Hi!
I would recommend using Bukkit RemoteToolkit, because I've used that too and it works fine. Just install the plugin and setup the console connection with a small program named putty
RemoteToolkit: [ADMN] RemoteToolkit [R10 a13] - Restarts + crash detection + auto saves + remote console! [1.2.5] | Bukkit Forums
Putty: PuTTY Download Page
I have never tried this plugin RemoteBukkit - Bukkit, but it might also work as described.
Hope this helps you!
