default time in Solaris 8 for time-wait

Ok, heres the situation. We use Solaris 8 and sometimes users who are logged into our system restart their pc's without shutting down the application that attached to our unix backend. I netstat and I get time-waits for the users.
My question is how long before the time-wait ends and the user can log back in?

Try with this ...

In order to close shortly your connections you need
to modify several defaults, for example:

ndd -set /dev/tcp tcp_time_wait_interval 60000

ndd -set /dev/arp tcp_time_wait_interval 60000

Note: use man ndd to look one by one the parameters
of the command

ndd -get /dev/tcp \?

Note: Don't looks like a Time Zone Problem.

I give you an example for tracking connections to the port 80 in Solaris:

wdate=`date +"%Y%m%d"`
whour=`date +"%H:%M"`

netstat -na |grep -v -i listen |tee -a /tmp/"$wdate"_port80.tmp |/usr/xpg4/bin/awk '{ if ( NF == 7 && substr($1,length($1)-1,2) == 80 ){v[$7]++; cont++} }END{ for (i in v) {print i": " v[i]";" } print " Total: "cont " " }' |while read lin

echo "$wdate ; $whour ; $wline" >> $LOG

cat /tmp/"$wdate"_port80.tmp |/usr/xpg4/bin/awk '{ if ( NF == 7 && substr($1,length($1)-1,2) == 80 ){print $1,$2,$7} }' | /usr/xpg4/bin/awk 'BEGIN{FS="."}{print $1"."$2"."$3"."$4"\t"substr($5,length($5)-2,3)"."$6"."$7"."$8"\t" $9}' | /usr/xpg4/bin/awk '{ d[$1]++ ; o[$1" ;"$2]++ ; f[$1" ;"$2" ;"$4]++ }END{ for (i in d){ print i"; All_ips ; Total ; "d[i]} for (j in o){print j " ;Subtotal; " o[j]} for (k in f){print k " ; " f[k]} }' |sort |while read wline
echo "$wdate ; $whour ; $wline" >> $LOG2
rm /tmp/"$wdate"_port80.tmp
