I also have this problem with jaunty/server. My workaround is to comment out the auto line for the alias and us post-up / pre-down to bring the aliases up:
auto eth0 iface eth0 inet static address 1.2.3.4 broadcast 1.2.3.255 netmask 255.255.255.0 gateway 1.2.3.1 post-up ifup eth0:0 pre-down ifdown eth0:0 # no auto here! iface eth0:0 inet static address 2.3.4.5 broadcast 2.3.4.255 netmask 255.255.255.0 -- ifup -a does not start alias interfaces https://bugs.launchpad.net/bugs/114457 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
