ip-up scripts not running

[Alisdair McDiarmid <alisdair@letdown.demon.co.uk>]

I've got a script in /etc/ppp/ip-up.d to run fetchmail on connect,
but it doesn't appear to be run - running `ps aux | grep fetchmail'
just after connecting shows nothing. I think the permissions are
correct - I'm in group dip, and the permissions are:

[root%letdown /etc/ppp] # ls -l ip-up ip-up.d
-rwxr-xr-x   1 root     dip          1452 Jun 13 22:53 ip-up
ip-up.d:
total 5
-rwxr-xr-x   1 root     dip            84 Nov  7  1998 exim
-rwxr-xr-x   1 root     dip            62 Jun 10 08:46 fetchmail
-rwxr-xr-x   1 root     dip           792 Jan 15 12:15 isdnutils
-rwxr-xr-x   1 root     dip           567 Oct  8  1998 slrn
-rwxr-xr-x   1 root     dip            12 Jun 10 14:23 wibble

The /etc/ppp/ip-up.d/fetchmail file is just:

/usr/bin/fetchmail --invisible --fetchmailrc /etc/fetchmailrc

Also, I connect several times during a session: is there a way to
start fetchmail from ip-up only if it's not running already?

TIA,
