(host, username=user, password=psw, port=22) _missing_host_key_policy(paramiko.AutoAddPolicy()) I'm confused with this "non-determinism" and would very much appreciate your help. The second and third cd and ls commands (when printed) always appear before the first ls output.The first cd and ls commands are always present in the output (I get them via the recv command, as part of the output), while all the following cd and ls commands are printed sometimes, and sometimes they aren't.The first print doesn't always print the ls output (sometimes it is only printed on the second print).Ssh.connect(host, username=user, password=psw, port=22) Ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) The next option I looked into was implementing an interactive shell using paramikos' invoke_shell() function: ssh = paramiko.SSHClient() Thus, I want to execute commands in the same channel. After looking at paramikos' exec_command() function, I realized it's not suitable for my use case (because the channel gets closed after the command is executed), as the commands depend on environment variables (set by prior commands) and can't be concatenated into one exec_command() call as they are to be executed at different times in the program. The type of shell being used can be detected (BASH only).I want to write a program (in Python 3.x on Windows 7) that executes multiple commands on a remote shell via ssh. How to check which type of shell is being used? Scripts like Init and startup are considered non-interactive since they must run without human intervention. A shell that runs a script is always considered a non-interactive shell. This shell is generally a non-login shell because the calling user has logged in already. Non-interactive scripts can smoothly run in the background easily. It is highly recommended to use the full path for a command in non-interactive shells. The non-interactive shell influences the PATH variable. Also, it can be run through some automated process. We can run it through a script or similar. Non-interactive shell:Īs the name implies, a non-interactive shell is a type of shell that doesn’t interact with the user. We can start an interactive shell by giving the name of the shell after we logged into the system.
