Python - 尝试使用 Paramiko 备份网络交换机，未收到预期输出 [重复]-解网

问：

在设备上使用 Paramiko exec_command 执行命令不起作用（1 个答案）

去年关闭。

我一直在尝试创建一个脚本，该脚本将从CSV文件备份我们的交换机。我正在使用 Paramiko 通过 SSH 连接到交换机并运行“show run”，但由于某种原因，我收到的唯一输出是交换机的名称。

import pandas
import paramiko

# Connection info
USERNAME = "username"
PW = "password"
PORT = 22
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

# Backup \ import location
DEST = "C:\\temp\\test\\"
CSV = DEST+"Switches.csv"

device_list = pandas.read_csv(CSV)
for index, row in device_list.iterrows():
    IP = row["IP"]
    floor = row["Floor"]
    side = row["Side"]
    formatted_ip = IP.replace(".", "_")
    filename = f"{formatted_ip}_{floor}{side}.txt"
    ssh.connect(hostname=IP, username=USERNAME, password=PW, port=PORT)
    stdin, stdout, stderr = ssh.exec_command('show running-config')
    stdin.close()
    output = stdout.readlines()
    errors = stderr.read()
    print(output)
    print(stderr.readlines())
    
    outfile = open(DEST + filename, "w")
    for char in output:
        outfile.write(char)
    ssh.close()
    outfile.close()

我收到的输出（也写入创建的文件）是SW-3A-48p-4>

我能够连接到交换机并运行“show run”。我期望获得整个交换机配置，但输出在第一行停止。

python ssh paramiko 切换

import pandas
import paramiko
from time import sleep

# Connection info
USERNAME = "username"
PW = "password"
PORT = 22
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) # I know this isn't recommended, I'll find a better solution for it.

# Backup \ import location
DEST = "C:\\temp\\test\\"
CSV = DEST + "Switches.csv"

device_list = pandas.read_csv(CSV)
for index, row in device_list.iterrows():
    IP = row["IP"]
    floor = row["Floor"]
    side = row["Side"]
    formatted_ip = IP.replace(".", "_")
    filename = f"{formatted_ip}_{floor}{side}.txt"

    ssh.connect(hostname=IP, username=USERNAME, password=PW, port=PORT)
    channel = ssh.invoke_shell()
    stdout = channel.makefile('r')
    channel.send('enable\r\n')
    sleep(1)
    channel.send('terminal length 0\r\n')
    sleep(1)
    channel.send('copy running-config startup-config\r\n')
    sleep(1)
    channel.send('y\r\n')
    sleep(10)
    channel.send('show running-config\r\n')
    sleep(2)

    data = channel.recv(5000)
    data = data.decode("utf8", "ignore")
    data = data.split('show running-config')
    data = data[1][:len(data) - 15]
    outfile = open(DEST + filename, "w")
    for char in data:
        outfile.write(char)
    ssh.close()
    outfile.close()

我确信有更好的方法可以做到这一点，但这目前有效。非常感谢所有帮助过的人。
