![]() python -c import pty pty.spawn(/bin/bash). You can also create a user normally, in anyway you want (which I assume you know already?), then edit /etc/passwd like in msw's answer. Spawn /bin/bash using Pythons PTY module, and connect the controlling shell with its standard I/O. On how to create such a user, if you skim through man useradd there is an option to set the login shell, -s or -shell. Foreground the shell with fg and re-open the shell with reset. ![]() You can read more here (this document is for bash, but the same concept applies for other shells). Set the current STTY to type raw and tell it to echo the input characters. Some commands behave differently depending on whether the shell is run interactively or non-interactively. ![]() Break your own console to achieve a full interactive TTY shell. It can be used to a automate setup scripts for duplicating software package installations on different servers. Pexpect can be used for automating interactive applications such as ssh, ftp, passwd, telnet, etc. There is also the non-interactive mode, where the user saves a series of commands they want to run in a file (called a shell script), and executes the file afterwards. Finally if all of the above things fail, you still have one more option. Pexpect is a Python module for spawning child applications and controlling them automatically. The word "interactive" doesn't really add any information to the question, because as long as there is a user typing commands, the shell session is interactive. Interactive describe the way the shell works: the user types something, and the shell does something accordingly (there is a kind of communication between the user and the shell). The question means "Create a user named john who won't be able to log in and run commands from a shell". Subprocess Module code: from subprocess import *Ĭommand = '/Applications/Utilities/Terminal.Regarding the question you are trying to answer:Ĭreate a user john who should not get an interactive shell. I have tried the subprocess module in python to spawn multiple terminal windows, and that works fine, however I know subprocess doesn't handle ssh as well as pexpect. Ssh_tunnel2 = pexpect.spawn("/Applications/Utilities/Terminal.app/Contents/MacOS/Terminal") When I try to do this: ssh_tunnel = pexpect.spawn("/Applications/Utilities/Terminal.app/Contents/MacOS/Terminal") I am also seeing an issue trying to spawn multiple windows. The problem that I am seeing is that I'm able to open up a new terminal application, however, no commands are running on that terminal. from import readlogin from Exscript.protocols import SSH2 account readlogin () conn SSH2 () nnect ('192.168.1.1') conn.login (account) while True: command rawinput ('cli: ') if command 'q': break conn.execute (command) print conn.response nd ('quit\r') conn. If SSH access is allowed at the deployment, space, and app level, you can run the cf ssh APP-NAME command to start an interactive SSH session with a VM. There are cases when we want to test our local code if it runs on remotely. Send a separate ssh command to each of the terminal windows (each will ssh into a different host, and run another command)Ĭommand = "/Applications/Utilities/Terminal.app/Contents/MacOS/Terminal ssh = pexpect.spawn (command) Bookmark and Share site search: Remote run.Open multiple terminal windows (on Mac) to display outputs.I am trying to use Python and the Pexpect module to do two things:
