Hi Yamanaka,
Thanks for your quick response .
Well, Please look in to my code that handles the shell connection and my
debug info at the point of reading and writing data in channel .
try {
channel_ = (ChannelShell)session_.openChannel("shell");
channel_.setPty(true);
channel_.setPtyType("vt100")
channel_.connect(1000);
we set the terminal mode as :
// These values were taken from a debug openssh session, compiled
with
// -DPACKET_DEBUG and run with the -vvv option. Mnemonic codes
are from
// RFC 4254 -- http://www.rfc-archive.org/getrfc.php?rfc=4254
} catch( JSchException ex ) {
}
// Reading and writing data
try {
InputStream in_ = channel_.getInputStream();
OutputStream out_ = channel_.getOutputStream();
} catch( java.io.IOException ioe ) {
//
}
// Writing data to channel
When a key stroke is presses , say example UP Arrow Key
( Key Pressed code : 38 ) , its code is generated and written in to the O/P
Stream in the from of bytes.
Flushes the data to the channels O/P Stream
KetStroke --> channels O/P Stream --> Remote Shell
// Reading data from channel
The response data in bytes is taken from the I/P Stream and processed to
VT100 Emulator Screen.
VT100 Emulator Screen <-- channels I/P Stream <-- Remote Shell
ISSUE :
For UP Arrow key , response data taken from I/P Stream is normal when i
connect to a remote shell .
For UP Arrow key , response data taken from I/P Stream is abnormal when i
connect to a Galaxy Service Processor . I always get the value "A" rather
than the exact data .
Note :
1. I tried vt102 , also ends with the same issue
The above code and debug information might have given you the clear
visibility of the issue .
Awaiting your reply .
Thanks,
S E N TH I L
