| Hello.
My linux DEBIAN LENNY x64 not ping localhost and local IP.
Ping external is Ok.
External servers ping my server normal.
I no have firewall in this server.
Sugestion?

| More info would be helpful...you can't ping "localhost", did you try 127.0.0.1?
You may not have the entry in your hosts file.
When you say "Pink external is OK", you mean you can ping things FROM the server, or you can ping the server FROM the 'net?
If you just can't ping localhost, check your /etc/hosts file and make sure the line
127.0.0.1 localhost
is there.

| Try adding the following lines in the /etc/hosts file.
127.0.0.1 localhost

| It wouldnt be a host files issue, if he is not able to ping 127.0.0.1.
Does it give you a permission denied error?
What is the output of:

| Correct...it would also be good to actually see the results of a ping.
Do you actually have a loopback interface setup? (ifcfg-lo) and is it up?
Also, check your sysctl.conf and see if you have
net.ipv4.icmp_echo_ignore_all=0
If you are not running as root while pinging, it may be Selinux....is that set to enforcing?

| Ah, completely forgot about selinux. Good call. But I'd imagine he wouldnt be able to ping ANYTHING if that was the case. I'm more weighing towards a default iptables policy thats blocking ICMP.

| Is this a physical or virtual server?
What is the output of 'cat /etc/hosts' command?
