Networking

The Splat Space firewall is a NetScreen 5GT WLAN running ScreenOS 5.4r12 - the config as of 5/10/2011 is uploaded to this file: Media:20110510-5gt-config.doc Manuals for the ScreenOS 5.4 can be found on the Juniper website. The most useful is the Concepts & Examples Guide, which is a 25MB PDF.

If you change the firewall config, please upload a new copy of the config - with a new name! - so this page is up to date.

Many Splatters know the administrative userid and password - please check with Lisa, Mike, Justis, or Lenore if you need it.

Description and Charter

  • Splat Space has a permanent, freely available 1/4gb (rev 1) model B Raspberry Pi with hostname "splatpi". It is running latest (mid-December, 2012) Raspbian (aka Debian 7 aka wheezy) with patches current as of the end of January 2013. Its /boot filesystem is on an SD card as usual, but all other filesystems are on a 3 1/2" disk drive.
  • The physical hardware is to be left undisturbed and caution must be used with superuser software commands, but there are no other restrictions on use.

Access =

  • Example GUI access (renders a 1024x768 desktop):
    • vncviewer 192.168.2.61
  • Example text interface login:
    • "ssh -l pi 192.168.2.61" for the Genuine Linux Experience(tm).

Todo List

  • Set up bonjour (or a local DNS server) so the name "splatpi" can be used instead of the IP address
  • Nicer and maybe randomly variable desktop background graphics
 I couldn't get the LAN repeater box just below the switch to cooperate, but possibly because the cable I fetched originally from the "corner of cables" was defective (back on the pile, but marked defective now). I put one of my cables in place temporarily and will properly dress something through the rack on the next trip. But I also couldn't determine the least used switch position to temporarily swipe until the port expansion is worked out. For the moment the system is using the "north1" cable. It would be harmless to reassign ports.
 I ran out of time for a printed cheat sheet, but perhaps this could be added to the white board?
     Raspberry Pi system "splatpi" at 192.168.2 (access with vncviewer or ssh with -l pi and passwd raspberry)
The other thing on the list for the next trip is to see if bonjour can be set up, enable the ipv6 stack (forgot to do that), download a few Scratch "programs", etc.
 It might be fun to arrange alternative screen icons/background images.
