Installing and configuring FUNC

For  my class project with Jason Van we are installing FUNC on a group of computers. FUNC is a program that is used for broadcasting network commands to a bunch of computers (minions) just from one location (master).

First I installed FUNC on the master (chili) by using yum install func. After that all we had to do for the master was set the service to run on level 3,4,5 (chkconfig --level 345 certmaster on) and starting it (service certmaster start).

Then came the minion installs of Romania. Again I used yum install func to install the service and then I configure the "/etc/certmaster/minion" file to display the correct certmaster name (chile.proximity.on.ca). Enabled the service and started exactly the same way as the master. On the master system  I ran "certmaster --list" and then ran "certmaster-ca --sign romania.proximity.on.ca".

I did run into a few troubles with iptables not immediately letting the default port through and I had to remove the IPv6 address line in the /etc/hosts file because the certmaster kept listing romania incorrectly.
