on FreeBSD 5.3 I am using ppp in interactive mode with a ppp.linkup script
to perform some commands (sendmail and ntpdate):

!bg sendmail -L sm-msp-queue -Ac -q
!bg ntpdate ptbtime1.ptb.de

In man ppp I have seen:

All external commands (executed
via the "shell" or "!bg" commands) are executed as the user id that
invoked ppp.

So the only way for a normal user to run this commands successfully in ppp.linkup are per
sudo ppp or is there another chance to run these commands?
