There's a linux version of server in SDK, no need to use Wine.
It was a loooong time when I last touched SDK(especially on linux), so don't ask me how to run it :D
If I remember right, jan0s1k made a nice tutorial for running server on linux on the old fonline.ru forum. Sadly old forum is gone :( but ask jan0s1k, he probably can help you.
Ya, it gone even from google cache :<
Anyway in sdk repository (http://xp-dev.com/svn/fonline_sdk/Tools/Runtime/Linux/FOnline_i386.tar.gz) you can find all the packages needed to launch native version of server and client (or even if you don't want to install additional libraries, then you can just use env for it ;) - there are unpacked libraries in this file as well). However as I remember launching server under wine was more efficent (http://forum.newfmc.pl/index.php?topic=317.0) (to be even more you can compile wine with Misiolap patches (http://forum.newfmc.pl/index.php?topic=83.0) - it can help also with displaying ip addresses of the players)
If you want to run native version, I've made init script (http://jan0s1k.fode.eu/foserver.sh) for it (using admin panel and netcat) :
#! /bin/sh

# Provides: FOnlineServer
