The command is currently: /bin/ping -c1 -w500 gateway I hope this command will fix it: /bin/ping -c1 -w500 -W500 gateway (In reply to Florian Best from comment #1) > The command is currently: > /bin/ping -c1 -w500 gateway > I hope this command will fix it: > /bin/ping -c1 -w500 -W500 gateway Omg. -w takes seconds not milliseconds. Changing it to /bin/ping -c3 -w4 -W4 gateway patch applied. YAML added. OK - debian changelog OK - yaml OK - gateway ping does not block diagnostic-module anymore |
Created attachment 6472 [details] umc-system-diagonostic.png If the gateway doesn't answer on ping request, the UMC system diagnostic module hangs for a long time, several minutes. See attached screenshot. It is not really clear if the module is still doing something. You can simply reproduce it by dropping all outgoing ping requests: iptables -A OUTPUT -p icmp --icmp-type echo-request -j DROP I think it is a common situation that a gateway doesn't answer ping requests. At least we got this feedback.
