Without knowing more it is difficult to help any further. Hopefully the sites I listed earlier give him a good place to start. Years ago, when I was working at Shaw, I wrote a php front end to a number of common *NIX utilities to help troubleshoot weird problems. It occurred to me on the way home that this is one approach to tracking down the problem. Have a web front end to control the traffic generating apps that are at his home/office, and a laptop to log the data in the field (ssh can be a pain over high latency links, its why I wrote the php front end in the first place). > Now, take what I've said with a grain of salt.
