On daily basis I deploy, maintain and support one of the largest CDNs in the world. I enjoy working on projects involving automation, monitoring, analysing and tweaking *nix system performance, troubleshooting networks, tinkering with virtualisation, etc.

Publishing the pcap file would be much more useful. You can't filter through that you shared effectively.

comment Why is my partition claiming to be out of space?
The way you keep referring to file systems without identifying them precisely and mixing folders with mount points makes your question an excercise of finding out what you actually meant. Root fs has ~4GB of free space and resides on /dev/sda5. From the information you provided, 'OS' is not a mere folder within an FS but a mount point for the /dev/sda2 partition which has over 70GB of free space. What are you referring to as "your Ubuntu partition"? It looks like you're confusing folders, mount points and partitions.

comment How to learn linux?
There are some good suggestions here but I can't agree with the "avoid books" comment which as it is worded is plain wrong. Yes, the UI applications and environment change very often but it's not about learning to use applications, but the basics and those are fairly stable and if you grasp them, learning to use applications isn't much of an issue.

You don't need localtunnel :) What the netstat output shows you is that your HTTP server is only accepting connections from your local machine. It looks like you need to change SERVER_NAME variable in Flask's configuration.

comment How can I open specific ports for my Apache server?
Is this about allowing incoming connections to specific ports Apache is already listening to or are you asking about configuring Apache to listen on specific ports? Please provide information when asking questions - in its current state your question is too vague.

This is why I suggested looking at the Flask's docs to configure it to listen on all addresses. Have you looked at it? Allowing it through the firewall alone won't fix it.

Capture the traffic and make the pcap file available to download from somewhere as per my previous comment :)

comment Which Folders To Include In backup?
Also, in addition to what the answer psny linked to, it wouldn't hurt to create a back up of the whole /etc/ directory which stores system wide settings. If you've made some changes there, it would be helpful to have an archive to get those changes from.
