Manually flush DNS Cache

[tsiemers1]

Is their an option in command line to manually flush the DNS cache?  Otherwise does disabling it and re-enabling flush the cache?

If you are asking about FirePOWER Management Center then you can flush it from the cli using shell commands and restarting the daemon.

/etc/rc.d/init.d/nscd restart

That should do it.

I'm not sure if the system setting for DNS Cache in the GUI will accomplish the same thing.

I had to also add sudo to the beginning of the command
