In my Paramiko/Python script, I need to receive broken data by lines. This data will be displayed on a web page. When I try this, the result appears on a single line, although it is several lines. How can I get this data separated by lines?
Follow the script below:
import threading, paramiko
import time
import sys
#==========================
command = sys.argv[1]
command2 = sys.argv[2]
command3 = sys.argv[3]
command4 = sys.argv[4]
command5 = sys.argv[5]
command6 = sys.argv[6]
command7 = sys.argv[7]
command8 = sys.argv[8]
command9 = sys.argv[9]
command10 = sys.argv[10]
#==========================
print("<html><head>")
print("</head><body>")
class ssh:
shell = None
client = None
transport = None
def __init__(self, address, username, password):
# print(("Connecting to server on ip", str(address) + "."))
self.client = paramiko.client.SSHClient()
self.client.set_missing_host_key_policy(paramiko.client.AutoAddPolicy())
self.client.connect(address, username=username, password=password, look_for_keys=False)
self.transport = paramiko.Transport((address, 22))
self.transport.connect(username=username, password=password)
thread = threading.Thread(target=self.process)
thread.daemon = True
thread.start()
def close_connection(self):
if(self.client != None):
self.client.close()
self.transport.close()
def open_shell(self):
self.shell = self.client.invoke_shell()
def send_shell(self, command):
if(self.shell):
self.shell.send(command + "\n")
else:
print("<h1>Shell não aberta.</h1>")
def process(self):
global strdata, fulldata
while True:
# Print data when available
if self.shell is not None and self.shell.recv_ready():
alldata = self.shell.recv(1024)
while self.shell.recv_ready():
alldata += self.shell.recv(1024)
strdata = strdata + str(alldata)
fulldata = fulldata + alldata.decode("UTF-8")
strdata = self.print_lines(strdata) # print all received data except last line
def print_lines(self, data):
last_line = data
if '\n' in data:
lines = data.splitlines()
for i in range(0, len(lines)-1):
print((lines[i]))
last_line = lines[len(lines) - 1]
if data.endswith('\n'):
print(lines.split(last_line))
last_line = ''
return last_line
sshUsername = "admin"
sshPassword = "password"
sshServer = "192.168.40.169"
connection = ssh(sshServer, sshUsername, sshPassword)
connection.open_shell()
connection.send_shell(command)
connection.send_shell(command2)
connection.send_shell(command3)
connection.send_shell(command4)
connection.send_shell(command5)
connection.send_shell(command6)
connection.send_shell(command7)
connection.send_shell(command8)
connection.send_shell(command9)
connection.send_shell(command10)
time.sleep(1)
print(fulldata) # This contains the complete data received.
connection.close_connection()
print("</body></html>")
Note the HTML header. I think I should put a 'br /' tag somewhere, but I’m not getting it.
The result should be:
R5#en
R%#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R5(config)#hostname R5
R5(config)#
But you’re bringing this:
R5#en R5#conf t Enter configuration commands, one per line. End with CNTL/Z. R5(config)#hostname R5 R5(config)#
