I’m having a problem with a ShoreTel voice switch, and I’m trying to use Paramiko to jump into it and run a couple commands. What I believe the problem might be, is that the ShoreTel CLI gives different prompts than the standard Linux $. It would look like this:
server1$:stcli Mitel>gotoshell CLI> (This is where I need to enter 'hapi_debug=1')
Is Python still expecting that $, or am I missing something else?
I thought it might be a time thing, so I put those time.sleep(1) between commands. Still doesn’t seem to be taking.
import paramiko
import time
keyfile = "****"
User = "***"
ip = "****"
command1 = "stcli"
command2 = "gotoshell"
command4 = "hapi_debug=1"
ssh = paramiko.SSHClient()
print('paramikoing...')
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(hostname = ip, username = User, key_filename = keyfile)
print('giving er a go...')
ssh.invoke_shell()
stdin, stdout, stderr = ssh.exec_command(command1)
time.sleep(1)
stdin, stdout, stderr = ssh.exec_command(command2)
time.sleep(1)
stdin, stdout, stderr = ssh.exec_command(command4)
time.sleep(1)
print(stdout.read())
ssh.close()
print("complete")
What I would expect from the successful execution of this code, would be for the hapi_debug level to be 1. Which means that when I SSH into the thing, I would see those HAPI debugs populating. When I do, I do not see those debugs.

Method 1
I assume that the gotoshell and hapi_debug=1 are not top-level commands, but subcommands of the stcli. In other words, the stcli is kind of a shell.
In that case, you need to write the commands that you want to execute in the subshell to its stdin:
stdin, stdout, stderr = ssh.exec_command('stcli')
stdin.write('gotoshelln')
stdin.write('hapi_debug=1n')
stdin.flush()
If you call stdout.read afterwards, it will wait until the command stcli finishes. What it never does. If you wanted to keep reading the output, you need to send a command that terminates the subshell (typically exitn).
stdin.write('exitn')
stdin.flush()
print(stdout.read())
