Let me see if I could put some more details around this.
So I have two problems. I think they are around PtyModes.
1. The carriage return is not honored no matter what I options I use. I’m just
simply trying to get it to work in Mac/Linux environment. Unless I specifically
add \r\n it does not want to work.
2. When I type in a regular SSH session, I see characters as I type them. In
Apache SSHD, I don’t see my input, but once I enter, it does send it over for
execution.
So I have created a custom ShellFactory and Command, that will execute Java
code on the input provided in the shell.
private class CLIShellFactory implements ShellFactory {
public Command createShell(ChannelSession channelSession) {
return new CLIShell();
}
private class CLIShell implements Command, Runnable {
At first I was using regular InputStream and OutpuStream, but then I saw some
code using TtyFilterInputStream and TtyFilterOutputStream, so I tried to
convert my code to use these, and provide PtyModes. But I’m still having issues
with it. Also, the TtyFilterOutputStream requires the following for echo to
work:
public TtyFilterOutputStream(OutputStream out, TtyFilterInputStream echo,
Collection<PtyMode> ttyOptions) {
If I use TtyFilterInputStream echo and set my InputStream, I will get into an
infinite loop! So I have set it to null, and removed PtyMode.ECHO, but I do
need it.
Any light on what I’m doing wrong here?
Is there a ShellFactory where I can just override one method and execute my
custom Java code which will enable me to have proper new lines and carriage
returns and echo enabled?
I would really appreciate someone who has experience with this to give me some
guidance. I have searched the web and cannot seem to find anything.
I did find this that I think has similar problem, which was old thread:

Hope someone can help…
