Software engineer on the first 64 bits Unix (Cray).
System & network admin. on top of a > 1000 Mac.
30 years experience on top of Unix (and internals).
Chief Information Security Officer.

    Security through obscurity: 
    A father wishing to avoid his son to taste his bottle of vodka
    decided to hide it.
    He transferred it within a bottle of plain water with no label on it
    and put it in the fridge among the other bottles of water.
    On the evening coming back from his work he found his son dead
    on the floor of the kitchen. A broken glass on the ground,
    an empty bottle of water and an orange sirup bottle stand still
    on the work plan…

I advise you to test Disk Arbitrator: apple.stackexchange.com/a/39360/22003 . This will protect you against Spotlight, anti-viruses and attacks.

comment I want to allow a specific port but still keep my firewall active. OS X 10.8
@Jenelle: "The builtin firewall used by OS X is ipfw". This was true on 10.6. On 10.8, ipfw is still usable, but the firewall is now an application one. See ps ax | egrep '[ /](PID|socket)' and /var/log/appfirewall.log.

Your question is rather hard to read. Please try to put the dots and returns at end of sentences. Use "`" to clearly separate reserved words or command lines from plain english.

I'm really sorry but this server is unusable. After opening me more than 10 new windows of commercial advertising (most of them with about 10 hidden trackers) and another one to install a software, I threw in the towel :(.

This answer is risky. The .Trash doesn't get the default ACL it has by default. Moreover on a corrupted FS it won't work. It's easier to say this now that we know the FS is damaged :).

@klanomath: I was able to read the files dropped on imgur.com, pastebin.com, but not the one on zippyshare.com (opensnoop log). Does the error message "No such file or directory" disappear at the end of the download? Is your FS corrupted after the end of the download (Illegal name)?

The FS of Sami is clearly damaged. But there is something wrong around this file name. @klanomath, could you run your 1st ls with the corrective unset LANG immediatly after the download of the suspicious file or disk image. A running opensnoop would be interesting.

@klanomath: I forget a key point. If your LANG=en_US.UTF-8, then any char is printable and the -B isn't of much help. To use it efficiently one should enter unset LANG ; ls -aBeil.
