Dear List!
I use SuSE 7.3 with latest updates loaded.
I´ve discovered a problem with MS-VPN (ppp).
When some Win98 PC connect to the VPN on the firewall, the firewall will
stop (DOS) immediatly. Its hanging fully so that i can only switch the
power off. No reaction on Keyboard.
This problem is specific to 2 PCs which are owned by an related company.
When I try to connect to VPN with clean installed Win98 it´s working
fine.
The problem is occuring EVERY time, when one of the 2 PCs try to connect,
and ONLY then.
I sent you some part of the system messages.
Can someone of you Gurus out there tell me whats going on and how to
protect against that??
kind regards
Josef Fuchs

What we have here is a Kernel oops. Your squid/ppptp did something stupid and died, tearing the system down (which shouldn't happen too often). How many users do you have? D'you have lots of traffic? Unfortunately you didn't state your kernel (2.2? 2.4?)/squid/ppptpd versions and your machine specs; also, it seems that there's an auth problem with one of the Win98 boxes (notice the CHAP error in your log excerpt).
Hi Josef, I had the same problem. Everytime I had lot of traffic to samba my server died. In my case it was a mainboard problem. I resetted it (it was brandnew) and then it even worked when I put 2GB's files on it. Ciao ;-) Robert Rottscholl - DE Boris Lorenz wrote:

Ciao ;-)
In my small home network (5 pc) I got a similar problem. When a PC (Win98SE) starts to send out too many bytes the network (ethernet), the eth1 interface of the samba PDC dies and I have to restart it manually. It does not happens with another pc which has the same version of windows and the same NIC. I have never understood why this is happening. It is not samba related because the other samba computers does not have the same problem. Praise

Got the same. Saw something on the errorlog console and did simply hdparm -d0 /dev/hdX to disable ide-dma if this work you've to edit /etc/rc.config and set ide_dma to "no". You can set down the network-adapter speed by parameters in /etc/modules.conf too e.g. options 8139too media 3 - set's up 10MBit Network (need re-boot/init) ...and yes - its not security related Michael Appeldorn
