https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=15038 --- Comment #9 from Xiaochuan Sun --- You are right. I changed f1ap.cnf according to xxx.asn file, the UL RRC message transfer message can be decoded correctly. The below command is wrriten in the header of packet-f1ap.c file. It can generate new packet-f1ap.c file. Hope we don't need to change xxx.cnf file manually one day. "asn2wrs.py -p f1ap -c ./f1ap.cnf -s ./packet-f1ap-template -D . -O ../.. F1AP-CommonDataTypes.asn F1AP-Constants.asn F1AP-Containers.asn F1AP-IEs.asn F1AP-PDU-Contents.asn F1AP-PDU-Descriptions.asn" -- You are receiving this mail because: You are watching all bug changes.___ Sent via:Wireshark-bugs mailing list Archives:https://www.wireshark.org/lists/wireshark-bugs Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-bugs mailto:wireshark-bugs-requ...@wireshark.org?subject=unsubscribe

https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=15038 --- Comment #8 from Pascal Quantin --- First of all you need to regenerate paxket-f1ap.c from the ASN.1 description (using the corresponding CMkae command generat-f1ap-something, I do not remember it's exact name) and modify the F1AP.cnf file to match your updated specification and iterates until it compiles. Unless you are familiar with ASN.1 based dissector, it might take you some time. Good luck. -- You are receiving this mail because: You are watching all bug changes.___ Sent via:Wireshark-bugs mailing list Archives:https://www.wireshark.org/lists/wireshark-bugs Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-bugs mailto:wireshark-bugs-requ...@wireshark.org?subject=unsubscribe

https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=15038 --- Comment #6 from Xiaochuan Sun --- Created attachment 16529 --> https://bugs.wireshark.org/bugzilla/attachment.cgi?id=16529&action=edit F1AP-V04.00.asn Actually I have used extract_asn1_from_spec.pl to parse F1AP-V04.00.asn and generated F1AP-CommonDataTypes.asn F1AP-Constants.asn F1AP-Containers.asn F1AP-IEs.asn F1AP-PDU-Contents.asn F1AP-PDU-Descriptions.asn. Then add these asn files into epan/dissectors/asn1/f1ap directory and rebuilt wireshark. So the wireshark dissector should be aligned with F1AP-V04.00.asn spec. -- You are receiving this mail because: You are watching all bug changes.___ Sent via:Wireshark-bugs mailing list Archives:https://www.wireshark.org/lists/wireshark-bugs Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-bugs mailto:wireshark-bugs-requ...@wireshark.org?subject=unsubscribe
