Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I am quite new to linux and I have to ask for some help here.
Recently, I browse into my home directory and noticed there were some
suspicious hidden files there. One such file is .user60.db. I think I might
be hacked by an intruder.
I have removed the said file with bash command rm .user60.db since then.
Would like to receive some comments and perhaps some good news!
Just for security, check you ports. Download Nmap http://www.insecure.org/nmap/ (If you already dont have it). Its an excellent tool. Check for your ports like this:
nmap localhost
It will give you a list of open ports..close unnecessary ports.
DrOzz,
Thank you for the GOOD NEWS and perhaps the bad news - because I have
already removed the file .user60.db from my home directory due to security
concern.
I did have an html editor BLUE FISH installed in my system. And this .user60.db file also show up in the home directories of the user accounts.
Thanks again.

p.s. sorry for the late response due to difficulty in making the post reply page
to work because I didn't set up cookies correctly.
i don't quite understand what you getting at?
lets just put it this way:
so, by convention UID's of 499 (depending on distro it may be 500) or less are special system UID's, and roots' UID is 0, Regular users get UID's starting at 500, (again, depending on distro it may start at 501)
Not sure I follow your question/reply joseph? You want to know if it's ok to open all your ports on a server? Not the greatest idea really... Can you clarify what you mean?

If ever you are in doubt of whether you are being hacked or not, take the machine off line immediately. That's the first thing to do, after that it's all details, but that's the single most important thing to do, cut the cord.
After that, follow unSpawns many threads on this, just do a search for "being hacked" or check out the main sticky thread in the Security section.
i mean, i just wanna know about what service is opened, i do not have any other meaning, maybe i can giving him which port need to be opened and which service need more attention.
Oh, I see! So he could post up something like:
ps aux
And give us a bit of info about what he's wanting to run/running so we can guide him on what to close up...
