Class JschConfigSessionFactory

java.lang.Object

org.eclipse.jgit.transport.SshSessionFactory

org.eclipse.jgit.transport.JschConfigSessionFactory

public class JschConfigSessionFactory
extends SshSessionFactory

The base session factory that loads known hosts and private keys from $HOME/.ssh.

This is the default implementation used by JGit and provides most of the compatibility necessary to match OpenSSH, a popular implementation of SSH used by C Git.

The factory does not provide UI behavior. Override the method configure(org.eclipse.jgit.transport.OpenSshConfig.Host, Session) to supply appropriate UserInfo to the session.

Method Details

getSession

public RemoteSession getSession(URIish uri,
 CredentialsProvider credentialsProvider,
 FS fs,
 int tms)
                         throws TransportException

Opens (or reuses) a session to a host. The returned session is connected and authenticated and is ready for further use.

Specified by:

getSession in class SshSessionFactory

Parameters:

uri - URI of the remote host to connect to

credentialsProvider - provider to support authentication, may be null if no user input for authentication is needed

fs - the file system abstraction to use for certain file operations, such as reading configuration files

tms - connection timeout for creating the session, in milliseconds

Returns:

a connected and authenticated session for communicating with the remote host given by the uri

Throws:

TransportException - if the session could not be created

getType

public String getType()

Description copied from class: SshSessionFactory

The name of the type of session factory.

Specified by:

getType in class SshSessionFactory

Returns:

the name of the type of session factory.

createSession

protected com.jcraft.jsch.Session createSession(OpenSshConfig.Host hc,
 String user,
 String host,
 int port,
 FS fs)
                                         throws com.jcraft.jsch.JSchException

Create a new remote session for the requested address.

Parameters:

hc - host configuration

user - login to authenticate as.

host - server name to connect to.

port - port number of the SSH daemon (typically 22).

fs - the file system abstraction which will be necessary to perform certain file system operations.

Returns:

new session instance, but otherwise unconfigured.

Throws:

com.jcraft.jsch.JSchException - the session could not be created.

configureJSch

protected void configureJSch(com.jcraft.jsch.JSch jsch)

Provide additional configuration for the JSch instance. This method could be overridden to supply a preferred IdentityRepository.

Parameters:

jsch - jsch instance

Since:

4.5

configure

protected void configure(OpenSshConfig.Host hc,
 com.jcraft.jsch.Session session)

Provide additional configuration for the session based on the host information. This method could be used to supply UserInfo.

Parameters:

hc - host configuration

session - session to configure

getJSch

protected com.jcraft.jsch.JSch getJSch(OpenSshConfig.Host hc,
 FS fs)
                                throws com.jcraft.jsch.JSchException

Obtain the JSch used to create new sessions.

Parameters:

hc - host configuration

fs - the file system abstraction which will be necessary to perform certain file system operations.

Returns:

the JSch instance to use.

Throws:

com.jcraft.jsch.JSchException - the user configuration could not be created.

createDefaultJSch

protected com.jcraft.jsch.JSch createDefaultJSch(FS fs)
                                          throws com.jcraft.jsch.JSchException

Create default instance of jsch

Parameters:

fs - the file system abstraction which will be necessary to perform certain file system operations.

Returns:

the new default JSch implementation.

Throws:

com.jcraft.jsch.JSchException - known host keys cannot be loaded.
