/etc/hostname.* is only executed once when the system starts. The PPP disconnect/reconnect is handled entirely by pppoe(4)--well, sppp(4) really--in the kernel. There is no callout to the userland available. It may be possible to use ifstated(8) for this. I haven't tried that, but it's where I would start looking. > Is the culprit here something along the lines of not (re)configuring the > interface with ifconfig up/down (in which case the script would run), Note that ifconfig down/up will not run /etc/hostname.* either. -- Christian "naddy" Weisgerber [email protected]
