Hi again,
I made a few corrections to my previous mail but the basics are the same.
I think van Galen pb and mine could be related.
I have a strange phenomenon to submit to the community : a crash. :-)
The curiosity is that it never happens with a PC I have been (Celeron 766)
owned for 1 year.
And occurs systematically (but it used to work rarely) with 2 other PCs,
PIII based, that runs over 1Ghz. One is a compaq evo300, the other one a
Flex.
The main differences between the 2 families of PC are, at least their age (a
few months difference) but also the type of Pentium III and the chipset.
The one (Celeron 766) on which it works without any problem is a Coppermine
with 128 k L2 cache the two others are full PIII with 256k L2 cache.
Celeron 766 has a SiS5513 chipset, both others have Intel 815.
I made a try while reducing the CPU frequency of the Flex to 667 Mhz.
It worked the first time I did it and then always crashed at the same
frequency.
The kernel is 2.4.18 (compiled for i686) patched with super-freeswan-1.98b-kb5
and bridge-0.0.7.
The crash rises up in pluto when it receives a IKE exchange following an IKE
initialization. It never happends on a passive Pluto. It never happens
running without pluto (and making ping, telnet, ssh, etc).
Tests were made with a system on a CDROM making changes impossible.
I have a evo300, running in Spain, that worked correctly during 3 full days
even when rebooting and suddenly ... systematically crashed with the same
CDROM.
---------
The ksymoops speaks about a br_nf_post_routing_finish and ip_frag.
Could it be a pb with ip fragmentation ?
I canceled the rules in postrouting chain : no way.
I loaded ip_conntrack_ftp : no way.
So, you'll find here the end of the results of ksymoops.
If you can do anything (other than switch me to ebtables) it could save my
life :-)
Thanks,
db
