Martin, sorry but this is a bug and needs to be addressed. My fix for ipv6 doesn't solve this specific issue.
There are multiple problems here. one n-m that doesn't know how to cope with alias interfaces. two the kernel brings down the alias interfaces when shutting down the main one (that's what triggers n-m to remove everything basically). The kernel "issue" is a well known and wanted behaviour. NM needs to grow a patch similar to the ipv6 one in order to track nextsamealias and ignore the main interface if the pointer is non null in the list. Fabio PS alias interfaces are common and support. we support the kernel and we do support ifupdown and they work just fine here. ** Changed in: network-manager (Ubuntu) Status: Fix Released => Confirmed -- ifup fails to bring up alias interfaces like eth0:10 https://bugs.launchpad.net/bugs/95968 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [EMAIL PROTECTED] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
