Public bug reported: Binary package hint: ifupdown
This is very similar to Bug #123773, but is specific to IPv6 and should probably be tracked separately. I don't have an instance ready to retest on, but this apparently worked on Jaunty (9.04) and broke on Karmic (9.10). I'm actually re-using the "/etc/network/interfaces" file that I used successfully under Jaunty before upgrading to Karmic. Per the IFCONFIG(8) man page, I'm attempting to define an IP alias in /etc/network/interfaces: auto eth0 iface eth0 inet static address 192.168.1.1 netmask 255.255.255.0 auto eth0:0 iface eth0:0 inet6 static address 2001:db8::1 netmask 64 (2001:db8::1 is only an example address.) Attempting to perform an "ifup eth0:0" results in: SIOCSIFFLAGS: Cannot assign requested address Failed to bring up eth0:0. Unlike Bug #123773, this is not coming from the wireless-tools or other event scripts, as disabling them does not change the result. The following command is a work-around, and works as a post-up command in /etc/network/interfaces: ip addr add 2001:db8::1/64 dev eth0 Defining an IPv4 alias also works correctly using either the alias stanza or the "ip addr add" command. uname: Linux 2.6.31-17-generic #54-Ubuntu SMP Thu Dec 10 17:01:44 UTC 2009 x86_64 GNU/Linux ifupdown package version is 0.6.8ubuntu21 ** Affects: ifupdown (Ubuntu) Importance: Undecided Status: New ** Tags: ipv6 network -- 'SIOCSIFFLAGS: Cannot assign requested address' when setting up IPv6 alias https://bugs.launchpad.net/bugs/508996 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
