Installing CentOS 64 bit on window machine

Hello Friends

I am new to LinuxQuestions.org forum. I want to build 64 bit linux machine with centOS distribution. I have a machine with windows 7 which I want to clean and instal centOS on it. Can any one suggest me where I can find centOS 64 bit OS and some instruction how to clean and download centOS.

Thanks and highly appreciate your help.

Thanks for your quick reply and highly appreciated. I will follow the procedure as given.

how about the cent os web site ??????
http://centos.org/
at the top of the page is a link called " Download"
click "mirrors" and the "http" link for say " Arctic Network Mirrors"
http://centos.arcticnetwork.ca/
for the current Centos 6.3 64 bit
http://centos.arcticnetwork.ca/6.3/isos/x86_64/

as to the install guide
cent is a rebiuld of RHEL6.3
cent uses the red hat documentation
https://access.redhat.com/knowledge/...erprise_Linux/
-- the install guide---
https://access.redhat.com/knowledge/...ide/index.html

Thanks John for your valuable input. Appreciated.

Hello Friends

I have successfully installed CentOS6.3 into my machine. I am trying to access this machine through my Laptop using putty. But it is not working. Before that, I set the following in etc/init.d.
1. First restarted init.d # ./sshd restart and then entered iptables -F and uncommented port 22 in the sshd_config file. Remember I am in the same LAN.

Any suggestion please. Your help is highly appreciated.

Thanks

Server: Show the content of /etc/ssh/sshd_confg and /etc/sysconfig/iptables.
Client: Also, exactly what error msgs did you get.
Server: check /var/log/messages, /var/log/secure log files

Thanks for your quick reply. When I try to connect to my linux machine through my laptop which has window 7 by using PUTTY. I am getting 'Network error: permission denied'.

Can you please suggest me if I miss anything during my connection through putty?

Thanks

You need to answer my other 2 qns about the server setup.

Hello

On the server side, I have following in the file.

On serverside - sshd_config file has following info.
port 22 (uncommented)
#AddressFamily any
#ListenAddress 0.0.0.0
#ListenAddress ::
#activation of protocol 1
Protocol 2 (uncommented)

In the /etc/sysconfig/iptables file:
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state -- state ESTABLISHED, RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -j REJECT --reject with icmp-host-prohibited
COMMIT

Thanks for your help. Appreciated.

Linux is normally case sensitive, so try 'Port 22' & restart sshd service.
What about the logfiles?

Hello Chris,

Here is the other details.

I didn't change anything on port 22. It is as it. I just uncomment it.
Here are other two files.

Hello Chris

Do you get a chance to take a look at log which I sent yesterday. Thanks for your valuable time.

Ensure ssh is listening, then do (on Linux)

Code:

tail -f /var/log/secure

and try to log in. You should see new msgs appearing in the log when you do this.

I tried this, but I still get the same error message when I try to remote by using PUTTY.
Thanks

1. Did any msgs appear in the log?

2. try turning off iptables

Code:

service iptables stop

and try logging in again. DO check the logfile /var/log/secure

3. how are the 2 machines connected: direct, via a switch, via a router, via a hub?

Hi Chris

Thanks for your help. It is working now. Appreciated your time.

here the problem does not seem to be on "linux" box. just for a moment, try
to disable the firewall on your "windows 7" machine.

then retry to connect.

Hello Friends

I just realized that I installed 'antivirus' software Norton in my window machine. That may be one of the reason I could not able to connect. Even I could not to connect to work after I installed this machine. Today I uninstalled this and tried. It is working perfect.

Thanks everyone for all you valuable inputs.
Highly appreciated.
