SftpFileSystem: keep a session until the filesystem is closed When an SftpFileSystem is obtained via FileSystems.newFileSystem(URI), the new file system is created with an implicit SshClient and a new implicit ClientSession. This session has a heartbeat set to keep it open for the lifetime of the file system, i.e., until the file system is closed. But heartbeats do not guarantee that the session remains open. A server may decide all the same to close the session, for instance, if it is idle for too long. (Even despite heartbeat messages.) So ensure that in such a case, the file system automatically tries to open a new session. Otherwise a client of such an SftpFileSystem must be prepared to deal with these cases at any time, which may be difficult or even impossible to do.
Apache MINA SSHD is a 100% pure java library to support the SSH protocols on both the client and server side. It does not 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.
The library can leverage several I/O back-ends:
AsynchronousSocketChannels.Releases of Apache MINA sshd are available at Maven Central. tar.gz and ZIP source and binary distributions are available at the Apache MINA sshd web site.
Snapshot releases from the main branch are published on each push or merge on the main branch, if the tests pass successfully. These snapshot releases are available at the Apache Snapshot maven repository.
Bug reports and improvement or feature requests can be filed at the GitHub issue tracker or at the Apache issue tracker.
Sensitive issues such as security vulnerabilities must be reported through private channels, not via either issue tracker.
Java 8+ (as of version 1.3)
The code only requires the core abstract slf4j-api module. The actual implementation of the logging API can be selected from the many existing adaptors.
sshd-common - contains basic classes used throughout the project as well as code that does not require client or server network support.
sshd-core - contains the basic SSH client/server code implementing the connection, transport, channels, forwarding, etc..
sshd-sftp - contains the server side SFTP subsystem and the SFTP client code.
sshd-scp - contains the server side SCP command handler and the SCP client code.
sshd-ldap - contains server-side password and public key authenticators that use an LDAP server.
sshd-git - contains replacements for JGit SSH session factory.
sshd-osgi - contains an artifact that combines sshd-common and sshd-core so it can be deployed in OSGi environments.
sshd-putty - contains code that can parse PUTTY key files.
sshd-openpgp - contains code that can parse OpenPGP key files (with some limitations - see relevant section)
sshd-cli - contains simple templates for command-line client/server - used to provide look-and-feel similar to the Linux ssh/sshd commands.
sshd-contrib - experimental code that is currently under review and may find its way into one of the other artifacts (or become an entirely new artifact - e.g., sshd-putty evolved this way).
Including tests
mvn clean install
Without tests
mvn -Pquick clean install
