Using MINA sshd 2.2.0
Hi All,
I am currently trying to migrate from JSCH to MINA sshd api's
Can you guys please let me know if there is any documentation about how
to migrate to MINA (mapping jsch to MINA api's)
As of now I am trying to execute a simple command /bin/uname and get its
out put
as below
try (ChannelExec channel = session.createExecChannel(command)){
Trace.out("opening the exec channel");
channel.open().awaitUninterruptibly();
//channel.setStreaming(ClientChannel.Streaming.Sync);
Trace.out("Streaming : " +
channel.getStreaming().toString());
InputStream in = channel.getInvertedOut();
<------------------------------------ get some object for which buffer
is never ready
InputStreamReader inStream = new InputStreamReader(in);
BufferedReader bufReader = new BufferedReader (inStream);
boolean isBufReady = bufReader.ready();
<----------------------------------------- buffer is never ready
if (isBufReady)
{
thisLine = bufReader.readLine();
if ((thisLine != null) && (!"".equals(thisLine)))
Trace.out ("read line is " + thisLine);
}
}
But I am unable to get the output in any of the streams getInvertedOut
and getIn
getIn always returns null
The purpose here is that we should be able to handle the cases
1] normal command execution and get the output
2] If the command propmts for a password we should be able to write it
and then get the output.
3] execute with key based authentication.
Please throw dome light on how to handle the Input and output streams
while using the MINSA sshd API's
Speedy response would be appreciated.
Thanks
Prajwal
