[TriLUG] Web Site access testing

[Roger W. Broseus via TriLUG]

Brian,

First, I'm no expert on such problems.

Certainly does sound like a potential network problem to me. But, I was not 
clear about your last statement: can you SSH "into" the troublesome location.

I had a seeming network problem and looked for diagnostic tools. The only one 
helpful was, sadly a Window$ application: Ping Plotter. A free full, trial 
version is available; later, the limited kicks in and is still useful. It 
helped narrow down where in the chain the obstruction occurred. The more I 
think about it, the more I think the block is on the receiving end.

IF you come across a helpful Linux tool, let us know.
