Lyor Goldstein commented on SSHD-1283:
--------------------------------------
There are +3+ things to take care of if you want to disable remote command
execution and/or interactive shell while leaving only SCP and SFTP active.
Before calling {{SshServer#start}}
# call {{SshServer#setCommandFactory(null)}}
# call {{SshServer#setShellFactory(null)}}
# create a +new+ {{ScpCommandFactory}} that overrides the methods below and use
it instead of the default
{code:java}
@Override
public ShellFactory selectShellFactory(ChannelSession channelSession)
throws IOException {
return null;
}
@Override
public Command createShell(ChannelSession channel) throws IOException {
return null;
}
{code}
In SSHD-1009 we introduced an {{ScpShell}} that provides a +limited+ set of
commands in order to use {{WinSCP}} and this shell might be what is providing
the interactive capabilities (provide you took care of the other 2 setups).
+Note though:+ if you do as I suggested then you will +not+ be able to use
{{WinSCP}} with SCP (only with SFTP) as it relies on a +combination+ of SHELL
and SCP...

> Hi Team,
> We have implemented sftp server where we are giving SFTP and SCP both
> support.
> Both are working fine if we connected via winscp or any terminal client like
> putty etc.
>
> But if we use ssh command *ssh <userName>@localhost -p <port>*
> then it goes to interactive mode and exposes the current program running
> directory to do all operations(screenshot shows dir command) (sftp is showing
> correct directory as C:/ )
>
> !image-2022-07-28-17-25-36-368.png|width=462,height=485!
>
> So just wanted to check if can we just disable the above ssh command and
> still we can use scp and sftp? any help appreciated.
> May be this fix is causing the problem? :
> https://issues.apache.org/jira/browse/SSHD-1009,
> I have attached the sample code.
