Susmit Sarkar commented on SSHD-1209:
-
*perhaps you are writing some UNICODE data but reading it as ASCII instead of
UTF-8 on the peer side* = Reading is done by the ssh client in my case Putty
*That means that it is UTF-8 encoded* = yes it is UTF-8 encoded
*you are not reading the data as a {{ByteBufferArray}}*
{code:java}
ByteArrayBuffer buf = new ByteArrayBuffer();
buf.putString(refinedUserExitMessage + System.getProperty("line.separator"));
errStream.writeBuffer(buf);{code}
What is the solution shall i follow?

You are writing the string to a {{ByteBufferArray}} and that means that it is
UTF-8 encoded - perhaps you are writing some UNICODE data but reading it as
ASCII instead of UTF-8 on the peer side. Another possibility is that you are
not reading the data as a {{ByteBufferArray}} - reminder: when writing a
string, its length is written as a 32-bit value before the (UTF-8) characters
was (Author: lgoldstein):

Welcome to the community
The version is 2.7.0 it's mentioned above.
You can have a look at this class
[https://github.com/apache/mina-sshd/blob/2fc98f7a21a7b83d2b2bc72d48a2194caa7f8fd1/sshd-contrib/src/main/java/org/apache/sshd/contrib/server/subsystem/sftp/DetailedSftpErrorStatusDataHandler.java]
only difference is I have implemented is adding few more interfaces:
ChannelSessionAware, AsyncCommandErrorStreamAware, CommandDirectErrorStreamAware
to write any sftp related exception to the command line output, and have
overrwritten few default methods
resolveErrorMessage() and setIoErrorStream(IoOutputStream errStream)

Hi Susmit,
I am new to the community. Could you please do let me know which version to
check out from. And provide any documentation. I can start looking at the
issues ASAP.
Thanks in advance.

@Override
public void setIoErrorStream(IoOutputStream errStream) {
this.errStream = errStream;
}

finally we are writing to the error stream:
{code:java}
private void writeMsgToErrorStream(String refinedUserExitMessage) {
ByteArrayBuffer buf = new ByteArrayBuffer();
buf.putString(refinedUserExitMessage +
System.getProperty("line.separator"));
try { if (errStream != null) {

}
} catch (Exception e) {

}
{code}
Once the data is written to error stream we are gettig proper message to the

But there is an extra charater getting appended at the first character *<*
Utils.java
I have no idea from where this *<* is coming from, and that changes with the
first character like if it is P it would be *>, when starting with S it gets
appended with Z*
Any help will be appreciated.

DetailedSftpErrorStatusDataHandler implements SftpErrorStatusDataHandler,
ChannelSessionAware, DetailedSftpErrorStatusDataHandler implements
SftpErrorStatusDataHandler, ChannelSessionAware, AsyncCommandErrorStreamAware,
CommandDirectErrorStreamAware {
{code}
and we have overridden the :
resolveErrorMessage and setIoErrorStream(IoOutputStream errStream)
{code:java}
@Override
public void setIoErrorStream(IoOutputStream errStream) {
this.errStream = errStream;
}
{code}
finally we are writing to the error stream:
{code:java}
private void writeMsgToErrorStream(String refinedUserExitMessage) {
ByteArrayBuffer buf = new ByteArrayBuffer();
buf.putString(refinedUserExitMessage +
System.getProperty("line.separator"));
try { if (errStream != null) {
errStream.writeBuffer(buf);
}
} catch (Exception e) {
}
}
{code}
Once the data is written to error stream we are gettig proper message to the
console:
!image-2021-08-19-12-50-01-922.png!
But there is an extra charater getting appended at the first character
*<*Utils.java
I have no idea from where this *<* is coming from, and that changes with the
first character like if it is P it would be *>, when starting with S it gets
appended with Z*
Any help will be appreciated.
Thanks,
Susmit
