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. |
