Hi all, I've just configured dial-on-demand user-mode ppp and it's excellent! Works really well. I've got just one problem: the link will be going down and up intermittently, as it's dial-on-demand and I've set an inactivity timeout. Whenever the links becomes active again, I need to run an external program. The "Pedantic PPP Primer" (http://www.freebsd.org/tutorials/ ppp/ppp.html) and the manpage (ppp(1)) don't say how to do this. Looking at /etc/ppp/ppp.linkup.sample, the "pmdemand" entry has a statement as follows: ! sh -c "/some/program/or/other &" This presumably executes the program in quotes (as the comments in the file say it does). Now, what I'd really like to know is (a) What are the exact syntax/symantics of this statement? (b) How does it differ from the "shell" command available from within ppp's prompt? That is, could I also use shell "/some/prog" in my ppp.linkup entry? Thanks in advance for any help. Bye, Mike <mike@NetworX.ie> ---
