ss used in quick_start.sh not available on MacOS

[geekysquirrel]

When running FlowKit via the quick_start.sh script, ss -tuna is used to check for the status of FlowMachine.

Version
c4dc74f

To Reproduce
Steps to reproduce the behavior:

1. Run quick_start.sh on MacOS

Expected behavior

[...]
FlowDB ready.
./quick_start.sh: line 141: ss: command not found
[...]

Additional context
A quick search revealed that ss (a netstat replacement included in the iproute package on linux) is apparently not included in MacOS, allegedly because of dependencies on the linux kernel. Workarounds exist.

Hmm. It should already be using a workaround if ss is not found - the script actually runs (ss -tuna || netstat -an).

So either we're just not suppressing the error message from attempting to use ss (and actually the script carries on fine), or we're not handling the error properly so the workaround never gets tried. Either way something could do with fixing, but with different degrees of severity.

Does the script go on to output "FlowMachine ready" after the error message?

[geekysquirrel]

Yes it does, eventually.
