Latest Release GoDoc Build Status

The SSH directory ✨

Gif

With Wishlist you can have a single entry point for multiple SSH endpoints, whether they are Wish apps or not.

As a server, it can be used to start multiple SSH apps within a single package and list them over SSH. You can list apps provided elsewhere, too.

You can also use the wishlist command to list and connect to servers in your ~/.ssh/config or in a YAML configuration file.

Installation

Use your fave package manager:

# macOS or Linux
brew install charmbracelet/tap/wishlist

# Arch Linux (btw)
yay -S wishlist-bin
# or
yay -S wishlist

# Windows (with winget)
winget install wishlist

# Windows (with Scoop)
scoop bucket add charm https://github.com/charmbracelet/scoop-bucket.git
scoop install wishlist

# Nix
nix-env -iA nixpkgs.wishlist

# Debian/Ubuntu
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://repo.charm.sh/apt/gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/charm.gpg
echo "deb [signed-by=/etc/apt/keyrings/charm.gpg] https://repo.charm.sh/apt/ * *" | sudo tee /etc/apt/sources.list.d/charm.list
sudo apt update && sudo apt install wishlist

# Fedora/RHEL
echo '[charm]
name=Charm
baseurl=https://repo.charm.sh/yum/
enabled=1
gpgcheck=1
gpgkey=https://repo.charm.sh/yum/gpg.key' | sudo tee /etc/yum.repos.d/charm.repo
sudo yum install wishlist

Or download a pre-compiled binary or package from the releases page.

Or just build it yourself (requires Go 1.19+):

git clone https://github.com/charmbracelet/wishlist.git
cd wishlist
go build ./cmd/wishlist/

Usage

CLI

Remote

If you just want a directory of existing servers, you can use the wishlist CLI and a YAML config file. You can also just run it without any arguments to list the servers in your ~/.ssh/config. To start wishlist in server mode, you'll need to use the serve subcommand:

wishlist serve

Check the example config file file as well as wishlist server --help for details.

Local

If you want to explore your ~/.ssh/config, you can run wishlist in local mode with:

wishlist

Note that not all options are supported at this moment. Check the commented example config for reference.

Library

Wishlist is also available as a library, which allows you to start several apps within the same process. Check out the _example folder for a working example.

Auth

Local mode

When running in local mode, wishlist will first see if the current endpoint has an IdentityFile specified. If so, it'll try to use that. If not, it'll see if there's a SSH Agent available, and use it. Otherwise, it'll try the common key names in ~/.ssh.

Server mode

When running as a server, wishlist will first try to forward the current SSH Agent. If there's no agent, it'll create or use an existing ed25519 key present in .wishlist/client_ed25519. Password authentication is not supported at this moment.

Agent forwarding example

eval (ssh-agent)
ssh-add -k # adds all your pubkeys
ssh-add -l # should list the added keys

ssh \
  -o 'ForwardAgent=yes' \             # forwards the agent
  -o 'UserKnownHostsFile=/dev/null' \ # do not add to ~/.ssh/known_hosts, optional
  -p 2222 \                           # port
  foo.bar \                           # host
  -t list                             # optional, app name

You can also add this to your ~/.ssh/config, for instance:

Host wishlist
	HostName foo.bar
	Port 2222
	ForwardAgent yes
	UserKnownHostsFile /dev/null

Discovery

Wishlist can discover endpoints using Zeroconf, SRV Records, and Tailscale.

You can find a brief explanation and examples of all of them bellow.

Run wishlist --help to see all the options.

Tailscale

You can configure Wishlist to find all nodes in your tailnet and add them as endpoints:

wishlist --tailscale.net=your_tailnet_name --tailscale.key=tskey-api-abc123...

You can use the Hints to change the connection settings.

OAuth authentication

Tailscale API keys expire after 90 days. If you want something that doesn't require you to intervene every couple of months, use OAuth Clients:

Create a client here. The only scope needed is devices:read.

Instead of using --tailscale.key (or $TAILSCALE_KEY), set --tailscale.client.id and --tailscale.client.secret (or $TAILSCALE_CLIENT_ID and $TAILSCALE_CLIENT_SECRET, respectively).

Zeroconf/Avahi/mDNS/Bonjour

You can enable this using the --zeroconf.enabled flag:

wishlist --zeroconf.enabled

Optionally, you can also specify a timeout with --zeroconf.timeout and, which domain to look for with --zeroconf.domain.

Wishlist will look for _ssh._tcp services in the given domain.

You can use the Hints to change the connection settings.

SRV records

You can set Wishlist up to find nodes from DNS SRV records:

wishlist --srv.domain example.com

By default, Wishlist will set the name of the endpoint to the SRV target. You can, however, customize that with a TXT record in the following format:

wishlist.name full.address:22=thename

So, in this case, a SRV record pointing to full.address on port 22 will get the name thename.

Hints

You can use the hints key in the YAML configuration file to hint settings into discovered endpoints.

Check the example configuration file to learn what options are available.

If you're using a SSH configuration file as the Wishlist configuration file, it'll try to match the hosts with the rules in the given configuration. Otherwise, the services will simply be added to the list.

The difference is that if a hints themselves won't show in the TUI, as of hosts in the SSH configuration will.

Running it

Wishlist will read and store all its information in a .wishlist folder in the current working directory:

  • the server keys
  • the client keys
  • known hosts
  • config files

Config files may be provided in either YAML or SSH Config formats:

The config files are tried in the following order:

  • the -config flag in either YAML or SSH config formats
  • .wishlist/config.yaml
  • .wishlist/config.yml
  • .wishlist/config
  • [[user config dir]]/wishlist/config.yaml1
  • [[user config dir]]/wishlist/config.yml1
  • [[user config dir]]/wishlist/config1
  • $HOME/.ssh/config
  • /etc/ssh/ssh_config

The first one that is loaded and parsed without errors will be used. This means that if you have your common used hosts in your ~/.ssh/config, you can simply run wishlist and get it running right away. It also means that if you don't want that, you can pass a path to -config, and it can be either a YAML, or a SSH config file.

Using the binary

wishlist

Using Docker

mkdir .wishlist
$EDITOR .wishlist/config.yaml # either an YAML or a SSH config
docker run \
  -p 2222:22 \
  -v $PWD/.wishlist:/.wishlist \
  docker.io/charmcli/wishlist:latest
