finally got this working, here is the issue I got and how I fixed it Ubuntu 10.4 stable, apache 2, php 5 downloading the install.sh in the /var/www/spacebukkit, and ran it (no issue) I already had php5-cli installed Then to continu on the web, I was stuck at step 3 (blank page) that was because php-curl wasn't install (sudo apt-get install php5-curl) and also my web folder didn't have the "write" access (chmod -R 775 /var/www/spacebukkit did the trick) I saw that by looking at my /var/log/apache2/error.log. That was for the step 3 problem ,after that I had the issue with step 4 (server can't be reached) First thing I found was that the salt is not something you put randomly, but it's actually something that is written into the configuration.yml that is located into the SpaceModule in my craftbukkit folder (my craftbukkit folder is located at /opt/craftbukkit, so the folder was at /opt/craftbukkit/SpaceModule) in that file you will see the salt (I actually found that in the comment) Then I made sure my firewall was fowarding the port 2011 and 2012 to the web. now it work! nice job! my donation is on the go.
