Telebit

| Telebit Client | Telebit Relay | Telebit Mgmt |

A secure, end-to-end Encrypted tunnel.

Because friends don't let friends localhost.

Usage

telebit --env ./.env --verbose

Command-line flags or .env may be used.

# --acme-agree
export ACME_AGREE=true
# --acme-email
export [email protected]
# --vendor-id
export VENDOR_ID=example.com
# --secret
export SECRET=YY-device-shared-secret-YY
# --tunnel-relay
export TUNNEL_RELAY_URL=https://tunnel.example.com/
# --locals
export LOCALS=https:*:3000
# --tls-locals
export TLS_LOCALS=https:*:3000

See ./telebit --help for all options.
See examples/client.env for detail explanations.

System Services

You can use serviceman to run postgres, telebit, and telebit-mgmt as system services

curl -fsS https://webinstall.dev/serviceman | bash

See the Cheat Sheet at https://webinstall.dev/serviceman

You can, of course, configure systemd (or whatever) by hand if you prefer.

Example Local Web Application

The simplest way to test the tunnel is with a local web server.

mkdir -p tmp-app
pushd tmp-app/

cat << EOF > index.html
Hello, World!
EOF

Ex: Caddy

curl -sS https://webinstall.dev/caddy | bash
caddy file-server --browse --listen :3000

Ex: Python 3

python3 -m http.server 3000

Build

git clone ssh://[email protected]:root/telebit.git
pushd telebit/

You can build with go build:

go generate -mod=vendor -tags postgres ./...
go build -mod vendor -tags postgres -race -o telebit cmd/telebit/*.go

Or with goreleaser:

goreleaser --rm-dist --skip-publish --snapshot

See https://webinstall.dev/goreleaser for cheat sheet.

Install Go

To install Go (on any of Windows, Mac, or Linux), see https://webinstall.dev/golang.

Installs Go to ~/.local/opt/go.

Mac, Linux:

curl -fsS https://webinstall.dev/golang | bash

Windows 10:

curl.exe -fsSA "MS" https://webinstall.dev/golang | powershell

Note: The minimum required go version is shown in go.mod. DO NOT use with GOPATH!

Building Telebit

All dependencies are included, at the correct version in the ./vendor directory.

go generate -mod vendor ./...

CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -mod vendor -o telebit-linux ./cmd/telebit/*.go
CGO_ENABLED=0 GOOS=darwin GOARCH=amd64 go build -mod vendor -o telebit-macos ./cmd/telebit/*.go
CGO_ENABLED=0 GOOS=windows GOARCH=amd64 go build -mod vendor -o telebit-windows-debug.exe ./cmd/telebit/*.go
CGO_ENABLED=0 GOOS=windows GOARCH=amd64 go build -mod vendor -ldflags "-H windowsgui" -o telebit-windows.exe ./cmd/telebit/*.go

The binary can be built with VENDOR_ID and CLIENT_SECRET built into the binary. You can also change the serviceName and serviceDescription at build time. See examples/run-as-client.sh.
