Ubuntu server permissions issue

[Tabasco]

Examine your output, there are some show-stopping errors right there:
./EQEmuLoginServer: No such file or directory
./world: No such file or directory

I'm not especially familiar the guide, but in my server directory I set up symlinks to the necessary binaries. You could also just copy them, but you would need to do that any time you recompiled.

You need zone, world, eqlaunch, queryserv, ucs, and EQEmuLoginServer if you're running your own login server.
