So......how did your hair turn out since the cut and paste didn't work out so
well? :)

Cut and paste getting my hair and make up "did". ;)
Point well taken.

Bob D is 100% correct, utwho (or anything that invokes or could tie up
authd) can be dangerous. Can't stress this enough for custom kiosk
creation, though I understand that yours isn't in the kiosk script.
I'm a big believer in keeping things simple. There's really no reason
to use perl here.
While the following isn't "supported" because we don't guarantee that
the files in /tmp/SUNWut/config won't change, it works very nicely and
is a lot less "lines of code"
#!/bin/sh
MYDISP=`echo $DISPLAY | awk -F: '{print $2}' | awk -F. '{print $1}'`
MYTERM=`grep TERMINAL /tmp/SUNWut/config/dispinfo/$MYDISP | awk -F.
'{print $2}'`
/opt/SUNWut/bin/utwho -c |grep $MYTERM | awk '{print $4}'
That could be simplified as well for less invocations of awk/grep. With
respect, Craig, there's never an excuse for more than one invocation of
sed/awk/grep on the same input string. It's inefficient and unnecessary.
To get IP address, I would simplify your script as follows:
MYDISP=`echo $DISPLAY | awk -F: '{ split($2,a,"."); print a[1] }'`
MYTERM=`awk -F. '/^TERMINAL_ID=/ {print $2}'
/tmp/SUNWut/config/dispinfo/$MYDISP`
/opt/SUNWut/bin/utwho -c | awk "/${MYTERM}\$/ { print \$4 }"
Also note the additional pattern constraint anchors on the 2nd and 3rd
lines. That might help future-proof this approach somewhat.
Sorry - I just couldn't resist :-)

Murray, Thank you!
Thanks for all the replies. I did get my script working by
verifying the user name field from the utwho output first. If I
couldn't find the prefix of my kiosk account then adjust my array
index accordingly.
But this script is what I think I'm looking for, thanks for this
sample Code! I don't think I need to worry about overloading the
utauthd, as this script wouldn't be called at a kiosk session start
up but only when a user sits down and selects what desktop
environment they want to work in.

utwho is a script as well, have a read of /opt/SUNWut/bin/utwho
essentially, if you open a tcp socket to port 7010, and send 'status',
you will get all the information you need, and a lot more.
You can use perl to put it all together (each record is between a
'begin' and 'end' line). I think you want the 'terminalIPA' line for
the ip address, and 'connected=true' for connected.

I'm currently trying to figure out the correct IP address for the
DTU using
the following perl script:
#!/usr/bin/perl
my $line;
my @array;
my $ip;
my $junk;
my $user = $ENV{USER};
open(WHO, "/opt/SUNWut/bin/utwho -c|");
open(LOG, ">>/tmp/log.txt");
while (<WHO>) {
$line = $_;
@array = split (' +\s', $line, 5);
print LOG "User: $user $array[1]\n";
if ($user eq $array[1]) {
($ip, $junk) = split(' ', $array[2], 2);
print LOG "IP: $ip\n";
if ($ip =~ "192.168") {
system("/opt/SUNWut/bin/utswitch -h 192.168.100.12");
}
else {
system("/opt/SUNWut/bin/utswitch -h
sunfire5.engr.colostate.edu");
}
break;
}
}
close(WHO);
close(LOG);
The problem I'm running into is the case with the following two
utwho -c out
lines:
2.0 pseudo.00144f946d3e engr85 192.168.102.208
P8-FS.00144f946d3e
10.0 pseudo.00144fd18d32 engr48 129.82.229.249
P8-FS.00144fd18d32
The space in the beginning of the first utwho output is throwing
my whole
split return in the dumps. Just wonder if there is a better way
in getting
the IP of the DTU you are on when running in kiosk mode? Is the an
environment variable set for the IP of the DTU?
