    64 bytes from pz-in-f100.google.com (74.125.127.100): icmp_seq=3 ttl=45 time=193 ms
    but, i CANNOT ping any in my.local domain
    Code:
    deneb:~ # ping dipsy
    ping: unknown host dipsy
    or
    Code:
    deneb:~ # ping dipsy.my.local
    ping: unknown host dipsy.my.local
    I can ping dipsy with ip addres
    deneb-F50:~ # ping 192.168.80.17
    PING 192.168.80.17 (192.168.80.17) 56(84) bytes of data.
    64 bytes from 192.168.80.17: icmp_seq=1 ttl=64 time=0.587 ms
    64 bytes from 192.168.80.17: icmp_seq=2 ttl=64 time=0.094 ms
    64 bytes from 192.168.80.17: icmp_seq=3 ttl=64 time=0.093 ms

    You can ping in your local domain, which you prove by your ping to the IP address. But hen you ping to the hostname, ping tells you that this name can not be resolved (tranlated to an IP address). Not only ping, but every trial to connect to dipsy (or dipsy.my.local) with e.g. telnet, ssh, browser will have the same result.

    For the resolve to succeed dipsy must be either in your /etc/hosts, or in the DNS server at 192.168.80.1 (something you are aware of). dipsy is not in your /etc/hosts. You could btw test by adding
    Code:
    192.168.80.nn   dipsy.my.local     dipsy
    to your /etc/hosts.

    So it must be in your DNS server, but you did not show us it is. You tell that other openSUSE levels do function, but you do not show their /etc/hosts, dipsy could be in there.

    You can use the nslookup and/or host utilities to interogate your DNS server.

    Try adding the following parameter to /etc/host.conf
    Code:
    mdns off
    I'm not sure if this applied to 9.4, but currently the default is off
    and ".local" addresses are treated as special and are resolved(or not) by
    multicast. See:
    Code:
    man host.conf

    The above should have read "on". PV
