I don't think I do have Piranha-related questions; at least, the ipvsadm output looks perfectly reasonable to me. I think I've got a correct configuration on the LVS node.

But I had another route back into the main corporate LAN due to a secondary interface being turned on, and that turns out to have been causing the trouble. Once I got that turned off, I get traffic distributed across both realservers. I examined this more carefully when you pointed that out as a key requirement, so thank you! -- David Dyer-Bennet, [EMAIL PROTECTED]; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info _______________________________________________ LinuxVirtualServer.org mailing list - [email protected] Send requests to [EMAIL PROTECTED] or go to http://lists.graemef.net/mailman/listinfo/lvs-users
