Is it possible to move soldat.ini to another place/rename so noone can check it (for example the server is on a linux machine which has many users and they can see each others home directory) ?

If it is possible, how?

[from linux terminal] chmod 700 soldat.ini

will only allow the file owner to read/write/execute the file

but is it possible to move the soldat.ini? Like replace the soldat.ini content with something else, so it confuses other ppl (they still can view it)

no it's not. not with standard linux commands, at least. i'm sure someone could write a program that could do something like it. like store the normal soldat.ini in another file and then swap them just for a second when the soldatserver is starting. otherwise, no.

Well, you can always move the physical file somewhere else, and then create a symbolic link to it, with the name soldat.ini
This, however, doesn't really fix your problem because the other users will be 'linked' to the physical soldat.ini, when they try to view the symbolic link.

But just do what n00bface told you, CHMOD it. As long as the other users in the server run under another usernames, you have full control who has access to the file by using CHMOD.
