      @ch3i Or make sure the DNS Resolver is a part of the named/search of the /etc/resolv.conf file.

      Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG! Get in contact with me (chat bubble in the top right corner) if you want to join in.

      Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

      Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG

            Hello, and where can I do this?

            Ok, in my debian server I have do that :

            apt-get install resolvconf
            vi /etc/network/interfaces
            

            Add those lines to my interfaces file :

            dns-nameserver xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy
            dns-search domain1.com
            dns-search domain2.com
            

            Save file and run (it’s to update /etc/resolv.conf file):

            resolvconf -u
            

            Content of resolv.conf file :

            # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
            #     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
            nameserver xxx.xxx.xxx.xxx
            nameserver yyy.yyy.yyy.yyy
            search domain1.com
            domain2.com
            

            Now ping in FOG is functional.

                  Can you try to ping a host with shortname and FQDN like that :

                  ping 74_armazem
                  
                  ping 74_armazem.yourdomain.com

                    I have a machine with attached HP35076 hostname is a machine with WIN 7 I can ping the IP of this machine. but I can not ping the hostname.

                    Maybe the problem is in my pfsense or own firewall Win 7.

                    if I can ping out of my fog to www.google.com for example the problem may be in the firewall of my machines windows 7 or even pfsense that makes the management of all of my networks.

                      It’s not a FW problem if you can ping the IP.
                      It’s a DNS problem, have you a domain ? have you a DNS server configured in your machines ? If yes provide me those informations.

                          Are your machines part of a domain? Try adding the domain to the end.

                          My domain is test.local in order to ping Laptop-2 I have to run:

                          
                          root@Fog:~# ping Laptop-2.test.local
                          PING Laptop-2.test.local (10.1.111.254) 56(84) bytes of data.
                          64 bytes from 10.1.111.254: icmp_req=1 ttl=127 time=138 ms
                          64 bytes from 10.1.111.254: icmp_req=2 ttl=127 time=180 ms
                          64 bytes from 10.1.111.254: icmp_req=3 ttl=127 time=1.54 ms
