You give regular users access to the OPERATING SYSTEM at the COMMAND LINE LEVEL?</i><i><span style='color:#1F497D'>”</span></i><i><br><br></i><span style='color:black'>What? I never said that, and I wouldn’t do it. Command line access to the OS? Do you think I’m that stupid? How would you do that with a DTMF command (ilink,4 = “Remote Command Mode”)? As I understand it, ilink,4 simply relays DTMF commands from one node to another. I fail to see how that’s a security risk.<o:p></o:p></span></p><p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:black'>For info, SSH (command line) access to my nodes has password access disabled and a pre-shared key is required.

I’m still fine-tuning, but the user simply enters a short-form DTMF sequence and the system takes over and sets-up the link. Another short sequence takes the link down again. All without Cylon activity, and all without anyone ever getting command-line access.<o:p></o:p></span></p><p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:black'>I am fortunate to live in an environment where paranoia is largely unjustified.
