Hello! I try to use DSNiff with my FreeBSD 5.4-PRE and bge NIC. Unfortunatelly it does no work. My supposition is that the root of problem is bad tcp checksums (as shown by tcpdump). And DSNiff (and underlaying libnids) are checking for checksums. As I undrestand, bge has txcsum flag, so tcp stack does not computes checksum itself. Am I right? And may I turn off txcsum flag without modifying bge driver? -- With respect, Boris
