Greetings all, help solve the problem: there is a code

if switch in zhone: zhone_ip = zhone[switch] print (zhone_ip) paramiko.common.logging.basicConfig(level=paramiko.common.DEBUG) ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.RejectPolicy()) ssh.connect(hostname=zhone_ip, port=22, username='admin', password='zhone') channel = ssh.get_transport().open_session() channel.get_pty() channel.settimeout(5) channel.exec_command('onu status 1/7/52') print (channel.recv(1024)) channel.close() ssh.close() `

here is the exit:

What is the problem I do not understand, can you tell me?

Closed due to the fact that the question is too general for the user194374, cheops , Streletz , aleksandr barakin , fori1ton 6 Jul '16 at 8:16 .

Please correct the question so that it describes the specific problem with sufficient detail to determine the appropriate answer. Do not ask a few questions at once. See “How to ask a good question?” For clarification. If the question can be reformulated according to the rules set out in the certificate , edit it .

    Try to give minimal but complete code examples and the corresponding verbal description of what the code should do and what happens instead (what exactly is the conclusion that differs from the desired one and which of the several possible problems you are interested in). A more informative header doesn’t hurt: “Trying to ssh on a zphone using paramiko 2 results in ValueError: p must be exactly 1024, 2048, or 3072 bits long” - jfs
