阻止Paramiko打印到控制台

Question

When I connect a Paramiko client, I get output I don't need:

Connected (version 2.0, client OpenSSH_7.2p2)
Authentication (publickey) failed.
Authentication (publickey) failed.
Authentication (password) successful!

I tried to suppress the stdout as suggested in this question , but it doesn't work:

sys.stdout = open(os.devnull, "w")
print("AAAAAAAAAAAaaaaaaaaaaaaaaaaa")        
my_client.connect(hostname=hostname, username=username, password=password)
sys.stdout = sys.__stdout__

The "AAAAAAAAAAAaaaaaaaaaaaaaaaaa" does NOT appear, but the output from Paramiko still does. How do I stop Paramiko's info from printing to the console?

Answer 1

Paramiko does not print anything to the console on its own.

Paramiko sends those messages to a logger ( logging module ). If they end up on the console, you must have a logger configured that sends the log messages to the console.
