Assuming you received the certificate in DER form, saved to cert.der
:
openssl x509 -inform der -in cert.der -out chain.pem
Append the content of

1) Filter Table
Filter is default table for iptables. So, if you don’t define you own table, you’ll be using filter table. Iptables’s filter table has the following built-in chains.
This may work with other Macbook Pro models that have an Intel GPU and a NVidia one, but I only have proof that this works on a MacBook Pro Mid 2014 (MacBookPro11,3) with Ubuntu 18.04.
If you want to be sure about which model you have, run sudo dmidecode -t system
in the Terminal and you will see the information about the system including the serial number and product name (MacBookPro11,3 in my case).
I'm assuming you have installed the NVidia propietary drivers, which can be installed from the application "Software & Updates" in the tab "Additional Drivers".
Steps to use the Intel GPU:
lspci |grep VGA
and check that only one line mentioning "NVIDIA" is printed. This is to be sure that you are required to do the following steps. If two lines appear, and one of those mentions "Intel", then you probably do not need to activate the GPU but only select it as the main GPU (jump to the step where you have to "Open nvidia-settings

I was trying to get the Arduino IDE to work inside a Docker container on OS X. I was able to get the IDE working (see Getting X11 GUI applications to work on OS X with Docker), but I could not figure out how to make the USB port for the Arduino visible.
I first tried to directly map hardware serial port into the Docker container, doing something like this:
The IMAP protocol workflow consists of the following steps,
The interactions consists of strings of lines, i.e. string terminated by a carriage return and a line feed (CRLF or \r\n). Interactions can be both commands (sent by clients) and data (sent by clients and servers). Both the client and the server strictly interact using lines or known length octet streams (8-bit characters) followed by a line.
####Client
An IMAP client issues commands to the server in a CRLF terminated string. The syntax of a command includes a tag, followed by the command and parameters. A tag is an alphanumeric identifier and each client command has a different tag for that session. A tag could be something like but not limited to A1, A2 etc.
When running virtual machines under a Linux host system for testing web apps in various browsers (e.g. Internet Explorer), I found it rather tedious having to continually tweak the hosts file within each VM for the purpose of adding entries pointing back to the host machine's development web server address.
Instead the steps below will setup Dnsmasq on a Ubuntu 16.04LTS, 14.04LTS or 12.04LTS host machine for the purpose of serving both it's own DNS queries and that of virtual machine guests. Dnsmasq will parse the /etc/hosts
file on your host machine where we will keep a single set of DNS entires to our test web application(s).
## Trafik Multi Network Deployment | |
1. Create Traefik network | |
` # docker network create --driver=bridge --attachable --internal=false traefik ` | |
2. Edit `traefik2/docker-compose.yml` | |
- Change ACME email | |
- Change --providers.docker.network=traefik value if you created different network then `traefik` |
