I was running tethereal (CLI version of ethereal), and found several packets like that 6846.050317 212.x.y.z -> 10.11.1.24 HTTP HTTP/1.1 200 OK[Unreassembled Packet (incorrect TCP checksum)] 6850.329578 212.x.y.z -> 10.11.1.29 HTTP HTTP/1.1 200 OK[Unreassembled Packet (incorrect TCP checksum)] 6850.331642 212.x.y.z -> 10.11.10.2 HTTP HTTP/1.1 200 OK[Unreassembled Packet (incorrect TCP checksum)] 6851.551598 212.x.y.z -> 10.11.1.24 HTTP HTTP/1.1 200 OK[Unreassembled Packet (incorrect TCP checksum)] Who writes this { [Unreassembled Packet (incorrect TCP checksum)] } ??? Any meaning for that ?? Is it a faulty network card ?? Regards -- Mohamed Eldesoky www.eldesoky.net
