Simple wrapper over mscdex/ssh2 to make your in-app SSH server using chjj/blessed for presentation layer.
npm install sshbbs
or
yarn add sshbbs
Generate your host keys using:
ssh-keygen -f host.key -N '' -t rsa
Use following example as a reference:
const
fs = require('fs'),
blessed = require('blessed'),
sshbbs = require('sshbbs')
sshbbs({
host: '127.0.0.1',
port: '52222',
passwords: {
hello: 'world',
},
keys: {
test: fs.readFileSync('authorized_keys'),
},
hostKey: fs.readFileSync('host.key'),
}, (screen, login) => {
// This will be called on every successful connection
let mainScreen = blessed.box({
parent: screen,
top: 0,
left: 0,
width: '100%',
height: '50%',
align: 'center',
valign: 'middle',
border: {
type: 'line',
},
content: `Welcome, ${login}! Press 'q' to quit.`,
style: {
fg: 'yellow',
bg: 'black',
border: {
fg: 'grey',
}
}
})
let counter = blessed.box({
parent: screen,
top: '50%',
left: 0,
width: '100%',
height: '50%',
align: 'center',
valign: 'middle',
border: {
type: 'line',
},
content: `Here we go!`,
style: {
fg: 'white',
bg: 'black',
border: {
fg: 'grey',
}
}
})
screen.key(['C-c', 'q'], (ch, key) => {
screen.destroy()
})
let cnt = 0
let intrv = setInterval(() => {
if (screen.destroyed) {
clearInterval(intrv)
return
}
cnt++
counter.setContent(`Counter ${cnt}`)
console.log(cnt)
screen.render()
}, 1000)
screen.render()
}).then((port) => {
console.log(` -- listening at ${port}`)
})This will start a SSH server on 127.0.0.1:52222, which accepts login hello with password world or login test with public key in authorized_keys file.
Connect using:
ssh -p 52222 hello@127.0.0.1
Have fun!
