# SSHX
[](https://travis-ci.com/suutaku/sshx)
[](https://goreportcard.com/report/github.com/suutaku/sshx)
ssh p2p tunneling service. An enhanced version of
`https://github.com/nobonobo/ssh-p2p.git`.

## Backend protocol
* RTCDataChannel/WebRTC: [https://github.com/pion/webrtc/v3](https://github.com/pion/webrtc/v3)
* Signaling server: [http://peer1.xxxxxxxx.com:8990](http://peer1.xxxxx.com:8990)
Server is not stable, just for testing. **Please use your own signaling server on production**.
## Install
### Requirements
`https://github.com/go-vgo/robotgo #Requirements`
### Signaling server
```bash
go get -u github.com/suutaku/sshx/cmd/signaling
```
### SSHX
```bash
go get -u github.com/suutaku/sshx/cmd/sshx
```
### Install as a system daemon
#### Mac OSX & Linux
```bash
git clone https://github.com/suutaku/sshx
cd sshx
sudo ./build.sh install ## for sshx
sudo ./build.sh install signaling ## both sshx and signaling server
```
### Windows
I don't have Windows device so i don't know how to create and test install scripts, maybe some can write a script for windows user.
## Configuration
Configure file will created at first time at path: `$HOME/.sshx_config.json`. You can also set root path of sshx with `SSHX_HOME` environment value.
Default configure as below:
```json
{
"id": "dd88229c-ad13-4210-a1ad-3d59f12e0655",
"locallistenaddr": "127.0.0.1:2222",
"localsshaddr": "127.0.0.1:22",
"rtcconf": {
"iceservers": [
{
"urls": [
"stun:stun.l.google.com:19302"
]
}
]
},
"signalingserveraddr": "http://signalingserver.xxxxx.com:8990"
}
```
* `locallistenaddr` : sshx listen address.
* `localsshaddr`: server sshd listen address.
* `rtcconf`: STUN server configure.
* `signalingserveraddr`: signaling server address.
## Usage
* Signaling server
Specify server listening port by environment variable **PORT**, default **8080**.
```bash
export SSHX_SIGNALING_PORT=[port you want] #default port is 8080
signaling
```
* SSHX
Start sshx:
```bash
Usage: sshx COMMAND [arg...]
a webrtc based ssh remote toolbox
Commands:
daemon launch a sshx daemon
config list configure informations
connect connect to remote host
copy-id copy public key to server
copy copy files or directory from/to remote host
proxy start proxy
status get status
fs sshfs filesystem
Run 'sshx COMMAND --help' for more information on a command.
```
Daemoon
```bash
sshx daemon
```
**Note:** befor you run any command of sshx, you must run sshx as a daemon first.
List configure informations
```bash
sshx list
```
Connect a remote device with ID or IP(domain)
```bash
Usage: sshx connect [ -X ] [ -i ] [ -p ] ADDR
connect to remote host
Arguments:
ADDR remote target address [username]@[host]:[port]
Options:
-X, --x11 using X11 opton, default false
-i, --identification a private path, default empty for ~/.ssh/id_rsa
-p remote host port (default "22")
```
Copy a file or dierctory just like ssh does
```bash
Usage: sshx copy FROM TO
cpy files or directories to remote host
Arguments:
FROM file or directory path which want to coy
TO des path
```
Proxy
```bash
Usage: sshx proxy COMMAND [arg...]
manage proxy
Commands:
start start a proxy
Run 'sshx proxy COMMAND --help' for more information on a command.
```
VNC
sshx contained a `noVNC` client which write with Javascript. To use client just access `http://vnc.sshx.wz` (not working with VPN environment) or `http://127.0.0.1` and input device ID in setting menu.
Copy ID
```bash
Usage: sshx copy-id ADDR
copy public key to server
Arguments:
ADDR remote target address [username]@[host]:[port]
```
SSHFS
```bash
Usage: sshx fs COMMAND [arg...]
sshfs filesystem
Commands:
mount mount a remote filesystem
unmount unmount a remote filesystem
Run 'sshx fs COMMAND --help' for more information on a command.
```
Status
Show current connections
## Appliction
Using sshx, you can write your own NAT-Traversal applications by implement `Impl` at `github.com/suutaku/sshx/pkg/impl`:
```golang
type Impl interface {
// set implementation specifiy configure
Init(ImplParam)
// return the application code, see pkg/types/types.go
Code() int32
// Writer of dialer
DialerWriter() io.Writer
// Writer of responser
ResponserWriter() io.Writer
// Reader of dialer
DialerReader() io.Reader
// Reader of responser
ResponserReader() io.Reader
// Response of remote device call
Response() error
// Call remote device
Dial() error
// Close Impl connection
Close()
// Set pairId dynamiclly
SetPairId(id string)
}
```
basically, `Impl` can acts as a `Dialer` or `Responser`. A `Dialer` send an connection request to local node to tell it which application will used for this connection.
local node make a P2P connection to target device and `Responser` at target devie response your request. see more `pkg/impl/impl_ssh.go`.
