Description shishz 1999-10-13 19:22:00 UTC

After an upgrade from 6.0 -> 6.1, I compiled my own
2.2.12 kernel without ip_always_defrag.

I received a /proc/sys/net/ipv4/ip_always_defrag is missing
cannot control ip defragmentation and kudzu was marked
off as [failed]...

I made the following change to /etc/rc.d/init.d/network:
not sure if this is the correct way to do this but it
worked out ok... (initscripts-4.48-1)

There may be something more going on, since I didn't
expect /etc/rc.d/init.d/network to cause
/etc/rc.d/init.d/kudzu to fail.

Comment 1 Bill Nottingham 1999-10-13 19:37:59 UTC
The message is OK as it is, I would think; it's just stating
a fact.

Most likely kudzu is failing because of something else.

What happens if you run it at the command line?

Do you have any ide-scsi devices?

Comment 2 shishz 1999-10-14 16:28:59 UTC
Ah, your right... I backstepped what I had done and found that kudzu
seg faults if CONFIG_FIREWALL=y on my machine.

I don't use the firewall or have any masquerading on this machine
so I don't know if this is a bug in kudzu or not.

Two 3c509b nics, pentium, no ide-scsi devices, no scsi.

Everything is fine when I recompiled with config_firewall off.

Here is a bt if your interested:

Comment 3 Bill Nottingham 1999-10-18 16:28:59 UTC
CONFIG_FIREWALL?  There's nothing in kudzu that should
depend on that one way or another.

Unfortunately, the binary you have doesn't have debugging symbols,
so I can't figure out where it died at.

Comment 4 Bill Nottingham 2000-02-08 22:48:59 UTC
(Apologies for the extreme delay)

Did you compile your kernel without CONFIG_PNP_PARPORT? This
*will* cause a crash with the kudzu that shipped in 6.1,
and it's since been fixed.

Comment 5 shishz 2000-02-10 16:13:59 UTC
Thanks, that was it...
