Hosts ping didn't work anymore

[Wayne Workman]

@Matthieu-Jacquart try to just touch the file to make a blank file, give it 777 permissions and see what happens.
touch /opt/fog/log/pinghosts.log
chmod 777 /opt/fog/log/pinghosts.log

I briefly looked over this thread - no mention of firewall so far… check that? What about SELinux?

[Matthieu Jacquart]

@Wayne-Workman Ok done and update to last git, any changes…
And no rules in debian FW (/sbin/iptables -L)

[Tom Elliott]

@Matthieu-Jacquart Is your server GUI based (do you open using xterm/terminal?) I ask because I’ve seen where logs don’t get written and most commonly it’s how the system was installed. Many people run: ./installfog.sh -y which is fine in most cases, but if you’re already root (xterm – then sudo su rather than sudo -i or sudo su - or signed directly in to GUI as root), the root paths aren’t properly solved out. This is fixed, often, by changing how you’re becoming root.

[Matthieu Jacquart]

@Tom-Elliott So, I’ll try to well respond, but not sure to have understood everything
My installation is a debian 8 without graphic interface, and I connect with SSH directly with root account.
I just run ./install.sh (without -y)

[Wayne Workman]

This is just a thought but if host ping is having issues - wouldn’t there be logs about that in the apache error logs?

On Debian that might be /var/log/apache2/error_log

[Matthieu Jacquart]

@Wayne-Workman there’s just this in error.log :

root@FOG:~/fogproject/bin$ cat /var/log/apache2/error.log

Not going to help much, I’m sure, but what about output of:

systemctl status -l FOGPingHosts

[Matthieu Jacquart]

@Tom-Elliott

[Tom Elliott]

@Matthieu-Jacquart Is apparmour, by chance, blocking stuff?

[Matthieu Jacquart]

@Tom-Elliott What ? Sorry, don’t understand

[Tom Elliott]

@Matthieu-Jacquart When you get a chance can you run:

sudo chmod +x /lib/systemd/system/FOG*

Then try restarting FOGPingHosts with:
systemctl restart FOGPingHosts

Followed by:
systemctl status -l FOGPingHosts

[Matthieu Jacquart]

@Tom-Elliott

Don’t know if it will help but here are some things on the net that reference the same error.

[Matthieu Jacquart]

@Wayne-Workman Thanks but I’m not expert in linux and I don’t find solution in these articles…
I don’t know how to resolve my problem, but once again it’s not a big deal…

[Tom Elliott]

@Matthieu-Jacquart Can you try:

chmod +x -R /opt/fog/service/

[Matthieu Jacquart]

@Tom-Elliott YES !
Update to last version, apply your command, reboot fog server, and now there are all service log updated.

And in fog management, ping is 100% ok, only online computers are green.

Case is solved for me

[Wayne Workman]

Weird… wonder how it got that way?
