    howto start ntpdate after restart ?

    hi

    on my debian sarge stable I have in cron.hourly the following entry:
    Code:
    debian:~# cat /etc/cron.hourly/ntpdate
    #!/bin/sh
    
    /usr/sbin/ntpdate -v 130.133.1.10 131.188.3.220 193.67.79.202 ; /sbin/hwclock --systohc > /dev/null 2>&1
    because I'll synchronize the system time every hour,

    but the machine has a wirelless card with wpa encryption and the cron will start before the internet connection, so the system is hanging each time during the restart.

    could someone help me pls to solve this problem ?
    maybe to put "if any" to this script ?

    kind regards
    ccc

    It should be easy to accomplish that.. what you need to check is that "if" there's a file.. or a process running, or whatever, run the rest of the commands or not. Check the following links:

    Hope it helps bro.

    This is my /etc/cron.daily/timesync bash script:

    #!/bin/sh
    /usr/sbin/ntpdate time.cableol.net && /sbin/hwclock -systohc


    ** time.cableol.net/valiant.cableol.net is NTLs NTP server here in the UK.
    This works perfect for me on a 24 hourly update. Note the missing '> /dev/null 2>&1'
