picosnitch VS bcc

Yep, and from my experience too (made a tool that monitors network traffic with eBPF [1]) in addition to those issues there is also a sizable latency hit.

Similar to bandwhich, I recently created a snap of my own bandwidth monitor, picosnitch [1]. However I was only able to get it working with classic confinement (so it can't be published on the store) due to there being no snap interfaces for fanotify or BPF kfuncs.

I already packaged it for nearly every distro, but unfortunately most don't have dash [2] in their repos so the user needs to install it separately, and I was hoping that snap would be an easier solution for that.

I created picosnitch which can do this

If you're still having this issue, you can try picosnitch (I recently made it available in copr).

You can use picosnitch for this, I'm the developer and this is exactly the use case I had in mind when designing it (24/7 monitoring of traffic on a per executable basis, primarily in containerized environments).

I wrote picosnitch [1] which has the same notification and bandwidth monitoring features, however it doesn't block traffic for a couple reasons: avoiding scope creep so I can focus on more reliable detection and do things like hash every executable, which makes it harder to block traffic in a timely fashion.

I also wrote a program (picosnitch) which is newer than that list and has a bunch of features none of those other tools have, in case you're interested in checking it out!

which basically says launchpad builds the package directly from that repository, which states: This repository is an import of the Git repository at https://github.com/elesiuta/picosnitch.git.

picosnitch - monitors and hashes programs that connect to the internet, and can check them with VirusTotal.

For Linux, I created picosnitch which does exactly what you're looking for.

But wait, there's more! Enter the BCC toolkit and library, your trusty sidekick in simplifying the arcane art of writing eBPF applications. With BCC by your side, you'll be wielding eBPF like a seasoned pro in no time.

Nice - I normally use [bash-readline](https://github.com/iovisor/bcc/blob/master/tools/bashreadlin...) when coworking/co-inhabiting a server or training someone.

One of the big wins is not so much “build and run your own stuff” but there are very nice low-cost (in terms of compute) performance utilities built on eBPF

https://github.com/iovisor/bcc

There are so many utilities in that list; there’s a diagram midway down the readme which tries to help show their uses. bcc-tools should be available in any distro.

Also, Brendan Gregg does a ton of performance stuff that is worth knowing about if you check out his other work. Not eBPF only. Flame graphs are useful.

In this article, we'll build a basic version of an HTTPS sniffer, inspired by bcc-sslsniff.py, but we'll use Rust and Aya. We're going to demonstrate the capabilities of uprobes by employing uprobe and uretprobe along with familiar maps like PerCpuArray, HashMap, and PerEventArray. This will be a straightforward example to help us explore how uprobes function.

As xpd program I am using the BCC example xdp_redirect_map.py in skb mode as my NIC does not support native mode, attaching the program to veth2 and a dummy function to veth3
