netmiko-mhrt 1.0.3

a forked version of netmiko_multihop

netmiko_multihop is an out of tree netmiko monkeypatch which adds multihop capability. Currently following platforms are supported as intermediate hop:

• linux

• cisco_nxos

• cisco_ios

Other platforms can be added easily if required.

Installation

Install the netmiko_multihop package by running:

pip3 install netmiko-mhrt

Usage

import  netmiko_multihop
from netmiko import ConnectHandler


jumphost1 = {
    'device_type': 'linux',
    'ip': <ip_jumphost1>,
    'username': <ssh_username_jumphost1>,
    'password': <ssh_password_jumphost1>,
    'port': 22,
}

jumphost2 = {
    'device_type': 'linux',
    'ip': <ip_jumphost2>,
    'username': <ssh_username_jumphost2>,
    'password': <ssh_password_jumphost2>,
    'port': 22,
}

target1 = {
    'device_type': 'cisco_nxos',
    'ip': <ip_target1>,
    'username': <ssh_username_target1>,,
    'password': <ssh_password_target1>,
    'port': 22,
}

target2 = {
    'device_type': 'cisco_ios',
    'ip': <ip_target2>,
    'username': <ssh_username_target2>,
    'password': <ssh_password_target2>,
    'port': 22,
}

# If the next hop is reachable via vrf on the current hop, add the vrf parameter to the destination configuration.
# Eg.: Target1 is reachable via vrf mgmt from target2.
#      You want to jump from target1 to target2.
#      Add the parameter vrf='mgmt' to target2 configuration before you jump from target1 to target2.

ssh = ConnectHandler(**jumphost1)
# now we are on jumphost1
# this is where the magic starts. as jump_to returns the object instance we can jump multiple hops at once

ssh.jump_to(**jumphost2).jump_to(**target1)
# now we are on target1
print(ssh.send_command("show inventory"))
# lets get back a single jump
ssh.jump_back()
# now we are on jumphost2
ssh.jump_to(**target2)
# now we are on target2
print(ssh.send_command("show inventory"))
ssh.jump_back()

Patch

In some cases network device may have a warning banner following the login banner, and need user input (yes or a simple enter) to continue. This patch pads in an “enter” command in the channel when “continue:” or “#” is detected during jump_to() process.
