Use a remote port scanning tool to tell if there are any listening services you don't know about. Hope it's firmware doesn't have any remotely exploitable vulnerabilities that can be deployed over the internet and cannot practically be blocked. You have done everything one can practically do, now just hope :D

This works ok, but it's really slow, slower then using filezilla or a proper FTP client for doing FTP stuff, but if you need to treat it like a normal file system this works. The only way to improve on this is by using a different protocol, which is always advisable as FTP is a rubbish protocol.

Probably too much interference from all the people trying to use wireless causing your network to stop working.

Why do they need hiding? Changing these settings shouldn't have any negative effects...

Upload the files, use a proper version control system for the version-ing (I would recommend git). This does introduce some problems for e.g. removing super old versions could become a bit tricky. Regardless of these problems, I would strongly recommend looking at an existing version control system rather than making your own that's potentially not going to be as good in the long run.

At least you passed the Turing test, non of the bots can get it lol.

Are you sure they weren't logged in as an admin?

Upload it to virus total.

What type of box is it that you need to make transparent?

Obvious troll is obvious. DRM in Linux means Direct Render Manager.

Change registrar.

Perhaps the issue is that individual elements in the arrays are coming from some where else and are been put into the array by reference. This would have the same behavior has previously described. Could this be the case?

objects and arrays have a clone method ;)

I suspect the issue is the same as before, except this time harder to find where it's happening. Basically in Java when you go a = new A(); b = a;, a and b are now the same object, so b.setVal(2). will result in a.getVal() been 2. This applies to arrays and objects. This does not apply to primitives.

char is a Java primitive type, and thus not an actual object. If you where to change it to be a String or some thing that error would go away, and, in fact, String is possibly the type it's meant to be since the length method is used. Admittedly it could be nearly any object, but String length method has meaning (String is an object btw).
