Not able to copy tftp to device using python

Please review below code, not able to copy config from device to tftp and vice versa

import paramiko
ssh = paramiko.SSHClient()

ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

ssh.connect('192.168.1.12', port=22, username='cisco', password='cisco')

stdin, stdout, stderr = ssh.exec_command('copy tftp: flash: ')

stdin.write('192.168.1.10')

stdin.write('\n')

stdin.flush()

stdin.write('demotesting')
stdin.write('\n')
stdin.flush()

stdin.write('dest_demo')
stdin.write('\n')

output = stdout.readlines()
print '\n'.join(output)
ssh.close()

Why not just put the whole copy command on one line, instead of trying to write special characters?

stdin, stdout, stderr = ssh.exec_command("copy tftp://192.168.1.10/folder/file.ext flash:")

Open in new window

Also, have you trusted 192.168.1.10's SSH key on the remote device first?

Are you using "login local" authentication on the VTY lines, or are you using aaa authentication?

jack jones

ASKER

we are using login local for authentication

Craig Beck

Try using aaa instead. I'm sure I remember a bug which affects autocommands when using login local.
