rpc {pbdRPC} | R Documentation |
Launch a command via ssh or plink on a (remote) server.
rpc(cmd = "whoami", exec.type = .pbd_env$RPC.LI$exec.type, args = .pbd_env$RPC.LI$args, pport = .pbd_env$RPC.LI$pport, user = .pbd_env$RPC.LI$user, hostname = .pbd_env$RPC.LI$hostname, priv.key = .pbd_env$RPC.LI$priv.key, priv.key.ppk = .pbd_env$RPC.LI$priv.key.ppk, intern = .pbd_env$RPC.CT$intern, wait = .pbd_env$RPC.CT$wait)
cmd |
the command to be executed on the server. |
exec.type |
either "ssh" or "plink" in character. Windows will force to use "plink". |
args |
further arguments to "ssh" or "plink" for connecting to the server in addition to port, user id, and host name. |
pport |
ssh port opened on the server. |
user |
user id for logging to the server. |
hostname |
the server ip or host name. |
priv.key, priv.key.ppk |
location of the private key for user authentication, the file will be
checked first then |
intern, wait |
arguments passed to |
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.
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.
