Hi ,

 

I had to include some RANAP messages  in my dissector.

I have included in the following way:

 

dissect_xxx_msg(tvbuff_t *tvb,int offset,proto_tree *macic_tree,packet_info *pinfo)

{

guint8 *buf = ep_alloc(10240);

tvbuff_t *ranap_tvb;

int i;

asn1_ctx_t actx;

 

offset = add_IE_indicator(tvb, offset, macic_tree); /* To add IE Indicator */

offset = add_IE_length(tvb, offset, macic_tree);    /* To add IE length    */

 

ranap_tvb = tvb_new_real_data(buf,i,i);

tvb_set_child_real_data_tvbuff(tvb,ranap_tvb);

add_new_data_source(pinfo, ranap_tvb, "RANAP OVER MACIC");

asn1_ctx_init(&actx, ASN1_ENC_PER, TRUE, pinfo);

offset= dissect_ranap_ResetAcknowledge(ranap_tvb, offset, &actx, macic_tree, hf_macic_ranap_resetAcknowledge);

…………….

………

Remaining part of the msg continues..

}

I have included the appropriate headers : packet_ranap.h, packet_per.h, packet_ber.h etc etc…

I am getting a run-time error mentioned below:

 

undefined symbol: dissect_ranap_ResetResource

 

Any other place that I have to declare the functions ????

Please help…..

 

Regards,

Tarani

Hi Anders,

 

To include the RANAP messages in my dissector, I have done the following:

 

1.In ranap.cnf under #.EXPORTS, I have added the message id s which I want to export.

2.In packet-ranap.h, I have included the corresponding functions of the messages which I want to add.

3.In my dissector , I have included packet-ranap.h , packet-per.h and called the functions appropriately.

 

But I am getting errors due to some linking problems.

 

error: `actx' undeclared (first use in this function)

error: (Each undeclared identifier is reported only once

 

I have not defined asn1_ctx_t *actx in my dissector as I have included the appropriate headers.

 

Can you please help???

 

Regards,

Tarani

Hi Anders,

 

Thanks for the information. The dissector is propreitary , hence I cant include it in Wireshark.

 

I will include RANAP messages in the way you have mentioned.

But then , I will have a tough time forming packets for testing . Any clue how can I form the packets.

 

Thanks in advance.

 

Regards,

Tarani

Subject: Including ASN.1 format coding in a C dissector

 

Hi ,

 

I have written  a dissector for a protocol which has a coding standard of Tag-Length-Value. Now in this dissector , I have to add some messages of RANAP protocol which has a coding standard in ASN.1 format.Already the dissector for RANAP is available in the wireshark. Now:

 

1.Can I call the existing dissector for those particular messages??? If so how do I do that??

2. If I want to include it normally in my dissector, how can I convert the ASN.1 format to obtain the tag and lengths of  individual parameters??

 

Can anybody please help??
