[Samba] SOLVED Re: NT_STATUS_CONNECTION_REFUSED, again!!!

Mon Mar 2 00:48:09 MST 2015

Hai Bob ( and Rowland ), 

Great work here,.. Bob. what was the cpu your useing
Can you post the output of cat /proc/cpuinfo and send it to me. 
I'll try to add something in the script to look for what cpu is being used. 
and i'll add the slowdown in it. 
I'm running on a AMD Opteron 4386, 3.1 Ghz, so thats why it always works for me.
I'll go test this also on a few slow machines. 

Greetz, 

Louis
