Remote ssh connection to confD

General
1

I’m trying to launch a ssh session to confD from a remote machine. I get a “connection closed by remote host” message. How can I connect to the confD terminal remotely via SSH?

I have ssh configured in confd.conf file as follows

<ssh>
  <enabled>true</enabled>
  <ip>0.0.0.0</ip>
  <port>2024</port>
</ssh>

Command which I used to launch ssh session to confD:
ssh -s -p 2024 admin@ConfD Server IP cli

When you login to the remote machine, can you SSH to ConfD CLI locally?
If you add -vvv to ssh, do you get any additional info?

I get the following info below
I attempted to ssh to confD from local machine using this command below

ssh -vvv -s -p 2024 vamsi@localhost cli

After successful authentication I get this message below

Unless you are using OpenSSH instead of ConfD’s built in ssh server, remove the subsystem cli flag “-s cli” and the connection will not be closed by the ConfD ssh server.

Thanks for the response. I can now ssh to ConfD
