Hosts ping didn't work anymore

[Matthieu Jacquart]

Hi,

It’s not a big deal but since few months, hosts ping didn’t work : all pc already in fog console are always marked as red even if they are online with display “operation not permitted”.
And strange thing is : newly added hosts are always marked as green with “success” display even if they are shutdown…

Thanks
Matthieu

[Tom Elliott]

The detention is not perfect. Operation not permitted is the actual message returned when trying to perform the action. New hosts will always show as success because it hasn’t pinged yet.

[Matthieu Jacquart]

Ok, it’s not a problem, it’s just surprising that all former pc are always in red (computers already in database before arpil/may) and all new one (since may) are always in green even if they have already been start/stop several times.

[Tom Elliott]

@Matthieu-Jacquart just a guess but anything in Apache logs or the phone bg hosts log?

[Matthieu Jacquart]

@Tom-Elliott you need for apache : /var:log/apache2 error or acces.log ?
And where is store phone bg hosts log ?
Thx

[Tom Elliott]

error logs, and It’s found in the same place all other fog service logs are, typically (/opt/fog/log)

[Matthieu Jacquart]

@Tom-Elliott So for Apache2 error.log

But in opt/fog/log I have no phone bg hosts log

[Tom Elliott]

@Matthieu-Jacquart Sorry my phone sucks.

Pinghosts is what I was looking for.

[Matthieu Jacquart]

@Tom-Elliott I supposed it was this one
Nothing new in this file since October 2015 ! As for most of fog log file if you look at my previous post, strange no ?

[Tom Elliott]

Real strange yes.

[Matthieu Jacquart]

@Tom-Elliott I moved these log files and reboot server but /opt/fog/log is empty, log files don’t regenerate…
Anything to do to force this ?

[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 :

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