net.schmizz.sshj.sftp.SFTPException: No such file

sibiarunachalam commented 6 years ago

sshj version: 0.21.0 Client: Linux SSH Server: Linux Or Windows (Tested in both OS) Code:

SSHClient sshClient = new SSHClient();
sshClient.addHostKeyVerifier("hostKeyVerifier");
sshClient.authPassword("foouser", "fooPassword");
sshClient.newSFTPClient().get("fooDir", "/home/baruser/temp");

Exception:

Note: It works with SCPFileTransfer

It looks purely SSH Server configuration problem. It worked in Windows after setting Mount Points in SSH Server

But, I didn't get any clue for Linux. It throws same exception when I try to get files in "fooDir" from foouser's HOME dir I expect, sshj should get "fooDir" from user's home directory by default

I'm not sure I'm following you. Can you write a clear problem description?

Don't know whether this was @sibiarunachalam's issue, as the stack trace is slightly different, and I'm trying to get a regular file, not a directory, but I just worked through the following thing that sounds similar:

sftpClient.put("./local_file.txt", "remote_file.txt") succeeds.
The result is that the remote file is in /somedir/remote_file.txt, where /somedir is the user's default remote working directory.
sftpClient.get("remote_file.txt", "./whatever.txt") fails with SFTPException: No such file, stacktrace below.
sftpClient.open("remote_file.txt").read(...) succeeds. This is what I'm now using.
sftpClient.canonicalize("remote_file.txt") fails with SFTPException: No such file.

In debugging I found that both canonicalize and get internally result in an attempt to use the path /remote_file.txt—note the incorrect leading /.

Edit: I also confirmed that sftpClient.get("/somedir/remote_file.txt", "./local.txt") succeeds, but I didn't see a way to determine the canonical remote path programmatically.

Which version are you using?

duelinmarkers commented 5 years ago

com.hierynomus:sshj:0.26.0

Also, I found that ./remote_file.txt works, just not remote_file.txt.
