IP Tables (iptables) Cheat Sheet

IPTables is the Firewall service that is available in a lot of different Linux Distributions. While modifiying it might seem daunting at first, this Cheat Sheet should be able to show you just how easy it is to use and how quickly you can be on your way mucking around with your firewall.

Resources

The following list is a great set of documentation for iptables. I used them to compile this documentation.

1. Download docker-compose.yml to dir named sentry
2. Change SENTRY_SECRET_KEY to random 32 char string
3. Run docker-compose up -d
4. Run docker-compose exec sentry sentry upgrade to setup database and create admin user
5. (Optional) Run docker-compose exec sentry pip install sentry-slack if you want slack plugin, it can be done later
6. Run docker-compose restart sentry
7. Sentry is now running on public port 9000

Problem: When linking to the raw version of a gist, the link changes with each revision.

Solution:

To return the first file from a gist: https://gist.github.com/[gist_user]/[gist_id]/raw/

• Example: https://gist.github.com/atenni/5604522/raw/
• Works even when you change the filename.

To get a file from multi–file gist: https://gist.github.com/[gist_user]/[gist_id]/raw/[file_name]

If you want to clone an svn repository with git-svn but don't want it to push all the existing branches, here's what you should do.

* Clone with git-svn using the -T parameter to define your trunk path inside the svnrepo, at the same time instructing it to clone only the trunk:
  
  git svn clone -T trunk http://example.com/PROJECT

* If instead of cloning trunk you just want to clone a certain branch, do the same thing but change the path given to -T:

  git svn clone -T branches/somefeature http://example.com/PROJECT

# Docker networking is messy and undocumented. Docker will create IP addresses and iptables at random times.
# This can be limited by using totally static IP addresses for network interfaces and avoiding the default network bridge.

# /etc/default/docker
# DOCKER_OPTS="--iptables=false --ipv6 --bip 172.16.0.1/16 --fixed-cidr 172.16.0.0/16 --fixed-cidr-v6 2a01:9000::/68"
# --bip is the host IP address of the docker0 interface
# --fixed-cidr is the CIDR subnet allocated to the docker0 interface (default network bridge)
# --fixed-cidr-v6 is the IPv6 CIDR allocated to docker0

# for IPv6 split your /64 delegated subnet into /68 subnets and allocate them to each docker-compose.yml subnet:

'Twas the night before Christmas, when all through the racks
Not a server was alerting, not even Compaqs.
The backups were written to tapes with care
In hopes that later the data would be there.

The machines were nestled all snug in their sleds
Whilst visions of vengeance danced in their heads;
And oncall in his three-wolf and I in my rack.
Had just settled down for some syn and some ack.
