This is just some quick data from the CF browser isolation beta. If you inspect the isolated webpage, there's a debug-sidebar you can add a show class to to make visible. From there, you can run a trace and get some info about the machines these VMs are on. These are the stubs of the metadata elements of two random traces I made.

P.S. no exploits found yet ;)

Introduction

I often find myself ssh'ing into my servers and checking my systemd service logs with $ journalctl -f -u {name}.service. One day I got tired of this and wanted all of my important logs in once place (Amazon AWS Cloudwatch). To my dismay, there weren't any real good tutorials on how to do so. So, voilà.

Steps

Overall, it's a fairly simple process consisting of the following few steps.

1. Modify the service file

Open the service file with $ sudo vi /lib/systemd/system/{name}.service

Modify the [Service] section:

How to recover lost Python source code if it's still resident in-memory

I screwed up using git ("git checkout --" on the wrong file) and managed to delete the code I had just written... but it was still running in a process in a docker container. Here's how I got it back, using https://pypi.python.org/pypi/pyrasite/ and https://pypi.python.org/pypi/uncompyle6

Attach a shell to the docker container

Install GDB (needed by pyrasite)

apt-get update && apt-get install gdb
