My computer was running without any problem but this situation is not last long. Someone(ISP provide) has remote access to my pc using ssh and configure my xorg file and i cannot login to GUI mode anymore. I have search the file where the file located but unfortunately cannot find it.

My error message is as below:

My default terminal name is nicholas_tse@dhcppd0 and now change to I have no name!@localhost .

How to change it back to default ?

In the bar at the top is the same but in the terminal there is I have no name!

I hope someone can help me in this problem.

By the way, how to secure my fedora core 6. I have iptables and iptables6. I also have shorewall, squid and snort but i don't know how to configure.

Your help is greatlt appreciated by me and others.

Thanks for our help.

Did that guy take a backup?
The Xorg config file is /etc/X11/xorg.conf.

If not, you can try to let X11 generate a new one:
Xorg -configure

After that you have a config file (do this as root).
Then test with Xorg -config=/location-to-the-new-config

If it works, copy it to /etc/X11/xorg.conf

This works if you use Xorg not XFree.

If someone has compromised your system and has control I would think that a reinstall is in order.
If the person is someone you know and trust you may be able to straighten out the mess,if not reinstall.

I have GUI mode but when the screen display the login username. The username i entered is not recognized by the system. The password still the same. Why the X config is related to username and passwd file ? I don't understand. Please for give my stupidness. Thanks for your help. My problem is not about grpahics or display. My problem is the username cannot recognized.

I try to create another user and the result still the same.


I have log in to runlevel 3 and when i login i get this message:

I have checked the /etc/passwd and /etc/login.defs but seems nothing went wrong.

Below is my /etc/passwd file:

nicholas_tse:x:500:500:unknown:/home/nicholas_tse:/bin/bash

Your help is greatly appreciated by me and others.

Are the permissions of /etc/passwd and /etc/group as follows?
-rw-r--r-- root root

Maybe you should be searching in the direction of SE Linux.

I will have a check. By the way, i can login in run level 3 but the name of user name have changed to I have no name. My default name is nicholas_tse - "nicholas_tse@dhcppo". I would like to change back to default.

I cannot login in GUI mode.


Thanks for your opinion.

Any other suggestions and recommendations. Please help me. I was suffered without fedora core 6. My life is fated.

I think i should beg for any help.

Thanks for your help.

Help me please.

Help me please.

As you see there is no one who can help you here.
Or they don't want to help you.

I think you should try asking on IRC. (freenode network)

I'm sorry to hear about your problems. It sounds like your box was compromised. You should do a clean install and make sure that you have the firewall up with no open ports.

Thanks for your suggestion.

How do you know his system has been compromised?
I worked alot with systems that had absolutely NO firewall.
Without any problem.

There is probably something else going on.

I strongly suggest you ask on IRC for someone to help you.

Whatever works for you then.
