories。
在根目录中，.和..可能都列为/。 FileZilla 修剪所有内容，直到最后一个 /，导致空条目（并且两个 same-named [empty-named] 条目可能合并为一个）。
所以不用
.
..
upload
download
FileZilla 看到
/ [treated as an empty string]
/ [treated as an empty string and ignored as duplicate]
upload
download
在 upload 目录中，. 被列为 upload，.. 被列为 /（导致空条目）。
所以不用
.
..
FileZilla 看到
upload
/ [treated as an empty string]
WinSCP 相反，从不使用 display-only 字符串来解析 file/directory 名称。并且主要（如果服务器支持，Mina SSHD 所做的）使用 SFTP 版本 4，它甚至不包括 display-only 字符串。
要解决此问题，您需要将 SftpSubsystem.writeDirEntry 方法的 shortName 参数传递给被调用的 .getLongName 方法。并修改 .getLongName 以在字符串中使用 shortName returns 而不是 getShortName(f).
请参阅下面的 SftpSubsystem 修改代码，其中包含描述更改的注释。代码来自Mina SSHD version 1.0
protected void writeDirEntry(int id, DirectoryHandle dir, Buffer buffer, int index, Path f, String shortName, LinkOption... options) throws IOException {
...
if (version == SFTP_V3) {
// added shortName argument
String longName = getLongName(f, options, shortName);
} else {
...
}
// added shortName parameter
protected String getLongName(Path f, LinkOption... options, String shortName) throws IOException {
// added shortName argument
return getLongName(f, true, options, shortName);
}
// added shortName parameter
private String getLongName(Path f, boolean sendAttrs, LinkOption... options, String shortName) throws IOException {
...
// added shortName argument
return getLongName(f, attributes, shortName);
}
// added shortName parameter
private String getLongName(Path f, Map<String, ?> attributes, String shortName) throws IOException {
...
return (SftpHelper.getBool(isDirectory) ? "d" : (SftpHelper.getBool(isLink) ? "l" : "-"))
+ PosixFilePermissions.toString(perms) + " "
+ (attributes.containsKey("nlink") ? attributes.get("nlink") : "1")
+ " " + username + " " + group + " " + lengthString + " "
+ UnixDateFormat.getUnixDate((FileTime) attributes.get("lastModifiedTime"))
// using shortName instead of getShortName(f)
+ " " + shortName;
}
// + you need to modify sendPath to pass getShortName(f)
// to its call to getLongName
我不会Java，所以请原谅任何错误的代码。
考虑将错误报告给 Mina SSHD 项目。 Link这里的问题，如果你这样做。
