WebTTY - Remote Terminal

CGO_ENABLED=0; go build -o webtty -ldflags="-s -w" -trimpath main.go

To provide a password protected root terminal on http://localhost:8080 you can use the following (it is advisable to put HAProxy in front of WebTTY to provide TLS, as well as using this internally and not using it over the public Internet):

sudo useradd -r -d / webtty
sudo runuser -l webtty -c "/usr/local/bin/webtty /usr/bin/su -l root"

To configure it as a service use the following:

cat <<EOF | sudo tee /etc/systemd/system/webtty.service 1>/dev/null

Description=WebTTY - Remote Terminal

ExecStart=/usr/local/bin/webtty /usr/bin/su -l root

User=webtty

[Install]

sudo systemctl daemon-reload

sudo systemctl enable --now webtty.service

sudo systemctl status webtty.service

WebTTY - File Transfer

It also supports a simple File Transfer capability using the -ft argument to specify a directory for storage, which can then be used via the following curl commands:

Upload

curl -T <file> http://localhost:8080/ft/

/ft/<uuid>/<file>

Download

curl -Of http://localhost:8080/ft/<uuid>/<file>
