GH-403: Fix SFTP handle size Change the file handle implementation: use raw bytes, not hexified bytes. Representing file handles internally as hexified strings doubled the size, so with the default setting of 16, an Apache MINA file handle was actually 32 bytes on the network. SftpModuleProperties.FILE_HANDLE_SIZE specified that its the size in bytes of the file handle; so the final handle as sent to the client should not be twice the configured size. Because many APIs in Apache MINA sshd use String as the type to pass around such file handles, we cannot easily change that without potentially breaking a lot of user code. So keep storing file handles as strings, but use ISO-8859-1 to convert: this lets us store any byte value as a character. When printing file handles, for instance in log messages, hexify them explicitly. Bug: https://github.com/apache/mina-sshd/issues/403
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:
AsynchronousSocketChannel
s.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
