Newbie Login Error HELP!

Ro_laids · 04-16-2003, 10:10 PM

Hey guys,
Here's the deal I'm so new to Linux Im lucky I got this far. I'm using Red Hat 8.0 personal. I've installed the OS everything is loaded nic card sound card vid card etc. everything even works. However, when I try to login in to Linux I get this error " Could not look up internet address for (my Computer name). This will prevent GNOME from operating correctly. It may be possible to correct the problem by adding (my computer name) to the file /etc/hosts."
"Then I get the options to login anyways or Try again. "

How can I fix this issue?
Remember i'm really new to Linux so please be as descriptive as possible. I've tried to access etc/host but I'm to far lost to fix the problem.

I had this exact same problem and was able to solve it by running /sbin/ifconfig to show my IP address, then used vi to add the line-- "xxxxx(my ip address) yyyy(my hostname) below the already existing line for localhost loopback address of 127.0.0.1 -- then just log out and in again and it works.

Thanks for the reply! One more question though. When in (VI) what do I do then? I'm really knew to vi. I dont know what to type in vi... Call me an idiot if you will, but I'm still learning this whole Linux thing and to tell you the truth I'm actually having fun doing it.

When you first start vi press [i] to enter insert mode. Then just type in the line you need, then press [esc], then press [:], then type wq[enter] to save the file.

x1-6-00-50-bf-1e-f6-02# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost

This is what etc/hosts looks like after I start messing with VI. LOL Im loving this.... Ok I realize this isnt right. How do I fix the very top line where I tried to insert my computer info? And also Am I even in the rigth spot to fix the login error that Im having? If so I erally dont understand what I have to type "the actual line that will fix my problem" I know I have to use my ip addy and computer name but what format do I use to enter it in VI. Im so lost... HA gotta love us newbies.... Ill keeptryin g stuff maybe Ill figure it out on my own. That would be good for me. Help plz guys!!!

Well, I was just trying to help you use vim, and I don't really know the answer to your problem (I don't use gnome), but I believe jackopa suggested adding this line:

Code:

00.00.00.00 mycomputer

where '00.00.00.00' is your ip address, and 'mycomputer' is your hostname. I get the impression however, that you have not set your hostname yet. I would do so using the hostname command ie:

Code:

hostname mycomputer

Then edit your /etc/hosts file so it looks like:

Code:

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain mycomputer

This may do the trick for you, else, follow jackopa's advice.

THANKS A MILLION GUYS!!!!!! We got it working beautifully. I took everyones advice here so thanks to you all. I feel like a kid in a candy store. HA I ended up trying to edit etc/hosts using VI but I think I need to read some more on the whole vi thing I can get around in there but not real well give me some more time and I think I will grasp it with ease. I ended up editing using the gnome network configuration tool. (easy way) I used my ip addy and host name in the editing and logged out and then back in and presto problem GONE! WOW that was really easy thanks.....
