Hi...

I have installed Ubuntu in my desktop PC at home and its conected to internet. Can i access this desktop PC from other places with windows? For example, from my office. If its possible, what are the steps that i should follow. For information, im new user to Linux...so i'll appreciate if you tell in details. Thank you.

You can access your computer remotely. You can get connected by using SSH protocoll which means that you should run at your Linux the SSH service and then connect to it via Putty, http://www.chiark.greenend.org.uk/~sgtatham/putty/, from Windows. You can also have enable the VNC Server at your Linux and by this you can access your computer remotely in GUI from Windows. VNC Viewer can do this, http://www.realvnc.com/

There are numerous way to 'access' your home Linux PC. It would be more useful to know more about what kind of access you want. Typically, people want to access files, and this can be done using ssh/scp/sftp. Ssh will also provide a commandline shell access. Your Windows client will need to have some appropriate software such as a SSH client (someone else has already suggested 'putty', there are others), possibly an X server if you want to run any of the graphical applications on your home Linux PC. Windows networking is built in already, although many ISP's block SMB traffic. For security reasons, there are ways you probably should not access your home PC; telnet, ftp, rsh, all fit into this category.

Be prepared for a few obstacles, such as dynamically assigned IP's that change frequently, firewalls at each end of the connection, and possibly ports being blocked by your ISP. If you are determined enough, there is almost always a way to work around the problems, or find a workable alternative. Usually for free.

you can register a domain for free at www.dyndns.com to keep track of an IP that changes frequently. Personally I also find domain names easier to remember than IP addresses anyhow.
