Somehow I am able execute command remotely but not able to run interactive.
I have read this document -
********************************************
Running an interactive command/shell
If one needs to parse the command/shell output and then respond by sending
the correct input, the code must use separate thread(s) to read the
STDOUT/STDERR and provide STDIN input. These threads must be up and running
before opening the channel since data may start to pour in even before the
await/verify call returns. If this data is not consumed at a reasonable pace,
then channel may block and eventually even disconnect. Thus the thread(s) using
the streams must be ready beforehand.
// The same code can be used when opening a ChannelExec in order to run a
single interactive command
try (ClientChannel channel = session.createShellChannel(/* use internal
defaults */)) {
channel.setIn(...stdin...);
channel.setOut(...stdout...);
channel.setErr(...stderr...);
...spawn the servicing thread(s)....
try {
channel.open().verify(...some timeout...);
// Wait (forever) for the channel to close - signalling shell exited
channel.waitFor(EnumSet.of(ClientChannelEvent.CLOSED), 0L);
} finally {
// ... stop the pumping threads ...
}
}
In such cases it is recommended to use the inverted streams in the relevant
threads
// The same code can be used when opening a ChannelExec in order to run a
single interactive command
try (ClientChannel channel = session.createShellChannel(/* use internal
defaults */)) {
try {
channel.open().verify(...some timeout...);
spawnStdinThread(channel.getInvertedIn());
spawnStdoutThread(channel.getInvertedOut());
spawnStderrThread(channel.getInvertedErr());
// Wait (forever) for the channel to close - signalling shell exited
channel.waitFor(EnumSet.of(ClientChannelEvent.CLOSED), 0L);
} finally {
// ... stop the pumping threads ...
}
}
********************************************
I couldn't understand how to read and write commands in different threads.
It would be great If any one could write a sample code.
