Hello,
This is a problem of Concurrent Programming that I solved in a test:
The parking lot have 30 spots. Since the parking lot have spots, it doesn’t have priority. When it is full, starts to make a line. Professors have the highest priority, Employees have the Medium priority, and then it comes the students. Use Java to simulate 10 Professors, 15 employees, 30 students.

Hello,
If you want to UPDATE your tunnelbroker end point, you can use this: http://ipv4.tunnelbroker.net/ipv4_end.php
There are the format that you have to use. In /etc/rc.local file I add this line to get my IPADDRESS:
IP=`ifconfig eth0 | grep “inet addr” | cut -d : -f 2 | cut -d B -f 1 | sed ‘s/^ *//;s/ *$//’`
And after this one to update the ENDPOINT
wget https://ipv4.tunnelbroker.net/ipv4_end.php?ipv4b=$IP&pass=senha&user_id=USERID&tunnel_id=TUNNELID
Best Regards,
