Hi,
I was
refering to the ranap.cnf file. But I suspect that the problem is that you have
built your dissector as a plugin and
need
to have the ranap functions exported trough libethereal.def, try to add them
there possibly you need yo add export
in the
ranap.h file like:
#line
1 "packet-ranap-exp.h"
extern const value_string ranap_Service_Handover_vals[]; extern const value_string ranap_TargetID_vals[]; extern int dissect_ranap_ResetAcknowledge(tvbuff_t *tvb _U_, int offset _U_, asn1_ctx_t *actx _U_, proto_tree *tree _U_, int hf_index _U_); extern int dissect_ranap_ResetResource(tvbuff_t *tvb _U_, int offset _U_, asn1_ctx_t *actx _U_, proto_tree *tree _U_, int hf_index _U_); extern int dissect_ranap_EncryptionInformation(tvbuff_t *tvb _U_, int offset _U_, asn1_ctx_t *actx _U_, proto_tree *tree _U_, int hf_index _U_); extern int dissect_ranap_IntegrityProtectionInformation(tvbuff_t *tvb _U_, int offset _U_, asn1_ctx_t *actx _U_, proto_tree *tree _U_, int hf_index _U_); extern int dissect_ranap_Service_Handover(tvbuff_t *tvb _U_, int offset _U_, asn1_ctx_t *actx _U_, proto_tree *tree _U_, int hf_index _U_); extern int dissect_ranap_TargetID(tvbuff_t *tvb _U_, int offset _U_, asn1_ctx_t *actx _U_, proto_tree *tree _U_, int hf_index _U_); you'll
ned to do this by hand as asn2wrs does not do this
automatically.
You
are probably better off building your dissector as a "normal" dissector avoiding
this kind of problems. As you are changing the main code to make
your
plugin
to work you need to disrtribute a complete Wireshark package any way not only
the Plugin. Note that any one that gets this package
can
request the source code under the GPL license.

, Can you specify
which .cnf file, because we don’t have a .cnf file in my plugin
directory.. Also , do we need to
make any changes in makefie.am, makefile.common
etc?? Regards, Tarani

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
From:
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

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?? //Tarani
