• IPSec is just an encrypted IP packet
• Meaning everything after IP header is encrypted
• Well, there is also AH header between IP header and encrypted contents
• The AH header specifies how the content is encrypted
• If AH matches on client and receiver, the packet is passed to decryption
• What happens when the packet is decrypted depends on packet handler on receiving side

Several files contain instructions for packing a software for Debian. The all should be placed in debian/ subdirectory. If upstream sources already come with debian/ dir, they are said to be debianized or native. If there is no such dir, then it is added by diff (.diff.gz) or a separate archive (.debian.tar.gz).

The source code with debian/ dir should be compressed and pushed to Debian to build.

native debian package

• upstream source comes in .orig.tar.gz

I need to trace Flask request what is hanging. I try to use OpenTracing and friends.

• Zipkin

server

podman run -d -p 127.0.0.1:9411:9411 openzipkin/zipkin

clients

• import opentracing from https://github.com/opentracing/opentracing-python doesn't send anything to servers (and to http://127.0.0.1:9411/zipkin in particular). Weird. Need to find a wrapper for it. Maybe I've missed something.

• OBS organizes everything into Projects.
• Every user has default project, mine is home:abitrolly.
• To build a package, you need to select Repository where this package will be stored.
• Repository is Distribution specific.
• OBS nows nothing about Distribution, it is just an ordinary top level Project.
• Repository is identified by Project/type string, like Debian:8.0/standard.

• Package is just a name inside a Project. It needs files to be built.
• Use osc checkout to get package files.

Security is not a state. It is a practice, exercise.
The same way your body needs physical exercise to
stay fit and feel great, the same way your online
habits should follow the good security practice and
learning it. You don't need to be a sportsman or
addicted to diets to feel well, and you don't need
to be the hacker or researcher to feel secured.

The security of people at whole is the security of
every human in person.

s/you can/you should/ and here is what you need to do.

You should create at least one workflow as a .yaml/.yml file in .github/workflows/ dir.

Each workflow contains on trigger and jobs, each job contains steps.
