I think one passive way is to use "screen" ,and detach the "screen" when you donot communicate with it. It can at least keep you program running in the background.
This will not help if you need to have continual communication with your console.

On my laptop,i use ndiswrapper as the wireless module,the wireless lancard so named wlan0. It's never stopped or restarted no mater how weak the signal was.

Sounds good, do I need to edit /etc/init.d/sshd to do that, or is
there a better way?

What about sticking 'rc' in the crontab? No good?

What's wrong with setting RC_STRICT (?) appropriately, it's what it is
for. With the right setting, net.lo will satisfy sshd.

Thank you, I do think RC_NET_STRICT_CHECKING is what I'm after.
