mizar:[/etc/network/if-up.d] cat ntp #!/bin/sh # remove (or comment out) the next line if your network addresses change exit 0 case $ADDRFAM in inet*) if [ -x "/etc/init.d/ntp" ]; then if [ -x "`which invoke-rc.d 2>/dev/null`" ]; then invoke-rc.d ntp restart || exit $? else /etc/init.d/ntp restart || exit $? fi fi ;; esac -- ntp starts before the network is up in feisty https://launchpad.net/bugs/90267 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
