• Non-servers can talk to servers, but not each other
• Kind of like Client Isolation on some WiFi controllers

Rules

# Allow only IPv4, IPv4 ARP, and IPv6 Ethernet frames. Typical default
drop
not ethertype ipv4
and not ethertype arp

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
