I have seen this referred to before on the adsl list, and solutions offered involving various keepalive scenarios. one suggestion is to use spinner http://www.laffeycomputer.com/spinner.html "Spinner is an anti-idle program that displays a little "spinning" ASCII character in the top left corner of your terminal. To make this effect it cycles through punctuation marks like this " - \ | / - \ | / ... " (try it to see). By default the character is drawn in inverse video (or your terminal's equivalent). But you can turn this off with the -i switch. In spinner mode Spinner supports any terminal capable of handling VT100 style escape codes. In null mode (-n switch) Spinner supports any terminal. In null mode there is no visible output, and Spinner will not interfere with your terminal or scrollback. If you find the little spinner in the top left corner to be distracting use null mode. (-n switch). Spinner is useful for keeping telnet and ssh links from dropping due to inactivity. Many firewalls, and some ISPs drop connections when they are perceived as idle. By having spinner running the server is constantly sending a tiny amount of data over the link, preserving the connection. As of version 1.2 Spinner can also be activated with the -n switch so that, instead of displaying a spinner, it simply sends out a periodic null character to the terminal. This achieves the same anti-idle benefit without disturbing your screen. But it lacks the coolness factor of a little spinner in the corner of the terminal..." The other I have seen is to set ProtocolKeepAlive n (where n is a number of seconds) in ssh_config (system wide in /etc/ssh/ or per user in ~/.ssh/ > > I'm wondering if mtu might be a problem but I don't see why it should be. shouldn't be - what adsl connection are you using? sometimes adsl is just flaky and will drop connections. you should also look at screen so that your session does not disappear. also, as the spinner author said, firewalls and routers sometimes drop idle connections, this includes some NAT implementations. > > I'll have a look at that nocat thing :) > > Cheers Don
