Question ID: 509083
I am looking for a free program which will let me access my computer
remotely and transfer files.. I don`t need to see my desktop or
control my mouse, I can even work with commands and directories.. All
I need is to reach my files remotely whenever I want for free.!
In addition, I have a bigger problem than that.. I am behind the
router of my university.! I contacted them and apparently there is no
port forwarding oppurtunity.. They told me to make a VPN connection
with the university server and I did it.. Before the VPN connection I
wasn`t even able to access myself using my public IP and now I can..
But that`s the only difference.. I still can`t access my computer
remotely.. The only program that worked is LogMeIn but its free
version doesn`t include file transfer feature.. I want to know how it
manages to access my computer and if I can use the same technic to
gain access or if there is another way of doing it.. There must be a
way.! If you can help me I will really appreciate....
I should include that my university will not help me more than they did until now..
Just a program name is well enough for me for the first part of my
question and if there is no free program, don`t be bothered.. Second
part is my main problem.!

If you can access your computer by IP address, there are several
possibilities. One of the simplest is to run an FTP server on your
machine, which you access remotely with an FTP client. I assume you're
running Windows?

I can not access my computer by IP address, that`s the problem.. I am
sorry if I confused you by saying "access myself".. I meant when I
open Internet Explorer on the PC `I want to access` and enter my
public IP and a open port I am able to enter my computer itself.. But
when I try to connect my computer from another compoter it  doesn`t
work..
I had tried using FTP clients but I couldn`t manage it.. I entered my
IP address as the host address but it didn`t work.. Do I need to
install a FTP server?! What is that?!
Yes I am using Windows XP Home Edition.. But I would like to know how
to access computers with other operating systems if it is different.!

The IP address itself is recognized, so that's good. The reason you
can't yet log in remotely is that you don't have a server running on
your machine that will accept connections. But it's not hard to
install and run your own FTP server, which lets you transfer files to
and from any machine worldwide. Under Windows, you will at a minimum
be able to use the ftp command in the DOS shell, but graphical ftp
clients are typically available as well.

Anyway, the first step is to download and install an FTP server on
your machine, then start running the server and make a user account on
it.

I suggest you try out the Cerberus FTP server.

http://www.cerberusftp.com/download.htm#download

I don't know exactly what the installation wizard does, but it may
well give you the option to set up an FTP account in advance. If it
doesn't, try running the server after installation and see if you can
work out how to make a new account. Once you have the server running
and an account set up, all you need to know is how to use an FTP
client on a remote machine. Get started and report back to me!

Let me just clarify a few things. A server is a program running on
your machine. Some people use the word "server" in reference to a
computer that's dedicated to running one or more servers for many
outside users. But strictly speaking, a server is a piece of software.

And you don't have to worry about operating-system compatibility,
since FTP is a platform-independent universal standard. It's designed
precisely for the purpose of communicating between different machines
that have nothing in common but an understanding of the FTP protocol,
which is provided by the server or the client.

I can connect to myself.. I have tried using FTP and
RemotelyAnywhere.. They work when I try to connect to myself from the
same computer.. But I told my friend to try to connect to my computer
and both didn`t work, neither FTP nor RemotelyAnywhere.. I turned back
to the beginning.. The only difference is now I can connect myself
using FTP client, but again not remotely.! There must be a problem
about my IP address, it doesn`t seem to be accessible.. I even tried
using a Trojan, opening a port and trying to connect to myself.. It
was the same thing.. I could connect to myself but my friend
couldn`t.!

Using your VPN, have you shared a folder? Meaning, have you given
access to anything on your computer so that a connection can be made
to it? If VPN is setup and working, you should be able to share a
folder on your C:\ drive, view that folder when you are logged in, and
get/put files in that folder. You shouldn't need anything else other
than VPN working to do this.

I didn`t really understand what you mean.. Do you mean entering the
properties of my drives(like c:) and enabling sharing?! What would
that change?! And what do you mean by logging in?! Logging in where?!
The VPN is between me and the university server.. The remote computer
should access my computer using an internet browser, an ftp client or
whatever, not using VPN connection.. The problem is when I try to
access my computer using my IP and the open port, it seems like either
the IP is wrong or the port is not open.!
If I understood right, you thought that the VPN is between my computer
and the remote computer.. It is not.! And this is not what I want
because I need to be able to access my computer from any computer
while I am away..

Hi, 

After you make the VPN connection, could you ping your system by IP address?

If not, you may be out of luck because certain VPN solution only allow
you to access cerain part of the network.

I found a web site to ping IP addresses, wrote my IP and pressed
`ping`.. Result: `11 packets sent, none received. Ping returned an
error.`
I don`t know what these and what you said mean.. But direct connection
must be possible somehow.!

If I understood this correctly (which is not guaranteed!), you may
have a router (a) between the computer with the FTP server and (b) the
internet.  If that is so, you have to forward the ports through the
router to the PC that has the FTP server.  Any firewalls on the PC
should also let that port through.

Also, some VPN clients will block (firewall) ports on the machine they
run on (Checkpoint SecureClient, for instance).  If you are running
that on the machine with the FTP server, you may have to disable the
security policy before it will stop blocking those ports.

Yeah.. That is the exact case and also that`s why I have asked that
question.. I am behind the router of my university and they told me
that there is no port forwarding oppurtunity.! They told me to try
making a VPN connection with the university server and gave me the
instructions to do it.. I did it and the only thing changed is my
public IP.. It used to be a static IP now it is dynamic.. But still my
computer is not remotely accessible.!
I don`t have any program blocking my ports.. 
It doesn`t seem possible in that situation but using LogMeIn I can
access my computer remotely.. I want to know how it manages to do
that.! If it can, there must be a way without forwarding a port of the
router..
