Hi, I hope this is the correct list - if not, please tell me which one is. SuSE 8.1 with all updated .rpms applied postfix is the e-mail client but is essentially unused because I do everything with mozilla. *the setup* eth0 points to the internal network (fixed IP addresses) eth1 points to the net, the IP address is dynamic. (I also have a second profile where the net is DSL, that goes via eth1 as well and always works) SuSEFirewall2 is active and blocks all services from outside while letting everything inside through (Samba has 'bind interfaces only' set, nfs is inactive, very few services are installed anyway) *the problem* When I go online, things normally work for a few (maybe 5) minutes but then I start getting the following firewall message: Feb 1 18:32:56 newred kernel: SuSE-FW-ILLEGAL-TARGET IN=eth1 OUT= MAC=01:00:5e:00:00:01:00:50:57:00:64:45:08:00 SRC=10.20.0.1 DST=224.0.0.1 LEN=32 TOS=0x00 PREC=0x00 TTL=1 ID=8723 OPT (00000000) PROTO=2 I can then (I believe there is a link here, although it could be a coincidence) no longer access the net, or the e-mail server, or the dns servers or anything else. De-activating the firewall does *not* help. Recently postfix (the updated .rpm) also went haywire so I set the mail server to localhost and that seems to have taken it out of the equation. *history* This originally worked for a couple of weeks (cable is new here). I installed the updated dhcp-client-3.0.1 version no problem I noticed that dhcp-base-3.0.1 had a new version and installed that. the problems seem to have started then. I have just reverted both dhcp-base and dhcp-client, maybe that will help. They *are* security fixes though. *The workaround* I kill the dhcpcd daemon (also the new version, but installed earlier) and then do a 'dhclient -1 eth1'. This fixes the problem, although it did not always help until I reset the postfix mail server to localhost. Does anyone have a clue what could be going on here? My suspicion is that dhcp-base is the culprit. thanks for any hints Andrew -- opinions personal, facts suspect. http://home.arcor.de/36bit/samba.html
