About: I created a cheatsheet for my own reference as I'm learning about Docker. I found myself often looking up the same commands multiple times and thought to write it all down. Hopefully this helps others!
docker ps -a or docker container list - List all containers
docker ps -aq - List all container ID's
docker stop or docker rmdocker image list - List all docker images
| Using GNS3 2.2.26 on a Kubuntu Linux host, I discovered that the Network Automation appliance (which is an extremely slimmed-down Docker container of Ubuntu 20.04.3 LTS) does not allow SSH out of the gate. | |
| To fix this, I did the following: | |
| - Ensure the device is reachable (assign a static IP) | |
| - Install SSH (apt install openssh-client openssh-server) | |
| - Edit the /etc/ssh/sshd_config file and | |
| 1) un-comment the line 'ListenAddress 0.0.0.0' | |
| 2) Search for "PermitRootLogin" and change from "PermitRootLogin prohibit-password" to "PermitRootLogin yes" | |
| a. CAVEAT - This is NOT SECURE, obviously, but given this is a sandboxed/lab environment with no critical services running, it should be OK. This should *never* be done in a production environment, ever ever ever ever ever!!! |
| This gist contains instructions on how to install NetBox on a vanilla installation of Ubuntu server. The official documentation has some steps missing, and some steps out of order. | |
| OS: Windows 10 Pro x64 | |
| Software: VMWare Workstation Pro 16 | |
| VM OS: Ubuntu Server 20.04.2 LTS | |
| # DISCLAIMER | |
| This installation is *not* secure, intentionally. I simply wanted to get it running and write a guide in my own flavor. I found a few issues in the official documentation that are addressed in this guide and will be fed back to the documentation maintainers. | |
| # Install SSH & Postgres | |
| sudo apt-get install openssh-server postgresql libpq-dev -y |

| I found some of the steps did not work for me on Ubuntu 20.04, so I made my own gist below. This has been tested on both my laptop and desktop running 20.04, both fresh/recent installs. | |
| -------------------------------------------------------- | |
| To install Chirp on Ubuntu Linux 20.04 as of 19 NOV 2020 | |
| -------------------------------------------------------- | |
| 1) Edit the apt sources to change "Focal" to "Xenial" | |
| a. sudo nano /etc/apt/sources.list.d/dansmith-ubuntu-chirp-snapshots-focal.list | |
| b. Change "Focal" to "xenial" |
| Desired layout: | |
| No color - Base layer - QWERTY | |
| Red - Modifier layer - !@#$%^&*() symbols, modifiers | |
| Green - Media layer - media controls | |
| Blue - Gaming layer - layout modified for League of Legends, and other games | |
| Purple - LED Layer - layout for controlling underglow & RGB | |
| Orange - Passwords layer | |
| White - Cisco layer - momentary toggle this layer, where certain keys will have certain command macros bound (sh ip int brief, sh log | ex SSH2, sh int desc, sh ip bgp summ, sh ip eigrp neigh, etc) | |
| Yellow - Linux layer - VIM keymappings, other keystrokes and combinations that are specific to Linux (Ubuntu w/ Unity, Arch) | |
| sudo nano /usr/share/wireshark/init.lua | |
| change run_user_scripts_when_superuser = false to | |
| change run_user_scripts_when_superuser = true | |
| and then change the if condition | |
| if running_superuser then to | |
| if not running_superuser then |
