Printer Setup on a Solaris 8 Workstation

Here is a little post to give a hint about setting up a printer on a Solaris 8 Workstation :

# lpadmin -p printerName -s printServer
# lpadmin -p printerName -D "Printer description text"
# lpadmin -d printerName
# lpstat -p printerName

and then check you can print with :

# echo test | lp

Sun T3 StorEdge : Batteries refresh …

if you get this kind of “error” :
Dec 14 02:36:31 hostname StoreX (Dec 14, 2005 2:36:31 AM FQDN):P3:System hostname-t3 (XX.XX.XX.XX) - Unit-unit-1 - Power-Module-2 (u1pcu2) : Power supply unit has switched to battery. Fru ID: u1pcu2, Model: 300-1454-01(50), Serial Number: XXXXXX
Dec 14 02:58:31 hostname StoreX (Dec 14, 2005 2:58:30 AM FQDN):P3:System hostname-t3 (XX.XX.XX.XX) - Unit-unit-1 - Power-Module-2 (u1pcu2) : The FRU has some error. Fru ID: u1pcu2, Model: 300-1454-01(50), Serial Number: XXXXX

then be aware that a T3 performs a battery refresh every so and then (this is by default every 28 days, but can be modified in /etc/schd.conf). This battery refresh can provoke this kind of error messages which are no error at all …

Sun T3 StorEdge : Identifying a failure

when logged on the T3, you can see the state of each FRU with the command

fru stat

Example :

hostname-t3:/:fru stat

Parsing an ICal file with Perl

I finally almost got it …

Here is a code snippet for parsing and showing pieces of an ICal file :

use strict;
use warnings;

use Data::ICal;
use Data::ICal::DateTime;
use DateTime;

my $cal = Data::ICal->new(filename => 'holidays.ics');

my @events = $cal->events();

foreach my $event (@events) {
        print "summary:", $event->property('summary')->[0]->value, "n";
        print "dtstart:", $event->start, "n";
        print "dtend:", $event->end, "n";
}
print DateTime->now, "n";

What I want to do ? Drive my home automation events with my Mozilla Calendar !! I’ll soon be there, if I gather enough time to do it !

Some pointers :

  • DateTime perl module : a hell of a lot of computations with dates and times
  • Data::ICal perl modules : for all the parsing stuff
  • Data::ICal::DateTime perl module : to get it to work with DateTime
  • Home automation

    This is related to one of my geek hobbies : I am playing with home automation.

    Here is what I use :
    * Technology : x10
    * Software : MisterHouse
    * Hardware : a CM11, few AM12, LM12 etc

    This is really great since it allows you to control anything in your house (lights, washing machine, heaters, …) from your computer, while still being fairly simple.

    Using MisterHouse requires to know at least a little bit of Perl to get the most out of it, though.

    First post !

    Hello,

    My name is Stephane Kattoor, I work as an IT Engineer, and I created this blog with the idea to use it to store the little technical tips or hints I find in my every day work … with the hope it will help me and perhaps some others as well !

    Come from time to time, I plan to keep it updated !
