[Solved]Machines appear with red dot in hosts management

[processor]

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

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.

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

[processor]

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

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.
