The main content of this article is to explain "what are the two ways for python to connect telnet and ssh". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "what are the two ways for python to connect telnet and ssh?"

Telnet connection method #! / usr/bin/env python# coding=utf-8 import timeimport telnetlibimport logging _ author__ = 'Evan' save_log_path =' result.txt'file_mode ='% (asctime) s -% (filename) s [line:% (lineno) d] -% (levelname) s:% (message) s' logger = logging.getLogger (_ _ name__) logger.setLevel (logging.DEBUG) # add record Recorder function fh = logging.FileHandler (save_log_path Mode=file_mode) fh.setLevel (logging.DEBUG) fh.setFormatter (logging.Formatter (format_info)) logger.addHandler (fh) # add display recorder function ch = logging.StreamHandler () ch.setLevel (logging.DEBUG) ch.setFormatter (logging.Formatter (format_info)) logger.addHandler (ch) def telnet_handle (host='', port=''): handle = telnetlib.Telnet (host, port) Timeout=10) handle.set_debuglevel (2) # Display connect info (send command & received info) logger.debug ('Connect host: {} port: {} successful'.format (host, port)) try: # get the login prompt' login:' and enter the password. Handle.read_until ('login:', timeout=5) # sends a command to log in, user name: admin password: admin handle.write (' admin\ n') # user name # if you have a prompt to enter a password, you can open this one. And fix the correct password prompt # handle.read_until ('enter password prompt' Timeout=5) time.sleep (1) handle.write ('admin\ n') # password time.sleep (1) handle.write ('en\ n') # execute instruction time.sleep (1) handle.write ('sys\ n') # execute instruction time.sleep (1) handle.write ('display running-config\ n') # execute Line instruction time.sleep (1) handle.write ('show stack\ n') # execute instruction time.sleep (1) # read all information result = handle.read_very_eager () logger.info ('Received info: {}' .format (result)) finally: handle.close () if _ _ name__ = ='_ _ main__ ': telnet_handle (host='192.168.10.1' Port='23') ssh connection method #! / usr/bin/env python# coding=utf-8 import paramiko,sys,time client = paramiko.SSHClient () client.set_missing_host_key_policy (paramiko.AutoAddPolicy ()) # connection to SSH server client.connect ("192.168.10.1", 22, "admin", "admin") # execution mode A connection to linux sends a fixed instruction stdin,stdout Stderr = client.exec_command ("whoami") time.sleep (2) print (stdout.read ()) stdin,stdout,stderr = client.exec_command ("cat / root/lzhi/c_call_python.txt") print (stdout.read ()) stdin,stdout,stderr = client.exec_command ("ls") print (stdout.read ()) stdin,stdout,stderr = client.exec_command ("ls-la") print (stdout.read ()) # way to get command line arguments And delete parameter 1.
