- Signaling server: http://peer1.xxxxxxxx.com:8990
Server is not stable, just for testing. Please use your own signaling server on production.
https://github.com/go-vgo/robotgo #Requirements
go get -u github.com/suutaku/sshx/cmd/signalinggo get -u github.com/suutaku/sshx/cmd/sshxgit clone https://github.com/suutaku/sshx
cd sshx
sudo ./build.sh install ## for sshx
sudo ./build.sh install signaling ## both sshx and signaling serverI 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.
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:
{
"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.
- Signaling server Specify server listening port by environment variable PORT, default 8080.
export SSHX_SIGNALING_PORT=[port you want] #default port is 8080
signaling- SSHX
Start sshx:
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
sshx daemonNote: befor you run any command of sshx, you must run sshx as a daemon first.
List configure informations
sshx listConnect a remote device with ID or IP(domain)
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
Usage: sshx copy FROM TO
cpy files or directories to remote host
Arguments:
FROM file or directory path which want to coy
TO des pathProxy
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
Usage: sshx copy-id ADDR
copy public key to server
Arguments:
ADDR remote target address [username]@[host]:[port]SSHFS
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
Using sshx, you can write your own NAT-Traversal applications by implement Impl at github.com/suutaku/sshx/pkg/impl:
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.
Features
- Connect devices directly like ssh client does
- Private key loggin
- X11 forwarding
- Connect devices behind NAT
- Copy file or directory like scp does
- Custom device ID
- Custom signaling server
- Multiple connection with one remote device
- A simple signaling server implementation
- Pure go (due the
github.com/go-vgo/robotgo) - Lunux system service supporting
- VS Code SSH remote suportting (use proxy way due the VS Code not an open source project)
- VNC supporting (both vnc server and client)
- Ssh-fs supporting
