    linux clock slow

    on both my home machine and my dedicated server (RH 8.0), the clock slows gradually over time (a minute or two per week?). this ranges from annoying to bad, depending on the application, and i'm trying to figure out how to fix the problem.

    a google search seems to point to ntpd - are there any security issues to watch out for when using this utility? i'd rather keep as few programs running on my box as possible...

    Daniel,

    I never heared any security issues with ntpd.

    Have a look on http://www.webhostingtalk.com/showth...hreadid=257641

    Hope this helps.

    imo its enough to run ntpdate once a day, its unlikely you need your system time sync'ed with 1ms precision

    The security issue isn't with ntpd but with your OS. Psyche (redhat 8) is 3-4 years old, and has been discontinued. Even updates for this from legacy are through with, so you're excluding yourself from serious, critical updates.

    you could also add the following line to /etc/rc.local and it'd sync up at boot

    rdate -s rdate.darkorb.net&

    For the most part, that's all you need to keep your clock up to date.

    Just add a nightly crontab entry to run ntpdate, and have it check against your favorite time server.

    sync everything on your network including your routers with the same ntp server assuming you are in control with all of these. Having all your equipment sync'd is paramount for your logs
