[SOLVED] IP

zahid · 06-25-2012, 05:15 AM

I just installed Centos 6.2 with desktop environment. During the installation I didn't configure network card like IP, Subnet, Gateway etc. How can I put this thing now and have the internet.

zahid;
So far, you have never posted a follow-up in any of the threads your have started. I encourage you to at least say "thank you", when someone helps you with a question.

As for your question: Somewhere in your menus, there are network settings---but: What is your network? If it's setup for DHCP, then you might not have to do anything. Also, have you checked the CentOS documentation?

Thank you very much. I am really sorry for that I didn't follow the thread due to my lack of knowledge how to use this forum.
For network setting it is not DHCP. I am allowed a connection for internet from our company who rented a bandwidth from a ISP. I didn't have the documentation of Centos 6.2. I want to learn to configure email server, proxy server in linux. Would let me know how should I approach?

there seems to be LOTS of documentation on the CentOS website---maybe start here:
http://wiki.centos.org/HowTos

And google found this:

If there is no DHCP then you will have to know
- what IP address you can set for your server (ex. 192.168.1.123 or 10.0.0.123)
and
- what is the address of your gateway to internet (could be for ex. 192.168.0.1 or 10.0.0.1).

Probably the best would be if you take a look at these settings on a computer you may have nearby which is working and write the numbers down to a paper for future need.

If it has the desktop then you might be able to use a gui screen or have to install a gui manager. yum install NetworkManager
service NetworkManager start

If you are a lazy admin like me you use gui tools. Maybe not lazy just that I like to see stuff.

@pixellany, I am using IPV4. There is a local IP 192.168.0.45, Subnet:255.255.255.0, D Gateway: 192.168.0.126, DNS :8.8.8.8

I am using desktop environment. Now I like to know how to add network setup or how to enable this option in linux.
