# get_isis.py

SSH to Juniper, Cisco IOS, and Cisco IOS-XR routers
and get a list of interfaces with active ISIS adjacencies.
Display these interfaces in a table with the currently
reported interface traffic and IPv4 ISIS metric.

REQUIRES : netmiko, paramiko, prettytable

The default behavior is currently to run with no arguments
and prompt for the following:
  Hostname/IP, Device OS, Username, Password 

Also, get_isis can be used to connect via local SOCKS proxy:

1. Line 65 in modules.py specifies an alternate ssh config file ~/.ssh/proxy.config by default
2. Create a file in your ~/.ssh/proxy.config as follows:
      echo 'ProxyCommand proxy_cheater %h' > ~/.ssh/proxy.config
3. Create a bash script to fix the IP/port for netcat:
      vim proxy_cheater
      #!/bin/bash
      ADDR="$1"
      HOST=${ADDR%:*}  # get the part before the colon
      PORT=${ADDR##*:}  # get the part after the colon
      /bin/nc -x 127.0.0.1:1080 $HOST $PORT
   (Make it executable and put it in your PATH)
4. Start a local SOCKS proxy connection on 127.0.0.1:1080


If the following Error is seen connecting to Cisco IOS devices:
	paramiko.ssh_exception.SSHException: Error reading SSH protocol banner

 	Edit transport.py near line 487 (something like /usr/local/lib/python2.7/dist-packages/paramiko/transport.py)
 		# synchronous, wait for a result
        self.completion_event = event = threading.Event()
        # delay starting thread for SSH proxies
        event.wait(3)  # MONKEY_PATCH added wait
        self.start()
        while True:
