how can a program tell if ppp-on succeeded

I'm using Redhat 5.1.
I have pppd working correctly.

I'm writing a program that starts up a ppp link via the /etc/ppp/ppp-on script file.

The program needs to open up a socket with the remote computer after the ppp link is established.

Does anyone know of a "good" way to determine if the ppp-on script succeeded in establishing a ppp link?

Do I use the connect-errors file?
Do I use the ip-up.local and ip-down.local files?
How long do I wait to determine a failure?

The ip-up and ip-down scripts are the official way to do this, and should work well. However, they do not provide a way (that I know of) to run a script on connection failure. If this is important, the approach I would use is to hack out a shell script that waits until either ip-up gets run (by looking for the presence or absence of a flag file, perhaps), or until the ppp-on script no longer appears in ps ax. I would tend not to use a fixed timeout interval, because you really never know if pppd is still trying or has failed. But you can be sure that it's failed if it exits.

Thanks I really just wanted a second opion.  I'm using "/bin/touch PPP.UP" and "/bin/rm PPP.UP" in ip-up.local and ip-down.local.  I then check for this flag file.

Thanks again.
