When I first installed redhat 9.0. I would be logged at
root@localhost .Now it has changed to root@alopa. And now because of this iget an error message that says something like cannot connect to internet for alopa. Gnome will not operate properly.What does this mean and how can I change this to the original way @localhost.And what is alopa.

well it seems like you changed your hostname, check out this and just for spite try changing it back to localhost and see if it helps...

DrOzz,
I tried what you suggested in the link but it still comes up to alopa.The login screen saids welcome to alopa.Then I put in my login name and then password and then the error message come up and saids.Could not look up internet address for alopa.This will prevent gnome from operating correctly.It maybe possible to correct the problem by adding alopa to the file /etc/hosts.Well i did that and the problem diseapered.But as it's booting up when it comes to starting sendmail it holds there for about three minutes and then continues.It started doing this after i fixed the alopa file.If i change the file back to localhost starting sendmail goes on thru. But of course the error pops back up.also where did alopa come from.One day it was localhost at the login screen then the next alopa appeared.
help much appreciated

so do you mean that in /etc/hosts you have localhost and in /etc/sysconfig/network you have alopa ? also i have no idea why it says alopa, someone had to of changed it...

Very easy fix for this error.

In /etc/hosts file where is shows the line which is tells you not to remove it. at the end of this line replace 'localhost' with your computer name or whichever name it states in the error dialogue box.

i.e My original line read.........127.0.0.1 localhost.localdomain localhost

Now my line reads..............127.0.0.1 localhost.localdomain N1Y3T6]

Hope this helps.
