SSH to cRIO

Hi Everyone,
Is it possible to connect to the cRIO through SSH? I know that on the Windows side it has a NetConsole that lets you communicate with the cRIO through the terminal. Can you connect to it in a similar manner with SSH and Terminal (or Prompt on iOS)? If anyone knows how to do that, I would really appreciate the help.
Thanks!

Re: SSH to cRIO

netconsole sends/receives on UDP port 6666. You just need a program that supports that, such as netcat.

Re: SSH to cRIO

What are you trying to do? FTP and netconsole should be able to handle most tasks...

Re: SSH to cRIO

I want to be able to monitor the console without using the netconsole app, essentially.

Perhaps if you share your reason for not using the application provided we can suggest possible solutions for your use-case.

Re: SSH to cRIO

FileZilla is always an option if your wanting to transfer files and stuff to your cRio or if you want to transfer a .out file to the ni-rt folder if your handy dandy button in WindRiver isn't uploading code for some reason.

Re: SSH to cRIO

I use a modified version of Dustin Spicuzza's cross-platform netconsole:

Code:

#!/usr/bin/env python2



import socket

import select

from sys import stdout as stdout



UDP_PORT=6666



sock = socket.socket( socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP )



sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

sock.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)

sock.bind( ('',UDP_PORT) )

sock.setblocking(0)



while True:

    result = select.select( [sock], [], [] )

    msg = result[0][0].recv( 8196 )

    for c in msg:

        stdout.write(c)

My reason? My main computer is a mac. If I didn't have to fire up windows just to watch the netconsole, I'd be happy.

Have you tried netcat or ncb? How about the python above?
