DSM-G600, DNS-3xx and NSA-220 Hack Forum

Just some information that may be useful for some people... following on from the topic below:
http://dns323.kood.org/forum/t149-jobs.html

The DNS-323 clock drifts by about 4 minutes per day. Out-of-the-box, the NAS runs a 'rtc' Cron task every night to correct the clock by 227 seconds. Of course, this means that by the end of the day, timestamps etc would be out by almost 4 minutes. This 4 minutes is corrected at one time, which could be "interesting" if there was a lot of file activity just then, or if logging is important.

My DNS-323 runs Etch, and I was able to install ntpd (Run "apt-get install ntp", and start the daemon from Etch on startup). This corrects the system clock every twenty minutes, by which time the drift has reached a little over 3 seconds. A much better solution, IMO.

I added the following to fun_plug to remove the root cron jobs, and reinsert the 'getdhcp' task that may actually be useful.

# replace Cron daylight jobs
crontab -r
echo '*/10 * * * * /usr/sbin/getdhcp&' > /var/spool/cron/crontabs/root
crontab /var/spool/cron/crontabs/root

In performing the above, I also purposely omitted the 'daylight' cron task - we know that task causes difficulty with the DNS-323 in all firmware versions up to the current one (1.03), so it is of limited benefit. My understanding is that by running 'tzconfig' and setting the correct timezone, Debian will take care of deylight savig time for me.


Cheers,
