Hi, One note on CARP and VRRP moving forwards. I realize that this patch is = partly a CARP specific issue but a lot of people on a few mailing lists seem to = have assumed that VRRP is no longer under patent threat. According to the FreeBSD Foundation's lawyers there are two extant patent= s, due to expire in 2017, 3 years hence. = CISCO =E2=80=93 US6108300: Method and apparatus for transparently providi= ng a failover network device = IBM: US6148410: Fault tolerant recoverable TCP/IP connection router, Bas= key, Dillenberger, Goldszmidt, Hunt, Levy-Abegnoli, Nick,Schmidt, Novembe= r 14, 2000. = So let's not go assuming that VRRP is "free" just yet. As to updating our CARP to behave correctly, that's still on the table. Best, George --=_MailMate_8591B0AD-C432-4569-8F7A-3A0730619473_= Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.22 (Darwin) Comment: GPGTools - http://gpgtools.org iEYEARECAAYFAlODdNcACgkQYdh2wUQKM9IPlACcDenpylH6IMpVHxS0wgqJKEPQ 8/sAn3DfeoJK0XiTQE5NCNI//BxGfdk8 =5zx6 -----END PGP SIGNATURE----- --=_MailMate_8591B0AD-C432-4569-8F7A-3A0730619473_=--
