Python Paramiko send CTRL+C to an ssh shell

问题

I'm invoking a shell using Paramiko in order to use a CLI over an ssh connection. The problem with this CLI is if I do not close it specifically using CTRL+C, the program will not be able to be opened again without rebooting my system.

I've tried the below commands:

SSH.send("^C\n")
SSH.send("\x003")

is there another way to call these? Again, I've established an SSH connection using paramiko.SSHClient() and then invoked a shell using ssh.invoke_shell() and now i need to send CTRL+C to that shell to close the shell (not the ssh connection)

回答1:

You're on the right track with your second example, but it isn't quite formatted right. You're actually getting a 2 character string there.

SSH.send("\x03") should do the trick.

However, I'd probably have used this instead.

SSH.send(chr(3))

You can -
either: pass get_pty=True when calling client.exec_command(). Then client.close() terminates the remote tail.
or: do channel.get_pty() before calling channel.exec_command(). Then channel.close() terminates the remote tail.
