    Fedora losing its IP address randomly...


    Hi guys,

    A fedora machine is losing its IP address randomly, there is no trend that I can see when it loses its IP address. It is Fedora release 13.

    All I can get from /var/log/messages when it loses its IP address is following log lines:

    Can anyone please throw some light on this?

    Hello.
    If you have the time, you could investigate your dhcp and network settings. Avahi is for netzero ip addressing, so I'm not entirely confident why it should be handling anything if your not plugnplay network hopping.

    I prefere to point my lan network at one dhcp server, turn off netzero (i.e.- avahi services). At the dhcp server I can control address lease times, address ranges (etc).

    I'm guessing you're not using a dhcp based connection (or perhaps 2 dynamic ip client setups) and you have a very inquisitive ntp service or something else!
