Skywire SSH app

SSH app implements SSH functionality over skywirenet.

SSH-cli is used to initiate communication via client RPC exposed by SSH app.

SSH app implements common SSH operations:

• starting remote shell
• and executing commands remotely

PubKey whitelisting is performed by adding public key to the authentication file ($HOME/.therealssh/authorized_keys by default).

** Local setup

Create 2 node config files:

skywire1.json

{
  "apps": [
    {
      "app": "SSH",
      "version": "1.0",
      "auto_start": true,
      "port": 2
    }
  ]
}

skywire2.json

{
  "apps": [
    {
      "app": "SSH-client",
      "version": "1.0",
      "auto_start": true,
      "port": 22
    }
  ]
}

Compile binaries and start 2 nodes:

$ go build -o apps/SSH.v1.0 ./cmd/apps/therealssh
$ go build -o apps/SSH-client.v1.0 ./cmd/apps/therealssh-client
$ go build ./cmd/SSH-cli
$ ./skywire-visor skywire1.json
$ ./skywire-visor skywire2.json

Add public key of the second node to the auth file:

$ mkdir /.therealssh
$ echo "0348c941c5015a05c455ff238af2e57fb8f914c399aab604e9abb5b32b91a4c1fe" > /.SSH/authorized_keys

Connect to the first node using CLI:

$ ./SSH-cli 024ec47420176680816e0406250e7156465e4531f5b26057c9f6297bb0303558c7

This should get you to the $HOME folder of the user(you in this case), which will indicate that you are seeing remote PTY session.
