| 4 | About
|
|---|
| 5 |
|
|---|
| 6 | This program converts a libpcap network trace file (produced by ethereal or
|
|---|
| 7 | another pcap-aware network analyzer) into a output suitable for nbench. The
|
|---|
| 8 | only option it takes it -i which supresses any reads/writes/closes that use a
|
|---|
| 9 | FID that does not have a corresponding ntcreateandx
|
|---|
| 10 |
|
|---|
| 11 | Limitations
|
|---|
| 12 |
|
|---|
| 13 | 1) pcap2nbench does not handle ip fragmentation. You should not normally see
|
|---|
| 14 | very much fragmentation so this should not really affect a workload.
|
|---|
| 15 | 2) unicode on the wire is not supported.
|
|---|
| 16 | 3) only a limited number of SMBs are supported. Namely: NtCreateAndX,
|
|---|
| 17 | ReadAndX, WriteAndX, and Close. In addition, not all WCTs are supported on
|
|---|
| 18 | each of these SMBs.
|
|---|
| 19 |
|
|---|
| 20 | Future Work
|
|---|
| 21 |
|
|---|
| 22 | It would be nice to use Samba or Ethereal's parsing code to handle the SMBs.
|
|---|
| 23 | At first glance, this seemed non-trivial. It would also be nice to handle some
|
|---|
| 24 | Trans2 SMBs specifically QueryFileInfo and QueryPathInfo.
