Python Exscript - JunOS

Question

我試圖運行腳本來顯示所有配置，並將它們寫入juniper和CISCO路由器的文件中。 到目前爲止，CISCO腳本的工作原理與Juniper路由器一樣。

for ii in JUNIPER: 
    print ii 
    cmd2 = 'show configuration | display set' 
    conn.connect(ii) 
    conn.login(account1) 
    conn.execute(cmd2) 
    print conn.response 
    #filerouter = open(ii, "w") 
    #filerouter.write(conn.response) 
    #filerouter.close() 

獲得設備列表查詢後，我跑這一點，但它卡住彷彿有緩衝的限制... -

如果我試圖做一個不同的命令：
("show configuration | display set | match destination ")
- 我得到寫在文件或屏幕上的輸出。

=========== ====問題 - 如何讓腳本運行，並提供命令的輸出：show configuration | display set第二PIC顯示錯誤我得到但是如果我將命令更改爲：show configuration | display set | match description，我會收到請求的信息。我是否缺少在模塊中添加一些內容，以便exscript/python避免超時？

Answer 1

默認情況下，JunOS爲任何命令返回的冗長輸出分頁。可能發生的情況是，您要連接到的Juniper設備正在對show configuration | display set命令的輸出進行分頁，並且Exscript正在超時，因爲設備正在等待用戶輸入以繼續命令輸出的分頁，而不是返回提示Exscript可以識別。

我會做以下修改：

for ii in JUNIPER: 
    print ii 
    cmd2 = 'show configuration | display set | no-more' 
    conn.connect(ii) 
    conn.login(account1) 
    conn.execute(cmd2) 
    print conn.response 

這將禁用輸出分頁特定命令，並應立即返回提示，允許Exscript到輸出返還給您。良好的措施我還添加了一個回車我的命令爲好，即：

cmd2 = 'show configuration | display set | no-more\r' 

但上面做的用處是值得商榷的，因爲如果我沒有記錯的​​方法應該爲你反正做這個。

對於使用python處理的Junos的設備，我會建議你使用PyEZ - https://github.com/Juniper/py-junos-eznc

from jnpr.junos import Device 
from lxml import etree 

dev = Device('hostname', user='username', password='Password123') 
dev.open() 

cnf = dev.rpc.get_config() # similar to 'show configuration | no-more' on cli 
print (etree.tounicode(cnf)) 

dev.close() 

Answer 3

我用用PyEZ這個腳本JSON使用倍數的IP地址。

from jnpr.junos import Device 
from lxml import etree 
import json 


config_file = open('config.json') 
config = json.load(config_file) 
config_file.close() 


for host in config['ip']: 

    dev = Device(host=host, user=config['username'], 
    password=config['password'], port=22) 
    dev.open() 
    data = dev.rpc.get_config(options={'format':'set'}) 
    file_name = dev.facts['fqdn'] 
    print(etree.tostring(data)) 
    dev.close() 

    f = open(file_name + '.txt', 'w') 
    f.write(etree.tostring(data)) 
    f.close() 

JSON文件看起來像：

{ 
    "username": "user", 
    "password": "password", 
    "ip": [ 
      "10.255.6.100", 
      "10.255.6.101", 
      "10.255.6.102", 
      "10.255.6.103", 
      "10.255.6.104" 
      ] 
}
