I'm not sure I saw anyone mention this, so I'll add it. This symptom can be caused by a device in the network performing proxy arp. Reasonable culprits are things that do "fancy" NAT. Unreasonable culprits are hosts made to do the bidding of evil-doers by crashing VLANs and performing MitM tricks.
An example of the former is a Cisco PIX with statics on a lower security interface. To stop the behavior in this case you'd use the not-so-well documented command "sysopt noproxyarp <interface>". Anyway, this is just an example to help you consider possible culprits in your environment. -----Original Message----- From: Chris Knowles [mailto:[EMAIL PROTECTED] Sent: Sunday, February 13, 2005 1:07 AM To: Triangle Linux Users Group discussion list Subject: [TriLUG] Odd Network problem -- TriLUG mailing list : http://www.trilug.org/mailman/listinfo/trilug TriLUG Organizational FAQ : http://trilug.org/faq/ TriLUG Member Services FAQ : http://members.trilug.org/services_faq/ TriLUG PGP Keyring : http://trilug.org/~chrish/trilug.asc -- TriLUG mailing list : http://www.trilug.org/mailman/listinfo/trilug TriLUG Organizational FAQ : http://trilug.org/faq/ TriLUG Member Services FAQ : http://members.trilug.org/services_faq/ TriLUG PGP Keyring : http://trilug.org/~chrish/trilug.asc
