Dear colleagues: I'm very interested in Rserve because I'm trying to model (time series) remotely using a terminal (Windows XP) over a database in a server (Windows Vista) by internet. My first question: Is Rserve the solution to work remotely with R (for time series analysis) with databases? If this is the solution I have the next problem: The client application of Rserve works over Windows XP and the side of the server works over Windows Vista. Both of them are not located in a local network but in differents buildings. The test of telnet works fine in the side of the server and the firewalls of the sides are disabled too. I don't know if the sintaxis: Rserve(debug = FALSE, port = 6311, args = "remote enable") is correct. Or when i try to run the command in windows: > Rserve.exe remote enable as administrator. The R error says: Error in socketConnection(host, port, open = "a+b", blocking = TRUE) : cannot open the connection In addition: Warning message: In socketConnection(host, port, open = "a+b", blocking = TRUE) : 190.129.41.230:6311 cannot be opened Thanks in advance for all your help.
