My IP is not persist


Hi,

I had the system assigned with DHCP, The thing is even though ip is showing, it is taking as localhost.

I used following commands to check:

ifconfig------------> ip is there.
hostname -----------> hostname is showing as local host.
hostname -i ---------> ip is showing as 127.0.0.1


i then checked the file vi /etc/sysconfig/network-scripts file
i cant find any change or problem.


so, please help me in resolving this issue.

regards
praveen.

127.0.0.1 is the internal IP
the IP in your ifconfig is the external
what is the problem?

That's because 127.0.0.1 is bound to the hostname in /etc/hosts

This should not be a problem. What issue are you having?

could you possibly post following
1. ifconfig results
2. /etc/sysconfig/network-scripts file

and of course not to miss out the problem.

do you use this computer to go online and are unable to ?

So what is the issue or problem you are experiencing? Your post really does not ask a question or describe a problem. I do not understand "My IP is not persist"

What distribution/version are you running? Some like Fedora for example set the hostname as localhost by default. However, localhost is also the name of the local loopback adapter lo i.e 127.0.0.1. This is normal.

The output of the ifconfig -a command should show all network interfaces. Post the results. If dhcp is working you should see information for eth0 with a assigned IP address. If an IP address is not assigned then dhcp is not working or you may have other network problems. If all you see is information for lo then your network adapter may not be configured correctly.

ip is not stable in my system

Hi michael,


The problem is ip is not be stable in my system.
since when i check for ifconfig it showing 10.112.73.235
when i check for hostname -i it is showing the local host ip(127.0.0.1)
like that.

But for me I want the hostname -i should be 10.112.73.235.

hostname -i is supposed to be 127.0.0.1 and as was mentioned to change it change 127.0.0.1 in /etc/hosts to the ip you want though that will probably break a few things...but hey its your choice.

What you have described is the correct setup of your system with a persistent, stable IP. There is nothing wrong with it.

ifconfig is showing you the IP of your network device.
hostname -i is showing you the IP of the loopback interface.
these are different things, they are supposed to have different IPs.

Why would you want that? This will break your system.

What are you hoping that this will achieve?
