    Ya know, I did that; I got a Belkin at WalMart for about $40. It
works pretty well, but as always when you buy something they obscure all
the 'goodies' that are possible to make it market-ready.

    That's why I want to eventually make a Linux box my router/firewall.
Then I can get a 'logwatch' from it each night, set up QualityOfService
so the Packet8 telephone doesn't get trashed when I'm in a BT download,
that kinda  thing.

    There's a "keepalive" option in ssh; I'll bet that's not set, and
it's pulling down the connection, 'cause it thinks you've walked away
after an hour or so.

    If you really want to have some fun, look into eBay for "pc104
- -keyboard".  That's where you'll find some really interesting hardware
that's stackable, perfect for routers/firewalls, including those who can
act as a personal weather station for just another $30.

    This PC104 thing is like what the PC would be, if it had to be
designed in an oatmeal box; the boards are something like 3.5"x3.5".
They stack, so you can do all kinds of neat things, including
supercomputing, if you want to.
