This England

"This royal throne of kings, this sceptred isle,
 This earth of majesty, this seat of Mars,
 This other Eden, demi-paradise,
 This fortress built by Nature for herself
 Against infection and the hand of war,
 This happy breed of men, this little world,
 This precious stone set in the silver sea...
 This blessed plot, this earth, this realm, this England."

 William Shakespeare, 1564-1616, Richard II, Act 2, Scene 1 
 (JOHN OF GAUNT (Duke of Lancaster) speaks)

For information on the kludges make this Skycam come alive?

• The Kludge that is my crontab file
• Grabbing the image (adpated from the SGI Indycam "snap" script)
• Dynamically setting the IndyCam Shutterspeed and Settings script
  (Script from Adrie Kooijman's website: http://www.io.tudelft.nl/~adrie/IndyShutter)
• Make a new Archive Directory for each new day
• Copy image files to the archive twice a day as per the crontab file
• Script for having an image delivered on demand
  (Script from Christopher Spry's website: http://sprysgi.sghms.ac.uk/~cspry/computing/Indy_admin/IndyCam.html) (from)

• The /etc/mtab setting on the local Indy
  webserver.ccp14.ac.uk:/web_disc/ccp14/web_area/web_live/people/lachlan/indycam /indydirectory/indycam nfs vers=3,rw,intr,bg,dev=c0001 0 0
• The /etc/exports setting on the webserver
  /web_disc/ccp14/web_area/web_live/people/lachlan/indycam -rw,access=indy.name
• The /usr/etc/portmapper security setting on the webserver to limit hacker portmapper/mountd/rpc probes
  (As run on initialisation in /etc/init.d/network. Do a "man portmap". This can be reconfigured and restarted without rebooting using Wietse Venema's portmapper utilties)
  

  -v
  -a 255.255.255.255,indy-ip-address

• Then using Wietse Venema's portmapper program do the following sequence of commands to be able to restart the "IRIX" portmapper without having to reboot the machine.

  ./pmap_dump > table
  killall portmap
  /usr/etc/portmap `cat /etc/config/portmap.options`
  ./pmap_set < table

• Also do a man ipfilterd

• "For constant inside illumination, REM out the indyshutter script and try the following for setting up the Indycam: Run capture Then in the menu system: "Options" "Video Panel" "Pro, Indycam, Signal Controls" And manually tweak the controls so the balance, lighting is happy. When you exit "capture", this setting should be retained for when your script is applied."

This page originally started life from the webpage - on the World War I patriotic poem telling how "The Surreys Played the Game"

"On through the heat of slaughter
Where gallant comrades fall
Where blood is poured like water
They drive the trickling ball
The fear of death before them
Is but an empty name
True to the land that bore them
The Surreys play the game"
