I am unable to obtain a response from netstat on 3 of 4 options within the network utility. I obtain comprehensive stats but all others see no feedback. I see netstat command line will respond but do not see corresponding entry in network utility

    Update:

     

    It did respond but very slowly( 1min), similair to command line

     

    cmd : netstat -r

    GUI : Display routing table information

     

     

    I guess the question is, is the speed (aprox 5 min) of response normal?

     

    > time netstat -r

    I final tracked this down to the DNS settings on my network tab on the MAC. Previously the only entry was my RG. I hard coded the DNS entries from my ISP and command started to respond normally. I have also seen a improvement in my Apple Mail and IMAP GMAIL. It was having a 15-30 delay which now as droppped to 2-3 secs.I guess with this solution I run the risk DNS IP changes will cause issues but I suspect that is low probabiity. Not sure if the MAC can auto populate the DNS servers. I will have to do some research.

    Thanks for this - had similar problems and your solution worked for me too. One - potentially longer-lived - alternative to specifying your ISP's DNS server addresses is to use Google's: 8.8.8.8 and 8.8.4.4. - see https://developers.google.com/speed/public-dns/?csw=1
