I have access to the mohaa directory in general as well, though I cannot remove or rename the mohaa.exe or mohaa_server.exe.
Though when I wanted to add a different mohaa.exe & mohaa_server.exe (which was protected against rcon flood & BOF) I just send an email to the host, and they changed the files for me
I only have access to the main files.
and i know of experience that with some server providers (for instance clanhost.nl) you only have access to the files YOU put in it and the server.cfg so you can't see the .pk3 etc
full access on windows servers, linux server cannot change .so, have to send it ticket to do so. will eventually try to get one more server of each with full access to test and help script any mods necessary to mohaa.
I dont have access to .exe or .dll files, but i can see the base folder, but have been waiting for 2 days for access to it, or any respond from my hoster
