Hi:
I am having a rather confusing issue regarding my loopback address. The
computer has a 10.x.x.x address on its eth0 interface which is connected
to a Linksys router's LAN port
The ifconfig command shows that my loopback address is 127.0.0.1. My
DNS resolver shows that this is still the case. The /etc/host files
shows that the localhost is 127.0.0.1.
nslookup localhost and nslookup localhost.localdomain both show up as
127.0.0.1.
however when I attempt to ping typing this command
ping localhost
It shows that it is pinging my border router's WAN IP address instead of
the loopback address. I can verify that there is no IP masqurading
going on as there is no such entry in the iptables.
Any ideas as to what might be going on here?
There are a huge number of possibilities. Doing an 'strace' on the ping
might help. For example:
You might be in the domain 'mydomain.com' and ping might be trying
'localhost.mydomain.com' first.
You might be using 'nscd' and it might have some other value for
'localhost' stuck in its cache.
Your resolver may be configured to use something else before /etc/host
or DNS.
