Hi, I hate it when I miss something in a post and feel the need to reply twice...
If all you're looking for is to know when the server is back on line, start an xterm do a `ping server.domain` when the server comes back you'll start seeing the echo replies fly by and you can reconnect. BTW the magic keys to get out of a hung ssh session due to network collapse is ~& you may need to hit return before as well as after this sequence. This puts the session into the background, and is also handy to get a local terminal back while maintaining tuneled ports. -Jon
