Hello I'm looking for a experienced network developer who has experience working with applications of bandwidth usage in linux like Snort, Bandwidthd, etherape, ntop, mrtg, etc. I would like to know which is the main traffic of my network http, vpn,, voip, etc. I would like to see it graphically. I've attached a file where you can see what I would like to reach. Let me give you more detail: I would configure port 1 and port 5 of mikrotik router as a switch (any ip configuration). I would connect ethernet cable from router 1 in port 1 and in port 5 ethernet cable of router 2 would be connected. All traffic between router 1 and router 2 would go through mikrotik. I wont setup ip address on port 1 and 5 because I dont want to change configuration of my network. In port 3 of mikrotik I would mirror traffic that goes through mikrotik. In port 3 of mikrotik I would connect a linux pc where a bandwidth usage linux application would be running and measuring traffic. In summary, I need a network developer who has experience working with applications of bandwidth usage in linux. He/she should recommend me a bandwidth usage monitor for linux, setup and configure it on linux pc. In case, you have a better proposal for monitor bandwidth usage, I would be happy to listen to your ideas. By the way, Please avoid copy and paste long curriculum, I prefer reading proposal, ideas, suggestions, etc. I pay more attention this kind of proposal to go next step "Interview" Thank you so much for your attention Robert

The script needs to run continuously as a cron job. I need the script and the instructions to install the same.
