    warning: time of day goes back, taking countermeasures


    i just installed redhat 7.2 on a compaq ap400 wrk.station. i have installed several 7.2 boxes but on this one for some reason i keep getting the following error when trying to ping:

    Warning: time of day goes back, taking countermeasures.

    sometimes i get host unreanchable when trying to ping a host that i could ping 5 mins ago. if i reboot the computer i can ping the host again but the above error is still there? the time reported on the computer is correct. any ideas?

    The reason it says time of day goest back, is your system clock is not synced to the rest of the network. Try the command ntpdate. I had to download the new version for it to recognize any time servers. (try doing a search on google for ntpdate servers). Also if you cant ping your other machines, take a look at your routing tables. Mine likes to reset spontaneously.
    If it has reset then: route add default gw your.ip.address.here

    p.s. sorry if you already knew all that
