bonding error

[Alphonse Bosch <alphonse bosch p-o be>]

hello

we've have installed fedora-core-2 on a server with kernel
2.6.10-1.12-FC2 and when we configured the bonding system with two
network interfaces it works but when we ping other servers in the
network we have on each ping DUP! errors
I saw on a link that you have to install the last ppp packet from
fedora-core-2 updates site but it isn't stil working
i have still the same problem

Is there anybody who can help me
