Minecraft Technic Pack – Can Factions/Anti-Griefing Tools Be Installed on a Technic Pack Server?

Bukkit is a standalone replacement for minecraft_server.jar and if you want server-side plugins you need to use it. While there isn't a stable release for Minecraft 1.0, after some trial and error I found that build 1493 works and has been running my Minecraft 1.0 world successfully for a few days now.

I can't help you setup Bukkit standalone because I never did that - I installed McMyAdmin. Set it up according to the install directions, go into the control panel and select "Update/Install Bukkit" under About/Updates. It will warn about downgrading - that's OK. Once it has installed bukkit, open the MCMA\Minecraft folder and replace the craftbukkit.jar with build 1493 from the above link. Copy your world in and adjust the server.properties file as needed.

In theory, if you have a working minecraft_server.jar setup running you could just change it to point to craftbukkit.jar.

As for dynamic mapping, the plugin you want is Dynmap.

Yes, any mod that forced players to use a specific texture pack would also require the players to have something locally, to check with the server and see what pack it's using, then download and activate that pack.

In Minecraft 1.3, a minecraft server will have the ability to recommend and provide a download of a texture pack.
