Hi Now that udev has reached Debian sarge, I've installed it, with no major hassles. However, my tun/tap network devices no longer come up: tap0: ERROR while getting interface flags: No such device and /dev/net/tun does not exist. Is anybody successfully using a 2.6 kernel and tap devices? Any pointers? Google and the udev docs have given me surprising little hope with this issue. Regards Damien |

My advice is to create the node with "mknod tun c 10 200" and chmod as you see fit. The best place to ask is the linux-hotplug list ;) Regrds, Nuno Silva -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFAaF/+OPig54MP17wRAjVxAKDb5+/ZTwh9VPd2NhR3b/49PiyhpwCgnxTt hODmDWK2JxISVBIf1s5RU3s= =cC5t -----END PGP SIGNATURE----- |

It isn't udev's fault; it is a hotplug problem with the tun driver. I've attached a patch that fixes this. This patch (or something like it) should be in the 2.6.5 release. regards, Mike -- Mike Snitzer msn...@ln... Linux Networx http://www.lnxi.com |
