[Cooker] [Bug 5244] [lisa] Lisa bombards the net with packets
http://qa.mandrakesoft.com/show_bug.cgi?id=5244 --- Additional Comments From [EMAIL PROTECTED] 2003-13-09 22:43 --- ppp is no more touched by lisa (not a single packet generated by lisa - checked with tcpdump). Thanks. -- 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: ASSIGNED 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 will repeat the test with GPRS later today. -- 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: ASSIGNED 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.

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.

http://qa.mandrakesoft.com/show_bug.cgi?id=5244 --- Additional Comments From [EMAIL PROTECTED] 2003-10-09 21:30 --- Eric: No, I did not see the lisa being a CPU hog, but this could be because the interface used was a slow one. I don't know whether I had one or two of them, but one stop was enough to stop the flood. As said, I can do some more tests on the weekend, but not now - sorry. -- 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.

http://qa.mandrakesoft.com/show_bug.cgi?id=5244 --- 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. -- 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.
