ztui: your one-stop shop for ZeroTier terminal UI goodness

ztui aims to be a frontend for all interactions with ZeroTier in an attempt to transform how people work with it. It provides the following features:

• Main Screen:
  • Bookmarks for Networks (disconnecting does not make the network id disappear from the list, and you can rejoin easily)
  • Interaction directly with Central members from the network list.
  • Joining, Leaving Networks
  • Per-Network bandwidth statistics
  • Bind arbitrary commands to keys that use a template to launch (see more on this below)
  • Review the network JSON formatted pretty
  • Launch $EDITOR against a file of network rules (and save them back to central)
• Central / Member List:
  • Rename members
  • Auth, Unauth, and Delete members

Installing

Get Rust 1.60 or better if you need to. You'll need it.

cargo install ztui

Configuring arbitrary commands

Rules

• Command must not be mapped by existing commands
• Will be executed in a shell; quote accordingly

Configuration Syntax

After you start ztui for the first time, $HOME/.config.zerotier/settings.json will be created for you with your last-saved network information. Now, what we want to do is create $HOME/.config.zerotier/config.json and add something like this:

json { "network_commands": { "1": "/bin/tcpdump -i %i" }, "member_commands": { "1": "/bin/iperf -c %a" } }

Network format strings available:

• %i: the interface of the ZeroTier network
• %n: the network ID of the ZeroTier network
• %a: the first addresses in the list of assigned IP addresses

In this case, it would allow me to press 1 over a network to tcpdump its interface; then I would control+C out of it to come back to ztui.

Member format strings available:

• %n: the network ID of the ZeroTier network
• %i: the identity of the member of this ZeroTier network
• %a: the first assigned IP address of this member
• %N: the name (not the fqdn!) of the ZeroTier network member as it appears in central

In the above example, it allows me to start an iperf client against the address of the selected member.
