+pcap2nbench
+-----------
+
+About
+
+This program converts a libpcap network trace file (produced by ethereal or
+another pcap-aware network analyzer) into a output suitable for nbench. The
+only option it takes it -i which supresses any reads/writes/closes that use a
+FID that does not have a corresponding ntcreateandx
+
+Limitations
+
+1) pcap2nbench does not handle ip fragmentation. You should not normally see
+ very much fragmentation so this should not really affect a workload.
+2) unicode on the wire is not supported.
+3) only a limited number of SMBs are supported. Namely: NtCreateAndX,
+ ReadAndX, WriteAndX, and Close. In addition, not all WCTs are supported on
+ each of these SMBs.
+
+Future Work
+
+It would be nice to use Samba or Ethereal's parsing code to handle the SMBs.
+At first glance, this seemed non-trivial. It would also be nice to handle some
+Trans2 SMBs specifically QueryFileInfo and QueryPathInfo.
