      Hi,

      I’m using a fog upgraded from 1.5.5 to 1.5.6 on a Ubuntu 16.04.

      All my machines in hosts management appear with a red dot.
      Before today the DNS which FOG refers did not had any register for my machines.
      Today I corrected this. Now I can see all hosts on my DNS, and a ping from the FOG server show me that the machines names are well resolved.

      I made a snapin that open ICMPv4 and UDP port 7 inbound on each machines.

      the command :

      systemctl -l status FOGPingHosts
      

      output this :

      ● FOGPingHosts.service - FOGPingHosts
         Loaded: loaded (/lib/systemd/system/FOGPingHosts.service; enabled; vendor preset: enabled)

                 └─2066 /usr/bin/php -q /opt/fog/service/FOGPingHosts/FOGPingHosts &
      
      mai 28 16:31:04 FR2-FOG-01 systemd[1]: Started FOGPingHosts.
      

      What could be wrong and what should I do? At which frequency the fog server check the existence of the hosts?

      Many thanks by advance.

      Proc.

        @processor Not sure if I asked in another topic but how many hosts do you have?

        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)

          Hi Sebastian,

          I have about 300 hosts.

            @processor Should take about 10 minutes for your 300 hosts to ping. I can imagine that a firewall is blocking the ping (not ICMP but TCP port 445!). See some more information on this here: https://forums.fogproject.org/topic/12669/fog-doesn-t-detect-the-status-of-the-clients

            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)

              Hi,

              Thanks works better with TCP port 445. I was referring this wiki :

              https://wiki.fogproject.org/wiki/index.php/Troubleshooting_Host_Management_Showing_Hosts_as_Down

              It’s solved.
