[英]Run multiple commands in different SSH servers in parallel using Python Paramiko
[英]Running Multiple SSH Commands Using Paramiko in Python 3.4.3
我正在嘗試在一個盒子上運行多個命令,但只有第一個命令成功。 這似乎與fork有關,但我無法弄清楚如何解決這個問題。 您的幫助或指導將不勝感激。
import paramiko
#Made in python 3.4.3
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('xxx.xx.xx.xx', port=22, username='domain\myusername', password='mypassword')
stdin, stdout, stderr = ssh.exec_command('vol status -f') #this being the first command works fine
output = stdout.readlines()
print ("\n".join(output))
stdin, stdout, stderr = ssh.exec_command('disk show -n')
output1 = stdout.readlines()
print ("\n".join(output1))
#stdin, stdout, stderr = ssh.exec_command('vol status -s')
#stdin, stdout, stderr = ssh.exec_command('df -Ag')
ssh.close()
input("Press <Enter> to exit ")
Traceback (most recent call last):

如果您認為fork是問題,請嘗試使用Transport類的atfork()
方法 。
