However, I would like tap0 being first and of course > without any output ordering trick. The order is dictated by the order the drivers are probed by the kernel. When the devices are created they are added to a linked list. There is no practical way to control the order and it has little or no effect. -- Brooks --ZJcv+A0YCCLh2VIg Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (FreeBSD) iD8DBQFRbXHWXY6L6fI4GtQRAnu9AKCAx1z0Ns3LdGZb+OEthXHUXoubAQCgr0YG ba2xOdoX8hi1TH33bqevAFE= =vPsr -----END PGP SIGNATURE----- --ZJcv+A0YCCLh2VIg--
