First, I'll pick on your subject.  Nothing wrong with it but what 
happens if you use the same system to scp a file internally?  Same for 
doing something like opening something like the SWAT (samba web 
administration tool) on another box or some internal web server?  Have 
you tried just letting ping run for a while?  Also, try the same actions 
through the loopback interface (e.g., open SWAT on this box through 
127.0.0.1).

If "things" stop after a consistent (time or byte count) point, chances 
are that something is causing them to stop.  If the stop point is 
random, you may have a hardware problem.  ifconfig *may* provide some 
useful information (like error count, dropped packets, etc.).  If things 
are "normal" internally, chances are you've got a firewall, router or 
something that is stopping network activity for some reason.

You never know what can cause problems.  A while back my internet 
service started degrading.  It finally got to the point where I couldn't 
get out at all.  I use point-to-point wireless and my ISP said they had 
a good signal to my antenna but I couldn't "reach" the antenna box.  
They finally sent a service tech out to check the problem.  Turns out a 
squirrel had chewed through part of cat5 line to the antenna.  They 
replaced the line and I coated it with hot sauce (Cold Cap to be 
exact).  Hopefully, the neighborhood squirrels don't like spicy food.

Cheers,
Dave
