Change LilyPad fail to authenticate message?

My server is linking with some of my friend's servers (plus a lobby that's a work-in-progress), and LilyPad is working great for that so far. However, when someone tries to connect to a server other than the proxy, they get kicked with a message stating that they failed to authenticate with the LilyPad proxy.

This is normal and makes sense, but I'd like to know if there is a way I could change that message so users will be told the IP they need to connect to.

Currently the proxy is on Ubuntu 12.04.3, but I can edit the files in that or in Windows if needed.

EDIT: Also, just a general question: when players connect to the proxy and then to one of the servers, does their connection continue to flow through the proxy, or is communication exclusively between the player's client and the server it's connected to at that point?

Currently, I do not believe there is a current super easy fix to this. But, it might be a really cool feature to have hard coded in, or at least something in the API. It wouldn't hurt to put this under suggestions.

But, the easiest solution for you would just go change the whats in it, do your person message of the IP you want your users to connect with. Are you running JLilypad or LilypadGO? I believe if you are using Go it would be an easy fix for you to just fix it yourself, and if you are using JLilyPad it shouldn't be that hard for you personally to edit it by looking through a video or a tutorial on youtube. But, if you don't get it, I would be happy to do it for you towards the end of the week when I would get the chance to.

I'm currently testing with JLilyPad, before I get a host for the proxy and lobby servers, but I'll switch to LilyPadGO if possible. What would I need to install so that I can run LilyPadGO?

You would only need Java I believe, to be honest with you I haven't messed around with it yet. But, I have read and watched the idea on how to set it up, they are both really good and I would check out both if I was you. http://www.lilypadmc.org/threads/setting-up-a-golilypad-server-ssh-centos.380/ . It should be pretty easy to transfer it over to you knowledge about computers.

I got LilyPadGO working, but how would I edit the message? Would I need to download the source, edit it, and then compile it?

How much RAM should I expect LilyPadGO (both connect and proxy) to take up per-player? I'm trying to decide if I should ask my buddy if he can host the proxy stuff or if I should get a VPS.

Well I'm definitely not hosting the proxy from home, and if my friend did it, it would be using his own dedicated host. If he doesn't have much of a problem with a 512 MB tops LilyPad proxy, I think that's the route we'll take, and get a 1 GB server for the lobby.

How many players should I expect to fit on a 512 MB proxy, or maybe even a 256 MB proxy, if we try to host both the proxy and the lobby on a 1 GB VPS?

Dang. That's a lot of capability right there.

And, a 1gb server for a hub also seems a little excessive, being that a hub would only be used for teleporting players to other servers, and a general meeting point.

Thanks for the advice; I'll take it into consideration when looking for a place to host the lobby.

You can host your lobby and your proxy on the same server. Remember, the only IP that matters is the Proxy, so you can run the lobby on another port.

I have one last important question -- is there a way to allow someone to connect to a server directly and still authenticate with the proxy, e.g. player A could connect to servers A, B, or C, and still authenticate with the proxy?

But what about this?

Currently, or at least in JLP, it was hard coded into it. I can fork the repo and give you a changed message if you'd like. @TheShadbusher

As Coelho said, its not the best thing for your players to no the backend IP in the first place. So, a quick suggestion, it might be best if you changed your IP's the next time you pay the bill, and lower your current servers down to the smallest server size possible, and just set the IP of your server in the MOTD, and the kick message.
