So you’ve got McMyAdmin running a CraftBukkit server and you use the Essentials plugin and all of the sudden, once per minute, you start getting these crazy ping messages:
[31mError: Only in-game players can use ping.[0m
While otherwise annoying (for log/chat review purposes), they don’t really cause any damage.
This happens because McMyAdmin has its own set of commands that it likes to use with the server; things that are not there by default, but that McMyAdmin adds for you. One of the things that it adds is a
/ping command. The problem is that Essentials adds one too, and its
/ping is more picky than the one added by McMyAdmin.
Essentials.jarin an archive viewer (like 7-Zip).
plugin.ymlfile for editing (press F4 in 7-Zip).
ping: description: Pong! usage: / alias: pong
Destroy it! Just chop those lines right out of the file.
