Telnet is a useful administrative tool that I believe all of us should be using, not only for logging purposes but due to the extra things it allows us to see such as; disconnect reasons in case of crash chunks, errors occuring in plugins that may need resolved, and banned players attempting to rejoin, as well as the reason they are banned under.
Since the old thread is a little outdated and a little lax on details I'm going to just drop a short tutorial on how to install and use it.
Firstly, download one of these two.
FreedomTelnetClient
ZeroTelnetClient
These two clients are extremely similar and give you the same aforementioned benefits. If there are any major differences between the two that I may need to have accounted for, let me know.
Once the client is downloaded and opened, use the port mc-02.infra.totalfreedom.me:25625 and press connect.
And that's you! You should start seeing commands and messages being sent to the server appearing in the log.
For typing commands, you don't need to type the / beforehand. So instead of typing /eseen shehxlk, you can just type eseen shehxlk and it will output the results. Whatever you type will not be removed from the box upon sending so it's helpful to be familiar with your CTRL + A buttons.
It's also worth noting several commands can only be performed through telnet despite us having permissions to use them.
These include, but may not be limited to:
csay [text], which sends a message into chat like [CONSOLE] shehxlk: text
saconfig add/remove which is self explanatory. There are less reasons to use this one though.
Hopefully this guide will prove helpful to those who need it. If there are any mistakes or anything I've missed, let me or someone with post editing permissions know.
