Troubleshooting in ACM-ICPC Contest

i’ve participated in many contests as organizer, specifically in the technical stuff which is mainly two portions

• The IDE which is mainly “eclipse“
• The contest communication tool which can’t be except “pc2″

and in the last contest i’ve participated in it’s technical preparations i faced a number of troubles

lets take them one by one

1.Teams don’t connect to the Server which is a Linux Machine

• Solution : before you open the server edit the “pc2server” file and edit this line
• java -Djava.security.policy=policy.ini $PC2CN $*
• to be
• java -Djava.rmi.server.hostname=”10.106.0.35″ -Djava.security.policy=policy.ini $PC2CN $*
• of course change the ip according to your server ip

and make this edit in all the executables you will run {team, board, judge…..}
