我在这个站点和其他多个位置搜索但我无法解决在一个命令后连接和维护ssh会话的问题.以下是我目前的代码:
#!/opt/local/bin/python
import os
import pexpect
import paramiko
import hashlib
import StringIO
while True:
cisco_cmd = raw_input("Enter cisco router cmd:")
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('192.168.221.235', username='nuts', password='cisco', timeout = 30)
stdin, stdout, stderr = ssh.exec_command(cisco_cmd)
print stdout.read()
ssh.close()
if cisco_cmd == 'exit': break
我可以运行多个命令,但是对于每个命令,都会创建一个新的ssh会话.
当我需要配置模式因为ssh session时,上面的程序不起作用
没有重复使用.非常感谢任何协助解决这个问题.
解决方法:
我使用Exscript而不是paramiko,我现在能够在IOS设备上获得持久会话.
#!/opt/local/bin/python
import hashlib
import Exscript
from Exscript.util.interact import read_login
from Exscript.protocols import SSH2
account = read_login() # Prompt the user for his name and password
conn = SSH2() # We choose to use SSH2
conn.connect('192.168.221.235') # Open the SSH connection
conn.login(account) # Authenticate on the remote host
conn.execute('conf t') # Execute the "uname -a" command
conn.execute('interface Serial1/0')
conn.execute('ip address 114.168.221.202 255.255.255.0')
conn.execute('no shutdown')
conn.execute('end')
conn.execute('sh run int Serial1/0')
print conn.response
conn.execute('show ip route')
print conn.response
conn.send('exit\r') # Send the "exit" command
conn.close() # Wait for the connection to close
