State Changed From-To: open->feedback I can't reproduce that here with 4.5-RC. Is this still a problem for you with the latest -STABLE? State Changed From-To: feedback->closed ashp changed this to feedback almost a year ago. He cannot reproduce this and I can't either. Closed. |
The first physical interface (fxp0 in my case on a box with fxp0 and fxp1) always gets an IPv6 link local address, even if IPv6 is disabled in /etc/rc.conf. Note, this causes big issues when trying to configure the first interface (fxp0) as IPv4 only and the second interface (fxp1) as IPv6 only. Fix: Unknown. Suspect something in the kernel initialization, as making /etc/rc.network6 an empty file does not change the behavior. How-To-Repeat: Try this config in /etc/rc.conf: network_interfaces="fxp0 lo0" ifconfig_fxp0="inet 209.249.106.101 netmask 255.255.255.240" defaultrouter="209.249.106.97" ipv6_enable="NO" hostname="ussenterprise.ufp.org" After booting, ifconfig fxp0 will show an IPv6 link local address, like this: fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet 209.249.106.101 netmask 0xfffffff0 broadcast 209.249.106.111 inet6 fe80::2e0:18ff:fe02:6f07%fxp0 prefixlen 64 scopeid 0x1 ether 00:e0:18:02:6f:07 media: autoselect (10baseT/UTP) status: active supported media: autoselect 100baseTX <full-duplex> 100baseTX 10baseT/UTP <full-duplex> 10baseT/UTP
