NTAPI version error: Got 2, expect 1

[ion9]

Hello, I'm trying to work out a way to get a napatech card working with pf_ring so i can fan out to bro workers

This is what the error looks like

root@pcap01:~/pfring/userland/examples# ./pfcount -i nt:stream0
NT_Init() failed: NT_Init called with version mismatch
pfring_open error [No such device] (pf_ring not loaded or interface nt:stream0 is down ?)

I'm thinking it's something in the lib for opening the napa stream

Things I found that may help

root@pcap01:/opt/napatech3/include/ntapi# cat errorcodes.h |grep 'version mismatch'
NT_MAKE_ERROR2(NT_ERROR_NTAPI_VERSION_MISMATCH,             "NT_Init called with version mismatch") \

And

root@pcap01:/opt/napatech3/include/ntapi# cat-just-the-good-part ntapi.h

/**
 * @file
 *
 * This header file contains NTAPI function prototypes
 */
#ifndef __NTAPI_H__
#define __NTAPI_H__

/**
 * @brief Initializes the NTAPI library
 *
 * This function <em>must</em> be called prior to any other
 * NTAPI function. It will initialize the NTAPI library and perform
 * compatibility checks based on the version applied.
 * The version is used to indicate to NTAPI what version of the API the
 * application supports and will enable NTAPI to act on this and adapt to that
 * version of the API if possible. This means that if the application is compiled
 * to e.g. version 1 of the API and the current API is version 9, NT_Init will
 * check if it is possible to enable backward compatibility to version 1 and
 * thereby allow the application to run on a version 9 library with version 1 API.
 *
 * @param[in] version  The version that the calling application supports
 *
 * @retval  NT_SUCCESS     Success
 * @retval  !=0            Error
 */
int NT_Init(uint32_t version);

and this

root@pcap01:/opt/napatech3/include/ntapi# cat version.h 
/**
 * @file
 *
 * This is the header file of the NTAPI_VERSION define.
 */
#ifndef __VERSION_H__
#define __VERSION_H__

/**
 * This define is used to ensure that applications can control
 * what API version should be supported by the NTAPI library.
 * The NTAPI library will via NT_Init, check if backward compatibility
 * to NTAPI_VERSION can be ensured and convert all return structures
 * to this version if possible. If it is not possible, NT_Init() will fail.
 */
#define NTAPI_VERSION 1

#endif

attached is the step by step build and test of the system

@ion9 please ask Napatech to provide you latest library (we have v.5.0.2 atm)

[ion9]

Thank you.

[ion9]

Just got word back from napatech and the latest release is ntanl_3.2, with an initial ntanl_5.x release; however it has a limited feature set and is not ready to provide to customers just yet.

in reviewing the change log i see:

2015-11-26 PF_RING 6.2

• Napatech module compatibility with ntanl v.4.0.1

I'll try building PF_RING 6.0.3 with ntanl_3.2.

[cardigliano]

Yes v.4.0.1 is supported, using 3.2 you should get a version mismatch error from the napatech library.. anyway worth give it a try

After that I could build the lib

Then I got

NT_NetRxOpen() failed: When running PCAP header, the packet interface is not supported
Unable to enable ring :-(

To fix that the ntservice.ini has to have

TimestampFormat = NATIVE
PacketDescriptor = NT

as PCAP discriptor dose not work

oh joy, now to get the license file working....
