[paramiko] remote command info
Hi,
I'm a paramiko's newbie. I started with a simple ssh connection and command
execution like below:
import sys
import paramiko
client = paramiko.SSHClient()
client.load_system_host_keys()
ip = 'ip_server'
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(ip,port=22, username='my_user',password='**')
i, o, e = client.exec_command('ls -la')
print o.read()
client.close()
I don't understand the steps to exec multiple commands, like the example
below.
Es: if I exec before "cd /etc" command and after few time I want to exec a
"ls" command. What I do?
Sorry for my base English.
Regards.

Ok.
I find the example below:
i, o, e = client.exec_command('cd /etc')
i.write('ls\n')
i.flush()
I test it, but don't work.
Waht do you think about it?
You can get an interactive shell with invoke_shell(), but then you

I use it, but i don't like.
Thank's jim.

I want use the paramiko library for manage CISCO device (I test the code on
linux machine).
In my first test I wrote:
i, o, e = client.exec_command('command'+'command_1'+'command_2')
but the CISCO devices have a limited buffer and I can't put all command in a
only one time.
I tested that solution:
client.exec_command('cd /etc')
i, o, e = client.exec_command('ls')
print o.read()
but the output is only a ls print of my home directory and not of /etc
directory.
There is a method to implement my issue.
