Re: Unwanted routing table entries
-----BEGIN PGP SIGNED MESSAGE-----
Hi Avery,
The sl0 device entries are set up by the diald package, which task is to
automatically dial up the line to your ISP if needed. This should be no problem
with your dialin script. Try setting another IP-adress (something like
10.0.0.1/10.0.0.2) for your local/remote. If afterwards route doesn't show the
route, simply add these entries with some name like "isplocal" and "ispremote"
to your /etc/hosts file. The parameter "dynamic" has to be activated in
/etc/diald/diald.options an "ipcp-accept-local", "ipcp-accept-remote" and
"noipdefault" in /etc/ppp/options to adjust these ip's to the ISP's
IP-adresses. If you want the automatic dial in to work, there is no way in
removing the default route entry, otherwise you can delete the entry
"defaultroute" from the /etc/diald/diald.options file.
Both sl0 entries are dummy entries. When these devices are adressed, diald will
set up the serial line and configure it in a way, that the modem is added as a
network device to the system. The default route entry is needed, because this
is the one entry where all frames, for which no matching local adress could be
found will be sent through. So any time you try to address some internet
adress, this frame will be sent through this route and diald will be able to
set up the line. If you remove the default route, you will get a "unknown host
..." error in this case.
Hope this helps
Dieter
