exscript ssh on python | 易学教程

问题

Im having problem with the exscript, i want to ssh to my cisco switches, but im having some trouble

I wrote 2 scripts,

with this one I dont have any problem, I can change the default gateway just by running the script and entering the user and password:

from Exscript.util.interact import read_login
from Exscript.protocols import SSH2

account = read_login()
enter code here`conn = SSH2()
conn.connect('192.168.86.12')
conn.login(account)
conn.execute('conf t')
conn.execute('no ip default-gateway')
conn.execute('ip default-gateway 192.168.68.10')

print "Response was:", repr(conn.response)
conn.send('exit\r')
conn.close()

But the problem comes here. I want to make it automatic, I dont want to enter the user and password by hand. So I wrote this script,

from Exscript.util.interact import read_login
from Exscript.protocols import SSH2

#account = read_login()
conn = SSH2()
conn.connect('192.168.86.12')
conn.login('user','password')
conn.execute('conf t')
conn.execute('no ip default-gateway')
conn.execute('ip default-gateway 192.168.68.10')

print "Response was:", repr(conn.response)
conn.send('exit\r')
conn.close()

But it gives me this error output..

Traceback (most recent call last):
File "nn.py", line 7, in <module>
conn.login('user','password')
File "/usr/local/lib/python2.7/dist-packages/Exscript-DEVELOPMENT-py2.7.egg/Exscript/protocols/Protocol.py", line 591, in login
with self._get_account(account) as account:
File "/usr/local/lib/python2.7/dist-packages/Exscript-DEVELOPMENT-py2.7.egg/Exscript/protocols/Protocol.py", line 567, in _get_account
account.__enter__()
AttributeError: 'str' object has no attribute '__enter__'

ps: I have tried also with paramiko, but it doesnt allow me to run multiple commands.

The login function expects an Exscript.Account object. Load your username and password into an Account and pass that in.

from Exscript.protocols import SSH2
from Exscript import Account

account = Account('user', 'password')
conn = SSH2()
conn.connect('192.168.86.12')
conn.login(account)
# ...
conn.close()

from Exscript.util.interact import read_login
from Exscript.protocols import SSH2
from Exscript import Host, Account

account1 = Account('uname','pwd')
conn = SSH2()
conn.connect('192.168.86.12')
conn.login(account1)
conn.execute('conf t')
conn.execute('no ip default-gateway')
conn.execute('ip default-gateway 192.168.68.10')

print "Response was:", repr(conn.response)
conn.send('exit\r')
conn.close()

I am new in this stuff and getting lot of hard time in my job,hope you guys help in this.

While login in multi nodes insert a certain commands to reconfirm the status of links and this should be document in a "txt" file or "log" file for confirmation I reached till below

from Exscript.protocols import SSH2    
from Exscript.util.file import get_hosts_from_file    
from Exscript import Account

accounts = [Account('myuser', 'mypassword')]    
conn = SSH2()          
hosts = get_hosts_from_file('myhosts.txt') 

def do_something(job, host, conn):
    conn.execute('sh int description | i PE')

start(hosts, accounts, do_something)    
conn.send('exit\r')    
conn.close()
