why are you trying to put both interfaces on the same subnet? That's not how networking works...
|
Thanks for quick reply
i have 2 interface on server i have given static ip to both interface as i run one localapplication from one interface and other local application from other interface hence have ip on same network |
Right. Well... don't. use one nic. Or bond them. If you need to IP's you can alias them to have an eth0:1 interface on the same nic.

Hi
Thanks for suggestion ,but To avoid network traffic on one interface i have use 2 interface from last 2 years there is no issue from my above logs i.e someone advertises our address on eth1! it means that someone use this same ip on some where |
why would you want to avoid traffic on one interface??
I can see the duplicate ip message, but it seemed more prudent to raise the fact that you're fundamentally using the network incorrectly. |
Hi
as i have more than one application in my server and if all user accessing same application at same time then the application is slow for this i use 2 interface , the error log as posted above is due to this like error "someone advertises our address on eth0" |
well you should be doing NIC bonding then. Anyway... so you clearly have a duplicate IP, so go fix... not sure what else we can say about that.
|
Thanks for reply
once thing i forgot to share that yesterday i use at command to shutdown the server in morning as at 7am wednesday at>halt ctrl+d is this cause this problem AMAR |
no, it's not.
|
i aggree i have to use 2 interface as you explain me , but what cause this error as i explained in my log so that i can troubleshoot main cause
|
well it says something else has the IP, so find what device that is.
