Darth Vader Meets Tech Support
Darth Vader took two giant strides toward the immense visiscreen
that occupied the forward wall of the bridge of his flagship
Imperial star destroyer. "We've got them now," he rumbled.
Whirling on the technicians cowering at their consoles, Vader
snapped, "Tractor beam!"
"Yes, Lord Vader," replied one, bending attentively
to his task. Then he looked up hesitantly.
Vader gestured dramatically at the screen, indicating the
fleeing
spacecraft. "I want a tractor beam on that ship," he
declared. "Now!"
The technician busied himself with switches and dials.
"Where's that tractor beam?" roared Vader, his voice
dark with menace.
The other technicians turned frightened eyes on their peer.
They knew what happened when Darth Vader's instructions weren't
executed instantly. "The tractor beam seems to be down,
sir," quavered the technician.
"What do you mean down?" Vader inquired with a disturbing
silkiness to his voice.
"It's not accepting commands, sir," the technician
explained.
Another technician leaned over and examined the console. "That's
odd. The beam itself is showing green," he pointed out.
"Yes, I know," agreed the first.
"But I'm not getting any acknowledgment to my 'Engage'
command." He pressed a button several times to demonstrate.
"Maybe the network's down again," suggested a third
technician.
"Oh, that could be," admitted the first technician.
"The network
might be down, Lord Vader," he informed the large black
figure trembling with rage.
"What network?" Vader asked ominously.
The second technician jumped in. "Since we've moved to
a distributed architecture on the Imperial star destroyers, everything
is on a network. It was felt that the direct connections were
too unreliable."
The third technician added. "The tractor beam is on one
of the
peripherals sub networks, with the printers and the scanners.
It's not on the main weapons network."
"Why isn't the tractor beam on the weapons network?"
asked Vader, now more puzzled than angry.
The technicians exchanged sheepish looks. It was embarrassing
to have to point out something so obvious to a superior.
The second technician cleared his throat. "Well, sir,
the weapons network is a higher priority. It makes more sense
to put the less commonly used systems on a separate sub network
that has lower QOS."
"QOS?" Vader queried.
"Hang on a second," said the first technician. "If
the network is down, how come we're getting a green light for
the tractor beam?"
The third technician brightened. "Ah! Maybe the console
is retrieving old MIB data and displaying that."
"MIB?" rumbled Vader.
The first technician answered "We use SNMP to monitor
the network elements. When the server queries the element, it
stores its current status. If the network goes down, it can't
query the element anymore, and all you have is the latest status
in the MIB." He turned to the other technicians, musing.
"We really should have an indicator of when the last successful
query was, instead of just a green or red light."
"Good idea," said the third technician. "I'll
call tech support."
"Say," said the second technician. "How about
if we ping the tractor beam? Let me bring up a telnet window."
"Telnet?" asked Vader, now obviously confused. "Ping?"
The first technician glanced briefly at Vader, a little annoyed
at the interruptions. Why couldn't this guy keep up with the
service bulletins? "The system runs Unix, but the consoles
run NT 5000," he replied with exaggerated patience. "You
need a telnet window to ping the element." He turned his
attention back to the screen. "That's strange. It comes
back 'active'. Listen, when you get tech support tell them we
can't engage the tractor but we can ping it."
"Right," said the third technician. "I'm still
on hold."
"Here's a thought," said the second technician. "What
if we just call the guys down at tractor control and have them
engage the beam manually?"
Vader seemed to brighten up at this, and swiveled his head
from one to another.
"Good idea," said the first technician. He lifted
his communicator and tapped the switch several times. "Nothing,"
he said.
The second technician shook his head. "Didn't we tell
them we couldn't do voice and data with that little bandwidth?"
Suddenly Vader noticed the visiscreen and let out a bellow
of anger. "They're gone!" he boomed.
The third technician looked up smiling. "Hey, I got tech
support!"
