Colleagues
I am working in a Linux OS with R 2.6.2.
I need to execute a telnet session to another Linux machine from R,
perform some operations, then return to the original computer. When I
am in an R session, this is easy to accomplish by typing:
system("telnet -l username machinename")
I am then asked for my password; once that is entered, I am connected
to the remote machine. I can then enter commands on the remote
machine, then logout.
I would like to automate this process within a function. Obviously, I
can embed the 'system' command in the function.
Questions:
1. How do I enter the password into the command?
2. How do I execute the commands on the other machine?
3. Finally, how do I execute the 'logout' command (this should not
differ from #2)?
Thanks in advance for any help on this.
