This probably has to do with your ssh configuration and nothing to do
with R. How are you starting Rserve? Is it run with the same user
privileges as when you run R manually?

Hello,
I've installed an Rserve instance on a remote server. I have no problem
interfacing with it and running most commands. I have loaded some R
scripts on the remote server, and one of them contains a system command
to copy a file (created by the script) onto another server. When I run
the script on the remote server itself, the script works as I intend: it
creates a .csv file and uses scp to copy it onto another server. When I
run the script remotely (through an Rconnection in Java), the .csv is
created but the file is not copied onto the other server. Is there any
reason why a system command would work when called locally but not when
called remotely?
The format is as follows:
# create array
write.csv(array, "array.csv")
system("scp /{path}/array.csv {remote server}:/{path2}")
Again, the script works correctly when run through R on the remote
server, but when I run it through Rserve, everything works except for
the 'system' command. Any insights would be greatly appreciated.
Thanks a lot,
Prasad
