Hi guys,
 
 anyone experienced this: When I'm doing ping and capture UDP packets
(I'm usind UDP encapsulation) with ethereal there's incorrect udp-
checksum. I've tested this on different machines and it appears only on
FC2 with different NIC. My questio is: How is ethereal computing the
correct checksum? Is the ethereal one computed using libpcap or is it
vice versa?

Thx for any info

Radek
