------- Additional Comments From [EMAIL PROTECTED] 2003-10-09 23:24 ------- > IMHO, this (class A network for no specific reason) is bad practise ... Fully agree. Unfortunately many do this - my GPRS provider (no way to change this), LAN side of my ADSL modem/router (maybe hackable but when I tried, other things acted weird - Thomson Speedtouch 510i)... Note: I did NOT have both active at the same time when I tried :-) > what interface name is your GPRS? ppp0. It's a plain old pppd, just running over bluetooth instead of the serial line. > I will have a new initscript for you before the weekend, I would like you to test it OK, many thanks. > (and if you have a LAN at home, see what the advantages are). I have only a small LAN connecting a desktop (Debian unstable), a laptop (with the Mandrake I wanted to give a try) and an ADSL router. I can install the lisa also for the debian and see what it does there. > Nothing else (ie WAN) would be affected, since that crosses the subnet boundary At least the case of an ADSL in the bridged mode (i.e. where the linux box itself does the PPPoE and routing) should be investigated. If the lisa sees it as a local ethernet interface, the problem can probably bite here too. -- Configure bugmail: http://qa.mandrakesoft.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------- Reminder: ------- assigned_to: [EMAIL PROTECTED] status: NEW creation_date: description: 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
