Constructor Detail

ServerUserAuthService

public ServerUserAuthService(Session s)
                      throws java.io.IOException

Throws:

java.io.IOException

Method Detail

getWelcomePhase

public WelcomeBannerPhase getWelcomePhase()

start

public void start()

Specified by:

start in interface Service

getSession

public ServerSession getSession()

Specified by:

getSession in interface SessionHolder<Session>

getServerSession

public ServerSession getServerSession()

Specified by:

getServerSession in interface ServerSessionHolder

Returns:

The underlying ServerSession used

getProperties

public java.util.Map<java.lang.String,java.lang.Object> getProperties()

Description copied from interface: PropertyResolver

A map of properties that can be used to configure the SSH server or client. This map will never be changed by either the server or client and is not supposed to be changed at runtime (changes are not bound to have any effect on a running client or server), though it may affect the creation of sessions later as these values are usually not cached.

Note: the type of the mapped property should match the expected configuration value type - Long, Integer, Boolean, String, etc.... If it doesn't, the toString() result of the mapped value is used to convert it to the required type. E.g., if the mapped value is the string "1234" and the expected value is a long then it will be parsed into one. Also, if the mapped value is an Integer but a long is expected, then it will be converted into one.

Specified by:

getProperties in interface PropertyResolver

Returns:

a valid Map containing configuration values, never null. Note: may be immutable.

process

public void process(int cmd,
                    Buffer buffer)
