Hi!
First of all I want to thank all you guys for your efforts in LRP and
it's spinoffs. It's really great. I made my first steps in Linux in when
I wanted to share my cable connection with my flatmate via a dedicated
Linux Masquerade box in the december. My first setup with Suse took 3
weeks to get to work, I later switched to RedHat (took me 2 days) then I
switched to debian (one long evening). Then my friends started to ask me
about setting up firewalls for them, so I configured a EigerSteinBeta2.
(4h first time at home). When I set it up for my friend it took us 2.5
hours, but 2h were spent waiting for his provider to get the connection
up again (they unfortunately oversell heavily and give a lot of
trouble). Next step will be a VPN using IPSEC configuration which I will
then duplicate for a couple of different friends that want to share
their Windows-LANs ;-)
Now my problem:
I also managed to configure my EigerStein to use a modem dialup setting
with demand dialling via pppd (it seems that this is not really a usual
setting for a router ;-). However dnscache gives trouble since it
doesn't like to start at bootup without the EXTERN_IP set (of course a
different IP is assigned each time connection is established). I tried
to start it later on manually setting the IPSEND to the current value.
It just waited for a long time however (maybe wrong user). Is it really
necessary for dnscache to know it's extern ip for querying or can I also
set it to something like 0.0.0.0?
Second question:
There is a server running IMAP in my local net. I would like to
configure it to flush out exim's mailqueue and start fetchmail each time
the modem's link goes up (ie. ip-up is run from pppd). Is there a ssh
client in the sshd.lrp package (I don't think so it didn't find the
command). So I thought of this "hack". I have xinetd listening on a high
port on the server and each time the firewall goes up it sends a SYN
package to that port, making xinetd start a script to do the job. It
even works when I telnet from the server. It's just that I don't know
how to practically generate the SYN packet on the router (I don't really
want to install telnet, for obvious reasons), but I guess you will. If
you have another (less freaked out idea) on how to achieve the same
thing, ideas would be welcome of course.
thanks
Fabian

chello, ask me as well.
