Unable to ping localhost

Hi all,

I have gone through many posts related to this issue,but my issue wasn't resolved hence creating new thread.

I am unable to ping localhost.

Code:
ping localhost

tries to ping localhost which is defined in DNS.

My /etc/hosts has entry for localhost as

Code:
127.0.0.1 loopback localhost

.

My /etc/netsvc.conf has
Code:
hosts = local, bind

.

Still i am not able to ping localhost . Please help.

Just a first thought. Is the lo interface up?

Hi Scott,

I am not aware of command to check the status of loopback service.

Please let me know the command, i will share the results.

Try with:
Code:
# ifconfig lo | grep RUNNING
UP LOOPBACK RUNNING MTU:16436 Metric:1

A couple of other questions. Is this a new problem? Are you running a firewall (i.e. iptables)?

PFB Output
Code:
XXXXXXX:/etc->ifconfig lo | grep RUNNING
interface lo is invalid

maybe this issue was since sometime, we came across this when using Datastage application as localhost ping is not working.

And we are not running a firewall for this server.

just to be sure: is netsvc.conf containing:

Code:
hosts = local, bind

I do not know for sure, but I have always removed any spaces. And, if you are not using IPv6 you might be happier with

Code:
hosts=local4,bind4
