i did everything on how to set up a bukkit server, but whenever i open it, only i can join. my friends says it says cant reach server! PLEASE HELP!
This belongs under Bukkit Help. On topic, check to make sure you portforward'd properly. Then check if hosting a minecraft server is against your ISP's ToS. Most of the time, your ISP is the one who is blocking it.
Go to http://www.whatsmyip.org/ and copy your static ip and give it to your friends. If it won't work, tell them to add 'ORT' with out the apostrophe.
