Issue
I want to run client and daemon application which responds to client in the same time.
Connection established to SSH using Paramiko. But I could not run both daemon and client in the same time.
How to do this with Paramiko?
Here the expectation is, client provide input as 1,2,3 and daemon responds to each input. Both run in the same SSH.
Could any one help me with this?
Solution
I assume you can use simple shell syntax to achieve what you need. You do not need any fancy code in Python/Paramiko.
Assuming *nix server, see How do I run multiple background commands in bash in a single line?
To run (any) command in Paramiko, see Execute command and wait for it to finish with Python Paramiko
So probably like this:
stdin, stdout, stderr = ssh_client.exec_command("deamon & client")
stdout.channel.set_combine_stderr(True)
output = stdout.readlines()
If you need to somehow run the two commands (deamon and clinet) independenty for a better control, you can start here:
Run multiple commands in different SSH servers in parallel using Python Paramiko
Except that you do not need to open multiple connections (SSHClient). You will just call SSHClient.exec_command twice on the same SSHClient instance.
