Demand dial doesn't raise ISP connection

Hi,

Wonder if anyone could help please.  I'm running RedHat 6.0 (kernel 2.2.5),
as it comes straight out of the box, and diald 0.99.1 (tried 1.0 but
couldn't make it do anything - probably my fault!).  When I use the front
end tool dctrl on a fifo I can control diald making it raise and lower the
ISP
connection (ISP is BTOpenWorld, U.K. using CHAP authentication) or I can
force the link up and down.  However with the daemon just sat there waiting
for a request such as ping, traceroute or web-browse it carries on just
sitting there doing nothing.  I thought it could be a SLIP problem but lsmod
shows slip is in the kernel and sl0 devices appear on the routing tables.
I'm trying to set this up as a router for a network that is Windows oriented
as I find that the Win2k server RRAS & NAT protocols are just rubbish.  When
I manually raise the link our network users are very happy :-) so it should
be great if I could only make the demand component work.

I have included my diald.conf file:

# Standard filters

The file /etc/diald/diald.connect does this:

/usr/sbin/chat -v -T <BTOpenWorld number> -f /etc/ppp/chat-default

The file /etc/ppp/chat-default does this :

TIMEOUT 5
ABORT "BUSY"
ABORT "ERROR"
ABORT "NO CARRIER"
ABORT "NO DIAL TONE"
ABORT "NO DIALTONE"
ABORT "WAITING"
"" "AT&F1"
"OK" "ATDT\T"
TIMEOUT 45
"CONNECT" '\c'

I'm assuming that the previous two files are irrelevant information as I can
force the link and it's O.K.

Routing information:  the following come from netstat -i, route and ifconfig
in the waiting state (listening for a request) and when I force the
connection using dctrl (connected) ....

The proxy slip interface, sl0, appears to be there and is converted to a
physical ppp0 upon connection.  This is probably a trivially stupid question
based upon my lack of experience in linux in which case I hope that there's
a simple answer?
