The Diagnostics screen is a convenient way to run low-level commands for troubleshooting.
Ping
-
The IPv4 Ping field can be used to 'ping' a target IP or FQDN.
-
'ping' uses the ICMP protocol's mandatory ECHO_REQUEST datagram to elicit an ICMP ECHO_RESPONSE from a host or gateway.
-
When used with the '-i', '-v', or '-l' options, specifies the interface or VLAN through which the ping is conducted.
-
The 'ping-options' are the same as in the usual Linux 'ping' command.
-
Run 'man ping' for details of the Linux 'ping' command.
Traceroute
-
The IPv4 Traceroute field will run the Linux 'traceroute' utility.
-
'traceroute' tracks the route packets take to reach a host.
-
The parameters are the same as those taken by the Linux 'traceroute' command.
-
Run 'man traceroute' for details.
