I haven't tried what you're trying to do before, but the syntax you're using mostly looks OK.

You haven't said what operating system you're using and that can make a difference for some versions of ssh. On most systems, the destination device has to follow the options, so there is a chance that it might work if you change:

Code:

#             -re "Connection refused|Connection timed out" { spawn ssh -o StrictHostKeyChecking=no $dev -l $unam }
             timeout { spawn ssh -o StrictHostKeyChecking=no $dev -l $unam
                     expect {
                            timeout { set err [ open "$hnam\_$dev.err" w ] ;
                                      puts $err "SSH timed out for $dev.\n";
                                      log_file ;
                                      exit; }

                             }

                     }
             }

to:

Code:

             -re "Connection refused|Connection timed out" {
                     spawn ssh -o StrictHostKeyChecking=no -l $unam $dev
                     expect {
                            timeout { 
                                      set err [ open "$hnam\_$dev.err" w ] ;
                                      puts $err "SSH timed out for $dev.\n";
                                      log_file ;
                                      exit;
                            }
                    }
             }
             timeout { spawn ssh -o StrictHostKeyChecking=no -l $unam $dev
                     expect {
                            timeout { set err [ open "$hnam\_$dev.err" w ] ;
                                      puts $err "SSH timed out for $dev.\n";
                                      log_file ;
                                      exit; }
                             }
                     }
             }

Obviously, this is totally untested. I would suggest that you turn on tcl's debugging output by including the -d option when you start it.

setcolor(1F)							   FMLI Commands						      setcolor(1F)

NAME

       setcolor - redefine or create a color

SYNOPSIS

       setcolor color red_level green_level blue_level

DESCRIPTION

       The  setcolor  command  takes four arguments: color, which must be a string naming the color; and the arguments red_level, green_level, and
       blue_level, which must be integer values defining, respectively, the intensity of the red, green, and blue components of  color.   Intensi-
       ties  must  be  in the range of 0 to 1000. If you are redefining an existing color, you must use its current name (default color names are:
       black, blue, green, cyan, red, magenta, yellow, and white). setcolor returns the color's name string.

EXAMPLES

       Example 1: A sample output of setcolor command.

       The following is an example of the arguments that setcolor takes:

       `setcolor blue 100 24 300`
