Six day before that, you could make your WOL wake you 10 minutes earlier. Later won't work, you'll be late When DST ends in central Europe, clocks retreat from 03:00 CEST to 02:00 CET on last Sunday in October. #min hour day month dayofweek command 59 05 * * 1 /usr/bin/wol -h 192.168.1.255 xx:xx:xx:xx:xx:xx # Mo #crontab muss (wie fstab) in leerzeile oder kommentar enden crontab manpage http://adminschoice.com/crontab-quick-reference see http://www.busybox.net/downloads/BusyBox.html for options /etc/iproute2/rt_tables This is the configuration file for the routing.

Both files are not executed when booting into failsafe mode. You can populate this file with help of netfilter-article. /etc/fstab Merely a symlink to fstab → /tmp/fstab which is being created and configured by UCI in /etc/config/fstab manpage fstab, fstab /etc/functions.sh /etc/functions.sh does stuff /etc/fw_env.config → uboot.config /etc/group /etc/group is an ASCII file which defines the groups to which users belong to. See man group /etc/hosts On top of IP addresses we use hostnames to refer to devices in the network. As there are FQDN, so are internal hostnames. Edit the file /etc/hosts: 192.168.1.1 openwrt openwrt. 192.168.1.1 name1 name1. 192.168.1.1 name2 name2. 192.168.1.2 user1 user1. 192.168.1.254 dockstar dockstar. After rebooting you can address your network devices not only by their IPs, but by their domain names, e.g. openwrt.lan or dockstar.lan etc. The uci method for setting the hostname of the OpenWrt system itself is via /etc/config/system: config system option hostname lila /etc/hosts.allow man hosts.allow or hosts.allow /etc/hosts.deny man hosts.deny or hosts.deny /etc/hotplug2-common.rules /etc/hotplug2-init.rules /etc/hotplug2.rules /etc/init.d/rcS This get's executed by init every boot: init #!/bin/sh # Copyright (C) 2006 OpenWrt.org run_scripts() { for i in /etc/rc.d/$1*; do [ -x $i ] && $i $2 2>&1 done | $LOGGER } system_config() { config_get_bool foreground $1 foreground 0 } LOGGER="cat" [ -x /usr/bin/logger ] && LOGGER="logger -s -p 6 -t sysinit" . /etc/functions.sh config_load system config_foreach system_config system if [ "$1" = "S" -a "$foreground" != "1" ]; then run_scripts "$1" "$2" & else run_scripts "$1" "$2" fi /etc/inittab http://linux.die.net/man/5/inittab ::sysinit:/etc/init.d/rcS S boot ::shutdown:/etc/init.d/rcS K shutdown tts/0::askfirst:/bin/ash --login ttyS0::askfirst:/bin/ash --login tty1::askfirst:/bin/ash --login /etc/mtab mtab, → filesystems, →flash.layout, procfs, sysfs, devpts rootfs / rootfs rw 0 0 /dev/root /rom squashfs ro,relatime 0 0 proc /proc proc rw,noatime 0 0 sysfs /sys sysfs rw,noatime 0 0 tmpfs /tmp tmpfs rw,nosuid,nodev,noatime 0 0 tmpfs /dev tmpfs rw,noatime,size=512k,mode=755 0 0 devpts /dev/pts devpts rw,noatime,mode=600 0 0 /dev/mtdblock3 /overlay jffs2 rw,noatime 0 0 overlayfs:/overlay / overlayfs rw,noatime 0 0 debugfs /sys/kernel/debug debugfs rw,relatime 0 0 none /proc/bus/usb usbfs rw,relatime 0 0 /etc/ntp.conf /etc/opkg.conf →opkg /etc/passwd → manpage passwd /etc/preinit In OpenWrt the Kernel is executed by the bootloader with the option init=/etc/preinit (instead of the usual init=/sbin/init).
