Many thanks for your reply.  I assume you mean that I should set up an
alias for ppp0.  The following modules are loaded when I have a dial up
connection:-

To be honest I am a little puzzled as to why linesrv _needs_ to poll 
ppp0 at all when the link is idle as opposed to during start up and shut 
down.

Network configuration is handled by a RedHat utility which offers a boot
activation option (with demand dialling) for ppp.  This is intended for
fixed IP links.  I tried to use it in conjunction with dynamic IP
resolution and it locked my machine up during boot.   I would expect
that this will pre-load the necesary ppp modules but making it work with
dynamic IP looks like trouble.
