look i have 3 ip addresses my company is on 10.x.x.x network.iam also amazed why this error is coming.how can 3 ip address some body using at same time.i dont thnk finding host can be possible bcz no one is on othernetwork.ihave other server as secondary that server is on 192.x.x.x. network no one is using this ips.so plz telme how to resolve the issue.

yes - but remember you still have to fix arping

My understanding of the issue is that arping is broken (from wrong arch package / whatever) - as it gives "bad ELF interpreter" message. So in ifup-eth script it returns error, and this script interprets it as duplicate IP. Of course it may be the interpreter problem - but probably not if it's still possible to issue other commands. And if that's a file for another arch for example, then all the files from its package will have this problem, and there may be more wrong packages installed..

tnx very much for ur support i appreciate it.
but telme now i need to type those 2 commands from #root or in ifup-eth.plz be specfic.i dont know why this error is coming.ijust want to resolve the issue.after typing those 2 command wht next??plz telme the steps iam waiting for ur reply.

i have type the 2 commands on root.but still the same error is coming.now wht should i do plztelme

so just typing:
% true
in shell also gives: "bad ELF interpreter"?

paste the output you get from "service network restart" here

bro same error as i got from previous occsaions.plz check the starting posts.nothing changed after typing those 2 cmds.i have type those 2 cmds without% on root bcz it will not accept %cmd on root.that same bad elf interpreter error is coming.how to solve this issue.this error driving me nuts.

It may be the path sequence, on my system /usr/sbin/arping is just a link to /sbin/arping, so you'd have to replace /sbin/arping in that case:
as 'root' or with 'sudo'

or check your paths - may be different:
and the PATH in /etc/sysconfig/network-scripts/network-functions

sure, % is just my prompt - don't use it

/sbin/arping is the right path - it's in the initial post, so:
as 'root' or with 'sudo'

hi yesturday it was off so i didnt post any thng here.i have found out that glib package is missing that y its giving the error called bad elf interpreter.whn i want to install that package my internet is off on that system.im not able to access my cdrom nor pendrives its giving ur not authorized to do that.so now plz telme how can i install that package.i have got struct here...plz helpme

How do you access them?
Are you mounting the drives as root?


Kind regards

ya im mounting the drives.but due to bad elf interpreter error im not able to access the cddrom nor pendrives nor external drives anythng.i suspect someone might have hacked my server.......no commands are working as of now. i suspect some packages might have lost......
few days ago when the screensaver page was coming if i touch the keyboard or mouse my login page was coming but from the last 2 3 days ago my loginpage wasnt coming..then slowly my server was getting hang now it totally got out of service.so plz any expert helpme on this.....wht should i do know . i cant reboot my system without informing my manager.but i dont want to do that as of now......

I don't think a hacker would shut down the connection.
Do you have a backup of the server?
Seems to me you erased, replaced or upgraded glibc.
However, if you really think your system is compromised, start here:

Since your server is down for a few days, don't you think the manager will know?
Wouldn't it be better to talk to your manager about the problem?


Kind regards
