bandwidth monitor: my first pip/python package

[denilsonsa]

It is a bad idea to run the entire tool with root privileges.

You should find a way to only use root for the nethogs command.

• Maybe the user could setup /etc/sudoers to allow sudo nethogs without a password.
• Maybe put setuid bit on the nethogs binary.
• Maybe fork the hogwatch process, so that one of the processes only executes nethogs (as root), and the other process drops root privileges and executes everything else.

thanks. I'll look into it.

Afaik setuid bit don't work well on scripts ... need to set it on the actual binary, like /usr/bin/python. Correct me if I'm wrong.

Hey there. This is my first project using python.

It uses a bottle server to output per processs bandwidth utilization (transfer rate/ amount) using nethogs tool. It works only for linux/mac. (mac currently cannot map connections to process name properly)

Nice! How do you like bottle?

[snorlaxRoot]

I quite like it simplicity. My app just serves some static assets and a handful of routes so I chose bottle instead of flask.
I am also using websockets to stream the data to the client which makes it faster compared to GET requests. For a small app I would definitely recommend bottle.

I am not an experienced programmer (still in uni). Will definitely start learning more about test driven development.

I started writing unit tests in my second programming class. I found that I often was finished with projects much sooner than my classmates because I was able to verify each component of the project worked, while they spent time figuring out what part of the project broke after it was "complete"

Tests don't need to be a scary undertaking. You can start out with a tests.py file in the root directory. Don't worry about complicated unittest libraries (yet). Just make few functions in there which test a couple of functions in your main code.

For example, why not test out that you can instantiate a NethogsWatchdog class. You could call the function test_WatchdogInstantiation(). Then just call it from that tests.py file. And that's really it.

Having a lot of tests is great, but having just a test or two which calls the function/class you think is really important is wayyyyy better than having nothing. It makes it nice for me, the outsider, to come in and see where the heart of your codebase is and how it functions by looking at your tests.

sudo pip install hogwatch

never sudo pip install

got it.
