Actually, most distros like ubuntu began removing traceroute in favor of 
mtr instead as default.

Why I don't know, I'll give up 68k for the binary as it's useful still.  
Problem is mtr isn't very suitable for leaving the output on screen for 
you to cut and paste without invoking specifically, but otherwise is far 
superior.

Those familiar with pathping under windoze will appreciate it, sort of 
that on steroids.  Know and love it as the modern traceroute, as it 
usually tells me easily when cox is having issues.
