rpc: Remote Procedure Call

In pbdRPC: Programming with Big Data -- Remote Procedure Call

Description

Launch a command via ssh or plink on a (remote) server.

Usage

rpc(machine, cmd = "whoami", intern = .pbd_env$RPC.CT$intern,
  wait = .pbd_env$RPC.CT$wait)

Arguments

machine	A machine configuration. See ?machine.
cmd	the command to be executed on the server.
intern, wait	arguments passed to system() or shell() whereever they are applicable.

Details

Using either ssh or plink to launch a command on a (remote) server. Authentication is working currently for ssh.

NO further input from stdin is expected. Outputs or errors may not be captured by R.

Value

Mainly the message received from the command line of server may be returned but may not be captured by R.

For example, Windows with plink will not capture the return because currently the authentication is not working. A windows bat file is launched by shell.exec() in an additional cmd.exe window to avoid saving password inside R.
