Hi all, is there a way of determining whether an interface is connected (particularly tun0) without trying to send something (e.g. ping packets) across the interface ? What I want to do is find out if the interface is currently connected and iff it is then download mail from my ISP. The situation is that I run ppp -auto and download mail twice a day out of cron. The PPP connection is also used intermittently for other things (WWW browsing etc.) and I would just like to periodically check to see if I am connected and download mail if I am.
