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.
