1. Probably no-one, if you have good password and don't use it anywhere else, but at least I really like to have some security
2. Because I need it?
3. At least I have my server and desktop computer connected to internet all the time so it's pretty much impossible to disable access to everyone completely.

Doesn't sysklogd slowly fill up rootfs space with the logs, though?
My year old laptops auth.log is currenly 43.0 KB so it probably clears it automatically.

Yes it seems to remove over week old entries.

I don't think that tail is heavy or is it?

Do you like the shell-script that much? What about a C program doing this? Much faster and lower ressource consumption?

I just ported the script I did for my computers. I have always thought that tail is pretty light application, but please show me otherwise. C application would be lighter, but I don't think its necessary.

I was just curious. Take a look at how to limit cpu usage (signal.h and SIGSTOP and SIGCONT and dbus with C is pretty much the same. There is a great wiki about it.

No, definitely not. I think it is more so the fact that the CPU would never be in an idle state because 'tail' defaults to checking every two seconds, so the CPU will be constantly switching between going idle and then waking, so it could be a battery drain.
I'm no expert in this area so I don't know; maybe a cron job would be better which externally executes the script (but not using the '-f' switch).

Nice job anyway!

What about using Inotify for watching the log (or some other file that changes when users log in) ? Provided Inotify is available on Maemo, of course.

It's a good script to run along Kippo. The only thing missing is a sound notification after every failed auth attempt...
