------- Additional Comments From [EMAIL PROTECTED]  2003-10-09 21:07 -------
Sorry, I have other things to do now, so don't expect further testing from me
until weekend. I investigated a bit and my GPRS provider indeed uses 10.0.0.0/8
too :-(

Anyway, the problem has nothing to do with ppp. It can be eth where it hurts
(e.g. non-flatrate ADSL), it can be wlan, whatever. To try to guess thing based
on the interface name is also not a good idea.

Lisa seems to flood the whole network, regardless of what the network is. If the
netmask is 255.0.0.0, it will probably send at least 16 millions of packets. I
don't know what the lisa exactly does, I never used it and it was never
installed and activated by default on other distros (I am trying Mandrake for
the second time, but am a long time Linux user). I just don't think this is a
sane behaviour and should IMHO not be present out of the box, if at all. Imagine
a large network where every machine does the same. Imagine that they are on a
slower connection (wlan) and they all start at the similar time (people booting
the machines in the morning).

I agree that this is probably a problem with lisa itself and not specifically
with Mandrake. I will most probably file an upstream bugreport on the weekend.

I have the LAN at 10.0.0.0/8. tcpdump shows that the lisa tries to do an ARP
request for probably all addresses in the network and literally bombards the net
with packets. I don't know what this might cause on a large network. To add to
this it continues these probes even after the LAN interface goes down.

This can also result in a costly problem. The following happened to me:
- I configured my notebook for GPRS over bluetooth
- I removed the LAN card from my notebook so it does not interfere with the
experiments
- I brought a PPP connection up
- The defaultroute was set to ppp0
- The lisa continued to send packets
- They all travelled to the phone, generating paid traffic :-(

The distribution is Mandrake 9.2 Beta 2

Proposed resolution: don't enable the server by default and document this
problem somewhere
