Hi!:

I was using my internet connection I downloaded several progrmas from different sites, One of them sent me to a porno like site where someone catches my ip address or something like that.

I was using Kde then I noticed in the system monitor that one of the daemons of samba reported that "Gustavo" was trying to access unit C, So he doesn't know that I was using linux but I have samba installed and activated where I have several information that I had already moved to a different directory outside from the samba share, but I have noticed that my Internet connection delays a lot.

What can I do?
I know his IP address but he changes it every 15 minutes
What kind of program is he using?
What kind of program can I use to avoid stuff like this?

What can I do?
Unplug your internet connection. Tuck your head between your knees.

I know his IP address but he changes it every 15 minutes
Doesn't matter.

What kind of program is he using?
Again, doesn't matter, but probably a modern version of Windows, maybe even Samba.

What kind of program can I use to avoid stuff like this?
It's called Linux.

OK, seriously . . . Samba uses SMB. Won't go into the full explaination, but an improperly configured Samba server will broadcast 'invitations' to any subnet that it is attached to. If it is running on an interface that is connected to the internet, everyone that happens to share your subnet can see your server without looking too hard. Others can try to gain access without too much trouble, they just have to guess that you might be running a SMB based server. Once they try once and get a permission/password error, they know your there.

You can avoid this problem by restricting the interfaces that Samba is running on and creating an effective firewall. Specifics will vary depending upon your configuration, kernel, etc. If you need further guidance, provide the version of linux you are running and basic internet configuration information.

Stop ALL services you don't need. Configure the firewall as tight as your little sister.
