A comment on lobste.rs, in a thread about DNS gave a great idea and thought a robust tool like that might come in handy!

brew install dstp

go install github.com/ycd/dstp/cmd/dstp@latest

You can install dstp using one of these methods:

1. Using nix-shell or nix shell (recommended for trying it out):

nix shell nixpkgs#dstp

2. Adding to your NixOS configuration (system-wide installation):

# configuration.nix or home-manager configuration
{
  # ...
  environment.systemPackages = with pkgs; [
    dstp
  ];
}

3. Or using nix profile (for individual user installation):

nix profile install nixpkgs#dstp

git clone https://aur.archlinux.org/dstp.git
cd dstp
makepkg -sri

Binary downloads of example are available from the releases section on GitHub for 64-bit Windows, macOS, and Linux targets. They contain the compiled executable.

0. Verify that you have Go 1.17+ installed (The source code uses ( //go:build ) conditional compilation directives that is introduced in Go 1.17.)

   $ go version
   

   If go is not installed, follow instructions on the Go website.

1. Clone this repository

   $ git clone https://github.com/ycd/dstp 
   $ cd dstp
   

2. Build and install

   Unix/Linux

   # May require you to use sudo
   $ go build cmd/dstp/dstp.go
   $ cp dstp /usr/local/bin/dstp
   

   Mac/BSD

   # May require you to use sudo
   $ make
   $ cp dstp /usr/local/bin/dstp

The command dstp may collide with docker stopcommand if you are using the docker plugin with oh-my-zsh.

To fix this, you can add the following command at the end of your .zshrc file:

unalias dstp
