Hello,I am looking for a way for a Linux machine to tell when I return home. My idea is that my iPhone will always do an mDNS announcement when it joins my home wifi. So I'm looking for a way to watch for mDNS announcements and perform and action if the right one is seen. Obviously the avahi-daemon is watching these all the time and updating its cache, so I was thinking that there might be a good place to start. However the only command line way I can see to get to the avahi-daemon cache is to send a SIGUSR1 to get it to dump to /var/log/syslog. Then I can look at the timestamp to determine the last time it registered and compare with now. That seems quite ugly though, and I don't like the idea of continually dumping to syslog.<br clear="none">
So is there a way to make it more event driven with the avahi-daemon? I think from looking at the D-Bus API that might be the way to go?If it is the right approach, I would appreciate it if someone knew of a related chunk of source that I could use as a starting point.<br clear="none">
Thanks!Jonathan<br clear="none"><br clear="none"></blockquote><div><br clear="none"><div class="yiv3978991876gmail_extra">Write a small program that uses the Avahi API.
