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)
SSHClient. A high-level representation of a session with an SSH server. This class wraps Transport , Channel , and SFTPClient to take care of most aspects of authenticating and opening channels. A typical use case is: client = SSHClient() client.
In python SSH is implemented by using the python library called fabric. It can be used to issue commands remotely over SSH.
Using exec_command() in Paramiko returns a tuple (stdin, stdout, stderr) . Most of the time, you just want to read stdout and ignore stdin and stderr . You can get the output the command by using stdout. read() (returns a string) or stdout.
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.
