Re: [OpenIndiana-discuss] Network inordinately slow: help devising fault-finding procedure needed!
Hi Hans, I'd start with looking into kstat output for e1000g*. HTH Michael On Fri, Feb 22, 2013 at 2:57 PM, Hans J.

Hans, are both interfaces connected to the same hub/switch? On Fri, Feb 22, 2013 at 2:57 PM, Hans J.

can you try to traceroute -n 8.8.8.8 it might well be a DNS problem On 22 February 2013 14:06, Michael Schuster michaelspriv...@gmail.com wrote: Hans, are both interfaces connected to the same hub/switch?
