Hi,

check you /etc/hosts file

155.x.x.48 your_host your_host.dot.com loghost
127.0.0.1 localhost loopback

check your /etc/rc.config.d/netconf

LOOPBACK_ADDRESS=127.0.0.1

Check for the entry /etc/hosts

127.0.0.1 localhost loopback

delete and retype the line in case of control/junk characters.

Hi,

#netstat -rn

o/p should show your default gateway.

if the default gateway is functioning but still unable to telent to localhost check the /etc/nsswitch.conf file (if file not there copy nisswitch.nis to nsswitch.conf)
edit the nsswitch.conf file,
make sure line containing hosts is like
hosts: file dns

Do a "nslookup localhost", what does it return?

Can you post your /etc/nsswitch.conf and /etc/resolv.conf?

What version of BIND are you running? You should be running 9.2: http://www.software.hp.com/portal/swdepot/displayProductInfo.do?productNumber=BIND9.2

There're no nsswitch.conf and resolv.conf in the system. And only have one unix machine.
Thanks.

hi,

could u create the file, /etc/nsswitch.conf which will try to resolve the host?

# cd /etc
# vi nsswitch.conf

hosts: files dns [NOTFOUND=return] nis [NOTFOUND=return]

# nslookup
> localhost
what is the output now?

regards.

Hi,

Looks like your loopback didn't get initialized. You are basically routes to localhost in your 'netstat -rn'.

Try

ifconfig lo0 127.0.0.1 up

and see if it works.

Or run /sbin/init.d/net.init start
