I have a problem I can't find an easy answer to in the man entries etc: I
have a networked Debian box. When the network is up, it uses the network
router as its gateway to the Internet. When the network is down (most
evenings) there is a dial-up connection via external serial modem. I can
get the dialler to connect via dial-up, but none of the software will use
the modem connection - not mailer, not newsreader, not browser. I don't
want to remove the network gateway (it's broadband): what do I have to do
to get my box to use the gateway if it's open and the dial-up connection
otherwise?

Please point me in the right direction ... thank you

You need the pppd to replace the defaultroute (which uses your local
router) by the default route using the dial-up connection. All you need
to do is to add a line

replacedefaultroute

to /etc/ppp/options or /etc/ppp/peers/yourprovider

Hint.  Easy answer could be find with

dpkg -s <packagename> |grep '^Depends\|^Suggests\|^Recommends'

AFAICG the defaultroute is set automagicaly, but all the stuff say "Host
not found"?  If I guessed right...

Consider 'resolvconf' package.  I wouldn't say that packages, such as
'pdnsd', "Sugests", they really "Depends" on 'resolvconf' to strap
correctly when a link comes up.
