Network Utility netstat does not respond

Question

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 utilitySoftware  Mac OS X Lion 10.7.2 (11C74)Marvell Yukon Gigabit Adapter 88E8053 Singleport Copper SA:  Name:          ethernet  Type:          Ethernet Controller  Bus:          PCI  Vendor ID:          0x11ab  Device ID:          0x4362  Subsystem Vendor ID:          0x11ab  Subsystem ID:          0x5321  Revision ID:          0x0022  Link Width:          x1  BSD name:          en0  Kext name:          AppleYukon2.kext  Location:          /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleY ukon2.kext  Version:          3.2.2b1

Update: It did respond but very slowly( 1min), similair to command linecmd : netstat -rGUI : Display routing table informationI guess the question is, is the speed (aprox 5 min) of response normal?&gt; time netstat -rRouting tablesInternet:Destination        Gateway            Flags        Refs      Use   Netif Expiredefault            192.168.2.1        UGSc           22        0     en0127                localhost          UCS             0        0     lo0localhost          localhost          UH              3   558048     lo0169.254            link#4             UCS             0        0     en0192.168.2          link#4             UCS             4        0     en0192.168.2.1        &lt;xxxxxxxx&gt;    UHLWIi         32    11123     en0   1096192.168.2.11       localhost          UHS             0        0     lo0192.168.2.13       &lt;xxxxxxxx&gt;    UHLWIi          6   816330     en0    343192.168.2.14       &lt;xxxxxxxx&gt;   UHLWIi          0        0     en0    690192.168.2.16       &lt;xxxxxxxx&gt;   UHLWIi          5   393491     en0   1015Internet6:Destination        Gateway            Flags         Netif Expirelocalhost          link#1             UHL             lo0fe80::%lo0         localhost          UcI             lo0localhost          link#1             UHLI            lo0ff01::%lo0         localhost          UmCI            lo0ff02::%lo0         localhost          UmCI            lo0real          4m40.053suser          0m0.003ssys          0m0.008s

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&#x27;s DNS server addresses is to use Google&#x27;s: 8.8.8.8 and 8.8.4.4. - see https://developers.google.com/speed/public-dns/?csw&#x3D;1
