• hi,

    I have searched the forum and found a few topics, but none of them solved the problem.

    The logs show that everything is ok, but anyway, it still shows that the host is unknown.

    Your version of FOG is up to date.
    You're running the latest stable version: 1.5.9
    Versões do kernel
    bzImage Version: 5.10.71
    bzImage32 Version: 5.10.71

    Any ideas?

    @eliaspereira So does it work now that you fixed name resolution on the FOG server?

    At first, yes.

    Thanks again for the great help!!!

  • @george1421 said in Host status is unknow 2:

    @eliaspereira OK, lets find out a bit more about your network setup.

    1. What device is your dhcp server?

    We use pfsense as firewall and dhcp server.

    1. Can you resolve the computers by DNS?

    Now, yes. I configured the samba4 AD DNS on resolv.conf from fogserver.

    1. Are the host names registered in FOG match the physical host name on the target computer?

    Yes.

  • @george1421 said in Host status is unknow 2:

    @eliaspereira No fog is configured to only use the hostname because often the IP address is assigned by dhcp.

    Ok.

    How many computers are you trying to manage here?

    Over 365 computers.

    @eliaspereira Ok this issue is totally a name resolution issue based on the testing you have done so far.

    FOG uses port 445 to query the target system.

    So to start debugging this see if you can ping lab04pc02 If unable to resolve the name lab04pc02 (as named in the fog host definition) then that is your problem. Depending on the linux distro you use you need to use the network manager application to point the FOG Server’s DNS server value towards you internal DNS resolver. So that the FOG server can map lab04pc02 to an IP address.

    Hello @george1421 , Thank you for your help!

    Can I set fog to ping the IP address instead of the domain name?
