Hi,=20

how can I understand following output from "tcpdump -p", at that time, I am "dd" a file into a nfs mount point. Can anyone send me a reference link to me? especially what's the meaning of "frag 55141:1292@2960", what's "DF"...

11:40:16.499209 192.168.0.148.3554257722 > 192.168.0.90.nfs: 1472 write [|nfs] (frag 55140:1480@0+)
