Wireshark uses 3GPP TS 25.453 V11.0.0 specification for PCAP. I would like to use 3GPP TS 25.453 V9.1.0 for Wireshark decoding. Is it possible to rebuild Wireshark with a change of protocol Spec. How can I di this.

Thank you in advance

Are you sure you need an earlier version? Most of the time it's backwards compatible. If you need to rebuild you could check the history to see if the dissector was built with the version you require. If not you need to replace the asn1 files under dissectors/asn1/pcap with the version you want and adjust the .cnf file to fit that version. Then rebuild the dissector and rebuild wireshark. The method depends a bit on the OS you want to build for.

Anders, thank you for your help.

Unfortunately PCAP is encoded in Aligned Packed Encoding Rules (APER) ASN1.1 that is very sensitive to specification Version.

What is the ".cnf" file purpose?

Thank you in advance
