Ladies and gentlemen, Playing with Wireshark and seeing "Gratuitous ARP for 63.209.4.211 (Request)" coming from my Fedora 12 ftp server. The ip address is a bit of a mystery since this is a fresh install, and I couldn't find any nic card setup in the bios which could contain this number. Must be in the server somewhere. Who's gonna solve this one? Where can I look?
There are a couple possibilities. If a machine has two NICs on thesame IP you'll get that message. The offender could be another physical NIC or an alias of another NIC (e.g. "eth0:0").
Another possibility is that you have a bond running (two NICs set up as either a failover pair or an aggregate). If the system fails over from one NIC to the other one (or if it switches when load sharing), an ARP may be sent--depending on the bond type. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, C2 Hosting ricks@xxxxxxxx - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - "Microsoft is a cross between The Borg and the Ferengi. - - Unfortunately they use Borg to do their marketing and Ferengi to - - do their programming." -- Simon Slavin - ---------------------------------------------------------------------- _______________________________________________ Redhat-install-list mailing list Redhat-install-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/redhat-install-list To Unsubscribe Go To ABOVE URL or send a message to: redhat-install-list-request@xxxxxxxxxx Subject: unsubscribe
