I solved this problem! The reason is that networking subsystem does not start at boot. I don't know why Canonical decided to do that)) You can add /etc/init.d/networking manually or by this command
# update-rc.d networking defaults (i do this by sysv-rc-conf program (you can check by this program if networking script is started), but it must be installed manually by apt- get install) ** Changed in: ifupdown (Ubuntu) Status: New => Fix Released -- 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
