Circumventing Deep Packet Inspection with Socat and rot13

Circumventing Deep Packet Inspection with Socat and rot13

I have a Linux virtual machine inside a customer's private network. For security, this VM is reachable only via VPN + Citrix + Windows + a Windows SSH client (eg PuTTY). I am tasked to ensure this Citrix design is secure, and users can not access their Linux VM's or other resources on the internal private network in any way outside of using Citrix.

The VM can access the internet. This task should be easy. The VM's internet gateway allows it to connect anywhere on the internet to TCP ports 80, 443, and 8090 only. Connecting to an internet bastion box on one of these ports works and I can send and receive clear text data using netcat. I plan to use good old SSH, listening on tcp/8090 on the bastion, with a reverse port forward configured to expose sshd on the VM to the public, to show their Citrix gateway can be circumvented.

Rejected by Deep Packet Inspection

I hit an immediate snag. The moment I try to establish an SSH or SSL connection over o

Async/Await - The challenges besides syntax - Cancellation

Async/Await - The challenges besides syntax - Cancellation

This is the second article in a series of articles around Rusts new async/await feature. The first article about interfaces can be found here.

In this part of the series we want to a look at a mechanism which behaves very different in Rust than in all other languages which feature async/await support. This mechanism is Cancellation.

Setting up rEFInd on Ubuntu 16.04 LTS for multi-boot purposes with secure boot enabled.

Deploying rEFInd on Ubuntu 16.04 LTS with secure boot enabled

Hello guys,

For these dual-booting Ubuntu 16.04 with an alternate operating system in UEFI boot mode, it may often be necessary to use a third-party boot manager such as rEFInd, as it's significantly superior to grub2's on UEFI-capable systems.

This write-up assumes that:

(a). The user is running a current Ubuntu 16.04LTS operating system installation (preferably on a dual-boot system)

Setting up Arch Linux LXC on ProxMox
1. Edit the mirror list located at /etc/pacman.d/mirrorlist and uncomment a preferred mirror (preferrably closest to you)
2. Initialize Pacman GPG Keys
- $> pacman-key --init
- $> pacman-key --populate archlinux
- $> pacman-key --refresh-keys -u --keyserver hkps.pool.sks-keyservers.net
*The use of the --keyserver flag is due to an error that currently occurs when using the default keyserver
3. Reinstall Arch keyring
- $> pacman -S archlinux-keyring
4. Install Yay (if desired)
- Create a user (you cannot run makepkg as root, you must be signed in as a user)

Linux Distribution Detection

Distribution Detection

I am working on adding support for building and distributing (via PyPI) Python Wheels with C Extensions to the Python wheel and pip packages. The discussion on Distutils-SIG continues, but I believe it is fairly certain that some effort to correctly identify Linux distributions will need to be made. I've begun efforts to add this support to wheel.

How you can help

If you have a Linux distribution or version of a listed distribution not in this gist, or one of the ones I have not directly verified, I could use the following:

  • The contents of /etc/os-release, if it exists

Experimental Docker Libnetwork DHCP Driver

The DHCP driver is intended for users to be able to integrate Docker IP address management with their existing IPAM strategies that use DHCP for dynamic address assignment. DHCP enables users to allocate addresses in an organized fashion that will prevent overlapping IP address assignment by associating a unique MAC address from the container eth0 Ethernet interface to an IP address as determined by the DHCP pools defined in the DHCP configuration.

This driver only provides the DHCP client functionality. It does not include a DHCP server. The default driver offers single-host IPAM or for distributed multi-host orchestrated IPAM see the libnetwork overlay driver.
