kandi X-RAY | mina-sshd Summary
Apache SSHD is a 100% pure java library to support the SSH protocols on both the client and server side. This library can leverage Apache MINA, a scalable and high performance asynchronous IO library. SSHD does not really aim at being a replacement for the SSH client or SSH server from Unix operating systems, but rather provides support for Java based applications requiring SSH support.

QUESTION
I am writing an SFTP client using the Apache Mina SSHD library, specifically sshd-sftp 2.3.0. I chose it instead of the SSHJ library, because it is possible to write a String to a remote file directly, and there are also no unnecessary dependencies.
The task: when sending files to the SFTP server to make a backup copy of the previous file, if any.
I studied all the possibilities that the SftpClient class provides, and among them I did not find an easy way to search for a file.
- There are
listDirandreadDirmethods, they returnIterable, but I suspect that with a large number of files they will work slowly. - We can simply force a file to be renamed using the
renamemethod, but in my case there can be many backup files, and we must first find a free file name.
The current solution is to get the state of the file. If there is no such file, then a SftpException will be thrown, for example, "SFTP error (SSH_FX_NO_SUCH_FILE): No such file or directory". This message can be analyzed, and if the file is really not found, then just don't throw this exception further. Here is the code:
ANSWER
Answered 2019-Sep-06 at 10:33That is the correct solution.
SFTP protocol does not have a "does a file exist" query/request. The nearest equivalent is actually the "stat" query/request. So even if your favourite SFTP library had "does a file exist" method/API, it would internally do, what your code does.
An equivalent in JSch: Using JSch, is there a way to tell if a remote file exists without doing an ls?

I am trying to setup a simple SFTP server using Apache Mine SSHD v1.2.0.
I have looked at several examples on the web E.g. here, here and here.
However they all have the same line in common which I cannot get NetBeans to resolve. NetBeans tells me that it cannot find Factory in SftpSubsystem. The line in question looks as follows:

In Apache Mina SSHD Github documentation https://github.com/apache/mina-sshd#configuring-the-server-instance we can see section "KeyPairProvider".
In this section we can see
It's usually a good idea to save generated keys, so that if the SSHD server is restarted, the same keys will be used to authenticate the server and avoid the warning the clients might get if the host keys are modified.
My question is how to save generated keys because every time when I make restart server in Terminal I can see message
