How to run sudo with paramiko?

What I've tried:

1. invoke_shell() then channel.send su then send the password resulted in not being root
2. invoke_shell() then channel.exec_command resulted in Channel Closed error
3. _transport.open_session() then channel.exec_command resulted in not being in root
4. invoke_shell() then write to the stdin and flush it resulted in not being in root

To my mind it would be much easier and secure to create a script which has sudoer rights.

For example, add this to sudoers:

myuser  ALL=NOPASSWD:/home/myuser/somescript.sh

Python Remote SSH with Paramiko

I am using Paramiko to do some remote ssh work and could not figure out how to change directories and execute a script with the SSHClient.execute_command() function. I finally figured out that .execute_command() is basically a single session, so doing a .execute_command('cd scripts') and then executing the script with another .execute_command() reverts back to your default directory. The alternatives are to send all the commands at once separated by a ; .execute_command('cd scripts; ./myscript.sh'), or to use the .interactive() shell support. Since I only needed to fire off this script I used the first solution.

 意思就是execute_command() 他是a single session，每次执行完后都要回到缺省目录。所以可以 .execute_command('cd  /var; pwd')

或者使用aa = ssh.invoke_shell()
aa.send('cd /var\n')
