Hello!
|
|
after some tweaking and testing I have solved the problem with
|
|
the checksum errors. ( Apparently and hopefully, up to now no
|
|
more error messages)
|
|
Because of the slowness of my computer (thanks Fritz!) I have done
|
|
two things:
|
|
a) changed the IRQ from 15 to 5 for the Teles card -> the Teles is now
|
|
on the Master controller
|
|
b) got irqtune and changed the priority for the teles card to maximum
|
|
in favour of disk. ( irqtune 5 )
|
|
With this two changes I was able to cure my errors from HiSax:
|
|
MASQ: failed TCP/UDP checksum from xx.xx.xx.xx!
|
|
for the Teles-driver the following error messages:
|
|
Teles: HSCX RDO mode=2
|
|
HSCX B EXIR 40
|
|
Possibly the first solution would be sufficient, but what the heck,
|
|
don't touch a running system.
|
|
|
|
The original message is included below and yes I know my reply address
|
|
is wrong and should be heiling@online-club.de. I will fix
|
|
this really soon now, if my new Debian CD has arrived.
|
|
Thanks
|
|
