Help, I cannot figure out how to set starting folder of SFTP server.
Specifically, I have a web service that is able to transfer files to a SFTP
server and I want to use Mina/HTTPD to host a temporary server just for
unit test purpose. So, therfore I want the FTP server to host files in my
project root, and not show files outside of my project root.
For example, this doesn't work for me. I get an error:
sshd.setFileSystemFactory(new
VirtualFileSystemFactory(Paths.get("src/test/resources")));
And the error I get when trying to connect is:
20: Invalid filename
at com.jcraft.jsch.ChannelSftp.throwStatusError(ChannelSftp.java:2873)
at com.jcraft.jsch.ChannelSftp._realpath(ChannelSftp.java:2367)
at com.jcraft.jsch.ChannelSftp.getHome(ChannelSftp.java:2437)
Note: If I don't set the VirtualFileSystemFactory at all, then I can ftp
files to my server with no error but the server root is my entire file
system, which is NOT desirable.
One thing I tried was this, which explains the desired behavior I want, but
it I get a compile error (Error:(97, 13) java: method does not override or
implement a method from a supertype) :
sshd.setFileSystemFactory(new VirtualFileSystemFactory() {
@Override
protected Path computeRootDir(Session session) throws
IOException {
return Paths.get(".");
}
});
My Maven deps are:
<dependency>
<groupId>org.apache.sshd</groupId>
<artifactId>apache-sshd</artifactId>
<version>1.7.0</version>
<type>pom</type>
</dependency>
<dependency>
<groupId>com.jcraft</groupId>
<artifactId>jsch</artifactId>
<version>0.1.54</version>
</dependency>
My basic setup is:
sshd = SshServer.setUpDefaultServer();
sshd.setPort(port);
sshd.setKeyPairProvider(new
SimpleGeneratorHostKeyProvider(Paths.get(PUBLIC_CERT_FILE)));
sshd.setSubsystemFactories(Arrays.asList(new SftpSubsystemFactory()));
sshd.setCommandFactory(new ScpCommandFactory());
sshd.setPasswordAuthenticator(new LenientPasswordAuthenticator());
sshd.setPublickeyAuthenticator(new LenientPublicKeyAuthenticator());
