How to use CommandFactory
Hello,
I have a working server with a shell implementation and I want to improve
it with a command. I want to use the command to receive parameters in the
shell:
ssh user@server param1 param2
And in both cases open an interactive shell. I have instructed the 2
factories (Command and Shell) to create instances of the same class.
However I see slightly different behaviours. With the console factory it
looks like the commands I input are echoed.
Reading the documentation, there is a mention that the channel types are
different.
https://github.com/apache/mina-sshd/blob/master/docs/server-setup.md
[...]
CommandFactory - The CommandFactory provides the ability to run a *single*
direct command at a time instead of an interactive session (it also uses a
*different* channel type than shells). It can be used *in addition* to the
ShellFactory.
[...]
Could you please explain the different types?
Many thanks!!

After a quick investigation, it looks like the differences came from the
client side.
Using openssh client with a command requires the -t option (Force
pseudo-terminal allocation).
Without a command enables this option by default.

I see that with the shell factory y get this from the ssh client:
debug1: ENABLE_VIRTUAL_TERMINAL_INPUT is supported. Reading the VTSequence
from console
debug1: ENABLE_VIRTUAL_TERMINAL_PROCESSING is supported. Console supports
the ansi parsing
which I dont get with the command factory.
how can i make the command factory work like the shell factory?
