As explained by James Carlson:
The reason it was like this was historical: getting the
MAC address in ifconfig meant opening up the DLPI node
and talking to the driver. As the drivers didn't have
discrete privileges for each operation, and you had to be
almighty root to touch them, 'ifconfig' didn't show the
MAC address when not privileged.
*whatever*
The second solution is to use arp. In Solaris you can determine the physical address by looking at the arp tables directly (`arp -a | grep <INTERFACE>` or `netstat -p | grep <INTERFACE>`). With C, this can be done by using the if sockets and arp libraries.
I wrote up a solution called "getmac" using both methods. You can gather it here.

$ wget http://www.pauliesworld.org/project/getmac.c $ gcc getmac.c -o getmac -lsocket -ldlpi $ ./getmac <interface_name> arp: ffffffffffff dlpi: dlpi failure, are you root? $ pfexec ./getmac <interface_name> arp: ffffffffffff dlpi: ffffffffffff

vi upnp/src/api/upnpapi.cOn line 59, there is a bug. Change
#if defined(_sun)to
#if defined(__sun)The change is adding an extra underscore. Otherwise sockio.h will not be recognized properly and you will get some missing networking variables when you try to build. After that is taken care of...
$ ./configure CFLAGS="-DSPARC_SOLARIS" --disable-samples $ gmake # gmake install

Measuring in at around 115 x 101 x 27mm (~ 4.5"x4.0"x1.0"), it is only big enough to hold one laptop sized 2.5" SATA drive.
The drive I installed only has 80GB of space. That would run out real quick with my needs, so I decided to get a MediaSonic USB disk enclosure to link up with my server. It can hold up to 4 SATA drives.
The PC sits on top of the enclosure on my bookshelf taking up 8.5" x 5.0" x 6.5" amount of space. This is not only power efficient, but space efficient since I am using 4 x 1TB drives. 4TB total (theoretical), ~2.6TB in a ZFS raidz. If I were to have purchased the 2TB drives, it would be even better.
Doug's blog on the FIT-PC2 gives a good overview on the features of the device and what works. There is no wifi driver and Xorg doesn't work, so you may want to install OpenSolaris on another machine before installing the internal HDD. My server is headless and uses the built-in gigabit ethernet, so I don't care about those issues.

So, I decided to write my own script that uses SendEmail. All you need to do is edit the $SENDEMAIL, $SRCEMAIL, $DESTEMAIL, and $SMTPSERVER variables. It's a VERY simple script, so don't expect a lot from it. You can always substitute sendEmail for sendmail, and you may want to add some extra options for username and password if your SMTP server requires it (mine doesn't).
use strict;
use vars qw($VERSION %IRSSI);
use Irssi;
$VERSION = '1.0.0';
%IRSSI = (
author => 'Paul Johnson',
contact => 'paulie@pauliesworld.org',
name => 'E-mail PM',
description => 'E-mails a private message to you
from IRC.',
url => 'http://www.pauliesworld.org/emailpm/',
changed => '$Date: 2009-01-09 :00:00 +0100
(Sat, 9 Jan 2009) $'
);
my $SENDEMAIL = "/location/of/sendEmail";
my $SRCEMAIL = "source\@emailaddress.com";
my $DESTEMAIL = "destination\@emailaddress.com;
my $SMTPSERVER = "smtp.youremailserver.com";
sub parsePrivateMessage()
{
my ($server,$message,$user,$address,$target) = @_;
emailPrivateMessage($user,$message);
}
sub emailPrivateMessage()
{
my ($user,$message)=@_;
my $subject = "IRC message from $user";
my $send=`${SENDEMAIL} -f ${SRCEMAIL} -t ${DESTEMAIL}
-u ${subject} -m ${message} -s ${SMTPSERVER}
}
Irssi::signal_add_last("message private",
"parsePrivateMessage");

Some answers:
Model: Linksys WVC54GCA Wireless G Home Monitoring Camera
FTP/SSH support: Nope
Capturing Live Images
So how do I automate taking pictures with the thing? Well, a hidden feature to the camera is to navigate to the static picture site of the webcam. For my example, I use DNS to map my camera hostname garfunkel to its IP address. You may want to enter whatever IP your camera uses instead of garfunkel.
http://garfunkel/img/snapshot.cgi?size=3&quality=1To grab a picture at any given time, use wget.
wget http://garfunkel/img/snapshot.cgi?size=3\&quality=1If you have a UNIX-based or UNIX-like OS, you can schedule a cron job to grab this image as often as you like. I prefer capturing once every half hour, so I use this template:
-O webcam.jpg
*/30 * * * * /path/to/wget/scriptNow, if you have your own web page, you can use ftp/sftp/scp to upload the picture to your server using one script.
Creating Time-Lapse Videos
If you can capture a picture once every minute, you can create a pretty neat time-lapse video every day. This can be accomplished using wget and ffmpeg. For my camera, I point it outside, so it's only worth capturing between certain hours, say 6am to 6pm. After 6pm, I will have created over 700 pictures. I can then use ffmpeg to stitch them together to form a short video on the day's weather. It's a little complicated to discuss every detail behind this, so I'll just post the bourne script I use.
#!/bin/sh
hour=`date +%H`
captime=`date +%H%M`
dirpath="/location/of/your/timelapse/directory"
img=`ls ${dirpath}*jpg | wc -l`;
expr=`expr 1 + $img`
timelapse()
{
# File format will be Month.Day.Year.flv (flv for
# flash)
date=`date +%m.%d.%y.flv`
# ffmpeg reads in each image and incrementally
# makes a flash video at 16 fps
cd ${dirpath}
ffmpeg -i %04d.jpg -r 16 ${dirpath}${date}
# Cleanup, upload time-lapse to server and remove
# all jpg files
# scp user@host:location
# rm ${dirpath}*jpg
}
capture()
{
# ffmpeg expects pictures in the format 0001.jpg ...
# 0001.jpg so we need to add a fluff of zeros to
# make each pic 4 digits long
if [ $expr -lt 10 ]
then
expr="000${expr}"
elif [ $expr -lt 100 ]
then
expr="00${expr}"
elif [ $expr -lt 1000 ]
then
expr="0${expr}"
fi
wget http://garfunkel/img/snapshot.cgi?size=3\&quality=1
--output-document=${dirpath}${expr}.jpg
}
case "$hour" in
# Eliminate the hours of the day that are too dark to capture
00|01|02|03|04|05|19|20|21|22|23)
;;
# If it is 6:00pm (18), time to make a video
18)
if [ $captime -eq 1800 ]
then
timelapse
fi
;;
# Every other hour is assumed to have light, so take a pic
*)
capture
;;
esac
You might want to change the dirpath variable to wherever you want to store
the pictures. Finally, add a cron entry to run every minute:
* * * * * /path/to/timelapse/scriptAfter 6pm, you will have an flv file. This is a flash file that can be played by various flash players for viewing on the web. You can change the file format to avi or mpg instead of flv if you just want to view it on your computer.

Solution to turn it off
System -> Preferences -> Assistive Technologies -> Keyboard Accessibility -> Mouse Keys Uncheck 'Pointer can be controlled using the keypad'I must admit, however, this can be a handy feature when working with a mouse-less machine.

rm: cannot remove directory `asdf/': File exists... you will notice that conventional methods won't be good enough to remove it.
$ chmod -R 777 asdf/ $ rm -rf asdf/ $ rm: cannot remove directory `asdf/': File existsUsually there is a file like .nfs234B inside the directory than can be displayed with ls -la
$ ls -la total 146 drwxr-xr-x 2 user group 512 2009-05-20 08:51 . drwxr-xr-x 3 user group 512 2009-05-19 08:59 .. -rwxr-xr-x 1 user group 134888 2009-05-18 12:45 .nfs234BRemoving this file only replaces it with another. There are two solutions: manually delete the file on the NFS server, or (if you don't have that type of access) kill its process.
$fuser -u asdf/.* asdf/.: 9070c(user) asdf/..: 28690c(user) 24845c(user) asdf/.nfs934B: 9070tm(user)9070 is the offending process. Kill it with fire.
$ kill -9 9070Should be able to remove that directory now.
