Examples of RLoginClient

org.apache.commons.net.bsd.RLoginClient
RLoginClient is very similar to {@link org.apache.commons.net.bsd.RCommandClient}, from which it is derived, and uses the rcmd() facility implemented in RCommandClient to implement the functionality of the rlogin command that first appeared in 4.2BSD Unix. rlogin is a command used to login to a remote machine from a trusted host, sometimes without issuing a password. The trust relationship is the same as described in the documentation for {@link org.apache.commons.net.bsd.RCommandClient}.
As with virtually all of the client classes in org.apache.commons.net, this class derives from SocketClient. But it relies on the connection methods defined in RcommandClient which ensure that the local Socket will originate from an acceptable rshell port. The way to use RLoginClient is to first connect to the server, call the {@link #rlogin rlogin() } method,and then fetch the connection's input and output streams. Interaction with the remote command is controlled entirely through the I/O streams. Once you have finished processing the streams, you should invoke {@link org.apache.commons.net.bsd.RExecClient#disconnect disconnect() }to clean up properly.
The standard output and standard error streams of the remote process are transmitted over the same connection, readable from the input stream returned by {@link org.apache.commons.net.bsd.RExecClient#getInputStream getInputStream() }. Unlike RExecClient and RCommandClient, it is not possible to tell the rlogind daemon to return the standard error stream over a separate connection. {@link org.apache.commons.net.bsd.RExecClient#getErrorStream getErrorStream() }will always return null. The standard input of the remote process can be written to through the output stream returned by {@link org.apache.commons.net.bsd.RExecClient#getOutputStream getOutputSream() }.
