ping localhost fails

[v_8]

In my RHL 8.0, I can "ping 127.0.0.1" but not "ping localhost". Replies with an "unknown host" error.

In a shell enter neat, or redhat-config-network, or hit hat menur / system tools /control of network peripherical (could be slightly different name, I'm translating from my box on french menus), select your NIC, configure, and on the host section, check that you should have a line with '127.0.0.7 localhost.localdomain localhost' (being IP name Alias sections).
This effect is due to the fact that your IP is not linked to you machine short name.
Re-start network.

Hi,

Edit /etc/hosts
127.0.0.1 localhost localhost.localdomain

Save the file.

#ping localhost

that's it.

Hello!

Check the permisions of your /etc/hosts file
and see that you have read permisions on it.
If it's OK check that you have a line in the file /etc/hosts : 127.0.0.1 localhost
if not add it, then it should work.
