Issue with Ping command on newly setup Network - "Bad value for option -c"

[sean.sun]

Hi Champs, so after I create network, and have other member joining the network, when I try to Ping other IP address, the following error “Bad value for option -c” pop up. I have checked the firewall even exit the anti-virus software but same error still occurs. Any one have experience on resolve this error? Thanks.

Unrelated to ZeroTier. Run the command without arguments and read the output.

Hi Andrew - Thanks, sorry what is arguments?

I have no idea with a “routing compartment identifier” is, but that’s what the “-c” argument is for according to the command help. Remove the “-c 5” from the command and try again
