When i use ntpdate to correct it i get an Error. Also connect to an ip for ntpdate dont work.
Does anybody has an hint for me?

What can i do that i can connect to the ntpservers. The firewall is not blocking.
I think there is no entry for the Gateway in the network settings. But where i found the network settings?

For some reason, ACC does not come with an "/etc/services" file usually found on Linux systems. I'll check that.

The upshot is that you need "/etc/services" for ntpdate to work; the rather confusing error message complains that ntpdate does not know what ports the service name "ntp" is associated with. Either copy an "/etc/services" from a different Linux machine, or create such a text file containing at least the following two lines:

ntp 123/tcp
ntp 123/udp

If you can ping the NTP server, things should work as expected then.

Yes, there needs to be a way to have ACC automatically sync up. I found my ACC 1.301 to be about 12 hours off of current time.

Here's how to create a cron job to manually sync up with a NTP server of your choice:

1. Log into ACC via console as root.
2. Type `crontab -e`
3. Insert a line that looks like this to sync up the time once an hour:
0 * * * * /usr/sbin/ntpdate ntpserver > /dev/null

Replace ntpserver with your local ntp server.
Quit the editor and it will save your changes.

You can check /var/log/system.log after the next hour rolls over and you should see that it runs.

Hi,

thanks for your patience on this issue. It is quite evident that ACC misses features to adjust date and time related settings - manually or automatically. We will take this into account for future releases but definitely not for the upcoming one.

Cheers

For now, the manual crontab entry seems to be doing a decent job.
