paramiko

I launch a shell script from a remote Linux machine using paramiko. The shell script is launched and execute a command make -j8. However the exec_command returns before the completion of the make. If I launch the script on the local machine it executes correctly. Could someone explain me this behaviour ? You need to wait for application to finish, exec_command isn't a blocking call. print now(), "before call" stdin, stdout, sterr = ssh.exec_command("sleep(10)") print now(), "after call" channel = stdout.channel print now(), "before status" status = channel.recv_exit_status() print now(),

一：简介 paramiko是用python语言写的一个模块，遵循SSH2协议，支持以加密和认证的方式，进行远程服务器的连接。 由于使用的是python这样的能够跨平台运行的语言，所以所有python支持的平台，如Linux, Solaris, BSD, MacOS X, Windows等，paramiko都可以支持，因此，如果需要使用SSH从一个平台连接到另外一个平台，进行一系列的操作时，paramiko是最佳工具之一。 举个常见的例子，现有这样的需求：需要使用windows客户端，远程连接到Linux服务器，查看上面的日志状态，大家通常使用的方法会是： 1：用telnet 2：用PUTTY 3：用WinSCP 4：用XManager等… 那现在如果需求又增加一条，要从服务器上下载文件，该怎么办？那常用的办法可能会是： 1：Linux上安装FTP并配置 2：Linux上安装Sambe并配置… 大家会发现，常见的解决方法都会需要对远程服务器必要的配置，如果远程服务器只有一两台还好说，如果有N台，还需要逐台进行配置，或者需要使用代码进行以上操作时，上面的办法就不太方便了。 使用paramiko可以很好的解决以上问题，比起前面的方法，它仅需要在本地上安装相应的软件（python以及PyCrypto），对远程服务器没有配置要求，对于连接多台服务器，进行复杂的连接操作特别有帮助。 二：安装

client = paramiko.SSHClient() stdin, stdout, stderr = client.exec_command(command) Is there any way to get the command return code? It's hard to parse all stdout/stderr and know whether the command finished successfully or not. JanC SSHClient is a simple wrapper class around the more lower-level functionality in Paramiko. The API documentation lists a recv_exit_status() method on the Channel class. A very simple demonstration script: $ cat sshtest.py import paramiko import getpass pw = getpass.getpass() client = paramiko.SSHClient() client.set_missing_host_key_policy(paramiko.WarningPolicy())

I'm working on a script (python 2.7) that is wotking with a remote device running Cisco IOS, so I need to execute a lot of commands through ssh. Few commands have no output and some of them have, and I want to recieve the output. It goes something like this: import paramiko ssh=paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect(self._ip, port=22, username=username, password=password stdin, stdout, stderr = ssh.exec_command('command with no output') stdin, stdout, stderr = ssh.exec_command('command with no output') stdin, stdout, stderr = ssh.exec_command

I am trying to ssh a server using Paramiko and execute a command. But the paramiko.exec_command() returns with an error.Why is this happening? This is my Python script: import paramiko ssh = paramiko.SSHClient() ssh.load_system_host_keys() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect('10.126.141.132', username='usrm', password='passwd') stdin, stdout, stderr = ssh.exec_command("show chassis") print(stdout.readlines()) ssh.close() When executed it returns with this message: ['Extra params found in CLI, this is not supported, exiting the CLI session:\n'] I am using
