That's is the question.. how can i jail a user in a certain folder so that he can create files like images but can no go up using the command cd .. or see other folders outside?
Thanks.
Read about chroot http://linux.die.net/man/1/chroot
You can even create a minimal environment for the user
Alternatively just use file permissions so that the user is only able to see what the user should be able to.

I have a Ubuntu 12.04 machine that I can only access using SSH. On this machine I have two users and I want to limit the access to certain files to one of these users.
Basically I want that user to be able to access only its home directory and nothing more. I know that by removing the rx permissions to other home directories for others is one option but I wanted to know if there is another way, a configuration file where I can tell that my user can only have access to that folder.
Thanks.
chrooted jail is the answer.

Is there any way that i can find the most frequently applications used by a user in Linux? In Windows you can read this information from registry.
Make sure that accounting is turned on:
chkconfig psacct on && /etc/init.d/psacct start
...and then get summary info with sa. Look at examples here or here.
My own experience is that the most frequent command in the account is a shell.

Lets say I want to access a windows file C:\Users\Documents\Myfolder\whatever.txt on Ubuntu. Is there any command existing that I can open whatever.txt on Ubuntu ? Also What will be the format of path ?
Your C partition should be mounted somewhere in /media. The rest of the path is pretty straightforward.

I have a regular username on a linux machine. I also have the root privilege. Today I found my username was deleted. That is, if I logged in as root and then ran
su myusername
The systems said "myusername" does not exist. I checked file /etc/passwd and "myusername" was not there.
My question is, is there anyway to find out who deleted "myusername"?
You might try something like this:
grep "deluser" /home/*/.bash_history /root/.bash_history

Suppose I'm using the write command to send messages to another host on the server. Can the root user or any other user get to know that we are interacting?
This can easily be done by any user that can capture packets on the interface (including root) and any intermediary devices. Moreover, root could in theory install additional mechanisms to hijack/inspect traffic.
